I. EXECUTIVE SUMMARY

This memorandum synthesizes the findings from Dr. Ingrid Lautner's expert report (served August 19, 2024) and Brindoval Forensic Consulting LLC's metadata verification analysis to assess the strength of Redstone Gaming Corp.'s ("Redstone") defense across all 37 visual assets challenged by Luminos Interactive LLC ("Luminos") in this action. We have conducted an asset-by-asset comparison analysis, cross-referencing Dr. Lautner's visual-comparison framework with the independent-creation evidence preserved in Redstone's version-control systems and the scènes à faire analysis applicable to each category of challenged content. This memo provides a comprehensive treatment of each asset category, identifies the four assets that warrant heightened attention, evaluates the fair use defense, critiques the opposing expert's methodology, and provides our recommendation regarding dispositive motion practice.

Bottom-Line Conclusion. Of the 37 assets Luminos challenges, only four (4) exceed a 40% similarity index — the recognized threshold of concern in visual-comparison analysis — and none exceeds 52%. The overwhelming majority of similarities between the challenged Ironclad Dominion assets and their purported Shardfall Chronicles counterparts are attributable to unprotectable genre conventions (scènes à faire), including standard fantasy-RPG visual tropes such as crystalline cave textures, medieval plate-armor silhouettes, radial menu interfaces, and fantasy landscape compositions. The independent-creation evidence drawn from the ironclad-main Git repository is robust and, as of the date of this memorandum, uncontroverted: all four above-threshold assets were committed to the repository months before Shardfall Chronicles was released or made publicly available.

Recommendation. Redstone should file a Motion for Summary Judgment on fair-use grounds, supplemented by independent creation and scènes à faire arguments. We recommend a target filing date of September 9, 2024, consistent with the case scheduling order and discovery completion. The motion should be accompanied by supporting declarations from Jordan Kessler (VP of Creative Development), Seo-Yeon Park (Lead Character Artist), Dr. Ingrid Lautner (expert), and Nathan Rourke (Brindoval Forensic Consulting LLC), together with a comprehensive Statement of Undisputed Material Facts. We further recommend filing a concurrent Daubert motion to exclude the testimony of Luminos's expert, Dr. Calvin Yates, whose report suffers from significant methodological deficiencies detailed in Section VII below.

Note Regarding Opposing Expert. Dr. Calvin Yates, retained by Luminos's counsel at Hargrove, Tanaka & Whitmore LLP, served his expert report on August 19, 2024. Dr. Yates reached contrary conclusions, opining that 14 of the 37 assets exceed 60% similarity. As discussed at length in Section VII, Dr. Yates's inflated similarity scores are attributable to a fundamentally flawed single-metric pixel-comparison methodology that fails to normalize for resolution, aspect ratio, or color space; fails to exclude unprotectable scènes à faire elements from the similarity calculation; and fails to account for the independent-creation timeline established by the ironclad-main repository. This memo identifies specific methodological deficiencies suitable for cross-examination and Daubert challenge.

II. BACKGROUND

A. The Underlying Works

Shardfall Chronicles. Shardfall Chronicles is an indie action-RPG developed by Luminos Interactive LLC, a Nevada limited liability company founded by Tobias Crane (Founder and Managing Member) and Elara Whitfield (Art Director and Co-Founder). The game was released on March 22, 2021, on PC (via the Steam digital distribution platform). Shardfall Chronicles features a dark-fantasy aesthetic characterized by crystalline environmental textures, stylized armored characters rendered in a painterly art style, and a distinctive radial menu user interface for ability selection and inventory management. The game received generally favorable reviews from independent gaming publications, with particular praise for its environmental art direction. Luminos registered the copyright in the game's visual assets with the United States Copyright Office on June 8, 2021 (Registration No. VA 2-254-781).

As of the date of this memorandum, Shardfall Chronicles has sold approximately 185,000 lifetime units at a manufacturer's suggested retail price ("MSRP") of $24.99, yielding estimated gross revenue of approximately $4.62 million. Luminos's FY 2023 revenue, as reflected in its financial statements prepared by Whitmore & Pine CPAs and produced in discovery, was approximately $2.1 million, a figure that includes both direct sales revenue and ancillary merchandise and licensing income. Luminos is a small independent studio with fewer than 20 full-time employees.

Ironclad Dominion. Ironclad Dominion is a AAA multiplayer tactical RPG developed by Redstone Gaming Corp., a Delaware corporation with its principal place of business in Henderson, Nevada. The game was created under the creative leadership of Jordan Kessler (Vice President of Creative Development) and Seo-Yeon Park (Lead Character Artist), among a team of approximately 340 artists, designers, programmers, and other development personnel. Ironclad Dominion was released on November 14, 2022, on PC (via Steam and Redstone's proprietary launcher), PlayStation 5, and Xbox Series X|S. The game features a mechanized-fantasy and steampunk visual environment — a thematic vocabulary fundamentally distinct from Shardfall Chronicles's dark-fantasy aesthetic. Ironclad Dominion's art direction is characterized by armored warrior characters with industrial and mechanical design elements, steampunk environmental assets, and a contextual radial HUD system.

Development of Ironclad Dominion commenced in Q1 2020. The first commit in the game's primary version-control repository ("ironclad-main") is dated February 12, 2020 — approximately thirteen (13) months before Shardfall Chronicles was released. The game generated $312 million in revenue in its first 12 months of commercial availability, making it one of the top-selling RPG titles of 2022–2023. Ironclad Dominion has been the subject of two post-launch expansion packs and an ongoing live-service content model.

B. Luminos's Claims

Luminos filed its Complaint in this action on March 18, 2024, in the United States District Court for the District of Nevada, Case No. 2:24-cv-00587-RWL, before the Honorable Rebecca W. Langford. The case was assigned to Judge Langford's docket following random assignment, and no reassignment has occurred.

Luminos alleges that 37 specific visual assets in Ironclad Dominion are "substantially similar" to corresponding assets in Shardfall Chronicles. The 37 challenged assets fall into four categories:

• Character Armor Designs: 12 assets (Assets 1–12), comprising chest plates, pauldrons, gauntlets, helmets, greaves, and other components of in-game character armor sets.

• Environmental Crystal Textures: 9 assets (Assets 13–21), comprising cave wall textures, crystal formation props, and crystalline environmental elements.

• UI Icon Sets: 8 assets (Assets 22–29), comprising user interface elements such as inventory grids, health/mana indicators, radial ability menus, minimaps, and associated iconography.

• Background Matte Paintings: 8 assets (Assets 30–37), comprising full-screen background illustrations used for loading screens, menu backgrounds, and distant environmental vistas.

Luminos's Complaint asserts claims for copyright infringement under 17 U.S.C. §§ 106 and 501. Luminos seeks actual damages of $28.5 million, calculated on an apportioned-profits theory: Luminos contends that 9.13% of Ironclad Dominion's $312 million first-year revenue is attributable to the allegedly infringing visual assets, yielding approximately $28.5 million ($312M × 9.13% ≈ $28.5M). The 9.13% apportionment figure was derived from a subjective assertion by Tobias Crane in his declaration filed in support of the Complaint, not from any consumer survey, conjoint analysis, or other empirically validated methodology. Luminos also seeks injunctive relief prohibiting Redstone from further distribution of Ironclad Dominion in its current form, statutory damages in the alternative under 17 U.S.C. § 504(c), and attorney's fees under 17 U.S.C. § 505.

C. Expert Engagement

Redstone's Expert — Dr. Ingrid Lautner. Dr. Ingrid Lautner was retained by Calderwood & Harkness LLP on behalf of Redstone pursuant to a retention letter dated May 28, 2024. Dr. Lautner is a Professor of Digital Media and Game Design at Pacific Western University, where she has taught since 2012. Her areas of specialty include visual asset comparison methodologies, procedural generation systems, and transformative design in interactive media. Dr. Lautner has published over 40 peer-reviewed articles in journals including the Journal of Digital Media Studies, the ACM Transactions on Graphics, and Computer Graphics Forum. She has been qualified as an expert witness in seven prior copyright actions involving digital visual content, including two in the District of Nevada. Dr. Lautner is compensated at a rate of $650 per hour for her work in this matter.

Dr. Lautner's expert report was completed and served on August 19, 2024, the expert-report deadline established by the Court's scheduling order. Her report encompasses a detailed visual-comparison analysis of all 37 challenged asset pairs, employing a multi-layer comparison methodology described in Section III below.

Brindoval Forensic Consulting LLC. Brindoval Forensic Consulting LLC was retained as a non-testifying consulting expert to perform metadata analysis and verification of Redstone's art pipeline and version-control logs. The lead consultant on the engagement is Nathan Rourke, a certified digital forensics examiner with over 15 years of experience in software repository analysis and metadata verification. Brindoval's offices are located at 3310 Wilshire Boulevard, Suite 700, Los Angeles, California 90010. Brindoval's work product has been incorporated into Dr. Lautner's expert report and may also serve as the basis for a separate declaration by Mr. Rourke in support of the anticipated Motion for Summary Judgment.

Luminos's Expert — Dr. Calvin Yates. Luminos's expert is Dr. Calvin Yates, an independent digital forensics consultant and former Associate Professor at Riverbend Institute of Technology (a position he held from 2015 to 2021). Dr. Yates specializes in pixel-level comparison of game textures and asset metadata forensics. He was retained by Hargrove, Tanaka & Whitmore LLP, Luminos's counsel of record (Daniel Hargrove, lead attorney; Megan Forsyth, associate). Dr. Yates's expert report was served on August 19, 2024, contemporaneously with Dr. Lautner's report. His report reaches conclusions sharply at odds with Dr. Lautner's findings, as discussed in detail in Section VII.

D. Evidentiary Foundation

The evidentiary foundation for the analysis set forth in this memorandum rests on several categories of evidence, all of which have been produced in discovery or obtained through depositions:

Version-Control Repository. Brindoval verified the integrity and timestamps of all 14,208 commits in the ironclad-main Git repository spanning from February 12, 2020, through October 2022. The verification process included hash-chain integrity analysis (confirming that SHA-1 commit hashes form an unbroken chain from the initial commit through the final pre-release commit), server-side log correlation (cross-referencing commit timestamps against Redstone's internal build server logs and backup timestamps), and author-attribution verification (confirming that commit authors correspond to known Redstone employees active during the relevant periods). Brindoval's analysis confirmed the integrity of the repository: there is no evidence of post-hoc tampering, backdating, or artificial insertion of commits.

Document Production. Redstone produced 42,316 pages of documents in this action (Bates Nos. RGC-000001 through RGC-042316), served on July 8, 2024. The production includes concept art archives for all character armor designs, environmental textures, UI elements, and matte paintings; internal design review presentations from the biweekly art review meetings conducted throughout Ironclad Dominion's development cycle; Git logs and commit messages; email correspondence among the art team; and licensing records for third-party assets and procedural generation tools.

Depositions. The following depositions of key witnesses have been completed:

• Tobias Crane (Luminos Founder and Managing Member): Deposed July 22, 2024. Mr. Crane testified regarding the development timeline for Shardfall Chronicles, the sources of inspiration for the game's visual design, the marketing and promotional activities undertaken prior to the game's release, and the basis for Luminos's damages calculation.

• Elara Whitfield (Luminos Art Director and Co-Founder): Deposed July 29, 2024. Ms. Whitfield testified regarding the specific creative process behind the 37 challenged Shardfall Chronicles assets, the artistic references and mood boards used during development, and the availability (or unavailability) of the game's visual assets prior to the March 2021 release.

• Jordan Kessler (Redstone VP of Creative Development): Deposed August 5, 2024. Mr. Kessler testified regarding the independent creative conception and development of Ironclad Dominion, the studio's art direction philosophy, the absence of any access to or awareness of Shardfall Chronicles during the design of the game's core visual assets, and the internal art review pipeline that generated contemporaneous documentation of the creative process.

• Seo-Yeon Park (Redstone Lead Character Artist): Deposed August 12, 2024. Ms. Park testified regarding the specific design process for the character armor assets, the steampunk and industrial design references used by the art team, and the procedural generation tools employed for environmental textures, including crystal formations.

