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 state in the request 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.
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).
There is no fee payable.
Supporting evidence is needed in certain cases:
A legal entity changes their address to a different country;
A natural person changes their address to a different country where the former country was not an EPC contracting state and the new country is an EPC contracting state.
Any kind of evidence is acceptable, e.g. a copy of a rental contract, utility bill, "Meldebescheinigung" in Germany.
We recommend that you use EPO Form 5051 or request the change via MyEPO Portfolio (see MyEPO Portfolio Feature guide, point 3.2). Please note that the option to submit bulk requests in respect of bibliographic data is not available in MyEPO Portfolio.
