What is the EPO?

The European Patent Office examines European patent applications, enabling inventors, researchers and companies from around the world to obtain protection for their inventions in up to 44 countries through a centralised and uniform procedure that requires just one application.


Over the past 45 years, the EPO has increased the number of members from only seven founding states in 1977 to 39 member states as of 1 October 2022. The EPO highlights how this growth is “a success story of international co-operation and European integration, by helping steer innovation and economic growth.”
