Defendant
1 case as defendant.
TCT Mobile (US) Holdings, Inc. is the U.S. holding company for the American operations of TCT Mobile, the handset unit of China's TCL Communication Technology Holdings Limited (formerly HKSE: 2618, taken private by TCL in 2016). It was incorporated in Delaware and registered in California on March 23, 2012; its principal address is 189 Technology Drive, Irvine, California (an earlier address of record was 25 Edelman, Irvine). California corporate filings list it simply as a "holding company." It is the parent of TCT Mobile, Inc. and TCT Mobile (US), Inc., which distribute mobile handsets in the United States. Public sources put the wider TCT/TCL Communication organization at roughly 11,000 employees worldwide; no separate revenue or headcount for the U.S. holding entity is publicly disclosed.
Operations. TCT Mobile designs, develops and markets mobile phones, tablets and mobile-broadband devices under the Alcatel (originally "Alcatel OneTouch") and TCL brand names, sold in the U.S. through carriers and retailers including Walmart, Best Buy and Amazon. The U.S. holding/subsidiary entities handle domestic distribution rather than manufacturing; TCL Communication's operating and design entities are in Shenzhen, Huizhou and Hong Kong, and the Alcatel brand itself is licensed from Nokia. This is an operating-company group, not a patent-assertion vehicle.
Litigation posture. The tracked case data show one appearance, as a defendant — consistent with an operating company being attacked rather than asserting patents. The suit is Fundamental Innovation Systems International LLC v. TCT Mobile (US) Inc. et al., filed April 2020 in the U.S. District Court for the District of Delaware (No. 1:20-cv-00552). Fundamental Innovation Systems International LLC is characterized by RPX as an NPE; it acquired BlackBerry-originated patents covering USB charging and connectivity, and the asserted portfolio includes U.S. Patent Nos. 6,936,936, 7,239,111, 7,834,586 and 8,624,550. Delaware, a common venue for such suits, is not an Eastern District of Texas forum.
Context. The TCT defendants countered through inter partes review at the PTAB (e.g., IPR2021-00599, where the Board found all challenged claims of the '586 patent unpatentable). TCT Mobile (US) Holdings, Inc. appears in the record as a real party-in-interest in those petitions; related actions against Lenovo/Motorola and Coolpad involved the same NPE portfolio.
Family-level FISI enforcement action against TCT Mobile and TCL entities in the District of Delaware, listed as docketed. The narrative does not confirm that 8541983 specifically was asserted.
