Huawei Device Co., Ltd. — also registered as Huawei Device (Shenzhen) Co., Ltd. — is a Chinese consumer-electronics company headquartered in Shenzhen, Guangdong. Corporate registry data (via Tianyancha) places its establishment in November 2012 with registered capital of RMB 606 million. It is not independently public: it is wholly owned by Huawei Device (Shenzhen) Co., Ltd., which is held by Huawei Investment & Holding Co. (67.95%) and Huawei Technologies Co. (32.05%). Huawei Technologies is a private, employee-owned company founded in 1987; no public ticker exists. Third-party data aggregators (PatSnap) list a 10,000–50,000 employee band for this entity; standalone revenue for the legal entity is not publicly disclosed.
Operations. Per its TL 9000 quality registration, the company's scope covers design, manufacture, procurement, supply-chain management, sales and service of digital entertainment products, telecommunication terminal products (including mobile phones), computers, smart-home devices, smart locks and accessories. Its consumer product lines include smartphones, tablets, PCs, wearables and CPE routers/wireless modems.
Patent-litigation posture. This is an operating company, not a non-practicing entity. Across tracked records it appears in exactly one case, solely as a defendant (0 as plaintiff), consistent with a hardware vendor being targeted rather than asserting patents. The single appearance is in a U.S. International Trade Commission Section 337 action.
Notable case. Technology Properties Limited LLC et al. v. Acer Inc. et al., ITC Inv. No. 337-TA-853 (complaint filed July 24, 2012; instituted August 21, 2012). Complainants Technology Properties Limited, Phoenix Digital Solutions and Patriot Scientific — licensors of the "MMP Portfolio" — asserted U.S. Patent No. 5,809,336 ("High Performance Microprocessor Having Variable Speed System Clock") against roughly two dozen consumer-electronics respondents, including Huawei Technologies, Huawei Device and Huawei's U.S. affiliates. The presiding ALJ found no violation of Section 337 in September 2013, and the Commission reviewed only selected claim-construction, infringement and domestic-industry issues; several respondents, including Acer and Amazon, settled out. No exclusion order issued against Huawei on the tracked record.
