Sudden! The United States once again launches Section 337 investigation against TCL and other Chinese companies

This investigation was initiated from a complaint submitted to the ITC by South Korea’s Pantech Corporation on July 3, 2025. The company claimed that certain mobile cellular communications equipment exported to, imported and sold in the United States were suspected of infringing on four U.S. registered patents it held (patent numbers were 9.548.839, 11.659.503, 11.051.344, and 12.267.876), and requested the ITC to issue a limited exclusion order and injunction to prevent the allegedly infringing products from entering the U.S. market.

In addition to the above investigation, on August 4, Cerence Operating Company of the United States filed an application with the U.S. International Trade Commission in accordance with Section 337 of the U.S. Tariff Act of 1930, claiming that Certain Smart Televisions exported to, imported and sold in the United States violated Section 337 of the United States.
