8 New Square Intellectual Property

8 NEW SQUARE is the largest specialist intellectual property chambers in the United Kingdom. Chambers has 32 IP Barristers, including 12 KCs. We have two former Judges as door tenants as well as two active Judges sitting in the High Court. 8 New Square’s depth of knowledge and breadth of experience in intellectual property, media and entertainment and IT law is second to none. Chambers is involved in a significant proportion of all IP related trials each year, with members appearing in the majority of recent landmark cases before the Supreme Court, Court of Appeal and specialised patent division of the High Court.

From our most senior silks to our most junior members, we can offer technical and scientific expertise over a wide variety of disciplines. Many members of chambers have graduate or post-graduate level scientific qualifications and/or technical industrial experience. Chambers also offers a commercially focused service. We have market-leading experience in dealing with IP issues for large multinational commercial organisations, small to medium-size businesses, government departments and universities as well as individual inventors, artists and musicians. We value our friendly and approachable style and we are committed to achieving the best for our clients.

The set:  Members of chambers are at the forefront of intellectual property litigation; advising on and presenting cases with considerable technical detail. Most have at least an undergraduate science qualification and some have advanced science degrees. Chambers handles litigation for leading commercial organisations around the world and high-profile individuals, as well as small companies and individuals. Members appear in the major English courts and tribunals including the High Court, Court of Appeal, Supreme Court and The Intellectual Property Office including trade marks and design registries, as well as in cases before the Copyright Tribunal and the Intellectual Property Enterprise Court. Several members have written leading textbooks on aspects of intellectual property. The Reports of Patent Cases and The Fleet Street Reports, the two main specialist intellectual property law reports, have been edited from these chambers for many years, as well as the most recent editions of Kerly on Trade Marks and Trade Names, The Modern Law of Copyright and Designs and Russell-Clarke and Howe on Industrial Designs.

International:  Not only do members act in the major European courts, they also act in domestic and international arbitrations and mediations. Some are qualified to practice and appear in various courts overseas, including the Far East and the West Indies.

Types of work undertaken:  Patents expertise covers every field of technology. Members act in cases concerning the validity, infringement and licensing of patents and know-how, including competition aspects. A team from chambers acted in the first ever biotechnology patent appeal to reach what is now known as the Supreme Court and a total of five counsel appeared before the same court in the first FRAND rate determination dispute of Unwired Planet v Huawei. Chamber’s expertise and quality in FRAND licensing disputes has again been demonstrated this year with the Court of Appeal decisions in Lenovo v Ericsson  and Optis v Apple as well as the High Court hearings in MediaTek v Huawei, Samsung v ZTE and Acer, Asus & Hisense v Nokia.

8 New Square’s continued run of appearing in the major IP cases of the Supreme Court saw members of chambers in 2025 represent the respondent’s in the matter of Emotional Perception AI v Comptroller-General for Patents

Other noteworthy patent cases of the last 12 months include DSM IP Assets v Mara Renewables, Merck KGaA v Merck Sharp & Dhome, Alexion v Samsung and Amgen, Moderna v Pfizer & BioNTech and Formycon and Samsung v Regeneron and Bayer.

All members of chambers have wide experience in trade mark infringement, validity and passing-off litigation as well as disputes concerning ownership of trade marks.

Breach of confidence is also an area of expertise, with members of chambers involved in major employer/employee disputes.

Privacy and media & entertainment related disputes form a large part of chambers’ work. Cases have involved leading companies and prominent individuals. Work in this area covers film, music and other related media contracts, publishing and broadcasting disputes, and performers’ rights. The matter of AFM & SAG-AFTRA v Sec of state for Science Innovation & Technology sees two members of chambers represent the rights of performers in the music industry to “equitable remuneration” when sound recordings are broadcast in the UK in an upcoming trial & Judicial Review.

Tyburn Film Productions v Broughton & Ors, The Duchess of Sussex v Associated Newspapers, Sheeran v Chokri and Shazam v Only Fools The Dining Experience are all further cases of recent significance.

Information technology is another major area of chambers’ practice which has included appearances at the Supreme Court – most notably the Cartier International v British Sky Broadcasting Ltd action. This area of expertise includes contractual disputes before the Technology and Construction Court, advice on internet and domain names database rights and data protection. Of particular media & public interest over the last 12 months, 8 New Square had several counsel (acting for both sides) in the trial of Getty Images (US) Inc v Stability AI Ltd – the first case in the UK to deal with the application of IP Law to AI models.
