An interruption is registered (in general retroactively) with legal effect from the date of the occurrence of the event. In cases where proceedings are interrupted on request, the interruption is effected as from the date of receipt of the request at the EPO.

The parties are informed of the interruption of proceedings and the reasons for it. The date of interruption as well as the date of resumption of proceedings are recorded in the European Patent Register.[Rule 143(1)(t); ]
