Article 8
Insufficiency of the amount paid
(1) A time limit for payment shall in principle be deemed to have been observed only if the full amount of the fee has been paid in due time. If the fee is not paid in full, the amount which has been paid shall be refunded after the period for payment has expired. The Office may, however, in so far as this is possible within the time remaining before the end of the period, give the person making the payment the opportunity to pay the amount lacking. It may also, where this is considered justified, overlook any small amounts lacking without prejudice to the rights of the person making the payment.
(2) Where the amount paid in designation fees is insufficient to cover the designation fees payable for all the Contracting States, the amount paid shall be applied according to the specifications to be made by the applicant by the time of payment at the latest. If the applicant makes no such specifications, the fees shall be deemed to be paid only for as many designations as are covered by the amount paid and in the order in which the Contracting States are listed in the request for grant.
