Chambers of Iain Purvis QC
11 South Square


11 South Square is a leading set, specialising in intellectual property law, additionally well-known for its media and information technology work. With many recent cases setting precedents in all areas of IP law, 11 South Square has continued to be highly regarded in the field. Members are often singled out for the excellent quality of advice and advocacy provided.

The set: 11 South Square was founded in 1923 by Sir Stafford Cripps. Chambers currently has 16 members, five of whom are Queen’s Counsel, headed by Iain Purvis QC. In 2015 Henry Carr was appointed as a High Court judge sitting in the Patents Court. He joins the long list of former members recently called to the Bench including current Patents Court judge Mr Justice Arnold, presiding judge of the Intellectual Property Enterprise Court Richard Hacon, current Court of Appeal judge Lord Justice Floyd, as well as the late Lord Justice Pumfrey.

Types of work undertaken: Members of 11 South Square regularly appear before the Supreme Court, the Court of Appeal and the High Court as well as the Intellectual Property Enterprise Court and the UK Intellectual Property Office. In addition, barristers from 11 South Square have appeared before the European Patent Office in Munich and also the General Court and the Court of Justice of the European Union.

Representation and advice in patent matters is an important part of chambers’ work. The command and conduct of such cases requires a thorough understanding of the science and technology involved. Due to their technical expertise, many members act in complex computer software and IT disputes.

11 South Square has been involved in many of the recent important cases in the areas of performers’ rights, copyright, trade marks, confidential information and also the developing law of privacy, personality and celebrity endorsement. The creation of an unregistered design right and database right has greatly expanded the work in this area, with members frequently appearing in leading cases.

Some members have particular expertise in disputes which involve the Data Protection Act and have appeared extensively in cases before the Information Tribunal.
