Recently, Huawei filed a lawsuit against Disney in the Mannheim Regional Division of the Unified Patent Court (UPC), alleging infringement of its European Patent EP3211897 (“Method and Apparatus for Encoding and Decoding Transform Coefficients”) related to HEVC (High Efficiency Video Coding) technology. This case marks Huawei's fourth HEVC-related patent infringement lawsuit filed in the UPC.

Huawei filed the complaint with the Mannheim Regional Division of the UPC in January 2026. According to recently published UPC records, the involved patent EP3211897 pertains to video coding and decoding technology. Beyond this lawsuit, Huawei has previously initiated three HEVC patent lawsuits against companies including Roku and Transsion at the UPC. Furthermore, disputes previously initiated by Huawei as a member of the Access Advance patent pool prompted Roku and Transsion to obtain licenses for the Advance HEVC patent pool.

Disney also faces multiple lawsuits before the UPC. Disney successfully settled with Adeia in December 2025. However, in its parallel litigation with InterDigital, Disney was subject to injunctions issued in Germany and Brazil in February 2026, forcing it to remove Dolby Vision and HDR10+ features from Disney+ subscriptions in Europe. Sharp and Huawei filed HEVC-related patent lawsuits against Disney in Munich Regional Court I in December 2025.

This case is currently proceeding through the UPC litigation process.
