European Patent Office

The European Patent Office (EPO) offers inventors a uniform application procedure which enables them to seek patent protection in up to 40 European countries. Supervised by the Administrative Council, the Office is the executive arm of the European Patent Organisation.


The Office is also responsible for examining oppositions filed against granted European patents.


The boards of appeal are responsible for deciding on appeals filed against decisions of the receiving, examining and opposition divisions of the EPO. They also consider alleged breaches of the Rules of Professional Conduct for professional representatives before the Office. The boards of appeal are independent, their decisions being governed solely by the provisions of the European Patent Convention. Read more about the boards of appeal .
