Stuart Baran

Called to the bar 2011 Junior


Stuart practises in all areas of intellectual property, including: patents, SPCs, trade marks, passing off, copyright, designs and confidential information. He prides himself on being an approachable and modern commercial advocate who enjoys working as part of a team and with all different types of clients and colleagues.

Despite being of relatively recent call, Stuart already has experience as a junior on the biggest of IP cases. In 2017, he will appear twice in the UK Supreme Court: once in a patents appeal, and then in a trade mark dispute.

Stuart has appeared unled in the Court of Appeal, High Court, the IPEC, the General Court of the European Union, and the European Patent Office, as well as in trade mark registration proceedings (ex parte and inter partes, at first instance and on appeal) in the UKIPO. He enjoys working with solicitors, patent and trade mark attorneys from a variety of different settings, including in-house lawyers, specialists and non-specialists.

Stuart was recognised as a ranked junior in Chambers and Partners (2014 edition) before his first full year as a tenant was complete, and has been ranked each year since. He is also a “leading junior” for intellectual property in the Legal 500.

A chemist by training, he has proven his mettle in cases involving patents and trade marks, and has further won admiration for his advocacy in the IPEC … Extremely hard-working and shows judgment beyond his level of experience … Exceptionally bright and brilliant with clients, he’s going to be a star.”

Chambers & Partners 2016

“An up-and-coming junior whose appearances as sole junior in deeply complex matters belie his recent call … he has also appeared in major trade mark disputes … He’s very bright and doing a lot of big technical cases, ones which would often go to someone of more senior call.”

Chambers & Partners 2015

“Despite only being called in 2011, he is already developing a reputation as a hard-working junior with a confident grasp of the subject … A real star in the making … He is exceptionally bright and brilliant with clients.”
