Managing Intellectual Property

Tier 1 Patent Prosecution
The results of MIP's annual research are detailed rankings of the leading firms practising intellectual property in each country. The leading UK firms are presented in the form of 34 firms split into five tiers; we are one of 24 attorneys listed within the top three tiers, with an additional 10 listed as ‘notable’ firms, those in the top tiers received the most recommendations for the quality and depth of their practice. The survey reveals which firms are rated by their peers for the strength of their expertise and the depth of their ability to service clients. Richard Basset is currently listed as an IP Star.
The 2016 survey stated:

Potter Clarkson has an outstanding reputation in patent prosecution work.
This “commercially-focused” and “client-centric” firm is home to experienced European patent attorneys such as Robert Pugh, Ray Charig, Caroline Marshall, Saiful Khan and Richard Bassett – all recommended in their fields. “Their quality of work is world class and the attorneys and support team are of high calibre”. 

Client testimonials included:
“We selected Potter Clarkson over other firms because of their technical reputation.”
“We trust Potter Clarkson with our core IP and value their expertise in our sector.”

“It’s been a pleasure to witness the speed and ease at which the patent attorneys grasp new technical matters.”

“Their advice takes into consideration the international and dynamic nature of our business, and they behave as members of our team rather than simply as service providers.”

Others praise the "very good experience of the backroom staff" and say it has "a professional edge" they have never encountered in any patent agency before, particularly noting how well the team works together. "The smaller teams seem to have good group dynamics and mentor their upcoming counsel well as they move through the ranks within the firm."
