If, on examination, PVPO determines that the applicant is entitled to a certificate, a notice of allowance shall be sent to the applicant or his or her attorney or agent of record, if any, requesting verification of the variety name and of the name of the owner. The notice will also provide an opportunity for withdrawal of the application before certificate issuance. The applicant must respond within 30 days from the date of the notice of allowance. Thereafter, a fee for delayed response shall be charged as specified in § 97.175(f).