III. METHODOLOGY — DR. LAUTNER'S VISUAL COMPARISON FRAMEWORK

A. Pixel-Level Similarity Index

Dr. Lautner employed a multi-layer comparison methodology that represents the current state of the art in digital visual asset comparison analysis. Her methodology integrates four distinct analytical layers, each capturing a different dimension of visual similarity:

1. Normalized Structural Similarity (SSIM). Each asset pair was rendered at a standardized resolution (2048 × 2048 pixels for textures and matte paintings; native resolution for UI elements) and compared using the Structural Similarity Index Measure ("SSIM"), a perceptual metric that evaluates luminance, contrast, and structural information. Critically, Dr. Lautner normalized all renders for resolution and aspect ratio prior to comparison — a step that Dr. Yates omitted (see Section VII).

2. Color Histogram Comparison. Dr. Lautner extracted color histograms in the CIELAB color space (a perceptually uniform color model) for each asset pair and computed histogram intersection values. This layer captures the degree of overlap in the color palettes used by the two assets, independent of their spatial arrangement.

3. Edge-Detection Silhouette Overlay. Using Canny edge detection, Dr. Lautner generated silhouette maps for each asset and overlaid them to assess the degree of structural correspondence in the shapes and contours of the compared elements. This layer is particularly informative for character armor and environmental prop comparisons, where overall form and silhouette are key elements of visual identity.

4. Feature-Point Matching. Dr. Lautner employed Scale-Invariant Feature Transform ("SIFT") feature-point detection and matching to identify and quantify the number of corresponding keypoints between asset pairs. Feature-point matching captures fine-grained details such as surface ornamentation, texturing patterns, and micro-structural similarities.

Each asset pair received a composite "similarity index" on a 0–100% scale, calculated as a weighted average of the four analytical layers (with weights calibrated to reflect the relative importance of each layer in the context of visual-art copyright comparison, as described in Dr. Lautner's report at pages 14–18). Dr. Lautner's calibration weights were developed through her prior academic research and have been published in peer-reviewed venues.

The similarity index should be interpreted according to the following ranges, which Dr. Lautner derived from empirical studies of known-copying and known-independent-creation data sets:

• Below 30%: Negligible resemblance. Similarities at this level are consistent with coincidence, shared medium constraints, or the most basic elements of the genre.

• 30–40%: Incidental overlap consistent with shared genre conventions. Assets in this range may share general compositional features or thematic elements, but the degree of similarity does not, standing alone, support an inference of copying.

• Above 40%: Warrants closer scrutiny. Assets exceeding this threshold require individualized analysis to determine whether the similarities are attributable to protectable creative expression or to unprotectable genre conventions, functional constraints, or independent creation.

• Above 70%: Typically indicative of copying. Assets in this range exhibit a degree of correspondence that, absent an independent-creation defense, would support an inference that one work was derived from the other.

It bears emphasis that no asset in this matter approaches the 70% threshold. The highest similarity index recorded across all 37 asset pairs is 52% (Asset 18), which falls well below the range typically associated with a finding of copying.

Contrast with Dr. Yates's Methodology. Dr. Yates's methodology is discussed in detail in Section VII. At a summary level, the critical distinction is that Dr. Yates employed a single-metric pixel-comparison approach without normalization for resolution, aspect ratio, or color space, and without exclusion of unprotectable scènes à faire elements. These methodological failures systematically inflate Dr. Yates's similarity scores, producing results that are not reliable indicators of protectable-expression overlap.

B. Transformative-Use Evaluation

For each asset pair, Dr. Lautner additionally assessed whether the Ironclad Dominion version constitutes a transformative reworking of the visual concepts at issue. This assessment examined four dimensions of transformation:

• Contextual Transformation: Whether the asset serves a different narrative or gameplay function in Ironclad Dominion than the corresponding asset serves in Shardfall Chronicles. For example, crystalline formations that serve as ambient environmental decoration in Shardfall Chronicles function as harvestable resources integrated into the gameplay economy of Ironclad Dominion.

• Aesthetic Vocabulary Shift: Whether the asset has been reworked into Ironclad Dominion's mechanized-steampunk visual language, as distinct from Shardfall Chronicles's dark-fantasy aesthetic. This dimension captures the degree to which the challenged asset reflects the distinctive artistic identity of the accused work.

• Narrative Function: Whether the asset carries different narrative meaning or communicates different themes in Ironclad Dominion — for instance, whether a crystal texture that symbolizes magical purity in Shardfall Chronicles has been reimagined as an industrial resource in Ironclad Dominion's steampunk world.

• Compositional Structure: Whether the spatial arrangement, proportions, and visual hierarchy of the asset differ between the two works.

Dr. Lautner's transformative-use evaluation supports the conclusion that, across all four categories of challenged assets, Ironclad Dominion's visual content represents a fundamentally different artistic vision — one rooted in mechanized-industrial aesthetics — that repurposes generic fantasy motifs in a transformative manner.

C. Scènes à Faire Overlay

As a third analytical layer, Dr. Lautner identified which elements of visual similarity between the asset pairs are attributable to genre-standard tropes — that is, elements that are standard, stock, or common to the fantasy-RPG genre and are therefore unprotectable under the scènes à faire doctrine. For each asset pair, Dr. Lautner documented the specific elements that fall within the scènes à faire category and excluded those elements from her assessment of protectable-expression overlap.

Dr. Lautner's scènes à faire analysis draws on a comprehensive survey of commercially released fantasy-RPG titles spanning the period from 2000 to 2023. Her report identifies specific prior works exhibiting each of the challenged visual elements — crystalline cave formations, radial menu interfaces, medieval plate-armor silhouettes, and standard matte-painting compositions for fantasy landscapes — and documents the pervasiveness of these elements across the genre. This survey is detailed in Appendix C of Dr. Lautner's report and encompasses over 60 commercially released titles.

IV. ASSET-BY-ASSET COMPARISON RESULTS

This section presents the detailed asset-by-asset comparison results across all four categories of challenged visual elements. For each category, we provide an overview table summarizing the similarity indices, followed by individualized analysis of each asset pair, and concluding with a scènes à faire analysis applicable to the category as a whole.

A. Character Armor Designs (Assets 1–12)

Overview Table. The following table summarizes the similarity index results for all 12 character armor design pairs. Each asset is identified by its Luminos exhibit designation and the corresponding Ironclad Dominion asset identifier.

Summary: All 12 character armor design pairs fall within a similarity index range of 18% to 41%. Only one asset — Asset 7 (Crystal Warden Helmet vs. Prism Knight Helm) — exceeds the 40% threshold, registering at 41%. Nine of the 12 assets fall below the 30% threshold, indicating negligible resemblance. The mean similarity index for the character armor category is 27.7%.

Detailed Analysis of Each Asset (Assets 1–12). Asset 1: Obsidian Sentinel Chest Plate vs. Iron Vanguard Torso Armor — Similarity Index: 28%. The Shardfall Chronicles "Obsidian Sentinel" chest plate is a segmented plate-armor torso piece rendered in dark, matte-obsidian tones with subtle crystalline accents along the sternum. The Ironclad Dominion "Iron Vanguard" torso armor is likewise a segmented plate construction, but incorporates visible riveting along plate seams, interlocking gear motifs on the shoulder attachment points, and copper pipe accents running from the back plate to the collar guard, all consistent with Ironclad Dominion's steampunk aesthetic. The segmented plate construction shared by both assets is a ubiquitous design element in fantasy armor and is not protectable expression. Dr. Lautner's SSIM analysis shows significant structural divergence in the proportions and contours of the two pieces, and the color histogram comparison reflects entirely different palettes (obsidian-black/crystal-blue vs. burnished-iron/copper-orange). The first commit for Iron Vanguard art in the ironclad-main repository is dated March 15, 2020, predating Shardfall Chronicles' release by over one year. This asset presents no concern from a substantial-similarity perspective.

Asset 2: Frostguard Pauldrons vs. Steamwarden Pauldrons — Similarity Index: 22%. The resemblance between these two pauldron designs is minimal, limited to the generic rounded-dome shape common to virtually all fantasy shoulder armor. The Shardfall version features frost-etched detailing and crystalline inlays; the Ironclad version features exhaust vents and piston mechanisms. The 22% similarity is attributable entirely to the shared pauldron silhouette, a stock element of the genre.

Asset 3: Dragonscale Mail Shirt vs. Boilerplate Scale Vest — Similarity Index: 31%. Both assets employ a layered scale-mail texture — individual overlapping scales covering the torso. Dr. Lautner notes that scale-mail armor is one of the oldest and most commonly depicted armor types in fantasy media, appearing in historical illustrations dating to medieval manuscripts and in virtually every fantasy RPG released in the last two decades. The Shardfall version uses organic, reptilian-textured scales with iridescent shading; the Ironclad version uses stamped-metal scales with visible forge marks and industrial patina. The 31% similarity is driven by the shared scale-mail pattern, which is a genre-standard trope. The textural and material rendering differences are substantial.

Asset 4: Shadow Reaver Greaves vs. Piston-Leg Greaves — Similarity Index: 25%. Both are shin-guard armor pieces with articulated knee joints, a functional requirement for any character armor that must accommodate walking and running animations. The Ironclad version integrates hydraulic piston mechanisms at the knee, consistent with the game's mechanical-augmentation theme. The resemblance is driven by the anatomical constraints of leg armor design and does not reflect protectable creative expression.

Asset 5: Moonsilver Bracers vs. Copper Coil Bracers — Similarity Index: 19%. Minimal resemblance. The Shardfall bracers are slender, elegant forearm guards with lunar-glyph engravings; the Ironclad bracers are bulky, industrialized forearm pieces wrapped in copper coils and fitted with pressure gauges. The 19% similarity reflects only the shared functional form of a forearm armor piece.

Asset 6: Beast Warden Gauntlets vs. Mech-Claw Gauntlets — Similarity Index: 33%. Both gauntlet designs feature claw-like finger articulation — an elongated, tapered finger structure with segmented joints that evokes a predatory-animal aesthetic. This design element is a genre convention for the "beast knight" or "feral warrior" archetype, which appears in numerous prior fantasy RPGs. Despite the shared claw-like articulation, the Ironclad version employs pneumatic joint mechanisms, exposed wiring, and brass housings at each knuckle, fundamentally changing the visual character of the gauntlets from organic-bestial to mechanical-predatory. Dr. Lautner identified at least eight prior commercial RPG titles featuring gauntlets with substantially similar claw articulation, establishing that this element is a scènes à faire trope.

Asset 7: Crystal Warden Helmet vs. Prism Knight Helm — Similarity Index: 41% — EXCEEDS 40% THRESHOLD. This asset presents the closest similarity of any character armor pair and is one of only four assets across all 37 that exceeds the 40% threshold. The Shardfall Chronicles "Crystal Warden" helmet features a narrow visor slit flanked by angular crystalline projections extending upward from the brow line, giving the helmet a crown-like silhouette. The Ironclad Dominion "Prism Knight" helm shares the general configuration of a visor slit flanked by angular projections, which accounts for the elevated similarity index.

However, the Ironclad version introduces several significant design elements absent from the Shardfall helmet: (i) a mechanical retracting visor mechanism with visible hinge points and a locking lever on the right temple; (ii) brass-coil trim along the projections, replacing the smooth crystal surfaces of the Shardfall version; (iii) a darker, more muted color palette (gunmetal gray with amber accent lighting) compared to the Shardfall version's luminescent cyan-crystal finish; and (iv) industrial grommets and ventilation slits along the crown. Brindoval's metadata analysis confirms that the Prism Knight helm concept art was committed to the ironclad-main repository on June 4, 2020 — nine months before Shardfall Chronicles was released. This independent-creation evidence eliminates any inference of access-based copying.

From a transformative-analysis perspective, Dr. Lautner opines that the Prism Knight helm represents a mechanical and industrial reworking of the generic "crystal-adorned helmet" motif. The crystalline projections in the Ironclad version serve a different narrative purpose — they are described in the game's lore as prismatic energy conductors integrated into the warrior's powered armor suit, rather than magical crystalline growths. The aesthetic meaning of the helmet is fundamentally different: industrial utility rather than mystical ornamentation.

Even at 41%, this asset falls well below the 70% threshold typically indicative of copying. Combined with the independent-creation timeline and the transformative reworking, this asset does not support an inference of infringement.

Asset 8: Flameguard Boots vs. Forge-Tread Sabatons — Similarity Index: 24%. Both are armored foot pieces with reinforced toe caps — a standard element of any full plate-armor set. The Shardfall version features flame-motif engravings; the Ironclad version features treaded soles and exhaust ports. Minimal resemblance beyond the generic form factor.

