Patent Litigation
Patent Litigation
We are trial lawyers. We work hard to protect our clients’ legal rights and to achieve the most advantageous outcomes.
We have been engaged in many important patent cases across a wide range of industries (e.g., life sciences, energy, manufacturing, telecommunications and technology) and are very proud of our record of success.
We are particularly well-known for our work on behalf of innovative pharmaceutical and biotechnology companies in patent infringement, validity and section 8 damages actions under the Patented Medicines (Notice of Compliance) Regulations.
We are respected by our peers for our knowledge of the law, our preparation, our professionalism, and our zealous advocacy.
