The Unified Patent Court takes jurisdiction to hear a claim concerning the infringement of the UK national part of a European patent, even when the validity of the patent is being disputed
15 of September, 2025
In a decision dated 18 July 2025, the Mannheim Division of the Court of First Instance of the Unified Patent Court took jurisdiction to hear a claim filed against three companies domiciled in Germany for infringement of a classic European patent with effect in Germany and the United Kingdom. The court’s jurisdiction to hear the infringement of the UK national part of European patents is not affected by the fact that the validity of the patent is disputed by the defendants. However, this conclusion does not apply to Spanish national parts of European patents.
