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."

Chambers UK

Leading Firm
The Chambers Guides have been ranking the best law firms and lawyers since 1990, and now cover 185 jurisdictions throughout the world. 

They really get the science, they keep up to date with research developments as well as the law.

Their IP pedigree is excellent. 

Legal 500

Nottingham-based Potter Clarkson LLP has expertise in clearance, filing, prosecution and contentious work. John Peacock is a key figure and assisted the Elvis Presley Estate in opposing the trade mark of 'Elvis Juice' and 'Brewdog Elvis Juice' by drinks manufacturer Brewdog. He also advised Frederickson & Byron, which acted behalf of the Estate of Prince, in relation to infringement proceedings by a proposed West End musical titled 'Purple Rain'. Sanjay Kapur is also a key figure and is 'easy to deal with', 'responsive' and 'commercial'.

We are proud to be one of over 100 patent and trade mark firms to have so far signed up to the IPInclusive charter which came into force back in 2016.

Backed by The Chartered Institute of Patent Attorneys (CIPA), The Chartered Institute of Trade Mark Attorneys (CITMA), The IP Federation (IP Fed), The UK association of the International Federation of Intellectual Property Attorneys (FICPI-UK) and The UK Intellectual Property Office (UK IPO) this pan-professional taskforce, made up of over 40 member organisations, is committed to making IP professions more inclusive and encourages both current and future IP professionals to encourage others to embrace and sustain a more diverse workforce.

The IPInclusive charter states:

"We will support equality, diversity and inclusion by: 
  • - Having in place a named individual within our organisation as Equality, Diversity and Inclusion officer. This person will be sufficiently senior to make change happen and to be accountable for our progress. 
  • - Having in place a written Equality, Diversity and Inclusion (“EDI”) policy for our organisation and making everybody in the organisation aware of it. 
  • - Promoting openness and transparency so as to demonstrate merit-based equal opportunities in our recruitment and career progression processes. 
  • - Acknowledging the effects of unconscious bias and introducing measures to tackle it. 
  • - Monitoring and reporting internally on our progress using measures and at intervals that are appropriate to our size and nature.
  • - Sharing our experience within the IP Inclusive community to help build an effective network for equality, diversity and inclusion across the IP sector.”

Having been involved with IP Inclusive right from concept stages, with one of our partners, Stephanie Pilkington, being a member of CIPA's task force, we have continued to support this charter. Our Practice Director, Andrew Argyle, a non-practising solicitor, has taken on the role of EDI officer. An EDI policy has been prepared and published internally.

Potter Clarkson is active in supporting IPInclusive’s recent initiative, “Careers in Ideas”, which is designed to promote more widely the IP profession as a career, in particularly targeting universities and schools.