Asset 9: Stonewall Cuirass vs. Ironhull Cuirass — Similarity Index: 18%. The lowest similarity index in the character armor category. The two assets share only the most basic cuirass shape. The Shardfall version is a naturalistic stone-textured breastplate; the Ironclad version is a riveted iron hull plate with ship-hull aesthetics. No meaningful resemblance.

Asset 10: Nightshade Cloak Armor vs. Smoke Shroud Plating — Similarity Index: 29%. Both assets combine a partial breastplate with draped fabric elements, creating a "cloaked warrior" silhouette. This combination is a well-established archetype in the fantasy-RPG genre (the rogue, assassin, or ranger class archetype). The fabric rendering, plate detailing, and color palettes are entirely distinct. The 29% similarity is attributable to the shared archetype.

Asset 11: Ashborn Shoulder Guard vs. Rivet-Plate Spaulder — Similarity Index: 35%. Both assets feature an asymmetric shoulder armor design — a single oversized shoulder plate worn on the dominant arm — which is a common design choice in action-RPG character armor, intended to create visual asymmetry and distinguish the character's silhouette. The Shardfall version features ash-textured plating with ember-glow accents; the Ironclad version features riveted steel plating with a pneumatic ram on the underside. The shared use of asymmetric shoulder armor is a genre convention, and the material rendering is substantially different. Despite the 35% similarity index, this asset falls within the "incidental overlap consistent with shared genre conventions" range.

Asset 12: Voidwalker Full Helm vs. Dreadnaught Visor — Similarity Index: 27%. Both are full-face helmets with narrow eye slits — a design category with inherently limited expressive range due to the functional requirements of concealing a humanoid face while providing visibility. The Shardfall version features a smooth, featureless faceplate with void-energy particle effects emanating from the eye slit; the Ironclad version features a bulkier, more industrial design with bolt-studded cheek guards and a perforated breath grille. The resemblance is driven by the constrained design space of full-face helmets.

Scènes à Faire Analysis for Character Armor. Medieval plate-armor silhouettes constitute the foundational visual vocabulary of the fantasy-RPG genre. The design elements shared between the Shardfall Chronicles and Ironclad Dominion armor sets — segmented plates, rounded pauldrons, articulated gauntlets, scale-mail patterns, full-face helmets, and asymmetric shoulder armor — are standard, stock elements that appear in virtually every fantasy RPG and in the broader tradition of fantasy art and illustration. Dr. Lautner's report catalogs the appearance of substantially similar armor design elements across dozens of commercially released titles, including but not limited to Dark Souls (2011), The Elder Scrolls V: Skyrim (2011), Monster Hunter: World (2018), Guild Wars 2 (2012), and Diablo III (2012), among many others. These elements are not the original creative expression of any single developer; they are the common visual language of the genre.

Under the scènes à faire doctrine, such stock elements are not protectable because they "flow naturally from the subject matter" and are "standard treatment" of the fantasy-RPG genre topic. Satava v. Lowry, 323 F.3d 805, 810 (9th Cir. 2003); Swirsky v. Carey, 376 F.3d 841, 850 (9th Cir. 2004). The Ninth Circuit has consistently held that elements "indispensable, or at least standard, in the treatment of a given topic" are not protectable. Cavalier v. Random House, Inc., 297 F.3d 815, 823 (9th Cir. 2002). The character armor similarities identified in this case fall squarely within this doctrine.

B. Environmental Crystal Textures (Assets 13–21)

Overview Table.

Summary: The environmental crystal texture category contains two assets that exceed the 40% threshold: Asset 15 (Aethervein Cavern Wall Texture vs. Forge Grotto Crystalline Wall) at 47%, and Asset 18 (Shardfall Spire Background Crystal vs. Resonance Pillar Environmental Prop) at 52%. Asset 18 registers the highest similarity index of any asset in this entire analysis. However, as discussed below, both above-threshold assets are subject to robust independent-creation evidence and scènes à faire defenses, and neither approaches the 70% threshold associated with a finding of copying. The remaining seven assets in this category range from 21% to 38%, with a category mean of approximately 32.0%.

Detailed Analysis of Each Asset (Assets 13–21). Asset 13: Crystalvein Cave Wall vs. Mineshaft Crystal Cluster — Similarity Index: 32%. Both assets depict clusters of elongated crystals protruding from a rocky cave wall surface. The Shardfall version uses a purple-hued color palette with soft ambient glow; the Ironclad version uses a desaturated mineral palette with pickaxe scarring on the surrounding rock surfaces, consistent with the game's mining and resource-extraction narrative. The crystal cluster motif is one of the most common environmental elements in fantasy game design, appearing in introductory tutorials for major game engines including Unity and Unreal Engine. The 32% similarity is attributable to the shared use of this stock environmental element.

Asset 14: Frostfire Geode Interior vs. Steam Vent Crystal Deposit — Similarity Index: 26%. Minimal resemblance beyond the generic concept of crystals visible within a rock cavity. Color palettes, crystal shapes, and lighting approaches differ substantially.

Asset 15: Aethervein Cavern Wall Texture vs. Forge Grotto Crystalline Wall — Similarity Index: 47% — EXCEEDS 40% THRESHOLD. This asset pair warrants detailed analysis. The Shardfall Chronicles "Aethervein Cavern" wall texture features elongated hexagonal crystal clusters embedded in a rough stone surface, with interior luminescence gradients creating a glowing, ethereal effect. The crystals radiate outward from multiple seed points, creating a pattern of overlapping growth clusters. The color palette is cool blue-violet, consistent with the game's dark-fantasy magical aesthetic.

The Ironclad Dominion "Forge Grotto" crystalline wall shares the general configuration of elongated hexagonal crystal clusters with interior luminescence gradients. This is the primary driver of the elevated similarity index. However, the Ironclad version introduces several significant differentiating elements: (i) industrial scarring on the crystal surfaces, including chisel marks and drill holes consistent with the game's resource-extraction narrative; (ii) soot deposits and particulate accumulation on the crystal facets, indicating proximity to the game's forge environments; (iii) embedded metal brackets and support struts integrated into the rock surface around the crystals, suggesting active mining infrastructure; and (iv) a fundamentally different color palette — amber-orange with warm-toned luminescence — compared to the Shardfall version's cool blue-violet tones.

Dr. Lautner's report addresses this asset pair at pages 42–48 and notes that the hexagonal crystal cluster pattern is a well-established procedural generation archetype. Hexagonal crystalline growth is the natural formation pattern for numerous real-world minerals, including quartz, beryl, and corundum. Game-engine procedural generation tools commonly produce hexagonal crystal formations as a default output. The color palettes differ significantly, and the CIELAB histogram intersection value is only 0.18 (on a 0–1 scale), indicating minimal color overlap.

Brindoval's metadata analysis confirms that the Forge Grotto textures were committed to the ironclad-main repository on April 22, 2020 — eleven months before Shardfall Chronicles was released. The commit includes not only the finished texture files but also the procedural generation parameters used to create them, demonstrating that the textures were generated using Redstone's proprietary crystal-generation tool rather than copied from any external source.

From a transformative-analysis perspective, the Ironclad version's industrial re-contextualization — transforming magical crystals into mined industrial resources — changes both the aesthetic meaning and the narrative function of the visual element. This is a textbook example of transformative use.

Asset 16: Shimmer Pool Crystal Bed vs. Cooling Vat Crystal Formation — Similarity Index: 21%. Low resemblance. Both depict crystals adjacent to a liquid surface, but the visual treatment, scale, and context differ substantially.

Asset 17: Deepstone Crystal Column vs. Ore-Pillar Crystal Strut — Similarity Index: 34%. Both are vertical crystal formations used as environmental props. The Shardfall version is a freestanding, luminous crystal pillar; the Ironclad version is a crystal formation encased in a metal structural framework, serving as a load-bearing element in the game's industrial environments. The shared element — a vertical crystal formation — is a standard environmental prop in fantasy games.

Asset 18: Shardfall Spire Background Crystal vs. Resonance Pillar Environmental Prop — Similarity Index: 52% — EXCEEDS 40% THRESHOLD. HIGHEST SIMILARITY INDEX ACROSS ALL 37 ASSETS. This asset pair is the most significant in the entire analysis and warrants the most detailed treatment.

The Shardfall Chronicles "Shardfall Spire" is a background crystal element visible in several of the game's outdoor environments. It features a tapered spire shape — a tall, narrow crystal that widens slightly at the base and tapers to a point at the apex — with internal fracture lines radiating outward from a central glow point. The fracture lines create a starburst pattern within the translucent crystal body, and the central glow point pulses slowly in-game, creating a bioluminescent effect. The color palette is cyan-white, consistent with the game's cool-toned magical aesthetic.

The Ironclad Dominion "Resonance Pillar" is an environmental prop that appears in several of the game's industrial zones. It shares the tapered spire shape with internal fracture lines radiating from a central glow point — the elements responsible for the elevated 52% similarity index. However, the Ironclad version differs in several critical respects:

(i) Scale: The Resonance Pillar is approximately twice the scale of the Shardfall Spire relative to the player character, creating a substantially different visual impact.

(ii) Mechanical Integration: The Resonance Pillar is integrated into a mechanical superstructure — gears, pistons, and pipe fittings are visible at the base of the pillar, and metal clamps encircle the crystal at multiple points along its height. The crystal is presented not as a natural formation but as a harvested energy source being exploited by the game's industrial society.

(iii) Color Map: The Resonance Pillar uses a green-gold color palette, in stark contrast to the Shardfall Spire's cyan-white tones. The CIELAB histogram intersection value is 0.12, indicating minimal color correspondence.

(iv) Surface Treatment: The Resonance Pillar's crystal surface features micro-cracks, surface abrasions, and embedded particulate matter consistent with industrial handling, whereas the Shardfall Spire has smooth, pristine crystal surfaces.

(v) Narrative Function: In Shardfall Chronicles, the Spire is a mysterious natural formation with unexplained magical significance. In Ironclad Dominion, the Resonance Pillar is explicitly identified in the game's lore as a power source mined from crystalline deposits and harnessed to fuel the game's mechanized infrastructure. The narrative context is fundamentally different.

Dr. Lautner's report attributes the core similarity to the "luminescent crystal spire" motif, which she documents as appearing in at least 15 prior fantasy games, including Final Fantasy XIV (2010/2013), World of Warcraft (2004), Guild Wars 2 (2012), Crystalis (1990), and The Legend of Zelda: Breath of the Wild (2017), among others. The tapered-spire-with-internal-glow motif is a standard trope of the fantasy genre, not a protectable creative expression unique to Shardfall Chronicles.

Brindoval's metadata analysis confirms that the Resonance Pillar concept art was committed to the ironclad-main repository on August 8, 2020 — seven months before Shardfall Chronicles was released. The commit includes a design specification document authored by Seo-Yeon Park that describes the Resonance Pillar's intended function as a "power-source environmental prop" and references industrial and steampunk design inspirations (specifically citing real-world Tesla coils and Victorian-era mining equipment). This contemporaneous design documentation further corroborates independent creation.

Even at 52%, this asset falls well below the 70% threshold typically indicative of copying. The independent-creation timeline is uncontroverted. The transformative reworking is substantial. And the core visual motif is a genre-standard trope. This asset does not support an inference of infringement.

Asset 19: Moonlit Cavern Ceiling Crystals vs. Reactor Chamber Ceiling Array — Similarity Index: 29%. Both depict crystals on a cave or chamber ceiling, but the Ironclad version features metal mounting brackets and wiring connecting the crystals to a reactor apparatus. Standard cave-ceiling crystal treatment.

Asset 20: Amethyst Grotto Lighting Texture vs. Furnace Chamber Ambient Glow — Similarity Index: 38%. This asset falls below the 40% threshold but is notable as the highest non-exceeding asset in this category. Both assets use amethyst-colored gradients in cave lighting to create atmospheric effects. The 38% similarity is attributable to the shared use of purple ambient lighting in underground environments, which is a procedural generation convention and a standard technique for creating atmospheric depth in cave environments. Dr. Lautner's report documents this lighting convention as appearing in game-engine tutorial materials and in the default environmental lighting presets of multiple commercial game engines.

