I. PURPOSE AND SCOPE OF THIS MEMORANDUM This memorandum provides the preliminary damages framework for Dr. Lawrence Kessler's use in developing his expert report and opinions on patent damages in Optiwave Semiconductor Corp. v. Lumos Photonics, Inc., Case No. 5:22-cv-03417-EJD (N.D. Cal.). It is intended to serve as an orienting document that identifies and synthesizes the key facts, revenue data, patent portfolio co

II. CASE BACKGROUND AND PROCEDURAL POSTURE A. The Parties

1. Plaintiff — Optiwave Semiconductor Corp. (OWS). Optiwave Semiconductor Corp. ("OWS" or "Optiwave") is a Delaware corporation headquartered at 2775 Augustine Drive, Suite 400, San Jose, California 95054. OWS is a fabless semiconductor design company specializing in the design and commercialization of silicon photonics integrated circuits for data center interconnects and telecommunications applications. Founded in

2. Defendant — Lumos Photonics, Inc. (Lumos). Lumos Photonics, Inc. ("Lumos") is a Delaware corporation headquartered at 9400 McNeil Drive, Building 7, Austin, Texas 78758. Unlike OWS, Lumos operates as an integrated device manufacturer ("IDM"), meaning it both designs and fabricates its own silicon photonics components. Lumos specializes in the design, fabrication, and sale of silicon photonics components and module

III. THE PATENTS-IN-SUIT AND ACCUSED PRODUCTS A. Asserted Patents — Summary OWS asserts infringement of four U.S. utility patents, each of which covers a distinct but interconnected subsystem within high-speed silicon photonics optical transceiver technology. The four patents collectively address the principal functional elements of a silicon photonics transceiver chipset — waveguide coupling, photodetection, wavelen

IV. PRIMARY DAMAGES THEORY: REASONABLE ROYALTY UNDER 35 U.S.C. § 284 A. Legal Framework The primary damages theory in this case is a reasonable royalty under 35 U.S.C. § 284, which provides that "the court shall award the claimant damages adequate to compensate for the infringement, but in no event less than a reasonable royalty for the use made of the invention by the infringer, together with interest and costs as f

V. GEORGIA-PACIFIC FACTOR ANALYSIS FRAMEWORK A. Overview. The 15 Georgia-Pacific factors provide the principal analytical structure for determining the reasonable royalty rate in the hypothetical negotiation between OWS as willing licensor and Lumos as willing licensee. The factors are designed to capture the full range of considerations that would inform a rational economic bargain between the parties, including the
