They are also a pleasure to deal with.

User friendly, pragmatic advice and joined up with colleagues in other practices within the firm. Commercial in outlook but underpinned by unquestionable legal knowledge.

Joel Smith is a true expert in his field. He has an encyclopaedic knowledge of IP and whilst ruthless in litigation matters is extremely calm considered and reassuring.

Practice head(s):

Clare Tunstall


The Pinsent Masons IP team is as strong and mighty as any of the other London IP teams who own more of the limelight. They have been building capability and investing in the stars of the future; razor sharp and energetic junior partners.  I strongly believe that they put the client first and understand this is the path to long-term relationships and success.

A really first-class firm that has very strong partners and associates.

The team is able to take complicated issues, come up with a simple and pragmatic strategy, execute it and deliver what is needed. I have worked with other IP teams who flounder around with complexity and posturing and are incapable of delivering a result. The Pinsent Masons team know their law, but are able to exercise enough pragmatism to deliver a result.

Christopher Sharp is the best. Astute, assured and unflappable. Everything is can-do, delivery is efficient, communication is great and preparedness is excellent. He is a first-class litigator: pushes the right buttons at the right time to bear maximum pressure, and selects the right strategy and tactics for the case rather than drawing from a one-size-fits-all playbook.

I have worked with Nicole Jadeja on a number of matters and I am always impressed with her thoughtful, practical and clear advice. She has great experience working with small biotech companies and is incredibly responsive and helpful.

Charlotte Weekes is an excellent patent litigator. Clever, knowledgeable and focused on the client’s commercial imperatives.

Clare Tunstall is the “Queen of the generic revocation case”. She has done more than anyone else and knows the ropes inside out. She is also fantastic to work with – nothing is too much trouble. Clients love her.

Charlotte Weekes and Samantha Carter are absolute stars.
