China’s Huawei Technologies Co. Ltd. and U.S.-based telecommunications research and development company InterDigital Inc. are embroiled in another patent licensing dispute after reaching an agreement in a similar dust-up two years ago.

InterDigital’s chief legal officer, general counsel and corporate secretary, Jannie Lau, reported to the U.S. Securities and Exchange Commission on Jan. 7 that Huawei had sued InterDigital and several of its subsidiaries in the Shenzhen Intermediate People’s Court in China five days prior.
