3.8. Time limit for filing a petition for review

In accordance with Art. 112a(4) EPC, a petition for review shall be filed within two months of notification of the decision of the Board of Appeal (or within two months of the date on which the criminal act has been established where applicable).

In R 3/14 the Enlarged Board held that it was essential to observe the two-month time limit expressly prescribed in Art. 112a(4), second sentence, EPC for filing the reasons for the petition and the supporting submissions; no exceptions could be made.

In R 5/14 the Enlarged Board stated that filing a petition and paying the fee before the orally announced decision has been notified to the petitioner in writing did not make it inadmissible under Art. 112a(4) EPC (see also R 20/10).

In R 2/10 the Enlarged Board held that the established jurisprudence of the boards of appeal that mere payment of the appeal fee was not an act which sufficed for the admissible filing of an appeal applied mutatis mutandis to petition for review proceedings.

In R 1/18 the Enlarged Board saw no reason not to apply the findings reached in opinion G 1/18 (OJ 2020, A26) to the provisions governing the legal effects of late payment of the fee for petition for review and so concluded that the petition for review had to be deemed not filed and that the associated fee had to be reimbursed. The Enlarged Board further concluded that the proper legal effect of late payment of the fee for requesting re-establishment of rights was a finding that the request was deemed not to have been filed and that the fee was to be reimbursed (see also T 46/07 in chapter III.E.9. "Reimbursement of the fee for re-establishment").
