For a number of years now European patent law has provided the holder of a European patent with the option of centrally limiting or revoking his/her patent. This has the advantage that it need not be done separately for each national patent-granting authority. The patent holder also has complete control over the limitations to his/her patent. This is different from a revocation action or an opposition procedure in which a third party can put forward arguments and evidence in order to have the patent (partially) revoked.
