Bilski v. Kappos, 08–964

In a patent application seeking protection for a claimed invention explaining how commodities buyers and sellers in the energy market could protect, or hedge, against the risk of price changes, the denial of the application is affirmed where: 1) the machine-or-transformation test is not the sole test for patent eligibility under 35 U.S.C. section 101; 2) Section 101 precluded a reading of the term "process" that would categorically exclude business methods; and 3) even though petitioners' application was not categorically outside of section 101 under the two atextual approaches the Court rejected today, that did not mean it was a "process" under section 101.
