§2.174 Correction of Office mistake.
Whenever a material mistake in a registration, incurred through the fault of the United States Patent and Trademark Office, is clearly disclosed by the records of the Office, a certificate of correction stating the fact and nature of the mistake, signed by the Director or by an employee designated by the Director, shall be issued without charge and recorded. A printed copy of the certificate of correction shall be attached to each printed copy of the registration certificate. 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.
