European patent applications

If you need to protect your invention in Europe, you can file a European patent application (EP application). This application allows you to obtain protection in some or all of more than 30 contracting states of the European Patent Office (EPO).

After grant, a European patent has to be validated in the individual, designated contracting states to become effective. Validation requirements differ between the individual states but typically involve the filing of a translation of the patent specification and/or the patent claims with the national patent offices. Some states also demand the payment of a validation fee for the European patent to take effect.
