The IP team was delighted to have been awarded one of the UK Impact Case of the Year awards at the Managing IP Awards 2026, recognising our work on the Court of Appeal victory in Kohler Mira v Norcros Group.

The Managing IP Awards are widely regarded as the most comprehensive and respected IP law firm awards programme in the legal industry, spanning multiple intellectual property practice areas, and covering more than 50 jurisdictions worldwide.

The Managing IP UK Impact Case of the Year highlights cases that are genuinely groundbreaking and precedent‑setting – those that push legal boundaries, clarify the law. and make a meaningful difference for clients and their industries. Winning in this category is recognition that the work we do makes a genuine difference to our clients – legally, commercially and for the wider market.

The award relates to our successful representation of Norcros Group (Holdings) Limited, trading as Triton, in a long‑running patent infringement dispute brought by Kohler Mira concerning Triton’s DuElec® dual outlet electric shower range.

In a unanimous Court of Appeal judgment handed down in December 2025, the court overturned the High Court’s findings on both validity and infringement. The patent was found to be invalid for insufficiency, and the court also confirmed that Triton’s products did not infringe in any event. The result was a comprehensive victory for Triton, allowing it to continue selling its popular and successful DuElec® products.

The case was led by Nicholas Briggs, partner, supported by Daniel Kelly, legal director, and solicitor Shanice Spencer from our IP litigation team, working closely with Brian Nicholson KC and David Ivison of 11 South Square Chambers.

Commenting on the award, Nicholas Briggs said:

“We’re absolutely thrilled to see this case recognised as one of the UK Impact Cases of the Year. The Court of Appeal’s decision brought much‑needed clarity around patent sufficiency and infringement, and, most importantly, delivered a decisive and commercially important outcome for our client. It was a real team effort, and we’re proud to have helped Triton in achieving a successful conclusion to such a long‑running dispute.”

This recognition is a brilliant moment for our IP litigation team and reflects our ongoing focus on delivering practical, high‑quality advice and results in complex, high‑stakes IP disputes.
