Contract analysis

I. Executive Summary The purpose of this memorandum is to advise Vantage Point Capital Partners Fund IV, LP ("Vantage Point" or "VPCP"), as the majority shareholder holding approximately 62% of the outstanding equity of Optiwave Semiconductor Corp. ("OWS" or the "Company"), regarding the material adverse impact of the Markman claim construction order (the "Markman Order") issued on February 17, 2023, by the Honorable

II. Background A. The Litigation Optiwave Semiconductor Corp. filed this patent infringement action on June 3, 2022, in the United States District Court for the Northern District of California, San Jose Division, asserting four U.S. patents against Lumos Photonics, Inc. The case was assigned to the Honorable Edward J. Torvelis and is docketed as Case No. 5:22-cv-03417-EJD. Lumos Photonics, Inc. is a publicly traded c

III. Summary of the Markman Order (February 17, 2023) On February 17, 2023, the Court issued a 34-page order construing all eleven disputed claim terms across the four patents-in-suit. The full text of the Markman Order is attached as Appendix A. A side-by-side comparison chart showing OWS's proposed constructions, Lumos's proposed constructions, and the Court's adopted constructions for each of the eleven terms is a

IV. Impact on Litigation Value A. Infringement Viability Assessment Based on the Markman Order, Calderwood & Harkness has conducted a comprehensive reassessment of the viability of OWS's infringement theories against each of the four asserted patents. The detailed claim-by-claim infringement viability analyses are attached as Appendix C. The summary assessment for each patent is as follows: '567 Patent (U.S. Patent N

V. Impact on Patent Portfolio Valuation A. The Four Asserted Patents The most immediate valuation impact of the Markman Order falls on the four asserted patents. Clearpath IP Valuation Services' pre-litigation valuation of these four patents at a collective $42.8 million must be materially revised downward. The Court's narrow constructions do not merely impair OWS's ability to assert these patents against Lumos — the

VI. Impact on OWS Enterprise Value and Exit Considerations For purposes of Vantage Point's investment thesis and exit planning, the Markman Order's impact must be assessed in the context of OWS's overall enterprise value. OWS's enterprise value is driven by several factors, including: (i) the Company's revenue-generating product business (the OWS-400ZR and OWS-800LR chipsets and silicon photonics engines), (ii) the C

VII. Recommended Course of Action A. Settlement Calderwood & Harkness recommends that OWS initiate settlement discussions with Lumos Photonics, Inc. through Lumos's litigation counsel, Brannick Howell & Stein LLP. The objective of these discussions should be to resolve the litigation on the most favorable terms available given OWS's significantly weakened post-Markman posture, while minimizing further expenditure of

VIII. Conclusion The Markman Order issued on February 17, 2023, in Optiwave Semiconductor Corp. v. Lumos Photonics, Inc., Case No. 5:22-cv-03417-EJD, represents a materially adverse development for OWS. The Court's adoption of narrow, Defendant-aligned claim constructions on eight of eleven disputed terms substantially eliminates OWS's ability to prove infringement and recover damages from Lumos Photonics.
