Code of Federal Regulations Title 37. Patents, Trademarks, and Copyrights § 37.2.174 Correction of Office mistake

Whenever Office records clearly disclose a material mistake in a registration, incurred through the fault of the Office, the Office will issue a certificate of correction stating the fact and nature of the mistake, signed by the Director or by an employee designated by the Director, without charge. Thereafter, the corrected certificate shall have the same effect as if it had been originally issued in the corrected form. In the discretion of the Director, the Office may issue a new certificate of registration without charge.
