Mathys & Squire LLP is delighted to have achieved a significant victory for our client DW Windsor Ltd in its patent infringement claim against Urbis Schréder Ltd in the High Court. DW Windsor are a leading British designer and manufacturer of lighting solutions, found in areas such as Tower Bridge, the London Eye, St Paul’s Vista, and the Square Mile in the City of London.
The dispute concerned two patents drafted and prosecuted by Mathys & Squire LLP directed to DW Windsor’s Garda AntiClimb® range, a surface-mounted linear lighting system for illuminating walled pathways.
Nearly two years ago, DW Windsor commenced patent infringement proceedings in the Intellectual Property Enterprise Court with the aim of enforcing its patents and protecting its technology. Schréder denied infringement and counterclaimed for revocation of the patents. By the time of the trial, the issues before the Court were limited to validity.
The trial took place in the Intellectual Property Enterprise Court on 17 and 18 December 2024, and in a judgment handed down on 14 March 2025, Her Honour Judge Melissa Clarke held that key claims of DW Windsor’s patents were valid and therefore infringed. The defendant was therefore unsuccessful in its attempt to seek to revoke D.W. Windsor’s patents.
Andrew White, Partner at Mathys & Squire LLP commented: “We are delighted to secure the resounding victory for our client DW Windsor. DW Windsor is a highly innovative British business with IP at its core.
While litigation is rarely a first choice for many, sometimes it is necessary to stand up for your IP rights and in this case D.W. Windsor were willing to protect their investment by taking enforcement action through the courts.
This judgement confirms DW Windsor’s position as innovators in the field of lighting solutions and that they are not afraid to stand up for their IP rights. It was a pleasure to work with the client Alan Grant, Lucy Marlow of Fox Williams, and Adrian de Froment of Serle Court on this matter.”
DW Windsor added:“We’re delighted with the result of the Judgment and the knowledge that our patents will continue to provide protection to the business.
Innovation has been at the heart of DW Windsor since the business was founded, and our Garda Anti Climb products exemplify our commitment to creating new lighting solutions that improve the status quo by leveraging our considerable experience, embracing technology and challenging convention through innovative design and engineering excellence.
We invest heavily in research and development and encourage free-thinking in our technical team to push the boundaries in lighting product design and as a result invest in intellectual property and protect and enforce those rights should they be infringed.
I’d like to thank and acknowledge the tireless professionalism of our legal team, including Lucy Marlow of Fox Williams, Adrian de Froment of Serle Court and Andrew White of Mathys & Squire who helped secure this victory.”
