Stuart Baran

Called to the bar 2011 Junior


Stuart was Legal 500 Junior of the Year: IP, IT and Media for 2018. In 2019 he was appointed to a three-year term as one of two Standing Counsel to HM Comptroller-General of Patents, Designs and Trade Marks.

He 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. He was sole junior to Eli Lilly in its celebrated multi-national battle against Actavis that culminated before the UK Supreme Court with a judgment that defines the modern approach to patents construction. He also appeared before the CJEU in Luxembourg on the ground-breaking Sky v. SkyKick (trade marks) and Sandoz v. Searle (SPCs) cases.

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. In 2017/18 he was awarded “2018 Junior of the Year: IP, IT and Media” by Legal 500, and nominated for the equivalent award from Chambers & Partners.