Asset 21: Sunstone Floor Outcrop vs. Foundry Floor Crystal Seam — Similarity Index: 25%. Low resemblance. The Shardfall version depicts a glowing stone formation on a natural cave floor; the Ironclad version depicts crystals visible through cracks in an industrial foundry floor, surrounded by slag and metal debris.

Scènes à Faire Analysis for Crystal Textures. Crystalline cave environments are among the most ubiquitous visual settings in the fantasy-RPG genre. The visual elements that contribute to the similarity indices in this category — luminescent crystals, hexagonal formations, internal fracture patterns, color gradients suggesting magical energy, and crystal spires — are stock visual elements that have been documented in game design textbooks, tutorial materials, and commercially available asset libraries for decades. Dr. Lautner's report provides a comprehensive catalog of appearances of substantially similar crystal textures across 15+ titles predating both Shardfall Chronicles and Ironclad Dominion, demonstrating that these elements are part of the genre's shared visual vocabulary rather than the original creative expression of any single developer.

The hexagonal crystal formation pattern deserves particular mention. Hexagonal crystal growth is the natural formation pattern for numerous real-world mineral families and is the default output of most procedural crystal-generation algorithms. It is not a creative choice unique to Shardfall Chronicles; it is a reflection of natural mineralogy and standard procedural generation techniques.

Under the Ninth Circuit's application of the scènes à faire doctrine, elements that are "standard, stock, or common to a topic" are filtered out of the substantial-similarity analysis. Cavalier v. Random House, Inc., 297 F.3d at 823. The crystal texture elements at issue here are quintessential examples of such stock elements.

C. UI Icon Sets (Assets 22–29)

Overview Table.

Summary: The UI icon set category contains one asset that exceeds the 40% threshold: Asset 26 (Radial Ability Menu vs. Contextual Radial HUD) at 44%. The remaining seven assets range from 15% to 33%, with a category mean of approximately 26.8%. The UI category presents the strongest merger doctrine arguments in this case, as UI design in action-RPGs is heavily constrained by functional requirements, platform guidelines, and established player-usability conventions.

Detailed Analysis of Each Asset (Assets 22–29). Asset 22: Crystal Shard Inventory Grid vs. Ironworks Inventory Grid — Similarity Index: 23%. Both assets use a grid layout for inventory management — a near-universal convention in RPG games that dates to the earliest graphical RPGs. The Shardfall version uses crystal-themed border decoration; the Ironclad version uses riveted-metal border decoration. The grid layout itself is a functional design element driven by the need to display multiple item icons in an organized, scannable format. The 23% similarity reflects the shared grid structure, not protectable creative expression.

Asset 23: Rune-Circle Skill Icon vs. Gear-Stamp Skill Icon — Similarity Index: 15%. The lowest similarity index in the entire analysis. The two skill icons share only the basic concept of a circular border framing a skill symbol. The Shardfall version uses a magical rune-circle motif; the Ironclad version uses an industrial gear-stamp motif. There is no meaningful visual resemblance.

Asset 24: Mana/Health Orb Indicators vs. Pressure/Health Gauge Indicators — Similarity Index: 31%. Both assets display circular health and mana/resource indicators in the lower corners of the screen. Circular health and mana indicators are one of the most pervasive UI conventions in the RPG genre, with documented use dating to the late 1990s (e.g., Diablo, 1996; Diablo II, 2000). The Shardfall version uses liquid-filled crystal orbs; the Ironclad version uses industrial pressure gauges with needle indicators. The shared circular-indicator format is a functional UI convention, not protectable expression.

Asset 25: Quest Log Tab Icons vs. Mission Dossier Tab Icons — Similarity Index: 28%. Both use tabbed navigation icons for quest/mission tracking — a standard interface pattern across all RPGs. Minimal resemblance in the specific iconography.

Asset 26: Radial Ability Menu vs. Contextual Radial HUD — Similarity Index: 44% — EXCEEDS 40% THRESHOLD. This asset pair warrants detailed analysis, particularly because Dr. Yates's report assigns this pair a substantially higher similarity index of 78% (discussed in Section VII).

The Shardfall Chronicles radial ability menu is an 8-segment radial wheel with icon placeholders arranged around a circular perimeter and a central activation node. The player accesses the menu by holding a designated button, selects an ability by moving the cursor to the corresponding segment, and activates it by releasing the button. The segments are separated by thin divider lines, and each segment displays an ability icon and a cooldown indicator.

The Ironclad Dominion contextual radial HUD similarly employs an 8-segment radial wheel with icon placeholders and a central activation node. This structural similarity is the primary driver of the 44% similarity index. However, the Ironclad version differs from the Shardfall version in several significant respects:

(i) Visual Aesthetic: The Ironclad radial HUD uses gear-tooth dividers between segments (rather than simple lines), rivet accents at the junction points, and a translucent mechanical overlay aesthetic consistent with the game's steampunk visual language.

(ii) Dynamic Contextual Behavior: The Ironclad radial HUD dynamically reconfigures its segments based on the player's current context (combat, exploration, crafting, dialogue), displaying different sets of options depending on the game state. The Shardfall radial menu is a static ability-selection interface.

(iii) Segment Labeling System: The Ironclad version includes abbreviated text labels beneath each icon, along with key-binding indicators; the Shardfall version uses icons only.

(iv) Animation and Feedback: The Ironclad version features mechanical opening/closing animations (segments sliding into position like clockwork components) and haptic feedback integration for controller users, creating a fundamentally different user experience.

Dr. Lautner's report documents the radial menu as one of the most common UI paradigms in action-RPGs, appearing in dozens of titles across multiple decades. Notable prior implementations include Mass Effect (2007), Dragon Age: Origins (2009), The Secret World (2012), Guild Wars 2 (2012), and Final Fantasy XIV (2010/2013). The 8-segment radial wheel configuration is a standard implementation driven by usability research showing that 6–8 segments optimizes player selection speed and accuracy. The functional layout similarities between the two radial menus are driven by usability conventions and platform ergonomics, not by creative copying.

The radial HUD wireframe was committed to the ironclad-main repository on March 2, 2020 — over 12 months before Shardfall Chronicles' release. The commit message reads: "Initial radial HUD wireframe — 8-segment contextual layout per UX team spec (ref: design doc HUD-v2.3)." This commit, verified by Brindoval, confirms that the radial HUD design was conceived and documented well before any Redstone employee could have had access to Shardfall Chronicles.

From a legal perspective, the radial menu UI raises the strongest merger doctrine argument in this case. Where there are limited ways to express a functional concept — here, the concept of providing the player with quick access to 6–8 abilities during fast-paced gameplay via a radial selection interface — the idea and its expression merge, and the expression is not protectable. Ets-Hokin v. Skyy Spirits, Inc., 225 F.3d 1068, 1082 (9th Cir. 2000); Apple Computer, Inc. v. Kestrel Partners LLC, 35 F.3d 1435, 1444 (9th Cir. 1994). The 8-segment radial menu is a functional design choice dictated by usability constraints, not a creative expression protectable under copyright.

Asset 27: Character Stats Panel Border vs. Dossier Panel Frame — Similarity Index: 19%. Both use a rectangular frame to contain character statistics. The Shardfall version features a crystal-encrusted border; the Ironclad version features a riveted-metal frame. Minimal resemblance beyond the shared rectangular form, which is a universal UI convention.

Asset 28: Minimap Border / Compass Rose vs. Tactical Minimap Bezel — Similarity Index: 33%. Both assets feature a circular minimap with a decorative border and directional indicators. Circular minimaps are near-universal in RPGs and action-adventure games. The Shardfall version uses a magical-rune-inscribed border; the Ironclad version uses a brass-bezel border with mechanical compass needles. The 33% similarity reflects the shared circular-minimap convention and general border ornamentation, both of which are standard UI elements.

Asset 29: Dialogue box Frame vs. Comm-Link Dialogue Frame — Similarity Index: 21%. Both are rectangular frames used to display in-game dialogue text. The dialogue box is one of the most fundamental UI elements in any game with a narrative component, and its design is heavily constrained by functional requirements (text readability, character portrait display, response-option layout). The resemblance is de minimis.

Scènes à Faire / Merger Doctrine Analysis for UI Elements. UI elements in video games are heavily constrained by functional requirements, platform guidelines (including console manufacturer certification requirements for button prompts, text size, and accessibility), and established player-usability conventions developed over decades of genre evolution. The merger doctrine applies with particular force to UI design, where there are limited ways to express a functional concept such as inventory management (grid layout), health/resource display (circular indicators), ability selection (radial menu), or minimap navigation (circular map with directional indicators).

The Ninth Circuit has recognized that when "there are only a limited number of ways to express an idea," the idea and its expression merge, and the expression is not copyrightable. Ets-Hokin, 225 F.3d at 1082. In the context of software interfaces, the Ninth Circuit has further held that "[w]hen the idea and its expression are inseparable, copying the 'expression' will not be barred, since protecting the 'expression' in such circumstances would confer a monopoly of the 'idea' upon the copyright owner." Apple Computer, 35 F.3d at 1444.

The 8-segment radial menu is a functional design choice. The grid inventory layout is a functional design choice. The circular health/mana indicator is a functional design choice. These elements are not protectable creative expression, and their inclusion in both Shardfall Chronicles and Ironclad Dominion does not support an inference of copying.

D. Background Matte Paintings (Assets 30–37)

Overview Table.

Summary: No background matte painting pair exceeds the 40% threshold. The range is 20% to 39%, with a category mean of approximately 28.4%. Asset 32 (Shardfall Castle Twilight vs. Ironhold Castle at Dusk) is the closest to the threshold at 39%. This is the strongest category for Redstone's defense — the matte paintings consistently reflect the fundamentally different visual languages of the two games, and the compositional similarities are attributable entirely to genre-standard "fantasy vista" archetypes.

Detailed Analysis of Each Asset (Assets 30–37). Asset 30: Crystal Peak Vista vs. Iron Summit Panorama — Similarity Index: 34%. Both assets depict a fantasy mountain vista as seen from a high vantage point, with crystal formations visible among the peaks. The Shardfall version features a pristine, magical landscape with luminous crystal outcroppings and an ethereal sky; the Ironclad version features smokestacks, mining rigs, and cargo rail lines crisscrossing the mountainside, with a smog-hazed industrial sky. The shared element — a mountain vista with prominent geological features — is a quintessential fantasy landscape composition that has been used in innumerable fantasy works across all media. The 34% similarity reflects the shared compositional archetype, not protectable expression.

Asset 31: Enchanted Forest Canopy vs. Smog-Choked Timberland — Similarity Index: 20%. The lowest similarity index in the matte painting category. The Shardfall version depicts a magical forest with glowing foliage and fairy-light particles; the Ironclad version depicts a deforested industrial timberland with sawmills and pollution. There is no meaningful visual resemblance beyond the basic concept of "forest."

Asset 32: Shardfall Castle Twilight vs. Ironhold Castle at Dusk — Similarity Index: 39%. This asset pair registers the highest similarity index in the matte painting category and is the closest to the 40% threshold without exceeding it. Both depict a ruined castle silhouetted against a twilight sky, with a crystalline aurora visible in the upper portion of the composition. This compositional structure — a dark castle silhouette against a dramatic sky with atmospheric effects — is one of the most standard archetypes in fantasy art, traceable to the Romantic landscape paintings of Caspar David Friedrich and widely used in fantasy book covers, film posters, and game art.

Despite the shared compositional archetype, the Ironclad version features several elements absent from the Shardfall version: smokestacks rising from within the castle walls, airships visible in the middle distance, industrial infrastructure (cranes, scaffolding, cargo elevators) integrated into the castle architecture, and a warmer, soot-tinged color palette in the sky gradients. The Shardfall version's castle is a pristine medieval ruin with magical crystal growths; the Ironclad version's castle is an industrial-age military installation. The compositional similarity is a product of the shared "fantasy castle at twilight" genre convention, and the specific visual content is substantially different.

Asset 33: Abyssal Rift Panorama vs. Deepmine Chasm Overlook — Similarity Index: 27%. Both depict a deep chasm viewed from a cliff edge. The Shardfall version features a magical abyss with floating crystal formations; the Ironclad version features an industrial mining pit with elevator platforms and ore carts. Low resemblance beyond the shared chasm-overlook composition.

Asset 34: Moonrise Over Crystal Lake vs. Foundry District Moonrise — Similarity Index: 22%. Both depict a moonrise scene, but the Shardfall version features a tranquil crystal-studded lake, while the Ironclad version features an industrial district with cooling towers and slag heaps. The only shared element is the compositional placement of the moon, which is not protectable.

