Ericsson has recently filed new lawsuits against Transsion in Indonesia, Colombia, and Morocco. This marks the first time major SEP holders like Ericsson have initiated public SEP infringement litigation in Morocco.

Robert Earle, Vice President at Ericsson, stated that since August 2017, Ericsson has been negotiating with Transsion and has proposed arbitration terms consistent with FRAND principles. However, Transsion continues to “use without compensation” Ericsson's patented technologies without authorization and persistently rejects its FRAND-compliant licensing offers, compelling Ericsson to pursue legal action. Consequently, new lawsuits have been filed with the Judicial Representation Office of Colombia's National Regulatory Agency for Industry and Commerce, the Civil Circuit Court of Bogotá, the Commercial Court of the Central District of Jakarta, and the First Instance Commercial Court of Casablanca. In November this year, Ericsson also sued Transsion in Brazil, India, Nigeria, and the Unified Patent Court over 4G and 5G standard-essential patents.

It is reported that InterDigital also filed lawsuits against Transsion in October 2025 at the Unified Patent Court and courts in India and Brazil over cellular communication standard-essential patents and video coding patents.
