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-one 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.

3 New Square remains open for business during the Christmas and New Year period. Our current working practice is that premises are staffed between 9am and 6pm on weekdays, and phonelines are staffed between 8am and 7pm. Over the Christmas vacation period the following adjustments will apply:
