Context:
- In February 2026, InterDigital sued TCL over video patents in the Unified Patent Court (UPC), Germany, Brazil, India, and the U.S. (February 10, 2026 ip fray article and February 12, 2026 ip fray article). TCL hit back with two Shenzhen suits served on InterDigital in July, seeking global fair, reasonable and non-discriminatory (FRAND) terms for its TVs under InterDigital’s High Efficiency Video Coding (HEVC) portfolio in one case and damages for alleged abuse of dominance in licensing Chinese standard-essential patents (SEPs) in the other (August 4, 2026 ip fray article). A Rio de Janeiro court granted InterDigital a preliminary injunction (PI) over two HEVC patents, ordering TCL to cease implementing HEVC in devices it manufactures, imports, or offers for sale in Brazil (October 27, 2026 ip fray article).
- TCL has repeatedly turned to Chinese courts in global patent licensing disputes. TCL sued Ericsson for abuse of dominance in the Shenzhen Intermediate People’s Court in 2018. In its dispute with Access Advance, TCL brought a similar claim in the same Shenzhen court and asked the Guangzhou Intellectual Property Court to set global HEVC pool rates before taking a pool license in 2024 (August 4, 2026 ip fray article and October 30, 2024 ip fray article). Chinese courts issued antisuit injunctions in three global FRAND rate-setting cases in 2020, with the Wuhan Intermediate People’s Court granting relief in Xiaomi v. InterDigital and Samsung v. Ericsson and the Shenzhen Intermediate People’s Court doing so in OPPO v. Sharp (WTO panel report, sections 2.6.2, 2.6.4 and 2.6.5).