Asset 35: Glowmoss Cavern Interior vs. Biolume Mineshaft Interior — Similarity Index: 31%. Both depict underground cavern interiors with bioluminescent elements providing atmospheric lighting. The Shardfall version features natural bioluminescent moss and crystal formations; the Ironclad version features bioluminescent organisms in a mined-out tunnel with wooden support beams and abandoned rail tracks. Bioluminescent cave lighting is a common fantasy-game setting documented in

I. EXECUTIVE SUMMARY
This memorandum synthesizes the findings from Dr. Ingrid Lautner's expert report (served August 19, 2024) and Brindoval Forensic Consulting LLC's metadata verification analysis to assess the strength of Redstone Gaming Corp.'s ("Redstone") defense across all 37 visual assets challenged by Luminos Interactive LLC ("Luminos") in this action. We have conducted an asset-by-asset comparison analysis, cross-referencing Dr. Lautner's visual-comparison framework with the independent-creation evidence preserved in Redstone's version-control systems and the scènes à faire analysis applicable to each category of challenged content. This memo provides a comprehensive treatment of each asset category, identifies the four assets that warrant heightened attention, evaluates the fair use defense, critiques the opposing expert's methodology, and provides our recommendation regarding dispositive motion practice.
Bottom-Line Conclusion. Of the 37 assets Luminos challenges, only four (4) exceed a 40% similarity index — the recognized threshold of concern in visual-comparison analysis — and none exceeds 52%. The overwhelming majority of similarities between the challenged Ironclad Dominion assets and their purported Shardfall Chronicles counterparts are attributable to unprotectable genre conventions (scènes à faire), including standard fantasy-RPG visual tropes such as crystalline cave textures, medieval plate-armor silhouettes, radial menu interfaces, and fantasy landscape compositions. The independent-creation evidence drawn from the ironclad-main Git repository is robust and, as of the date of this memorandum, uncontroverted: all four above-threshold assets were committed to the repository months before Shardfall Chronicles was released or made publicly available.
Recommendation. Redstone should file a Motion for Summary Judgment on fair-use grounds, supplemented by independent creation and scènes à faire arguments. We recommend a target filing date of September 9, 2024, consistent with the case scheduling order and discovery completion. The motion should be accompanied by supporting declarations from Jordan Kessler (VP of Creative Development), Seo-Yeon Park (Lead Character Artist), Dr. Ingrid Lautner (expert), and Nathan Rourke (Brindoval Forensic Consulting LLC), together with a comprehensive Statement of Undisputed Material Facts. We further recommend filing a concurrent Daubert motion to exclude the testimony of Luminos's expert, Dr. Calvin Yates, whose report suffers from significant methodological deficiencies detailed in Section VII below.
Note Regarding Opposing Expert. Dr. Calvin Yates, retained by Luminos's counsel at Hargrove, Tanaka & Whitmore LLP, served his expert report on August 19, 2024. Dr. Yates reached contrary conclusions, opining that 14 of the 37 assets exceed 60% similarity. As discussed at length in Section VII, Dr. Yates's inflated similarity scores are attributable to a fundamentally flawed single-metric pixel-comparison methodology that fails to normalize for resolution, aspect ratio, or color space; fails to exclude unprotectable scènes à faire elements from the similarity calculation; and fails to account for the independent-creation timeline established by the ironclad-main repository. This memo identifies specific methodological deficiencies suitable for cross-examination and Daubert challenge.
II. BACKGROUND
A. The Underlying Works
Shardfall Chronicles. Shardfall Chronicles is an indie action-RPG developed by Luminos Interactive LLC, a Nevada limited liability company founded by Tobias Crane (Founder and Managing Member) and Elara Whitfield (Art Director and Co-Founder). The game was released on March 22, 2021, on PC (via the Steam digital distribution platform). Shardfall Chronicles features a dark-fantasy aesthetic characterized by crystalline environmental textures, stylized armored characters rendered in a painterly art style, and a distinctive radial menu user interface for ability selection and inventory management. The game received generally favorable reviews from independent gaming publications, with particular praise for its environmental art direction. Luminos registered the copyright in the game's visual assets with the United States Copyright Office on June 8, 2021 (Registration No. VA 2-254-781).
As of the date of this memorandum, Shardfall Chronicles has sold approximately 185,000 lifetime units at a manufacturer's suggested retail price ("MSRP") of $24.99, yielding estimated gross revenue of approximately $4.62 million. Luminos's FY 2023 revenue, as reflected in its financial statements prepared by Whitmore & Pine CPAs and produced in discovery, was approximately $2.1 million, a figure that includes both direct sales revenue and ancillary merchandise and licensing income. Luminos is a small independent studio with fewer than 20 full-time employees.
Ironclad Dominion. Ironclad Dominion is a AAA multiplayer tactical RPG developed by Redstone Gaming Corp., a Delaware corporation with its principal place of business in Henderson, Nevada. The game was created under the creative leadership of Jordan Kessler (Vice President of Creative Development) and Seo-Yeon Park (Lead Character Artist), among a team of approximately 340 artists, designers, programmers, and other development personnel. Ironclad Dominion was released on November 14, 2022, on PC (via Steam and Redstone's proprietary launcher), PlayStation 5, and Xbox Series X|S. The game features a mechanized-fantasy and steampunk visual environment — a thematic vocabulary fundamentally distinct from Shardfall Chronicles's dark-fantasy aesthetic. Ironclad Dominion's art direction is characterized by armored warrior characters with industrial and mechanical design elements, steampunk environmental assets, and a contextual radial HUD system.
Development of Ironclad Dominion commenced in Q1 2020. The first commit in the game's primary version-control repository ("ironclad-main") is dated February 12, 2020 — approximately thirteen (13) months before Shardfall Chronicles was released. The game generated $312 million in revenue in its first 12 months of commercial availability, making it one of the top-selling RPG titles of 2022–2023. Ironclad Dominion has been the subject of two post-launch expansion packs and an ongoing live-service content model.
B. Luminos's Claims
Luminos filed its Complaint in this action on March 18, 2024, in the United States District Court for the District of Nevada, Case No. 2:24-cv-00587-RWL, before the Honorable Rebecca W. Langford. The case was assigned to Judge Langford's docket following random assignment, and no reassignment has occurred.
Luminos alleges that 37 specific visual assets in Ironclad Dominion are "substantially similar" to corresponding assets in Shardfall Chronicles. The 37 challenged assets fall into four categories:
•  Character Armor Designs: 12 assets (Assets 1–12), comprising chest plates, pauldrons, gauntlets, helmets, greaves, and other components of in-game character armor sets.
•  Environmental Crystal Textures: 9 assets (Assets 13–21), comprising cave wall textures, crystal formation props, and crystalline environmental elements.
•  UI Icon Sets: 8 assets (Assets 22–29), comprising user interface elements such as inventory grids, health/mana indicators, radial ability menus, minimaps, and associated iconography.
•  Background Matte Paintings: 8 assets (Assets 30–37), comprising full-screen background illustrations used for loading screens, menu backgrounds, and distant environmental vistas.
Luminos's Complaint asserts claims for copyright infringement under 17 U.S.C. §§ 106 and 501. Luminos seeks actual damages of $28.5 million, calculated on an apportioned-profits theory: Luminos contends that 9.13% of Ironclad Dominion's $312 million first-year revenue is attributable to the allegedly infringing visual assets, yielding approximately $28.5 million ($312M × 9.13% ≈ $28.5M). The 9.13% apportionment figure was derived from a subjective assertion by Tobias Crane in his declaration filed in support of the Complaint, not from any consumer survey, conjoint analysis, or other empirically validated methodology. Luminos also seeks injunctive relief prohibiting Redstone from further distribution of Ironclad Dominion in its current form, statutory damages in the alternative under 17 U.S.C. § 504(c), and attorney's fees under 17 U.S.C. § 505.
C. Expert Engagement
Redstone's Expert — Dr. Ingrid Lautner. Dr. Ingrid Lautner was retained by Calderwood & Harkness LLP on behalf of Redstone pursuant to a retention letter dated May 28, 2024. Dr. Lautner is a Professor of Digital Media and Game Design at Pacific Western University, where she has taught since 2012. Her areas of specialty include visual asset comparison methodologies, procedural generation systems, and transformative design in interactive media. Dr. Lautner has published over 40 peer-reviewed articles in journals including the Journal of Digital Media Studies, the ACM Transactions on Graphics, and Computer Graphics Forum. She has been qualified as an expert witness in seven prior copyright actions involving digital visual content, including two in the District of Nevada. Dr. Lautner is compensated at a rate of $650 per hour for her work in this matter.
Dr. Lautner's expert report was completed and served on August 19, 2024, the expert-report deadline established by the Court's scheduling order. Her report encompasses a detailed visual-comparison analysis of all 37 challenged asset pairs, employing a multi-layer comparison methodology described in Section III below.
Brindoval Forensic Consulting LLC. Brindoval Forensic Consulting LLC was retained as a non-testifying consulting expert to perform metadata analysis and verification of Redstone's art pipeline and version-control logs. The lead consultant on the engagement is Nathan Rourke, a certified digital forensics examiner with over 15 years of experience in software repository analysis and metadata verification. Brindoval's offices are located at 3310 Wilshire Boulevard, Suite 700, Los Angeles, California 90010. Brindoval's work product has been incorporated into Dr. Lautner's expert report and may also serve as the basis for a separate declaration by Mr. Rourke in support of the anticipated Motion for Summary Judgment.
Luminos's Expert — Dr. Calvin Yates. Luminos's expert is Dr. Calvin Yates, an independent digital forensics consultant and former Associate Professor at Riverbend Institute of Technology (a position he held from 2015 to 2021). Dr. Yates specializes in pixel-level comparison of game textures and asset metadata forensics. He was retained by Hargrove, Tanaka & Whitmore LLP, Luminos's counsel of record (Daniel Hargrove, lead attorney; Megan Forsyth, associate). Dr. Yates's expert report was served on August 19, 2024, contemporaneously with Dr. Lautner's report. His report reaches conclusions sharply at odds with Dr. Lautner's findings, as discussed in detail in Section VII.
D. Evidentiary Foundation
The evidentiary foundation for the analysis set forth in this memorandum rests on several categories of evidence, all of which have been produced in discovery or obtained through depositions:
Version-Control Repository. Brindoval verified the integrity and timestamps of all 14,208 commits in the ironclad-main Git repository spanning from February 12, 2020, through October 2022. The verification process included hash-chain integrity analysis (confirming that SHA-1 commit hashes form an unbroken chain from the initial commit through the final pre-release commit), server-side log correlation (cross-referencing commit timestamps against Redstone's internal build server logs and backup timestamps), and author-attribution verification (confirming that commit authors correspond to known Redstone employees active during the relevant periods). Brindoval's analysis confirmed the integrity of the repository: there is no evidence of post-hoc tampering, backdating, or artificial insertion of commits.
Document Production. Redstone produced 42,316 pages of documents in this action (Bates Nos. RGC-000001 through RGC-042316), served on July 8, 2024. The production includes concept art archives for all character armor designs, environmental textures, UI elements, and matte paintings; internal design review presentations from the biweekly art review meetings conducted throughout Ironclad Dominion's development cycle; Git logs and commit messages; email correspondence among the art team; and licensing records for third-party assets and procedural generation tools.
Depositions. The following depositions of key witnesses have been completed:

