Let me verify the litigation context and the Fiber, LLC case.
Company overview. Lumentum Holdings, Inc. (NASDAQ: LITE), commonly "Lumentum," is a U.S. optical and photonics manufacturer headquartered at 1001 Ridder Park Drive, San Jose, California. It was incorporated in Delaware in 2015 and spun out of JDS Uniphase (JDSU) that August, with corporate heritage the company traces back through JDSU to 1979. It is a public, independently listed company (no parent). Headcount is roughly 10,500–13,800 depending on reporting date, and revenue was about $1.65 billion in fiscal 2025 with trailing-twelve-month revenue near $3.0 billion.
Products / operations. Lumentum designs and manufactures optical and photonic components and systems. Its Cloud & Networking segment supplies semiconductor laser chips, electro-absorption modulated lasers (EMLs), continuous-wave and tunable lasers, photodiodes, pump lasers for submarine transmission, wavelength-selective switches (WSS), optical circuit switches (OCS), and pluggable optical transceivers (400G/800G, with 1.6T ramping). Its Industrial Tech segment sells solid-state, kilowatt-class fiber, diode, ultrafast, and gas lasers for manufacturing, plus lasers used in consumer 3D sensing. End markets are cloud/AI data centers, telecommunications, consumer electronics, and industrial processing. It operates indium phosphide fabs in Japan and, per recent reporting, added a fab in North Carolina.
Patent-litigation posture. Lumentum is an operating company, not a patent assertion entity. In the tracked data it appears once, exclusively as a defendant (0 as plaintiff). That single defendant-side appearance reflects a defense against an outside patent holder, consistent with its profile as a large manufacturer targeted for its WSS/ROADM product lines.
Notable case. The tracked matter is Fiber, LLC v. Viavi Solutions, Inc. (f/k/a JDS Uniphase Corp.) et al., filed August 2015 in the U.S. District Court for the District of Colorado, Denver, naming Lumentum Holdings, Lumentum Inc., and Lumentum Operations LLC. Plaintiff Fiber, LLC, a Wyoming/Denver-based exclusive assignee, asserted U.S. Patent Nos. 6,430,332 and 7,095,917 ("Optical Switching Apparatus") against the defendants' wavelength-selective switches and ROADM products. The case was consolidated with Fiber, LLC v. Ciena (D. Colo. 13-cv-00840); in September 2018 the court entered final judgment of invalidity and non-infringement and dismissed the complaints. The defendants had earlier filed PTAB inter partes reviews through JDSU.
