European patent validation

£ 0.00 (+VAT and Card Processing Fees)

Once a European patent has been granted by the EPO, it is necessary to convert it into a national patent in the countries of your choosing.  The requirements vary from country to country, but they generally involve appointing a local agent to represent you, paying an official fee, and filing translations of the claims or the entire specification in the official language of the country concerned.

To use this service, we will need:

  • The European patent (grant) number
  • The European application (pre-grant) number;
  • The name of the applicant (owner) as it appears on the EPO’s register; and
  • Of course, the countries in which you want to validate the patent.
