Designation fee 

The time limit for paying the designation fee is 31 months from the date of filing or, if priority has been claimed, from the earliest priority date (31-month time limit), if the time limit specified in Rule 39(1) has expired earlier (Rule 159(1)(d)) (see A‑III, 11.2.5 for further details). If, subsequent to the receipt of the international application by the EPO and prior to the date on which processing or examination may start, the regional designation of all contracting states of the EPC is withdrawn, the Euro-PCT application, in so far as it is deemed to be a European application pursuant to Art. 153(2) and Art. 11(3) PCT, is deemed to be withdrawn.

For information on the requirements for extension or validation of a Euro-PCT application to states for which an Extension Agreement or a Validation Agreement with the EPO has become effective, see A‑III, 12.
