1.4 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 of how the day of expiry of the period is to be determined, whilst Rule 134 covers 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 governed by Rule 142(4). The time limits for paying the examination fee and the renewal fees are suspended (see E‑VII, 1.5). Any time limits already running on the date proceedings are stayed under Rule 14 due to national entitlement proceedings are interrupted, except for those for paying the renewal fees. Rule 14(4) applies to the calculation of time limits after proceedings have been resumed (see A‑IV, 2.2.4).
