“An idea without a physical embodiment"

From within Ex parte Harper

A claim that recites no more than an abstraction does not fall within
any statutory category. In re Warmerdam, 33 F.3d 1354, 1361 (Fed. Cir.
1994). Significantly, we find claim 84 to be merely “an idea without
physical embodiment.” Microsoft Corp. v. AT&T Corp., 550 U.S. 437, 449
(2007).

Appellants lose at Board.