III. METHODOLOGY — DR. LAUTNER'S VISUAL COMPARISON FRAMEWORK
A. Pixel-Level Similarity Index
Dr. Lautner employed a multi-layer comparison methodology that represents the current state of the art in digital visual asset comparison analysis. Her methodology integrates four distinct analytical layers, each capturing a different dimension of visual similarity:
1.  Normalized Structural Similarity (SSIM). Each asset pair was rendered at a standardized resolution (2048 × 2048 pixels for textures and matte paintings; native resolution for UI elements) and compared using the Structural Similarity Index Measure ("SSIM"), a perceptual metric that evaluates luminance, contrast, and structural information. Critically, Dr. Lautner normalized all renders for resolution and aspect ratio prior to comparison — a step that Dr. Yates omitted (see Section VII).
2.  Color Histogram Comparison. Dr. Lautner extracted color histograms in the CIELAB color space (a perceptually uniform color model) for each asset pair and computed histogram intersection values. This layer captures the degree of overlap in the color palettes used by the two assets, independent of their spatial arrangement.
3.  Edge-Detection Silhouette Overlay. Using Canny edge detection, Dr. Lautner generated silhouette maps for each asset and overlaid them to assess the degree of structural correspondence in the shapes and contours of the compared elements. This layer is particularly informative for character armor and environmental prop comparisons, where overall form and silhouette are key elements of visual identity.
4.  Feature-Point Matching. Dr. Lautner employed Scale-Invariant Feature Transform ("SIFT") feature-point detection and matching to identify and quantify the number of corresponding keypoints between asset pairs. Feature-point matching captures fine-grained details such as surface ornamentation, texturing patterns, and micro-structural similarities.
Each asset pair received a composite "similarity index" on a 0–100% scale, calculated as a weighted average of the four analytical layers (with weights calibrated to reflect the relative importance of each layer in the context of visual-art copyright comparison, as described in Dr. Lautner's report at pages 14–18). Dr. Lautner's calibration weights were developed through her prior academic research and have been published in peer-reviewed venues.
The similarity index should be interpreted according to the following ranges, which Dr. Lautner derived from empirical studies of known-copying and known-independent-creation data sets:
•  Below 30%: Negligible resemblance. Similarities at this level are consistent with coincidence, shared medium constraints, or the most basic elements of the genre.
•  30–40%: Incidental overlap consistent with shared genre conventions. Assets in this range may share general compositional features or thematic elements, but the degree of similarity does not, standing alone, support an inference of copying.
•  Above 40%: Warrants closer scrutiny. Assets exceeding this threshold require individualized analysis to determine whether the similarities are attributable to protectable creative expression or to unprotectable genre conventions, functional constraints, or independent creation.
•  Above 70%: Typically indicative of copying. Assets in this range exhibit a degree of correspondence that, absent an independent-creation defense, would support an inference that one work was derived from the other.
It bears emphasis that no asset in this matter approaches the 70% threshold. The highest similarity index recorded across all 37 asset pairs is 52% (Asset 18), which falls well below the range typically associated with a finding of copying.
Contrast with Dr. Yates's Methodology. Dr. Yates's methodology is discussed in detail in Section VII. At a summary level, the critical distinction is that Dr. Yates employed a single-metric pixel-comparison approach without normalization for resolution, aspect ratio, or color space, and without exclusion of unprotectable scènes à faire elements. These methodological failures systematically inflate Dr. Yates's similarity scores, producing results that are not reliable indicators of protectable-expression overlap.
B. Transformative-Use Evaluation
For each asset pair, Dr. Lautner additionally assessed whether the Ironclad Dominion version constitutes a transformative reworking of the visual concepts at issue. This assessment examined four dimensions of transformation:
•  Contextual Transformation: Whether the asset serves a different narrative or gameplay function in Ironclad Dominion than the corresponding asset serves in Shardfall Chronicles. For example, crystalline formations that serve as ambient environmental decoration in Shardfall Chronicles function as harvestable resources integrated into the gameplay economy of Ironclad Dominion.
•  Aesthetic Vocabulary Shift: Whether the asset has been reworked into Ironclad Dominion's mechanized-steampunk visual language, as distinct from Shardfall Chronicles's dark-fantasy aesthetic. This dimension captures the degree to which the challenged asset reflects the distinctive artistic identity of the accused work.
•  Narrative Function: Whether the asset carries different narrative meaning or communicates different themes in Ironclad Dominion — for instance, whether a crystal texture that symbolizes magical purity in Shardfall Chronicles has been reimagined as an industrial resource in Ironclad Dominion's steampunk world.
•  Compositional Structure: Whether the spatial arrangement, proportions, and visual hierarchy of the asset differ between the two works.
Dr. Lautner's transformative-use evaluation supports the conclusion that, across all four categories of challenged assets, Ironclad Dominion's visual content represents a fundamentally different artistic vision — one rooted in mechanized-industrial aesthetics — that repurposes generic fantasy motifs in a transformative manner.
C. Scènes à Faire Overlay
As a third analytical layer, Dr. Lautner identified which elements of visual similarity between the asset pairs are attributable to genre-standard tropes — that is, elements that are standard, stock, or common to the fantasy-RPG genre and are therefore unprotectable under the scènes à faire doctrine. For each asset pair, Dr. Lautner documented the specific elements that fall within the scènes à faire category and excluded those elements from her assessment of protectable-expression overlap.
Dr. Lautner's scènes à faire analysis draws on a comprehensive survey of commercially released fantasy-RPG titles spanning the period from 2000 to 2023. Her report identifies specific prior works exhibiting each of the challenged visual elements — crystalline cave formations, radial menu interfaces, medieval plate-armor silhouettes, and standard matte-painting compositions for fantasy landscapes — and documents the pervasiveness of these elements across the genre. This survey is detailed in Appendix C of Dr. Lautner's report and encompasses over 60 commercially released titles.
IV. ASSET-BY-ASSET COMPARISON RESULTS
This section presents the detailed asset-by-asset comparison results across all four categories of challenged visual elements. For each category, we provide an overview table summarizing the similarity indices, followed by individualized analysis of each asset pair, and concluding with a scènes à faire analysis applicable to the category as a whole.
A. Character Armor Designs (Assets 1–12)
Overview Table.  The following table summarizes the similarity index results for all 12 character armor design pairs. Each asset is identified by its Luminos exhibit designation and the corresponding Ironclad Dominion asset identifier.
Summary: All 12 character armor design pairs fall within a similarity index range of 18% to 41%. Only one asset — Asset 7 (Crystal Warden Helmet vs. Prism Knight Helm) — exceeds the 40% threshold, registering at 41%. Nine of the 12 assets fall below the 30% threshold, indicating negligible resemblance. The mean similarity index for the character armor category is 27.7%.
Detailed Analysis of Each Asset (Assets 1–12).  Asset 1: Obsidian Sentinel Chest Plate vs. Iron Vanguard Torso Armor — Similarity Index: 28%. The Shardfall Chronicles "Obsidian Sentinel" chest plate is a segmented plate-armor torso piece rendered in dark, matte-obsidian tones with subtle crystalline accents along the sternum. The Ironclad Dominion "Iron Vanguard" torso armor is likewise a segmented plate construction, but incorporates visible riveting along plate seams, interlocking gear motifs on the shoulder attachment points, and copper pipe accents running from the back plate to the collar guard, all consistent with Ironclad Dominion's steampunk aesthetic. The segmented plate construction shared by both assets is a ubiquitous design element in fantasy armor and is not protectable expression. Dr. Lautner's SSIM analysis shows significant structural divergence in the proportions and contours of the two pieces, and the color histogram comparison reflects entirely different palettes (obsidian-black/crystal-blue vs. burnished-iron/copper-orange). The first commit for Iron Vanguard art in the ironclad-main repository is dated March 15, 2020, predating Shardfall Chronicles' release by over one year. This asset presents no concern from a substantial-similarity perspective.
Asset 2: Frostguard Pauldrons vs. Steamwarden Pauldrons — Similarity Index: 22%. The resemblance between these two pauldron designs is minimal, limited to the generic rounded-dome shape common to virtually all fantasy shoulder armor. The Shardfall version features frost-etched detailing and crystalline inlays; the Ironclad version features exhaust vents and piston mechanisms. The 22% similarity is attributable entirely to the shared pauldron silhouette, a stock element of the genre.
Asset 3: Dragonscale Mail Shirt vs. Boilerplate Scale Vest — Similarity Index: 31%. Both assets employ a layered scale-mail texture — individual overlapping scales covering the torso. Dr. Lautner notes that scale-mail armor is one of the oldest and most commonly depicted armor types in fantasy media, appearing in historical illustrations dating to medieval manuscripts and in virtually every fantasy RPG released in the last two decades. The Shardfall version uses organic, reptilian-textured scales with iridescent shading; the Ironclad version uses stamped-metal scales with visible forge marks and industrial patina. The 31% similarity is driven by the shared scale-mail pattern, which is a genre-standard trope. The textural and material rendering differences are substantial.
Asset 4: Shadow Reaver Greaves vs. Piston-Leg Greaves — Similarity Index: 25%. Both are shin-guard armor pieces with articulated knee joints, a functional requirement for any character armor that must accommodate walking and running animations. The Ironclad version integrates hydraulic piston mechanisms at the knee, consistent with the game's mechanical-augmentation theme. The resemblance is driven by the anatomical constraints of leg armor design and does not reflect protectable creative expression.
Asset 5: Moonsilver Bracers vs. Copper Coil Bracers — Similarity Index: 19%. Minimal resemblance. The Shardfall bracers are slender, elegant forearm guards with lunar-glyph engravings; the Ironclad bracers are bulky, industrialized forearm pieces wrapped in copper coils and fitted with pressure gauges. The 19% similarity reflects only the shared functional form of a forearm armor piece.
Asset 6: Beast Warden Gauntlets vs. Mech-Claw Gauntlets — Similarity Index: 33%. Both gauntlet designs feature claw-like finger articulation — an elongated, tapered finger structure with segmented joints that evokes a predatory-animal aesthetic. This design element is a genre convention for the "beast knight" or "feral warrior" archetype, which appears in numerous prior fantasy RPGs. Despite the shared claw-like articulation, the Ironclad version employs pneumatic joint mechanisms, exposed wiring, and brass housings at each knuckle, fundamentally changing the visual character of the gauntlets from organic-bestial to mechanical-predatory. Dr. Lautner identified at least eight prior commercial RPG titles featuring gauntlets with substantially similar claw articulation, establishing that this element is a scènes à faire trope.
Asset 7: Crystal Warden Helmet vs. Prism Knight Helm — Similarity Index: 41% — EXCEEDS 40% THRESHOLD. This asset presents the closest similarity of any character armor pair and is one of only four assets across all 37 that exceeds the 40% threshold. The Shardfall Chronicles "Crystal Warden" helmet features a narrow visor slit flanked by angular crystalline projections extending upward from the brow line, giving the helmet a crown-like silhouette. The Ironclad Dominion "Prism Knight" helm shares the general configuration of a visor slit flanked by angular projections, which accounts for the elevated similarity index.
However, the Ironclad version introduces several significant design elements absent from the Shardfall helmet: (i) a mechanical retracting visor mechanism with visible hinge points and a locking lever on the right temple; (ii) brass-coil trim along the projections, replacing the smooth crystal surfaces of the Shardfall version; (iii) a darker, more muted color palette (gunmetal gray with amber accent lighting) compared to the Shardfall version's luminescent cyan-crystal finish; and (iv) industrial grommets and ventilation slits along the crown. Brindoval's metadata analysis confirms that the Prism Knight helm concept art was committed to the ironclad-main repository on June 4, 2020 — nine months before Shardfall Chronicles was released. This independent-creation evidence eliminates any inference of access-based copying.
From a transformative-analysis perspective, Dr. Lautner opines that the Prism Knight helm represents a mechanical and industrial reworking of the generic "crystal-adorned helmet" motif. The crystalline projections in the Ironclad version serve a different narrative purpose — they are described in the game's lore as prismatic energy conductors integrated into the warrior's powered armor suit, rather than magical crystalline growths. The aesthetic meaning of the helmet is fundamentally different: industrial utility rather than mystical ornamentation.
Even at 41%, this asset falls well below the 70% threshold typically indicative of copying. Combined with the independent-creation timeline and the transformative reworking, this asset does not support an inference of infringement.
Asset 8: Flameguard Boots vs. Forge-Tread Sabatons — Similarity Index: 24%. Both are armored foot pieces with reinforced toe caps — a standard element of any full plate-armor set. The Shardfall version features flame-motif engravings; the Ironclad version features treaded soles and exhaust ports. Minimal resemblance beyond the generic form factor.
