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.

How will Emotional Perception impact the patentability of AI in the UK?

In the potentially ground-breaking decision on Emotional Perception delivered late last year, the High Court found that a claim relating to a trained artificial neural network (ANN) did not fall foul of the recognised non-patentable subject matter exclusion for being a "computer program as such". However, the UK Intellectual Property Office (IPO) is now appealing the decision to the Supreme Court. Whatever the final verdict on Emotional Perception’s case, the rationale adopted by the Court looks set to have a lasting impact on the patentability of AI in the UK.
