A well-defined § 101 ensures that abstract software patent claims and their attendant notice and patent thicket problems do not undermine the patent system and stymie innovation. It serves as a decisive gatekeeper that the Patent Office and trial courts can use early in administrative proceedings and litigation. Further, it avoids many of the systemic challenges prevalent with the use of §§ 102, 103, and 112 in such cases—the speed of software innovation, the difficulty locating software prior art, and lax, broad claiming standards. Accordingly, this Court should affirm the invalidity of patent claims at issue here and hold that abstract ideas in the form of software are unpatentable and that mere computer implementation of those ideas does not create patentability.
