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.

Who owns AI-generated works?

Businesses are continuing to find new ways to take advantage of AI. Large language models such as ChatGPT can be used to edit marketing copy, write computer code, generate images, and automate workflows. The recent ruling of a US federal court that AI-generated art cannot be copyrighted was therefore met with quite substantial consternation. Innovators want to use AI, but they are worried about protecting their creations and works.

The impact of REULA on copyright law: navigating the post-Brexit landscape

The Retained EU Law (Revocation and Reform) Act 2023 (REULA) came into force on 1 January 2024 and has some significant implications for IP law. Much IP law in the UK is derived from EU law - both implemented EU law and case law decided in view of EU law. REULA could impact all of the above.

Fashionable patterns and IP

Some luxury fashion houses have their own signature patterns: The Burberry check, Louis Vuitton Damier Azur and Prada Symbole being the most famous examples. These are notably printed across luggage and accessories with the print as the main feature. On clothing, the pattern is usually applied more subtly, such as on the lining of a jacket, across the collar, or as even more discreet features, such as on the hem.
