In re Arnott

A certificate of correction under 35 U.S.C. 255 requires that the mistake be of a clerical nature, typographical nature, or minor character, and that the correction neither constitute new matter nor require reexamination; a clerical or typographical mistake ordinarily must be manifest from the contents of the patent file.
