D.W. Windsor Ltd has recently achieved a significant victory in its patent infringement claim against Urbis Schréder Ltd. D.W. 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.
In this case, the patents in question concerned the incorporation of an anti-climb measure into a lighting support. The decision serves as a reminder that patents may provide strong protection for innovative and cutting-edge product design.
Nearly two years ago, D.W. 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.
In a Judgment handed down on 14 March 2025, Her Honour Judge Melissa Clarke held that key claims of D.W. 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.
Lucy Marlow, the lead lawyer on the case, has recently joined Fox Williams and commented:
“This Judgment marks a resounding victory for our client, D.W. Windsor. It serves as a reminder of the importance for innovative businesses to protect and enforce their inventions, whether that concerns either seemingly simple or complex technology. It has been pleasure to work alongside D.W. Windsor on this matter, as well as the legal team, including Adrian de Froment of Serle Court and Andrew White of Mathys & Squire. I am delighted to continue advising clients on complex IP disputes as part of the Fox Williams team.”
Alan Grant,Design and Development Director at D.W. Windsor added:
“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.”
