Regardless of what statutory category (“process, machine, manufacture, or composition of matter,” 35 U.S.C. § 101) a claim’s language is crafted to literally invoke, we look to the underlying invention for patent-eligibility purposes. Here, it is clear that the invention underlying both claims 2 and 3 is a method for detecting credit card fraud, not a manufacture for storing computer-readable information. This case is thus similar to In re Abele, 684 F.2d 902 (CCPA 1982). In Abele, claim 5 of the patent at issue recited “[a] method of displaying data” comprising the steps of “calculating the difference” between two numbers and “displaying the value.” Id. at 908. The court concluded that claim 5 was not directed to patent eligible subject matter because it claimed an abstract idea. Id. However, claim 7 was argued to be different because it recited an “[a]pparatus for displaying data” comprising “means for calculating the differences” between two numbers and “means for displaying the value.” Id. at 909 (emphases added). Though claim 7 literally invoked an “[a]pparatus,” the court treated it as a method claim for the purpose of its § 101 analysis. Due to its “broad” and “functionally-defined” nature, the court found that treating claim 7 as an apparatus claim would “exalt form over substance since the claim is really to the method or series of functions itself.” Id. (citation omitted). Accordingly, the court placed “the burden . . . on the applicant to demonstrate that the claims [were] truly drawn to [a] specific apparatus distinct from other apparatus[es] capable of performing the identical functions.” Id. (citation omitted).

In the present case, CyberSource has not met its burden to demonstrate that claim 2 is “truly drawn to a specific” computer readable medium, rather than to the underlying method of credit card fraud detection. To be sure, after Abele, we have held that, as a general matter, programming a general purpose computer to perform an algorithm “creates a new machine, because a general purpose computer in effect becomes a special purpose computer once it is programmed to perform particular functions pursuant to instructions from program software.” In re Alappat, 33 F.3d 1526, 1545 (Fed. Cir. 1994). But we have never suggested that simply reciting the use of a computer to execute an algorithm that can be performed entirely in the human mind falls within the Alappat rule. Thus, despite its Beauregard claim format, under Abele, we treat claim 2 as a process claim for patent-eligibility purposes.
