Certificate of correction of applicant’s mistake

§ 255. Certificate of correction of applicant’s mistake Whenever a mistake of a clerical or typographical nature, or of minor character, which was not the fault of the Patent Office, appears in a patent and a showing has been made that such mistake occurred in good faith, the Commissioner may, upon payment of the required fee, issue a certificate of correction, if the correction does not involve such changes in the patent as would constitute new matter or would require reexamination. Such patent, together with the certificate, shall have the same effect and operation in law on the trial of actions66 Stat. 810 for causes thereafter arising as if the same had been originally issued in such corrected form.
