Recently, TCL filed two separate lawsuits against InterDigital with the Shenzhen Intermediate People’s Court (hereinafter referred to as the Shenzhen Intermediate Court), involving the determination of global FRAND licensing rates for HEVC standard-essential patents and civil antitrust claims. This marks the first time TCL has brought the litigation back to China since the two parties launched a global, multi-jurisdictional patent battle in February 2026.

TCL has requested that the court rule that the licensing terms for the HEVC patent portfolio offered by InterDigital violate the FRAND principles and that the Shenzhen Intermediate Court establish globally binding public licensing terms. Additionally, TCL has filed a civil antitrust lawsuit regarding standard-essential patents, alleging that InterDigital used litigation to coerce negotiations and abused its dominant market position to extract excessive licensing revenues.

Starting in February 2026, InterDigital announced patent infringement lawsuits against TCL and Hisense in Europe, Germany, Brazil, and India, and filed a Section 337 investigation petition with the U.S. International Trade Commission (ITC), alleging that the relevant products infringed on six of its patents. In response to the lawsuits, Hisense has filed an administrative complaint with Brazil’s antitrust agency, CADE, while TCL has launched a counterattack in the Shenzhen Intermediate People’s Court.
