Triton successful in patent infringement appeal against Kohler Mira

Triton Showers has revealed it will continue to sell its leading range of DuElec® electric showers in the UK and Ireland, following its victory in the Court of Appeal in a long-running patent infringement action brought by Kohler Mira. In its judgment dated 22nd December 2025, the Court of Appeal unanimously overturned the lower court’s findings of both validity and infringement of the patent in question, which concerned Triton’s range of dual outlet electric showers.

This follows an initial court ruling in December 2024, which found in favour of Kohler Mira. Working with law firm Shakespeare Martineau, Triton subsequently secured permission to appeal the decision.

Phil Viner, MD at Triton Showers, said: “Over recent years, we have been working towards resolving a legal dispute concerning the DuElec® electric shower. During this time, our legal team has vigorously defended Triton’s position, and the Court of Appeal has now ruled in Triton’s favour.

“We are therefore pleased to confirm that Triton will continue to sell its highly successful range of DuElec® electric showers in the UK and Ireland, as it has done since the product was launched in May 2022. We would like to extend our thanks to the Shakespeare Martineau legal team for helping us to secure this comprehensive outcome.”

“We would also like to thank our valued customers for their support during this period and look forward to building further plans to optimise our range with them.”

Nicholas Briggs, head of intellectual property at law firm Shakespeare Martineau, said: “This is a great result for our client. Their determination to pursue the appeal for what both they and we thought all along was the right result has been fully justified.”
