Jason Raeburn is a Partner in the London office of Paul Hastings and heads up our London intellectual property and technology litigation practice.

Jason's practice has a particular focus on complex technology disputes, often relating to trade secrets, patents and copyright in the fields of software development and licensing, cloud, life sciences, and AI-related implementations. His practice also encompasses IP crossover issues involving breach of contract, contractual interpretation, IT infrastructure, the misuse of data, and reputational threats.

Mr. Raeburn sits part-time as a judge in the English High Court, as a Deputy Master of the Chancery Division, and as a Judge of the First-Tier Tribunal, hearing specialist appeals.

He is the General Editor of "The Civil Court Practice" (the "Green Book") – the indispensable authority on jurisdiction and procedure in the civil courts of England & Wales for practitioners, judiciary and litigants in person.

Clients comment that his "litigation expertise is exceptional" and his "advice is always considered and pragmatic", that he is "always a pleasure to deal with and very responsive" – Legal 500 (2022), that he has "a tremendous depth of knowledge in IP and technology law", has an "ability to master complex situations, advise calmly – both across legal and the business", and is an "absolute star".

Jason was recognised by Who's Who Legal as a "Future Leader" in Litigation (2020, 2021) having been identified as one of "the most promising litigators in the world, whose skills and expertise are already turning heads at an international level". Legal 500 describes him as "one to watch" as a next generation partner, a "stand out name" for TMT and a key lawyer for intellectual property and high value IT and software disputes.
