Litigation in the UK
When it comes to enforcing patents or defending patent infringement claims, the stakes are high. The right litigation strategy can determine whether a business protects its market position or loses ground to its competitors.
Our expert team understands that litigation is not just about legal arguments, it’s about business outcomes.
The stellar reputation that the UK's specialist IP courts hold stems from their vast experience of handling IP disputes, their well-established procedural rules and the quality of their judges. Their decisions are clear and reasoned, influential and respected around the world.
We regularly act for both patentees and defendants, including standard essential patent (SEP) holders in FRAND disputes, and handle actions before the Intellectual Property Enterprise Court, Patents Court, Court of Appeal of England & Wales and UK Supreme Court, as well as the Unified Patent Court (UPC).We are experts in navigating the idiosyncrasies of UK patent litigation, including the disclosure of documents and the preparation of technical expert evidence. EIP is also well placed to act in arbitration, particularly in relation to the determination of FRAND rates and contractual terms.
Our UK litigation practice is ranked in JUVE, IAM Patent 1000, Legal 500, Chambers & Partners, IP Stars and WIPR. We are recognized for our technical depth and strategic approach.
Based in London, our lawyers are vastly experienced in high-value patent disputes, including in the electronics, telecoms, video codecs, engineering, life sciences, pharmaceuticals, chemical and medtech fields.
“EIP has one of the best patent litigation teams in the country. They are resilient, insightful and determined. They always pursue their client's commercial goals in a determined, focused and resourceful way.”
Case Study
How Optis won a landmark $700M FRAND licence against Apple in the UK
We worked with Optis to secure a landmark victory in its patent dispute with Apple, winning a FRAND licence worth over $700 million—the largest such award ever set by a UK court. The Court of Appeal’s decision not only increased the original award tenfold but also set a new benchmark for how UK courts value telecoms patents and handle multi-jurisdictional disputes.
This result re-establishes the UK as a balanced forum for Standard Essential Patent holders and will influence future global licensing negotiations. Our deep expertise and strategic approach delivered a commercially realistic outcome for the client, attracting widespread industry attention and recognition.
