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.
