InterDigital announced that Huawei has filed a patent infringement suit against the company in China. This follows the expiry of InterDigital's licence agreement with Huawei at the end of 2018.
In a regulatory filing, InterDigital said the civil complaint was filed on 02 January by Huawei in the Shenzhen Intermediate People’s Court. The complaint seeks a ruling that InterDigital violated an obligation to licence its patents essential to the 3G, 4G and 5G standards on fair, reasonable and non-discriminatory terms and conditions. Huawei also wants the court to set terms for Huawei to license Interdigital's Chinese standards-essential patents for its phones and other devices.
