The Court held that because the claim was not limited to any particular type of programmable digital computer and neither involved special purpose implementing machinery nor a transformation of substances, as in all prior cases holding processes patentable, the claim would effectively preclude use of

35 U.S.C. 101 says, "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof may obtain a patent therefor, subject to the conditions and requirements of this title." 35 U.S.C. 100(b) gives the definition for
