Filing a European patent application

To pursue patent protection in Europe, you typically file a single European patent application with the EPO. This application, by default, designates all of the European contracting states.

Please note: You can file your European patent application via the PCT process, and can help.

After filing, your European patent application is examined by the EPO. Your European attorney will then exchange correspondence with the EPO until any objections have been resolved.

Validating a European patent

Once the European examiner’s objections have been resolved, the EPO will issue a Notice of Intention to Grant (also referred to as a 71(3) notice). This gives your European attorney four months to lodge a translation of your claims into English, French and German, and pay printing and grant fees to the EPO.

Once this is complete, the EPO will grant your patent. The formal Decision to Grant your European patent is published in the European Patent Bulletin. You have three months from that publication date to validate your patent in the individual European countries where you want protection.

It’s important to note that your European patent will only extend to those countries in which you choose to validate the patent. The rights will lapse in any countries where you don’t validate.

What is validation?

The exact process of validation differs in each country, but generally involves paying a fee and (where necessary) lodging a translation of either the claims or the entire patent specification. It is also usual to record a local address for service in the individual countries.

Each European contracting state has its own requirements for validation. For further country-specific details, please browse our filing guide.

Once validated, you do not need to go through any further prosecution in the individual European countries. Your patent will remain active as long as you continue to pay the yearly annuities.
