Calculation of time limits 

Although Rule 131 allows other possibilities, any period fixed by the EPO will usually be specified in full months which will be calculated from the date of notification (see E‑II, 2). Rule 131 gives precise details for the determination of the day of expiry of the period, whilst Rule 134 contains provisions covering certain contingencies (see E‑VIII, 1.6).

When proceedings have been interrupted because of the death of the applicant or proprietor or for any of the other reasons specified in Rule 142 (see E‑VII, 1.1), time limits are subject to the provisions of Rule 142(4). The time limits for the payment of the examination fee and the renewal fees are suspended (see E‑VII, 1.5). The time limits in force at the date of the stay of proceedings under Rule 14 due to national entitlement proceedings, with the exception of those for payment of the renewal fees, are interrupted. Rule 14(4) applies to the calculation of time limits after the resumption of proceedings (see A‑IV, 2.2.4).
