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.

Maximising the value of your 3D printing innovations: Patents and trade secrets

3D printing is now a widespread technology that may have seemed as fanciful 100 years ago as Star Trek's replicators do to us now. We may be a long way off from synthesising matter from light to create food and other objects at will but even this fictitious invention was a development on earlier technologies (protein sequencers and food synthesisers).

The other problem with tech transfer

There has been increasing discussion around problems with the transfer of technology from universities, and in particular with the spin-out process. The process is often very slow, with negotiations around terms such as the equity stake taken by the university sometimes causing investors to walk away, founders to get frustrated, and companies struggle to get off of the ground.

Trade secrets - the forgotten IP right

Trade secrets are an important component of any company’s intellectual property assets. They may even be the crown jewels of their portfolio - they just may not know it. And even if they do know, sometimes an organisation’s internal processes are simply not robust enough to protect these valuable secrets.

When AbbVie and Amgen agreed a settlement over Humira back in 2017, the prospect of AbbVie’s blockbuster drug being impacted by biosimilar competition seemed a long way in the future. However, it has now not only come and gone but has also arguably heralded in the age of the ‘patent cliff’.

Is AI about to revolutionise agritech?

Farming is one of the world’s most important industries. Arguably as the food crisis worsens, it will continue to become even more important. As it does, farmers will need help to increase crops yield and livestock growth.
