1Opinion of the Court
RICH, Circuit Judge.
This appeal is from the decision of the United States Patent and Trademark Office (PTO) Board of Patent Appeals and Interferences (board), dated May 24, 1988, adhered to on reconsideration, affirming the examiner’s final rejection of the single claim of applicants’ patent application serial No. 454,022, filed December 28, 1982, entitled “Auto-Correlation Circuit for Use in Pattern Recognition.” The sole ground of rejection is that the subject matter claimed is nonstatutory under 35 U.S.C. § 101 because it is merely a mathematical algorithm. We reverse.
