## Overview KeeeX brought a patent infringement action before the Paris local division of the Unified Patent Court (UPC) on 17 June 2025, targeting Adobe and OpenAI (JUVE Patent, October 6). The case concerns EP 2 949 070, a patent held by KeeeX relating to a method for verifying the integrity and authenticity of data (JUVE Patent, October 6). The defendants have filed counterclaims seeking revocation of the patent, with multiple related case IDs registered at the UPC: UPC_CFI_530/2025, UPC-CFI-0000003/2026, UPC-CFI-0002285/2025, UPC-CFI-0002281/2025, and UPC-CFI-0002274/2025 (JUVE Patent, October 6). The case on the merits reportedly "kicks off" with proceedings drawing significant attention — described as having "all eyes on Paris" given the prominence of the defendants (JUVE Patent, October 6). ## Why It Matters This is one of the most closely watched UPC disputes involving major AI companies, testing how European patent law applies to data integrity/verification technology potentially relevant to AI training or content provenance systems. The outcome could set precedent for patent enforcement against large AI/tech firms within the UPC system, which has rapidly become a central venue for pharma and tech patent battles in Europe. ## Key Facts - Plaintiff: KeeeX (patent holder) - Defendants: Adobe, OpenAI - Patent at issue: EP 2 949 070 - Venue: UPC Paris local division - Filed: 17 June 2025 - Merits hearing: October 2026 ## Developments to Watch - Outcome of validity counterclaims (revocation bids) - Any injunctive relief granted against Adobe/OpenAI products - Broader implications for AI companies' patent exposure in Europe
