Contract analysis

I. INTRODUCTION AND QUALIFICATIONS A. Purpose and Scope of Report

1. I, Dr. Lawrence Keating, have been retained by Calderwood & Harkness LLP on behalf of Plaintiff Optiwave Semiconductor Corp. ("OWS" or "Optiwave") to provide expert opinions on economic damages arising from the infringement by Defendant Lumicore Technologies, Inc. ("Lumicore") of four United States patents: U.S. Patent No. 10,234,847 (the "'847 Patent"), U.S. Patent No. 10,891,193 (the "'193 Patent"), U.S. Patent

2. I have been asked to analyze and quantify the economic damages sustained by OWS as a result of Lumicore's infringement of the Asserted Patents and to present my opinions regarding the appropriate measure of damages in this case. In conducting my analysis, I have considered the full range of evidence available in this litigation, including the parties' financial data, licensing histories, market information, deposi

3. This report presents three damages theories, each grounded in well-established principles of patent damages law and supported by detailed economic analysis: Theory 1: Lost Profits. OWS is entitled to lost-profit damages under the framework established in Panduit Corp. v. Stahlin Bros. Fibre Works, Inc., 575 F.2d 1152 (6th Cir. 1978). OWS and Lumicore are direct competitors in the silicon-photonics transceiver mark

4. Taken together, the total compensatory damages amount to approximately $166.4 million (the sum of lost profits and reasonable royalty). With the recommended enhancement for willful infringement, the total damages demand is approximately $210.0 million. Under more aggressive enhancement scenarios, the total damages could be substantially higher, as detailed in Section VII below.

5. All of the opinions expressed in this report are stated to a reasonable degree of economic certainty.

6. This report addresses damages through the projected trial date of February 2, 2026. For calculation purposes, my damages model runs through the end of the fourth quarter of 2025 (Q4 2025). I reserve the right to update and supplement my calculations as additional data becomes available, including actual accused-product revenue data for FY 2024 and subsequent periods. B.

The Accused Products and Revenue

35. OWS accuses three Lumicore product lines of infringing one or more of the Asserted Patents. The accused products and their associated revenue data are summarized below.

36. The LumiLink 400G-ZR+ is a 400-gigabit coherent optical transceiver module designed for data-center interconnect applications. Lumicore launched the LumiLink 400G-ZR+ in the third quarter of 2022 (Q3 2022). The LumiLink 400G-ZR+ is accused of infringing three of the four Asserted Patents: the '847 Patent, the '193 Patent, and the '562 Patent.

37. According to Lumicore's segment disclosures and financial data produced in discovery, the LumiLink 400G-ZR+ generated revenue of $94.8 million in FY 2023. The gross margin on the LumiLink 400G-ZR+ was 52.1%, based on Lumicore's product-level financial data produced in discovery and designated Highly Confidential — Attorneys' Eyes Only.

38. The LumiLink 800G-DR8 is an 800-gigabit parallel optical transceiver module targeting short-reach data-center interconnect applications. Lumicore launched the LumiLink 800G-DR8 in the first quarter of 2023 (Q1 2023). The LumiLink 800G-DR8 is accused of infringing all four of the Asserted Patents: the '847 Patent, the '193 Patent, the '562 Patent, and the '015 Patent.

39. According to Lumicore's segment disclosures and financial data produced in discovery, the LumiLink 800G-DR8 generated revenue of $128.4 million in FY 2023. Detailed gross margin data for the LumiLink 800G-DR8 has been produced in discovery and designated Highly Confidential — Attorneys' Eyes Only.

40. The LumiEdge 1600G-LR is a next-generation 1600-gigabit long-reach transceiver module designed for campus and metro data-center interconnect applications. Lumicore launched the LumiEdge 1600G-LR in the fourth quarter of 2023 (Q4 2023). The LumiEdge 1600G-LR is accused of infringing two of the four Asserted Patents: the '193 Patent and the '015 Patent.

41. According to Lumicore's segment disclosures and financial data produced in discovery, the LumiEdge 1600G-LR generated revenue of $41.7 million in FY 2023. The gross margin on the LumiEdge 1600G-LR was 58.3%, based on Lumicore's product-level financial data produced in discovery and designated Highly Confidential — Attorneys' Eyes Only. The higher gross margin on this product reflects its premium positioning and t

4. Aggregate Revenue Calculations

42. Total accused-product revenue for FY 2023, across all three accused product lines, was $94.8 million + $128.4 million + $41.7 million = $264.9 million. This figure represents approximately 84.7% of Lumicore's total FY 2023 revenue of $312.6 million, demonstrating the centrality of the accused products to Lumicore's overall business.

43. Based on my preliminary analysis of Lumicore's quarterly segment disclosures and financial data produced in discovery, total accused-product revenue for the period from Q3 2022 (when the first accused product was launched) through Q1 2024 was approximately $378.2 million.

44. I have projected total accused-product revenue from Q3 2022 through Q4 2025, the end of the damages calculation period for this report, at approximately $714.6 million. This projection is based on historical growth trends observed in Lumicore's quarterly disclosures, Lumicore's publicly stated revenue guidance for FY 2024 and FY 2025, customer pipeline data produced in discovery, and industry analyst projections

45. The chronology of events leading to this litigation is relevant to several aspects of my damages analysis, including the determination of the hypothetical negotiation date for the reasonable royalty analysis and the assessment of willful infringement for enhanced damages purposes. The key events are as follows:

46. October 2022: OWS's engineering team identified potential infringement of OWS's patents by the LumiLink 400G-ZR+ transceiver module. This identification occurred shortly after Lumicore's initial commercial shipments of the product in Q3 2022.

47. November 2022: OWS retained Benchmark Semiconductor Analysis, LLC, a leading independent semiconductor reverse-engineering firm, to perform a detailed teardown and analysis of the LumiLink 400G-ZR+ module. Kevin Ng, Lead Engineer at Benchmark, oversaw the teardown.

48. December 12, 2022: Benchmark delivered its teardown report on the LumiLink 400G-ZR+, confirming the use of accused waveguide multiplexer structures and embedded micro-channel heat-sink thermal management technology in the Lumicore product. This report provided the technical basis for OWS's initial infringement contentions and was relied upon by Dr. Caroline Ashford in her infringement analysis.

49. January 15, 2023: FairPoint Licensing Group, LLC (Angela Reeves, Managing Director), acting on behalf of OWS, sent a detailed licensing and notice letter to Lumicore's General Counsel, Raymond Bautista. The letter identified the '847 Patent, the '193 Patent, and the '562 Patent, described OWS's belief that the LumiLink 400G-ZR+ infringed those patents, and invited Lumicore to negotiate a license. This date—Januar

50. February 28, 2023: Lumicore, through its outside litigation counsel Hawthorne Vega & Cruz LLP (Kate Rourke), responded to FairPoint's January 15, 2023 letter. Lumicore disputed infringement of the identified patents and questioned the validity of certain claims.

51. April 20, 2023: An in-person licensing meeting was held in Austin, Texas. The meeting was attended by Angela Reeves (FairPoint Licensing Group, LLC), Rebecca Tanaka (OWS General Counsel), Raymond Bautista (Lumicore General Counsel), and Kate Rourke (Hawthorne Vega & Cruz LLP). According to Ms. Reeves's deposition testimony on December 10, 2024, the parties discussed the identified patents, OWS's infringement cont

52. May 15, 2023: FairPoint sent a supplemental licensing letter to Lumicore, adding the recently issued '015 Patent to the list of asserted patents and expanding the scope of accused products to include the LumiLink 800G-DR8, which Lumicore had launched in Q1 2023.
