ATT v. Excel ruling by US CAFC on 14 April 1999

AT&T Corp. v. Excel Communications Inc.

Cited in ESP's brief for Bilski v. Kappos (2009, USA) as "172 F.3d 1352, 1356-59 (Fed. Cir. 1999)".

This ruling is one of three which Ben Klemens argues wrongly applied the Diehr ruling by using the "as a whole" test without using the "significant post-solution activity" or "transformation" tests.

Thus, the Alappat inquiry simply requires an examination of the contested claims to see if the claimed subject matter as a whole is a disembodied mathematical concept representing nothing more than a "law of nature" or an "abstract idea," or if the mathematical concept has been reduced to some practical application rendering it "useful."
