One of the major novelties introduced by the EPC 2000 is the central limitation proceedings (Articles 105(a), 205(c) and Rules 90-96), according to which the patent owner can request the central limitation of a granted European patent. According to the intention of the EPO, this should be a very quick administrative procedure. From the viewpoint of the national practitioner, the duration of the proceedings are especially interesting with respect to pending national revocation and/or infringement actions.
