Introduction 

The limitation and revocation procedures are centralised ex parte procedures at the level of the EPO which allow the patent proprietor either to have the claims of his granted patent limited or to have the whole patent revoked for all the designated states. More particularly, the limitation procedure offers an opportunity to obtain a limitation of a European patent in a short and straightforward procedure.

Unlike in the opposition procedure, there is no restriction on the period between the grant of the patent and the filing of the request. Accordingly, the request can be filed at any time after grant, after opposition proceedings, or even after expiry of the patent.

Certain aspects of this procedure are entrusted to formalities officers (see the Decision of the President of the EPO dated 12 July 2007, Special edition No. 3, OJ EPO 2007, F.2, as amended; consolidated version reprinted in Special edition No. 1, OJ EPO 2010, D.1).
