Where the priority is claimed pursuant to Paragraph 1, Article 30 of the Act, in the event the certificate fee and the first-year annuity with respect to the earlier patent application is paid pursuant to the Act, either at the same time, prior to or after the claiming of priority, the Specific Patent Agency shall notify the applicant to withdraw within the specified time period either the priority claim of the subsequent patent application or the request for patent certificate of the earlier patent application. If a withdrawal has not been made within the specified time period, the earlier patent application shall not be published and the Specific Patent Agency shall notify the applicant that the certificate fee and the first-year annuity may be refunded by request.
