European Patent Application (EP Application)

The European patent is granted by the European Patent Office (EPO) and has the same effect, in the member states of the European Patent Organization (EPO) in accordance with the European Patent Convention (EPC), as a national patent. European Patent Convention (EPC) member countries (January, 2003) are: Austria, Belgium, Bulgaria, Czech Republic, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, Monaco, Netherlands, Portugal, Slovakia, Slovenia, Spain, Slovakia, Sweden, Switzerland (incl. Liechtenstein), Turkey, United Kingdom. Albania, Lithuania, Latvia, former Yugoslav Republic of Macedonia, Romania can also be added as Extension States. The main advantage of the European patent system is that only one proceeding is required to obtain a patent in almost all the European countries.
