IAM Patent 1000

Slingsby Partners is a prosecution boutique whose sole focus is on patents. Superb at drafting bespoke applications to fit any engineering, electronic or physical sciences invention, it eschews a 'cookie-cutter' approach in favour of targeted, commercially sensitive advice. As one client says: "The firm's technical understanding is extremely high, and it is extremely efficient - the best patent attorney firm I have worked with in my career." Name partner and founder Philip Slingsby established it in 2013 and has built it into the outfit it is today. He is "not only excellent in his execution, but a valuable strategic partner: a scientist first and a lawyer second". Prosecution partner David King is a software, electronics and mechanical maven whose advice is "invaluable", to the point where he is essentially trusted as an "in-house adviser" to his clients.
