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.

Trade secrets can supercharge life science start-ups, if founders know how to use them

Think back to school. As soon as you shared a secret, there was no chance you’d ever get control of it back. In the same way, preventing the theft of ideas through corporate espionage or other means presents challenges. What is clear to the perpetrators is the value that trade secrets hold. But what is under-appreciated by many in the life sciences is just how many trade secrets they might have and just how much value they can secure by protecting them.
