Our team of market leading attorneys and specialist IP lawyers have the combined technical and commercial expertise to proactively challenge and cancel third-party rights.

The opposition procedure before the European Patent Office can provide a cost-effective route to revoke a European patent centrally. However, if the opportunity for opposition has passed, or if speed is of the essence, we have the expertise and the network of contacts to revoke third-party rights nationally.

Registered trade marks or designs can also be invalidated or revoked centrally at the EU Intellectual Property Office for European rights, or nationally for national rights.

Our team can help you:

  • Assess the validity of a third-party patent, and provide an infringement opinion to determine whether revocation is necessary
  • Devise a strategy to determine the best forum for a revocation action – for example, determining the best jurisdiction in Europe to commence proceedings, or, for a UK right, deciding whether the Patents Court, the Intellectual Property Enterprise Court (IPEC) or the Intellectual Property Office is the appropriate forum
  • Invalidate or revoke a registered trade mark or design
  • Find a cost-effective strategy that meets your business goals