Asset 9: Stonewall Cuirass vs. Ironhull Cuirass — Similarity Index: 18%. The lowest similarity index in the character armor category. The two assets share only the most basic cuirass shape. The Shardfall version is a naturalistic stone-textured breastplate; the Ironclad version is a riveted iron hull plate with ship-hull aesthetics. No meaningful resemblance.
Asset 10: Nightshade Cloak Armor vs. Smoke Shroud Plating — Similarity Index: 29%. Both assets combine a partial breastplate with draped fabric elements, creating a "cloaked warrior" silhouette. This combination is a well-established archetype in the fantasy-RPG genre (the rogue, assassin, or ranger class archetype). The fabric rendering, plate detailing, and color palettes are entirely distinct. The 29% similarity is attributable to the shared archetype.
Asset 11: Ashborn Shoulder Guard vs. Rivet-Plate Spaulder — Similarity Index: 35%. Both assets feature an asymmetric shoulder armor design — a single oversized shoulder plate worn on the dominant arm — which is a common design choice in action-RPG character armor, intended to create visual asymmetry and distinguish the character's silhouette. The Shardfall version features ash-textured plating with ember-glow accents; the Ironclad version features riveted steel plating with a pneumatic ram on the underside. The shared use of asymmetric shoulder armor is a genre convention, and the material rendering is substantially different. Despite the 35% similarity index, this asset falls within the "incidental overlap consistent with shared genre conventions" range.
Asset 12: Voidwalker Full Helm vs. Dreadnaught Visor — Similarity Index: 27%. Both are full-face helmets with narrow eye slits — a design category with inherently limited expressive range due to the functional requirements of concealing a humanoid face while providing visibility. The Shardfall version features a smooth, featureless faceplate with void-energy particle effects emanating from the eye slit; the Ironclad version features a bulkier, more industrial design with bolt-studded cheek guards and a perforated breath grille. The resemblance is driven by the constrained design space of full-face helmets.
Scènes à Faire Analysis for Character Armor.  Medieval plate-armor silhouettes constitute the foundational visual vocabulary of the fantasy-RPG genre. The design elements shared between the Shardfall Chronicles and Ironclad Dominion armor sets — segmented plates, rounded pauldrons, articulated gauntlets, scale-mail patterns, full-face helmets, and asymmetric shoulder armor — are standard, stock elements that appear in virtually every fantasy RPG and in the broader tradition of fantasy art and illustration. Dr. Lautner's report catalogs the appearance of substantially similar armor design elements across dozens of commercially released titles, including but not limited to Dark Souls (2011), The Elder Scrolls V: Skyrim (2011), Monster Hunter: World (2018), Guild Wars 2 (2012), and Diablo III (2012), among many others. These elements are not the original creative expression of any single developer; they are the common visual language of the genre.
Under the scènes à faire doctrine, such stock elements are not protectable because they "flow naturally from the subject matter" and are "standard treatment" of the fantasy-RPG genre topic. Satava v. Lowry, 323 F.3d 805, 810 (9th Cir. 2003); Swirsky v. Carey, 376 F.3d 841, 850 (9th Cir. 2004). The Ninth Circuit has consistently held that elements "indispensable, or at least standard, in the treatment of a given topic" are not protectable. Cavalier v. Random House, Inc., 297 F.3d 815, 823 (9th Cir. 2002). The character armor similarities identified in this case fall squarely within this doctrine.
B. Environmental Crystal Textures (Assets 13–21)
Overview Table.  
Summary: The environmental crystal texture category contains two assets that exceed the 40% threshold: Asset 15 (Aethervein Cavern Wall Texture vs. Forge Grotto Crystalline Wall) at 47%, and Asset 18 (Shardfall Spire Background Crystal vs. Resonance Pillar Environmental Prop) at 52%. Asset 18 registers the highest similarity index of any asset in this entire analysis. However, as discussed below, both above-threshold assets are subject to robust independent-creation evidence and scènes à faire defenses, and neither approaches the 70% threshold associated with a finding of copying. The remaining seven assets in this category range from 21% to 38%, with a category mean of approximately 32.0%.
Detailed Analysis of Each Asset (Assets 13–21).  Asset 13: Crystalvein Cave Wall vs. Mineshaft Crystal Cluster — Similarity Index: 32%. Both assets depict clusters of elongated crystals protruding from a rocky cave wall surface. The Shardfall version uses a purple-hued color palette with soft ambient glow; the Ironclad version uses a desaturated mineral palette with pickaxe scarring on the surrounding rock surfaces, consistent with the game's mining and resource-extraction narrative. The crystal cluster motif is one of the most common environmental elements in fantasy game design, appearing in introductory tutorials for major game engines including Unity and Unreal Engine. The 32% similarity is attributable to the shared use of this stock environmental element.
Asset 14: Frostfire Geode Interior vs. Steam Vent Crystal Deposit — Similarity Index: 26%. Minimal resemblance beyond the generic concept of crystals visible within a rock cavity. Color palettes, crystal shapes, and lighting approaches differ substantially.
Asset 15: Aethervein Cavern Wall Texture vs. Forge Grotto Crystalline Wall — Similarity Index: 47% — EXCEEDS 40% THRESHOLD. This asset pair warrants detailed analysis. The Shardfall Chronicles "Aethervein Cavern" wall texture features elongated hexagonal crystal clusters embedded in a rough stone surface, with interior luminescence gradients creating a glowing, ethereal effect. The crystals radiate outward from multiple seed points, creating a pattern of overlapping growth clusters. The color palette is cool blue-violet, consistent with the game's dark-fantasy magical aesthetic.
The Ironclad Dominion "Forge Grotto" crystalline wall shares the general configuration of elongated hexagonal crystal clusters with interior luminescence gradients. This is the primary driver of the elevated similarity index. However, the Ironclad version introduces several significant differentiating elements: (i) industrial scarring on the crystal surfaces, including chisel marks and drill holes consistent with the game's resource-extraction narrative; (ii) soot deposits and particulate accumulation on the crystal facets, indicating proximity to the game's forge environments; (iii) embedded metal brackets and support struts integrated into the rock surface around the crystals, suggesting active mining infrastructure; and (iv) a fundamentally different color palette — amber-orange with warm-toned luminescence — compared to the Shardfall version's cool blue-violet tones.
Dr. Lautner's report addresses this asset pair at pages 42–48 and notes that the hexagonal crystal cluster pattern is a well-established procedural generation archetype. Hexagonal crystalline growth is the natural formation pattern for numerous real-world minerals, including quartz, beryl, and corundum. Game-engine procedural generation tools commonly produce hexagonal crystal formations as a default output. The color palettes differ significantly, and the CIELAB histogram intersection value is only 0.18 (on a 0–1 scale), indicating minimal color overlap.
Brindoval's metadata analysis confirms that the Forge Grotto textures were committed to the ironclad-main repository on April 22, 2020 — eleven months before Shardfall Chronicles was released. The commit includes not only the finished texture files but also the procedural generation parameters used to create them, demonstrating that the textures were generated using Redstone's proprietary crystal-generation tool rather than copied from any external source.
From a transformative-analysis perspective, the Ironclad version's industrial re-contextualization — transforming magical crystals into mined industrial resources — changes both the aesthetic meaning and the narrative function of the visual element. This is a textbook example of transformative use.
Asset 16: Shimmer Pool Crystal Bed vs. Cooling Vat Crystal Formation — Similarity Index: 21%. Low resemblance. Both depict crystals adjacent to a liquid surface, but the visual treatment, scale, and context differ substantially.
Asset 17: Deepstone Crystal Column vs. Ore-Pillar Crystal Strut — Similarity Index: 34%. Both are vertical crystal formations used as environmental props. The Shardfall version is a freestanding, luminous crystal pillar; the Ironclad version is a crystal formation encased in a metal structural framework, serving as a load-bearing element in the game's industrial environments. The shared element — a vertical crystal formation — is a standard environmental prop in fantasy games.
Asset 18: Shardfall Spire Background Crystal vs. Resonance Pillar Environmental Prop — Similarity Index: 52% — EXCEEDS 40% THRESHOLD. HIGHEST SIMILARITY INDEX ACROSS ALL 37 ASSETS. This asset pair is the most significant in the entire analysis and warrants the most detailed treatment.
The Shardfall Chronicles "Shardfall Spire" is a background crystal element visible in several of the game's outdoor environments. It features a tapered spire shape — a tall, narrow crystal that widens slightly at the base and tapers to a point at the apex — with internal fracture lines radiating outward from a central glow point. The fracture lines create a starburst pattern within the translucent crystal body, and the central glow point pulses slowly in-game, creating a bioluminescent effect. The color palette is cyan-white, consistent with the game's cool-toned magical aesthetic.
The Ironclad Dominion "Resonance Pillar" is an environmental prop that appears in several of the game's industrial zones. It shares the tapered spire shape with internal fracture lines radiating from a central glow point — the elements responsible for the elevated 52% similarity index. However, the Ironclad version differs in several critical respects:
(i) Scale: The Resonance Pillar is approximately twice the scale of the Shardfall Spire relative to the player character, creating a substantially different visual impact.
(ii) Mechanical Integration: The Resonance Pillar is integrated into a mechanical superstructure — gears, pistons, and pipe fittings are visible at the base of the pillar, and metal clamps encircle the crystal at multiple points along its height. The crystal is presented not as a natural formation but as a harvested energy source being exploited by the game's industrial society.
(iii) Color Map: The Resonance Pillar uses a green-gold color palette, in stark contrast to the Shardfall Spire's cyan-white tones. The CIELAB histogram intersection value is 0.12, indicating minimal color correspondence.
(iv) Surface Treatment: The Resonance Pillar's crystal surface features micro-cracks, surface abrasions, and embedded particulate matter consistent with industrial handling, whereas the Shardfall Spire has smooth, pristine crystal surfaces.
(v) Narrative Function: In Shardfall Chronicles, the Spire is a mysterious natural formation with unexplained magical significance. In Ironclad Dominion, the Resonance Pillar is explicitly identified in the game's lore as a power source mined from crystalline deposits and harnessed to fuel the game's mechanized infrastructure. The narrative context is fundamentally different.
Dr. Lautner's report attributes the core similarity to the "luminescent crystal spire" motif, which she documents as appearing in at least 15 prior fantasy games, including Final Fantasy XIV (2010/2013), World of Warcraft (2004), Guild Wars 2 (2012), Crystalis (1990), and The Legend of Zelda: Breath of the Wild (2017), among others. The tapered-spire-with-internal-glow motif is a standard trope of the fantasy genre, not a protectable creative expression unique to Shardfall Chronicles.
Brindoval's metadata analysis confirms that the Resonance Pillar concept art was committed to the ironclad-main repository on August 8, 2020 — seven months before Shardfall Chronicles was released. The commit includes a design specification document authored by Seo-Yeon Park that describes the Resonance Pillar's intended function as a "power-source environmental prop" and references industrial and steampunk design inspirations (specifically citing real-world Tesla coils and Victorian-era mining equipment). This contemporaneous design documentation further corroborates independent creation.
Even at 52%, this asset falls well below the 70% threshold typically indicative of copying. The independent-creation timeline is uncontroverted. The transformative reworking is substantial. And the core visual motif is a genre-standard trope. This asset does not support an inference of infringement.
Asset 19: Moonlit Cavern Ceiling Crystals vs. Reactor Chamber Ceiling Array — Similarity Index: 29%. Both depict crystals on a cave or chamber ceiling, but the Ironclad version features metal mounting brackets and wiring connecting the crystals to a reactor apparatus. Standard cave-ceiling crystal treatment.
Asset 20: Amethyst Grotto Lighting Texture vs. Furnace Chamber Ambient Glow — Similarity Index: 38%. This asset falls below the 40% threshold but is notable as the highest non-exceeding asset in this category. Both assets use amethyst-colored gradients in cave lighting to create atmospheric effects. The 38% similarity is attributable to the shared use of purple ambient lighting in underground environments, which is a procedural generation convention and a standard technique for creating atmospheric depth in cave environments. Dr. Lautner's report documents this lighting convention as appearing in game-engine tutorial materials and in the default environmental lighting presets of multiple commercial game engines.
Asset 21: Sunstone Floor Outcrop vs. Foundry Floor Crystal Seam — Similarity Index: 25%. Low resemblance. The Shardfall version depicts a glowing stone formation on a natural cave floor; the Ironclad version depicts crystals visible through cracks in an industrial foundry floor, surrounded by slag and metal debris.
