AT&T Corp. v. Excel Communications, Inc., 172 F.3d 1352 (1999) [1] was a case in which the United States Court of Appeals for the Federal Circuit reversed the decision of the United States District Court for the District of Delaware, which had granted summary judgment to Excel Communications, Inc. and decided that AT&T Corp. had failed to claim statutory subject matter with U.S. Patent No. 5,333,184 (the '184 patent) [2] under 35 U.S.C. § 101. The United States Court of Appeals for the Federal Circuit remanded the case for further proceedings.
