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.

EPO hints at accepting the ‘PCT joint applicants’ approach for priority

The EPO’s Enlarged Board of Appeal has issued a communication hinting that it is likely to endorse the so-called PCT joint applicants approach to priority. This should come as a relief to those with pre-AIA US priority applications. It also suggests a slightly more permissive view on priority entitlement, which could be favourable for patentees and applicants in a wider range of situations.

Lidl v Tesco: Lord Justice Arnold reverses strike out of Tesco’s bad faith counterclaim

In the latest development in the intellectual property fight between Lidl and Tesco, the Court of Appeal has overturned a High Court ruling to strike out Tesco’s bad faith counterclaim. We can now expect the Court to consider whether Lidl’s actions constitute bad faith by repeatedly filing the same mark (‘evergreening’), where the mark may have been obtained for the purpose of bringing legal proceedings, and despite it not being registered strictly in the form that it is used.
