Under the applicable national provisions of the extension and validation states, the extension or validation fee must be paid
(ii)for Euro-PCT applications, within the period for performing the acts required for entry of an international application into the European phase, or within six months of the date of publication of the international search report, whichever is the later.
If the fee for an extension or validation state has not been paid within the corresponding basic period (see items (i) and (ii) above), the applicant can still pay the extension or validation fee together with a 50% surcharge
(b)if the designation fee has not been paid, along with the filing of a valid request for further processing concerning the designation fee, within two months of notification of a communication of loss of rights with regard to the designation fee (see the notices from the EPO dated 2 November 2009, OJ EPO 2009, 603, and 5 February 2015, OJ EPO 2015, A19).
If the applicant fails to pay the extension or validation fee during the basic and the grace period, the request for extension or validation is deemed to be withdrawn. No communication of loss of rights is issued.
However, a noting of loss of rights related to the failure to pay the designation fee pursuant to Rule 39(2) or Rule 159(1)(d) will draw the applicant's attention to the lack of payment of the extension or validation fee, where appropriate, triggering the time limit mentioned in item (b) above.
