European Patent Office

Supporting innovation for the benefit of Europe’s citizens

As the Patent Office for Europe, we support innovation, competitiveness and economic growth across Europe through a commitment to high quality and efficient services delivered under the European Patent Convention.

The Office's  task is to grant European patents for inventions on the basis of a centralized procedure for the contracting states to the European Patent Convention (EPC), which was signed in Munich on 5 October 1973 and entered into force on 7 October 1977.

The EPO is the executive arm of the European Patent Organisation, an intergovernmental body set up under the EPC, whose members are the EPC contracting states. The activities of the Office are supervised by the Organisation's Administrative Council, which is composed of the delegates from the contracting states. The EPO has its headquarters in Munich, a branch at The Hague and offices in Berlin and Vienna. With its workforce of almost 7 000 staff, the EPO is one of the largest European institutions.

The EPC states currently are Albania, Austria, Belgium, Bulgaria, Switzerland, Croatia, Cyprus, the Czech Republic, Germany, Denmark, Estonia, Spain, Finland, France, United Kingdom, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, the Former Yugoslav Republic of Macedonia, Malta, Monaco, The Netherlands, Norway, Poland, Portugal, Romania, San Marino, Serbia, Slovenia, the Slovak Republic, Sweden and Turkey. European patent applications and patents can also be extended at the applicant's request to Bosnia and Herzegovina and Montenegro. European patents reach a market of about 600 million inhabitants.

The EPO was set up with the aim of strengthening co-operation between the countries of Europe in the protection of inventions. This was achieved by adopting the EPC, which makes it possible to obtain patent protection in several or all of the contracting states by filing a single patent application in one of the three official languages of the EPO (English, French and German). The EPC also establishes standard rules governing the treatment of patents granted under this procedure.
