Core Viewpoint - The ongoing patent dispute between MediaTek and Huawei has intensified, with MediaTek's subsidiary HFI Innovation filing a lawsuit against five Huawei subsidiaries for infringing on a European patent, indicating a retaliatory response to Huawei's previous claims against MediaTek [1][2]. Group 1: Patent Disputes - MediaTek's lawsuit in the European Unified Patent Court is a continuation of the patent conflict that began in 2022, highlighting the escalating tensions between the two companies [1][2]. - Huawei initiated several lawsuits against MediaTek in China in May and August 2023, claiming infringement of its Chinese patents related to mobile communication technologies [2]. - MediaTek's counteraction includes a lawsuit filed in July 2024 in the UK, accusing Huawei of infringing on three of its 4G/5G patents and seeking an injunction [3]. Group 2: Background of the Dispute - The patent battle traces back to March 2022 when Huawei sought licensing fees from MediaTek for its essential 5G patents, but negotiations failed due to MediaTek's refusal based on FRAND (Fair, Reasonable, and Non-Discriminatory) terms [2]. - Following the unsuccessful negotiations, Huawei filed a patent infringement lawsuit against MediaTek in May 2024, which may involve various mobile communication technologies [2].
