Summary: The Hague Local Division disposed of revocation counterclaim UPC_CFI_1708/2025 under R. 360 RoP as devoid of purpose, EP4066856 having been finally revoked at the EPO, with GSK bearing the defendants' costs as the unsuccessful party. The decision on the stay request was postponed, the 30 September 2026 hearing cancelled, and the parties given the opportunity to brief the impact of the forthcoming written TBA decision on divisional EP4226941.
