About Us


Baron Warren Redfern is a medium sized firm of UK and European Patent and Trade Mark Attorneys.

We practise in all areas of intellectual property, including Patents, Trade Marks and Registered Designs, as well as other areas such as Unregistered Design Rights and Copyright.

Our London Patent Attorneys have particular skills in a wide range of technical fields, from mechanical, electrical and electronic engineering, including telecommunications, signal processing and laser technology, to the chemical and biochemical fields. Our clients on the patent side include TE Connectivity, Uni-Charm, Pepperl & Fuchs and Brightwell Dispensers.

In Trade Marks we represent companies with a host of high profile brand names, including Peugeot Citroen, Haribo, Valentino, Topps Tiles, Designers Guild and Ally Capellino, and our London Trade Mark Attorneys have particular experience in UK and international registration, enforcement, anti-counterfeiting and domain name disputes. We also help many SMEs and start-ups to protect their brand names.

Baron Warren Redfern was formed out of the merger of Baron & Warren and G.F. Redfern & Co in 2008. The merger brought together two firms of long standing in the field of Intellectual Property, with G.F Redfern & Co having its origins dating back to 1830 and Baron & Warren dating back to 1924.

Our offices are conveniently located in Brentford, West London.
