Core Viewpoint - The ongoing patent litigation between MediaTek and Huawei reflects a strategic confrontation in the global patent landscape, particularly focusing on the transition from 4G to 5G technologies and the evolving business models for patent licensing [2][5][6]. Group 1: Patent Litigation Overview - MediaTek's subsidiary HFI Innovation has filed a patent infringement lawsuit against five Huawei subsidiaries, targeting the European patent EP2689624 related to LTE core technology [1]. - The lawsuit comes four months after Huawei initiated its own legal action against MediaTek regarding 5G patents, indicating a reciprocal legal strategy between the two companies [1][2]. Group 2: Historical Context and Developments - The conflict originated from failed 5G patent licensing negotiations in March 2022, where Huawei proposed a chip-level licensing fee of $2.5 per device, which MediaTek deemed inconsistent with industry practices [2]. - Huawei initiated its first lawsuit against MediaTek in May 2024, claiming $46.2 million for alleged infringement of its 5G patent portfolio, leading to multiple lawsuits across various Chinese cities [2][3]. Group 3: Judicial Landscape - The litigation has created a tripartite judicial confrontation in China, the UK, and Germany, with MediaTek winning a key ruling in the UK confirming its right to set global FRAND rates [3]. - In China, the Supreme People's Court has upheld jurisdiction for cases in Guangzhou and Zhengzhou, moving towards technical assessments [3]. Group 4: Patent Ownership and Market Impact - As of the end of 2024, Huawei holds 14.59% of global 5G standard essential patents (SEPs), leading the market, while MediaTek is focusing its litigation efforts in Europe and the UK [4][5]. - The outcome of these lawsuits could significantly reshape the patent cost structure for Chinese smartphone manufacturers, potentially reducing patent expenses by 30%-40% if Huawei's chip-level licensing model gains traction [8][10]. Group 5: Implications for Industry Standards - The ongoing patent battle is seen as a critical case for assessing the adaptability of global patent rules, with implications for the semiconductor industry where IP disputes account for 47% of litigation cases [9]. - The results of the litigation could influence the transition from a "terminal payment" model to a "chip payment" model in the telecommunications industry, affecting cost structures for companies like Xiaomi and OPPO [10].
