UK comparable trade marks: grace period ends soon

As 2025 draws to a close, brand owners face an important deadline that could affect their UK trade mark rights. From 1 January 2026, it is no longer possible to rely on evidence of use in the EU to maintain the validity of UK comparable trade marks (often called “Brexit clones”). This marks the end of the grace period for use, originally set out in the UK/EU Withdrawal Agreement.

UPC Court of Appeal leaves door open to parties relying on file prosecution history when construing claims

On 13 May 2024, the UPC Court of Appeal (CoA) upheld a decision of the Munich Local Division (MLD), primarily directed to the approach to claim construction. This was in the context of a preliminary injunction application brought by the patentee, which was dismissed at first instance and on appeal. In its decision, the CoA did not, however, address whether or not the file wrapper could be referred to in order to assist in interpreting patent claims in the UPC.
