MediaTek Inc & Ors v Huawei Technologies Co Ltd & Anor [2025] EWHC 649 (Pat) (18 March 2025)

MediaTek Inc & Ors v Huawei Technologies Co Ltd & Anor [2025] EWHC 649 (Pat) (18 March 2025)

The English court has jurisdiction to try the FRAND, patent infringement, and validity claims as there is a real and substantial connection to the UK, including MediaTek's UK presence and alleged acts. The Chinese proceedings do not resolve the global or UK-specific issues, and there is a real prospect of success on the merits. The anti-trust claim as pleaded is not sustainable and is struck out. Permission is granted to amend the pleadings and to rely on expert evidence of Chinese law. The applications to set aside service and stay the proceedings are dismissed.
