The one-year period is not an alternative to the two-month period; a request has to be filed within two months of the removal of the cause of non-compliance, and no request can be filed more than one year after expiry of the unobserved time limit (J 11/17).

The two-month time limit also applies if the time limits under Art. 102(4) and (5) EPC 1973 have been missed, even if no decision has yet been handed down concerning revocation (G 1/90, OJ 1991, 275). The omitted act must be completed within the same period. The fee for re-establishment of rights is also payable within the same time limit as that stipulated by Art. 122(2) EPC 1973 for the filing of an application for re-establishment (J 18/03).
