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 can cultivated meat turn its challenges into opportunities?

Ten years ago, ‘cultivated meat’ grown from cells ex vivo left the realm of science fiction and hit the headlines when the “world’s first lab-grown burger” was cooked and eaten at a conference in London. Today, although the first regulatory “greenlight” has been issued in the US, and despite public tastings in Singapore and at the COP27 climate summit, we are still some distance from seeing slaughter-free sausages and steaks in the supermarket.
