Lumentum Inc.

Lumentum Holdings Inc. (commonly "Lumentum," NASDAQ: LITE) is a U.S. optical and photonics manufacturer headquartered in San Jose, California, with R&D, manufacturing, and sales sites worldwide. It was incorporated in Delaware on February 10, 2015, and became an independent public company on August 1, 2015, when JDS Uniphase Corporation (JDSU) spun off its Communications and Commercial Optical Products business plus the WaveReady line; JDSU was simultaneously renamed Viavi Solutions Inc. and initially retained ~19.9% of Lumentum's shares. Lumentum is publicly traded and not a subsidiary. Its FY2025 (ended June 28, 2025) 10-K reported net revenue of ~$1.65 billion and roughly 10,562 employees.

Products / operations. Lumentum reports two segments. Cloud & Networking supplies optical and photonic components, modules, and subsystems to cloud data-center operators, AI/ML infrastructure providers, network-equipment makers, and communications service providers — including wavelength-selective switches (WSS) and ROADM products, 100G EML laser chips, transceivers/active optical cables, and diode lasers for 3D sensing. Industrial Tech sells short-pulse solid-state lasers, kilowatt-class fiber lasers, diode lasers, ultrafast lasers, and gas lasers for precision manufacturing. It is an operating company with real products, not an NPE; it has grown partly by acquiring businesses such as Oclaro's optical business, NeoPhotonics, and Cloud Light Technology.

Patent-litigation posture. Across tracked U.S. cases Lumentum appears only as a defendant (1 case, 0 as plaintiff). This is the profile of an operating company being sued rather than an entity asserting patents. The single tracked matter was filed in the District of Colorado, Denver — not a plaintiff-friendly venue like the Eastern District of Texas.

Notable case. Fiber, LLC v. Viavi Solutions, Inc. (f/k/a JDS Uniphase Corp.) et al., No. 1:15-cv-01743 (D. Colo., filed Aug. 12, 2015), named Lumentum Holdings Inc., Lumentum Inc., and Lumentum Operations LLC alongside Viavi. Plaintiff Fiber, LLC — a Wyoming LLC asserting two acquired optical-switching patents (U.S. 6,430,332 and 7,095,917) against WSS/ROADM products — is characteristic of a patent-assertion entity. The suit was consolidated with earlier Ciena and Finisar actions; the court entered final judgment of invalidity and non-infringement on September 13, 2018, which the Federal Circuit affirmed in 2019.
