IP Litigation

Our IP litigation and legal department advises on all aspects of IP law. Our experience and expertise ranges from dealing with small IP disputes (often resolved in negotiation), to hard-fought high-value IP litigation and coordinating parallel actions in other jurisdictions.

The A.A. Thornton & Co. litigation approach is, where appropriate, for IP solicitors to work closely with our patent or trade mark attorneys to provide a coordinated approach to both enforcement and protection – ensuring the best possible resolution of IP disputes. The strength of our collective technical expertise also ensures that we can understand the necessary complexities involved in each case.

We have individuals with extensive experience representing clients in disputes relating to patents, trade marks, copyright, design right, breach of confidence and licences, at the UK Patents Court and the Court of Appeal as well as in oppositions and other contentious hearings at the EPO, EUIPO and UKIPO.
