The subject matter of claims permitted within 35 U.S.C. § 101 must be a machine, a manufacture, a process, or a composition of matter. Moreover, our reviewing court has stated that “[t]he four categories [of § 101] together describe the exclusive reach of patentable subject matter. If the claim covers material not found in any of the four statutory categories, that claim falls outside the plainly expressed scope of § 101 even if the subject matter is otherwise new and useful.” In re Nuijten, 500 F.3d 1346, 1354 (Fed. Cir. 2007); accord In re Ferguson, 558 F.3d 1359 (Fed. Cir. 2009). This latter case held that claims directed to a “paradigm” are nonstatutory under 35 U.S.C. § 101 as representing an abstract idea. Thus, a “signal” cannot be patentable subject matter because it is not within any of the four categories. In re Nuijten, 500 F.3d at 1357. Laws of nature, abstract ideas, and natural phenomena are excluded from patent protection. Diamond v. Diehr, 450 U.S. at 185. A claim that recites no more than software, logic or a data structure (i.e., an abstraction) does not fall within any statutory category. In re Warmerdam, 33 F.3d 1354, 1361 (Fed. Cir. 1994). Significantly, "Abstract software code is an idea without physical embodiment." Microsoft Corp. v. AT&T Corp., 550 U.S. 437, 449 (2007). The unpatentability of abstract ideas was confirmed by the U.S. Supreme Court in Bilski v. Kappos, No. 08-964, 2010 WL 2555192 (June 28, 2010).
