Defendant
8 cases as defendant.
Huawei Device Co., Ltd. ("Huawei Device") is a Chinese consumer-terminal manufacturer and a wholly owned subsidiary of Huawei Device (Shenzhen) Co., Ltd., which is jointly held by Huawei Investment & Holding Co., Ltd., Huawei Technologies Co., Ltd. and Huawei Tech. Investment Co., Limited (per Huawei's own corporate disclosure in VoIP-Pal.com v. Huawei, W.D. Tex.). Registry data lists it as founded 23 November 2012, headquartered in Dongguan/Guangdong, and registered at Huawei's Bantian, Longgang District campus. It is private — Huawei is employee-owned with no public listing. Headcount and revenue are not disclosed separately for this entity; parent Huawei Technologies reported roughly 208,000 employees and CNY 862.1 billion (~US$118bn) revenue for 2024.
Products / operations. Huawei Device handles design, manufacture, procurement, supply chain, sales and service for Huawei's consumer lines: smartphones (Mate, Pura/P and nova series), tablets (MatePad), PCs (MateBook), wearables and audio, mobile broadband, and smart-home/smart-lock and accessory products, plus installation, repair and customer support. It is the operating contracting entity for Huawei's consumer business rather than a licensing vehicle.
Litigation posture. The tracked record contains exactly one case, as plaintiff (1 plaintiff / 0 defendant), at the PTAB — consistent with an operating company bringing defensive validity challenges, not a patent monetization entity.
Notable case. Huawei Device Co., Ltd. v. Fundamental Innovation Systems International LLC (PTAB, filed 11–12 January 2018, e.g. IPR2018-00465, -00485, -00487 et al.). Huawei petitioned against FISI patents on USB charging and power supply for mobile devices (US 7,834,586; 7,239,111; 7,893,655), challenging claims over prior art. FISI is a licensing entity holding patents originating from Research In Motion/BlackBerry, which it asserted against Huawei, LG and ZTE in the Eastern District of Texas; Huawei's IPRs ran parallel to that litigation. Institution was denied in at least some petitions (e.g. IPR2018-00487). The underlying district-court suit is not part of our tracked PTAB-only data set.
Maxell asserted U.S. Patent 7,995,897 against Huawei entity defendants. The '897 patent was listed on the AO-120 § 290 report and in the consolidated P.R. 4-3 claim-construction statement; the case was consolidated with No. 5:18-cv-00034 for pretrial.
Maxell sued Huawei Device USA and Huawei Device Co. in the Eastern District of Texas. Google Patents/Unified Patents linked the case to US 7,324,487, but the narrative could not retrieve the full asserted-patent list; the case was dismissed as settled on April 4, 2019.
Maxell, Ltd. (then Hitachi Maxell, Ltd.) sued Huawei Device USA Inc. and Huawei Device Co., Ltd. in the Eastern District of Texas, asserting U.S. 6,928,292; claims 1 and 2 were construed. The case closed on July 2, 2018, resolved via settlement/license.
Patent infringement action by Hitachi Maxell against Huawei and Huawei Device entities. The case was stayed pending PTAB inter partes review and docket records show it closed on July 2, 2018.
Earlier Eastern District of Texas case in which Maxell asserted U.S. Patent 7,116,438 among other patents against Huawei. Maxell's Notice of Readiness stated this and other earlier E.D. Tex. cases were dismissed and closed; the '438 claim terms were construed in the Huawei action.
Earlier E.D. Tex. action listed in the patent family/litigation record. Per RPX, six patents including U.S. Patent No. 6,928,306 were previously asserted in this District against the Huawei/ZTE/ASUS group; the exact defendant mapping between -00033 and -00034 was not confirmed. A 2018 opinion, Maxell Ltd. v. Huawei Device U.S. Inc., 297 F. Supp. 3d 668, reflects claim-construction activity.
Maxell asserted U.S. Patent 7,203,517 and U.S. Patent 8,982,086 in the Eastern District of Texas against Huawei Device Co., Ltd. and Huawei Device USA, Inc., among other defendants in the family of suits. The case was resolved and dismissed as part of Maxell's settlements.
FISI asserted the '655 patent among others against Huawei. The action was consolidated with the LG action and stayed pending settlement; Huawei filed IPR2018-00479 against the '655.
