Patent Litigation

Rely on our patent litigation lawyers to assess risk, set the right strategy for your business, and strive to get you the best possible outcome.

The very nature of an intellectual property strategy  for your technology leaves you open to the possibility of infringements of your IP and the need to defend it. When all other ADR routes have been exhausted, you can depend on the commercial acumen of our patent litigation lawyers to get you the most cost-effective result.

How we can help: Pre-litigation strategy and effective negotiations

Our intellectual property solicitors can support you with advice on all aspects of patent litigation such as:

  • Pre-action procedures and settlement negotiations.
  • Assessing risk of revocation of the patent before proceeding with litigation.
  • Patent litigation strategy to support businesses in filing claims, considering the available evidence, demonstrating the validity of the patent, and the likely costs involved in pursuing settlement.
  • Requests for a non-binding opinion from the Intellectual Property Office (IPO) on the issue of infringement or the validity of a patent to help you decide whether to commence proceedings.
  • Enforcement of patents against third parties.
  • Defending organisations against patent infringement claims.
  • Securing any relief or remedies that may be available.
  • Advice on the points in your IP lifecycle which may trigger disputes, so we can remain prepared for oppositions, and poised for litigation and appeals.
  • Efficient litigation in both the IPEC and the Patents Court – with established working relationships with the UK IPO and the European Patent Office we will also ensure your matter is managed effectively.
  • Seeking interim injunctions in addition to damages so that the ongoing patent infringement will cease until a decision is made at trial.
  • Careful management of complex patent disputes and litigation spanning across multiple jurisdictions.
  • Appeals and challenging the IPO, for example, where the patent specification has been wrongly interpreted, providing arguments, or amending the patent to address issues and avoid revocation.
  • Up-to-date knowledge of the Unified Patents Court and any changes you need to be aware of due to Brexit.
