annual fees after grant

The validity of the European patent is 20 years maximum, upon condition however that the annual maintenance fees are paid each year on the anniversary of the filing date. These fees are due at the EPO before grant, and at the different national offices of the designated states after grant. It is possible to pursue or to abandon the patent separately in the different states and the European patent can also be invalidated separately in each state by the national courts.
