Three New Square is a set of barristers’ chambers specialising in intellectual property law which has been established for over seventy years and currently comprises twenty-two tenants, eight of whom practise as Queen’s Counsel.

The core of the work undertaken in chambers involves patents, registered trade marks, passing off, copyright, registered designs, design rights, confidential information and trade secrets. In addition, work carried out in chambers can involve information technology, computer contracts, media and entertainment law, scientifically complex litigation, arbitration, franchising, plant breeders’ rights, performing rights, semi-conductor topography rights, moral rights, and related areas of European and UK competition law.


Chambers’ clerks’ room is currently staffed by a reduced number of members of staff between 9am and 6pm, with the remainder working remotely.  Our  phonelines are staffed between 8am and 7pm.

Members of chambers remain working remotely for the most part, although it is hoped that there will be a gradual return to chambers as and when the current restrictions are lifted and in person court hearing re-commence.
