Recently, Ericsson filed lawsuits against Transsion in Brazil, India, Nigeria, and the Unified Patent Court over standard-essential patents (SEPs) related to 4G and 5G technologies.

Ericsson stated that it has been negotiating with Transsion since August 2017, but Transsion has persistently rejected its FRAND-compliant licensing offers, forcing Ericsson to pursue legal action. Transsion's “prolonged delay tactics” have disrupted the telecom innovation cycle and adversely impacted competitors who have legitimately obtained patent licenses.

According to Canalys data, Transsion—dubbed the “King of African Phones”—maintained a dominant 51% market share in Q2 2025. On the evening of November 12, Transsion Holdings announced plans to issue shares overseas (H-shares) and list on the Hong Kong Stock Exchange's main board. However, the company is embroiled in multiple global lawsuits concerning essential patents for cellular communication and video coding standards. InterDigital filed lawsuits against Transsion in October at the Unified Patent Court and courts in India and Brazil over cellular communication standard essential patents and video coding patents.

Concurrently, Transsion faces a series of lawsuits initiated by the Access Advance patent pool and its licensees—including Huawei and the Electronics and Telecommunications Research Institute of South Korea—in the Unified Patent Court and Brazilian courts.

Additionally, Transsion has reached settlements with Qualcomm and Philips this year, and signed a patent licensing agreement with Nokia without litigation.
