Is there a fee for requesting a Certificate of Correction for an Office mistake?
No, there is no fee for requesting a Certificate of Correction for an Office mistake. According to MPEP 1480, which cites 35 U.S.C. 254:
“Whenever a mistake in a patent, incurred through the fault of the Patent and Trademark Office, is clearly disclosed by the records of the Office, the Director may issue a certificate of correction stating the fact and nature of such mistake, under seal, without charge, to be recorded in the records of patents.”
Additionally, for minor errors that do not require a formal Certificate of Correction, the MPEP states: “There is no fee for the submission of such a letter.” This refers to letters making errors of record for minor typographical mistakes.
