“The protection of new ideas and methods, and the routes of products to market and stewardship of established brands for me is really satisfying and I enjoy being part of the process to guide, protect and support clients and their businesses through their acknowledged creativity.

“Pragmatic and market savvy, there is no substitute for a keen commercial approach, establishing early on what the best outcome would be for my client and working hard to achieve just that – an out of court settlement or court proceedings if required. Firm and well informed, I have been involved in two leading patent cases in the Court of Appeal. I work with trade mark attorneys on litigation and advise high profile UK and international brands, working closely with our in-house counsel initiative."
