I'll research Maxell Holdings, Ltd. to verify its profile and litigation posture.
Maxell Holdings, Ltd. / Maxell, Ltd. — Tokyo-based manufacturer. The case data names the entity "Maxell Holdings, Ltd.," but the company renamed itself Maxell, Ltd. in October 2021 on dissolving its holding-company structure; the tracked plaintiff appears as "Maxell, Ltd." It is headquartered in Minato-ku, Tokyo, with a second head office in Oyamazaki, Kyoto, and was established in September 1960 (incorporated 1947), formerly known as Hitachi Maxell. It is publicly listed on the Tokyo Stock Exchange (ticker 6810), with a market cap of roughly US$600M and consolidated headcount of about 3,765 (as of March 31, 2026). Reported trailing revenue is roughly ¥128bn (approximately US$860M). It is independent, having exited the Hitachi group structure in 2017.
Products / operations. Maxell is an operating manufacturer, not a shell. It sells coin-type lithium and other primary/secondary batteries and battery electrodes (Energy); adhesive tapes including semiconductor-process and construction tapes, coated separators, and industrial rubber products (Functional Materials); automotive optical components such as in-car camera lens units and LED headlamp lenses, semiconductor embedded systems, and electroformed parts (Optics & Systems); plus projectors, electrical tools, and health/beauty products (Electric Appliances/Consumer).
Litigation posture. In this database Maxell appears once, as plaintiff, in the Eastern District of Texas (Marshall/Tyler Division) — zero defendant appearances. That profile reflects an operating company running a patent-monetization campaign rather than a company absorbing NPE suits. Maxell has separately enforced a broad portfolio against smartphone and consumer-electronics makers (including Apple, ZTE, Lenovo/Motorola Mobility, and Samsung) in district court and at the ITC, so it functions as an active licensor-assertor with real production operations.
Notable case/context. The tracked matter, Maxell, Ltd. et al. v. Samsung Electronics Co., Ltd. et al., is part of a multi-front dispute stemming from the 2011 expiry of a license between Samsung and Maxell's predecessor. In May 2025 an E.D. Tex. jury awarded Maxell about $112M on three patents; in September/October 2025 the court granted Samsung judgment as a matter of law, overturning the verdict on noninfringement of all three patents and invalidating two. Related E.D. Tex., ITC (337-TA-1432), and parallel foreign actions remain pending, with a second Samsung case stayed pending IPR.
