My address has changed. How can I inform the EPO?

Requests to register a change of address for the applicant or patent proprietor must be submitted to the EPO in writing, quoting the application or patent number(s) concerned. Where appropriate, you can indicate that the change of address affects all the applications/patents belonging to the applicant/patent proprietor. In that case, you do not have to submit a list of the individual applications/patents concerned. The request must simply state that the change of address relates to all the applications/patents owned by the applicant/proprietor.

We recommend that you use EPO Form F5051.

There is no fee payable.

A change of address can be registered in the European Patent Register as long as proceedings are pending before the EPO, and until expiry of the opposition period (see Article 99(1) EPC).
