The Paris Local Division of the Unified Patent Court conducted an interim conference on July 29, 2026, addressing the infringement case (UPC_CFI_362/2025) filed by Sun Patent Trust against Vivo Mobile Communication entities, with a counterclaim for patent revocation (UPC_CFI_001786/2025). The patent in dispute is EP3407524, held by Sun Patent Trust. During the conference, both parties were open to negotiations and confirmed the value in dispute as 10 million euros, evenly split between the infringement action and the counterclaim. Confidentiality issues were discussed, particularly regarding FRAND matters, leading to planned public and non-public hearings. The main legal points include claim interpretation, patent validity focusing on added matter, and alleged infringement by Vivo's 4G+ compatible devices. A detailed schedule for the oral hearing in September 2026 was outlined. The order demands submissions by August 28, 2026, on consolidated requests and recoverable costs.
