China's Supreme People's Court has rejected InterDigital's appeal regarding an AV1 and VP9 codec patent, marking the company's ninth consecutive appellate defeat in the country. The ruling upholds a previous decision to invalidate several patent claims for lack of inventive step, impacting InterDigital's intellectual property portfolio in the video codec space.
This ruling significantly diminishes InterDigital's ability to collect royalties on AV1 and VP9 implementations within the world's largest hardware market. By upholding the invalidation of key claims for lack of inventive step, the Chinese judiciary is signaling a high bar for standard-essential patent enforcement, favoring local manufacturers like OPPO and Lenovo. This trend complicates the licensing landscape for Western IP holders who rely on global patent pools to monetize video compression technologies. As Unified Patents continues its aggressive invalidation strategy, streaming technology providers should monitor whether other codec patents in the Sisvel or HEVC pools face similar administrative challenges in Chinese courts.
