In re Schrader, 22 F.3d 290 (Fed. Cir. 1994) is a 1994 decision of the United States Court of Appeals for the Federal Circuit in which the court summarized and synthesized its precedents under the Freeman-Walter-Abele Test of patent eligibility. Under this test a key element is that the claimed invention is implemented with some type of hardware—that is, a particular machine. This was one of the last Federal Circuit decisions using that test.
