# §1.780. Certificate or order of extension of patent term.


If a determination is made pursuant to [§ 1.750](/cfr/37/1.750.md) that a patent is eligible for extension and that the term of the patent is to be extended, a certificate of extension, under seal, or an order granting interim extension under [35 U.S.C. 156(d)(5)](/usc/35/156.md?p=d-5), will be issued to the applicant for the extension of the patent term. Such certificate or order will be recorded in the official file of the patent and will be considered as part of the original patent. Notification of the issuance of the certificate or order of extension will be published in the Official Gazette of the United States Patent and Trademark Office. Notification of the issuance of the order granting an interim extension under [35 U.S.C. 156(d)(5)](/usc/35/156.md?p=d-5), including the identity of the product currently under regulatory review, will be published in the Official Gazette of the United States Patent and Trademark Office and in the Federal Register. No certificate of, or order granting, an extension will be issued if the term of the patent cannot be extended, even though the patent is otherwise determined to be eligible for extension. In such situations, the final determination made pursuant to [§ 1.750](/cfr/37/1.750.md) will indicate that no certificate or order will issue.
