I. Executive Summary This memorandum summarizes the findings from the preliminary patent landscape and freedom-to-operate ("FTO") analysis conducted by Crestline Patent Analytics LLC ("Crestline"), the final report of which was delivered to Calderwood & Harkness LLP on July 10, 2023. The purpose of this memorandum is to distill Crestline's findings, provide our independent assessment of the associated legal risks, an

II. Engagement Background Retention of Crestline Patent Analytics LLC On June 26, 2023, Calderwood & Harkness LLP, acting on behalf of and at the direction of Brightfield, retained Crestline Patent Analytics LLC ("Crestline"), located at 2301 Wilson Boulevard, Suite 710, Arlington, VA 22201, to conduct a patent landscape assessment and preliminary FTO analysis of the DeltaSync intellectual property portfolio. The eng

III. Overview of the DeltaSync Patent Portfolio A. Issued U.S. Utility Patents Nexilis currently holds fourteen (14) issued U.S. utility patents, numbered U.S. Patent Nos. 11,234,567 through 11,234,580 (collectively, the "DeltaSync Patents"). These patents collectively cover the core technology underlying the DeltaSync Platform, which relates to distributed-cache orchestration enabling sub-millisecond data synchroniz

IV. Freedom-to-Operate Analysis A. Scope of Analysis The FTO analysis conducted by Crestline was designed to assess whether Brightfield's specific proposed use case — the integration of DeltaSync technology into the Stratos enterprise cloud-management platform for deployment to enterprise customers across multiple industry verticals — would risk infringing any third-party patent rights. The FTO analysis is distinct f

1. API-Level Integration Methods. One patent family contains claims directed to methods for integrating cache orchestration systems with cloud management platforms at the API level, including specific claim elements related to the use of RESTful API endpoints for cache node provisioning and configuration. Depending on the specific architecture of the Stratos-DeltaSync integration, certain claims in this family could

2. Data-Routing Optimizations in Multi-Tenant SaaS Environments. A second patent family contains claims directed to data-routing optimization techniques specifically applicable to multi-tenant SaaS environments, where cache data is partitioned and routed based on tenant-specific policies and quality-of-service parameters. Because the Stratos platform is a multi-tenant SaaS offering and the DeltaSync integration would

3. Distributed Lock Management Techniques. A third patent family contains claims directed to distributed lock management techniques used in conjunction with cache synchronization, specifically addressing the use of lease-based locks to manage concurrent write access to cache objects across distributed nodes. Distributed lock management is a fundamental component of any distributed-cache system, and the DeltaSync Plat

V. Key Observations and Risk Factors A. Ownership and Encumbrances All fourteen issued DeltaSync Patents and six Pending Applications appear to be solely owned by Nexilis Innovations Ltd. based on recorded assignment documents in the USPTO assignment records. Our preliminary review identified no co-owners, co-assignees, or any recorded security interests, liens, or pledges against any of the DeltaSync intellectual pr

VI. Recommended Next Steps Based on our review of the Crestline report and the analysis set forth in this memorandum, we recommend the following next steps:

1. Detailed Claim Charting. We recommend engaging Crestline to perform detailed claim charting of the three high-priority third-party patent families identified in Section IV.B against the specific Stratos platform architecture. This analysis will require Crestline to have access to Brightfield's technical specifications and system architecture documentation for the planned DeltaSync-Stratos integration. We anticipat

2. Full Prosecution History Review. We recommend completing a comprehensive analysis of the prosecution histories for all fourteen issued DeltaSync Patents. This review should focus particularly on the two Cluster 2 patents flagged by Crestline for potential obviousness vulnerability, as well as on any narrowing amendments, examiner interviews, or statements made during prosecution that could limit claim scope under

3. Pending Application Analysis. We recommend obtaining and analyzing the full prosecution files for the six Pending Applications (App. Nos. 17/901,201 through 17/901,206), including any outstanding office actions, examiner's search reports, and applicant responses filed to date. This analysis will allow us to assess the likelihood that the Pending Applications will mature into issued patents and to evaluate the expe

4. Security Interest and Encumbrance Diligence. We recommend conducting UCC lien searches in the State of Delaware and the Commonwealth of Massachusetts to determine whether any security interests have been filed against Nexilis's intellectual property assets. In addition, to the extent feasible under the mutual NDA dated June 19, 2023, we recommend requesting and reviewing Nexilis's Series B financing documents to i

5. Inventor Assignment Verification. We recommend requesting copies of all inventor assignment agreements for the named inventors on the DeltaSync Patents and Pending Applications, including any agreements between Nexilis and its co-founders, Dr. Samira Hajjar and Dr. Eoin Callahan, as well as any agreements between the co-founders and MIT relating to intellectual property developed during their academic tenure. Thes

6. License Agreement IP Provisions. Based on the findings of the ongoing diligence, we recommend ensuring that the Technology License Agreement includes the following key intellectual property provisions: (a) Comprehensive Representations and Warranties regarding Nexilis's sole ownership of the DeltaSync intellectual property and the non-infringement of third-party patent rights; (b) Robust IP Indemnification Provisi

7. International Patent Landscape. If Brightfield's Stratos platform deployment extends to non-U.S. markets in a material way — including the European Union, the United Kingdom, Japan, or other significant technology markets — we recommend expanding the FTO analysis to cover key international jurisdictions. This would include identifying relevant third-party patents in those jurisdictions and assessing whether Nexili

VII. Crestline Engagement Fee The total disbursement for Crestline Patent Analytics LLC's preliminary engagement is $42,500. This amount covers the patent landscape assessment, preliminary FTO screening, and preparation of the preliminary patent landscape memorandum delivered on July 10, 2023. The disbursement has been invoiced to Matter No. 1042-00003 under Billing Code BCS-NEXILIS-LIC-2023 and will appear on Bright

VIII. Conclusion The DeltaSync patent portfolio represents a substantive and cohesive body of intellectual property covering key distributed-cache orchestration technologies. The portfolio, which comprises fourteen issued U.S. utility patents and six pending applications, addresses core innovations across cache coherence protocols, orchestration layer architecture, low-latency data synchronization, and security and a