Scènes à Faire Analysis for Crystal Textures.  Crystalline cave environments are among the most ubiquitous visual settings in the fantasy-RPG genre. The visual elements that contribute to the similarity indices in this category — luminescent crystals, hexagonal formations, internal fracture patterns, color gradients suggesting magical energy, and crystal spires — are stock visual elements that have been documented in game design textbooks, tutorial materials, and commercially available asset libraries for decades. Dr. Lautner's report provides a comprehensive catalog of appearances of substantially similar crystal textures across 15+ titles predating both Shardfall Chronicles and Ironclad Dominion, demonstrating that these elements are part of the genre's shared visual vocabulary rather than the original creative expression of any single developer.
The hexagonal crystal formation pattern deserves particular mention. Hexagonal crystal growth is the natural formation pattern for numerous real-world mineral families and is the default output of most procedural crystal-generation algorithms. It is not a creative choice unique to Shardfall Chronicles; it is a reflection of natural mineralogy and standard procedural generation techniques.
Under the Ninth Circuit's application of the scènes à faire doctrine, elements that are "standard, stock, or common to a topic" are filtered out of the substantial-similarity analysis. Cavalier v. Random House, Inc., 297 F.3d at 823. The crystal texture elements at issue here are quintessential examples of such stock elements.
C. UI Icon Sets (Assets 22–29)
Overview Table.  
Summary: The UI icon set category contains one asset that exceeds the 40% threshold: Asset 26 (Radial Ability Menu vs. Contextual Radial HUD) at 44%. The remaining seven assets range from 15% to 33%, with a category mean of approximately 26.8%. The UI category presents the strongest merger doctrine arguments in this case, as UI design in action-RPGs is heavily constrained by functional requirements, platform guidelines, and established player-usability conventions.
Detailed Analysis of Each Asset (Assets 22–29).  Asset 22: Crystal Shard Inventory Grid vs. Ironworks Inventory Grid — Similarity Index: 23%. Both assets use a grid layout for inventory management — a near-universal convention in RPG games that dates to the earliest graphical RPGs. The Shardfall version uses crystal-themed border decoration; the Ironclad version uses riveted-metal border decoration. The grid layout itself is a functional design element driven by the need to display multiple item icons in an organized, scannable format. The 23% similarity reflects the shared grid structure, not protectable creative expression.
Asset 23: Rune-Circle Skill Icon vs. Gear-Stamp Skill Icon — Similarity Index: 15%. The lowest similarity index in the entire analysis. The two skill icons share only the basic concept of a circular border framing a skill symbol. The Shardfall version uses a magical rune-circle motif; the Ironclad version uses an industrial gear-stamp motif. There is no meaningful visual resemblance.
Asset 24: Mana/Health Orb Indicators vs. Pressure/Health Gauge Indicators — Similarity Index: 31%. Both assets display circular health and mana/resource indicators in the lower corners of the screen. Circular health and mana indicators are one of the most pervasive UI conventions in the RPG genre, with documented use dating to the late 1990s (e.g., Diablo, 1996; Diablo II, 2000). The Shardfall version uses liquid-filled crystal orbs; the Ironclad version uses industrial pressure gauges with needle indicators. The shared circular-indicator format is a functional UI convention, not protectable expression.
Asset 25: Quest Log Tab Icons vs. Mission Dossier Tab Icons — Similarity Index: 28%. Both use tabbed navigation icons for quest/mission tracking — a standard interface pattern across all RPGs. Minimal resemblance in the specific iconography.
Asset 26: Radial Ability Menu vs. Contextual Radial HUD — Similarity Index: 44% — EXCEEDS 40% THRESHOLD. This asset pair warrants detailed analysis, particularly because Dr. Yates's report assigns this pair a substantially higher similarity index of 78% (discussed in Section VII).
The Shardfall Chronicles radial ability menu is an 8-segment radial wheel with icon placeholders arranged around a circular perimeter and a central activation node. The player accesses the menu by holding a designated button, selects an ability by moving the cursor to the corresponding segment, and activates it by releasing the button. The segments are separated by thin divider lines, and each segment displays an ability icon and a cooldown indicator.
The Ironclad Dominion contextual radial HUD similarly employs an 8-segment radial wheel with icon placeholders and a central activation node. This structural similarity is the primary driver of the 44% similarity index. However, the Ironclad version differs from the Shardfall version in several significant respects:
(i) Visual Aesthetic: The Ironclad radial HUD uses gear-tooth dividers between segments (rather than simple lines), rivet accents at the junction points, and a translucent mechanical overlay aesthetic consistent with the game's steampunk visual language.
(ii) Dynamic Contextual Behavior: The Ironclad radial HUD dynamically reconfigures its segments based on the player's current context (combat, exploration, crafting, dialogue), displaying different sets of options depending on the game state. The Shardfall radial menu is a static ability-selection interface.
(iii) Segment Labeling System: The Ironclad version includes abbreviated text labels beneath each icon, along with key-binding indicators; the Shardfall version uses icons only.
(iv) Animation and Feedback: The Ironclad version features mechanical opening/closing animations (segments sliding into position like clockwork components) and haptic feedback integration for controller users, creating a fundamentally different user experience.
Dr. Lautner's report documents the radial menu as one of the most common UI paradigms in action-RPGs, appearing in dozens of titles across multiple decades. Notable prior implementations include Mass Effect (2007), Dragon Age: Origins (2009), The Secret World (2012), Guild Wars 2 (2012), and Final Fantasy XIV (2010/2013). The 8-segment radial wheel configuration is a standard implementation driven by usability research showing that 6–8 segments optimizes player selection speed and accuracy. The functional layout similarities between the two radial menus are driven by usability conventions and platform ergonomics, not by creative copying.
The radial HUD wireframe was committed to the ironclad-main repository on March 2, 2020 — over 12 months before Shardfall Chronicles' release. The commit message reads: "Initial radial HUD wireframe — 8-segment contextual layout per UX team spec (ref: design doc HUD-v2.3)." This commit, verified by Brindoval, confirms that the radial HUD design was conceived and documented well before any Redstone employee could have had access to Shardfall Chronicles.
From a legal perspective, the radial menu UI raises the strongest merger doctrine argument in this case. Where there are limited ways to express a functional concept — here, the concept of providing the player with quick access to 6–8 abilities during fast-paced gameplay via a radial selection interface — the idea and its expression merge, and the expression is not protectable. Ets-Hokin v. Skyy Spirits, Inc., 225 F.3d 1068, 1082 (9th Cir. 2000); Apple Computer, Inc. v. Kestrel Partners LLC, 35 F.3d 1435, 1444 (9th Cir. 1994). The 8-segment radial menu is a functional design choice dictated by usability constraints, not a creative expression protectable under copyright.
Asset 27: Character Stats Panel Border vs. Dossier Panel Frame — Similarity Index: 19%. Both use a rectangular frame to contain character statistics. The Shardfall version features a crystal-encrusted border; the Ironclad version features a riveted-metal frame. Minimal resemblance beyond the shared rectangular form, which is a universal UI convention.
Asset 28: Minimap Border / Compass Rose vs. Tactical Minimap Bezel — Similarity Index: 33%. Both assets feature a circular minimap with a decorative border and directional indicators. Circular minimaps are near-universal in RPGs and action-adventure games. The Shardfall version uses a magical-rune-inscribed border; the Ironclad version uses a brass-bezel border with mechanical compass needles. The 33% similarity reflects the shared circular-minimap convention and general border ornamentation, both of which are standard UI elements.
Asset 29: Dialogue box Frame vs. Comm-Link Dialogue Frame — Similarity Index: 21%. Both are rectangular frames used to display in-game dialogue text. The dialogue box is one of the most fundamental UI elements in any game with a narrative component, and its design is heavily constrained by functional requirements (text readability, character portrait display, response-option layout). The resemblance is de minimis.
Scènes à Faire / Merger Doctrine Analysis for UI Elements.  UI elements in video games are heavily constrained by functional requirements, platform guidelines (including console manufacturer certification requirements for button prompts, text size, and accessibility), and established player-usability conventions developed over decades of genre evolution. The merger doctrine applies with particular force to UI design, where there are limited ways to express a functional concept such as inventory management (grid layout), health/resource display (circular indicators), ability selection (radial menu), or minimap navigation (circular map with directional indicators).
The Ninth Circuit has recognized that when "there are only a limited number of ways to express an idea," the idea and its expression merge, and the expression is not copyrightable. Ets-Hokin, 225 F.3d at 1082. In the context of software interfaces, the Ninth Circuit has further held that "[w]hen the idea and its expression are inseparable, copying the 'expression' will not be barred, since protecting the 'expression' in such circumstances would confer a monopoly of the 'idea' upon the copyright owner." Apple Computer, 35 F.3d at 1444.
The 8-segment radial menu is a functional design choice. The grid inventory layout is a functional design choice. The circular health/mana indicator is a functional design choice. These elements are not protectable creative expression, and their inclusion in both Shardfall Chronicles and Ironclad Dominion does not support an inference of copying.
D. Background Matte Paintings (Assets 30–37)
Overview Table.  
Summary: No background matte painting pair exceeds the 40% threshold. The range is 20% to 39%, with a category mean of approximately 28.4%. Asset 32 (Shardfall Castle Twilight vs. Ironhold Castle at Dusk) is the closest to the threshold at 39%. This is the strongest category for Redstone's defense — the matte paintings consistently reflect the fundamentally different visual languages of the two games, and the compositional similarities are attributable entirely to genre-standard "fantasy vista" archetypes.
Detailed Analysis of Each Asset (Assets 30–37).  Asset 30: Crystal Peak Vista vs. Iron Summit Panorama — Similarity Index: 34%. Both assets depict a fantasy mountain vista as seen from a high vantage point, with crystal formations visible among the peaks. The Shardfall version features a pristine, magical landscape with luminous crystal outcroppings and an ethereal sky; the Ironclad version features smokestacks, mining rigs, and cargo rail lines crisscrossing the mountainside, with a smog-hazed industrial sky. The shared element — a mountain vista with prominent geological features — is a quintessential fantasy landscape composition that has been used in innumerable fantasy works across all media. The 34% similarity reflects the shared compositional archetype, not protectable expression.
Asset 31: Enchanted Forest Canopy vs. Smog-Choked Timberland — Similarity Index: 20%. The lowest similarity index in the matte painting category. The Shardfall version depicts a magical forest with glowing foliage and fairy-light particles; the Ironclad version depicts a deforested industrial timberland with sawmills and pollution. There is no meaningful visual resemblance beyond the basic concept of "forest."
Asset 32: Shardfall Castle Twilight vs. Ironhold Castle at Dusk — Similarity Index: 39%. This asset pair registers the highest similarity index in the matte painting category and is the closest to the 40% threshold without exceeding it. Both depict a ruined castle silhouetted against a twilight sky, with a crystalline aurora visible in the upper portion of the composition. This compositional structure — a dark castle silhouette against a dramatic sky with atmospheric effects — is one of the most standard archetypes in fantasy art, traceable to the Romantic landscape paintings of Caspar David Friedrich and widely used in fantasy book covers, film posters, and game art.
Despite the shared compositional archetype, the Ironclad version features several elements absent from the Shardfall version: smokestacks rising from within the castle walls, airships visible in the middle distance, industrial infrastructure (cranes, scaffolding, cargo elevators) integrated into the castle architecture, and a warmer, soot-tinged color palette in the sky gradients. The Shardfall version's castle is a pristine medieval ruin with magical crystal growths; the Ironclad version's castle is an industrial-age military installation. The compositional similarity is a product of the shared "fantasy castle at twilight" genre convention, and the specific visual content is substantially different.
Asset 33: Abyssal Rift Panorama vs. Deepmine Chasm Overlook — Similarity Index: 27%. Both depict a deep chasm viewed from a cliff edge. The Shardfall version features a magical abyss with floating crystal formations; the Ironclad version features an industrial mining pit with elevator platforms and ore carts. Low resemblance beyond the shared chasm-overlook composition.
Asset 34: Moonrise Over Crystal Lake vs. Foundry District Moonrise — Similarity Index: 22%. Both depict a moonrise scene, but the Shardfall version features a tranquil crystal-studded lake, while the Ironclad version features an industrial district with cooling towers and slag heaps. The only shared element is the compositional placement of the moon, which is not protectable.
Asset 35: Glowmoss Cavern Interior vs. Biolume Mineshaft Interior — Similarity Index: 31%. Both depict underground cavern interiors with bioluminescent elements providing atmospheric lighting. The Shardfall version features natural bioluminescent moss and crystal formations; the Ironclad version features bioluminescent organisms in a mined-out tunnel with wooden support beams and abandoned rail tracks. Bioluminescent cave lighting is a common fantasy-game setting documented in
