EPO general info

The procedure for obtaining a European Patent is regulated under the European Patent Convention (EPC).

The European regional patent application is filed to the European Patent Office (EPO).

The European patent is valid automatically on the territory of BelgiumGermany, FranceSwitzerland, Liechtenstein, Monaco, IrelandLuxembourg, and the United Kingdom. It is necessary to conduct the procedure of validation if the applicant wishes to obtain a patent protection in other European Convention member states. Validation is a process of filing the corresponding request to the designated country, providing the translation into the national language, and payment of the maintenance fees.
