InterDigital President and CEO Li-Jen Chen announced during the company's third-quarter earnings call that InterDigital and certain subsidiaries have filed lawsuits against Transsion in three jurisdictions, alleging infringement of multiple cellular essential standard patents and video coding patents.

These lawsuits were filed in September at the Munich Regional Division of the Unified Patent Court in Europe, in September and October at the Delhi High Court in India, and in September at the Commercial Court of Rio de Janeiro in Brazil. InterDigital is seeking injunctive relief and requesting the courts to declare Transsion a “non-cooperative licensee.”

During the conference call, Chen Liren stated that the company signed four new licensing agreements in the third quarter, one of which was with HONOR. This agreement increased the company's annual recurring revenue by $26 million, setting a new record of $588 million.

InterDigital is currently engaged in legal proceedings with Amazon over related patent issues. On October 20, the High Court of England and Wales issued a temporary anti-suit injunction (AASI) against InterDigital and four affiliated companies, aimed at preventing InterDigital from seeking injunctions or other relief in other national courts. Concurrently, the High Court is considering Amazon's request to expedite the trial process.

Notably, Transsion, the defendant, also faces multiple lawsuits in Brazil and Europe. Five members of the Access Advance patent pool—Huawei, Japan's NEC, JVC, U.S. patent operator Sun Patent Trust, and South Korea's Electronics and Telecommunications Research Institute (ETRI)—initiated multiple lawsuits against Transsion between June and July this year, forming a coordinated offensive.

Transsion reached a settlement with Philips on July 16 regarding AAC/USAC standard essential patents and signed its first patent pool licensing agreement with Via LA. This marks Transsion's third known patent license agreement, following those with Qualcomm and Nokia.
