As of 2023 the European Patent Office jurisdiction incorporates 44 countries and 39 member states.  We have the technical and professional armoury, as well as the pan-European experience, to ensure you are properly represented, with a holistic approach to protecting your portfolio across multiple territories – often as part of a global strategy.

Our highly-experienced patent attorneys are fully qualified to act as your professional representatives in proceedings before the European Patent Office.

Our European Patent Office representation services cover:

  • Drafting, filing and prosecution
  • Grant and validation proceedings
  • Opposition proceedings
  • Regional phases of PCT and EuroPCT applications
  • Appeal proceedings
  • IP portfolio management (including renewals, opinions and search & watch services)

‘I could tell you my adventures–beginning from this morning,’ said Alice a little timidly: ‘but it’s no use going back to yesterday, because I was a different person then.’
