- In Re Bilski (Fed. Cir.; October 30, 2008)
In In Re Bilski, the Court of Appeals for the Federal Circuit in Washington, DC, sitting en banc, considered the issue of whether certain so-called business methods and other “processes” are eligible for patent protection. Less than a day after the court’s eagerly-anticipated decision, general and legal news media outlets proclaimed the end of patent protection for software-related business methods, and shortly thereafter business associations called for patent reform legislation to expand the Patent Act’s scope to reestablish protections for software inventions. It may take days and perhaps weeks for the debate to subside over exactly how far the Bilski court swung the pendulum away from the pro-patent apex. What is clear, however, is that Bilski did not do away with business methods and general software process patents entirely, although it did tighten the patent eligibility standard for inventions involving processes.
Section 101 of the Patent Act identifies four categories of patent-eligible subject matter: processes, machines, manufactures, and compositions of matter. The patent claims at issue in Bilski involved a computerized process, specifically a method of hedging risk in the field of commodities trading.
Drawing extensively from the Supreme Court’s holding and analysis in Diamond v. Diehr, 450 U.S. 175 (1981) and Gottschalk v. Benson, 409 U.S. 63, 67 (1972), the Federal Circuit recognized that “the question before us then is whether Applicants' claim recites a fundamental principle [i.e., "laws of nature, natural phenomena, and abstract ideas"] and, if so, whether it would pre-empt substantially all uses of that fundamental principle if allowed.” The definitive test, the court said, involves a determination of whether a process claim is tailored narrowly enough to encompass only a particular application of a fundamental principle rather than to pre-empt the principle itself.
A claimed process, the court said, is patent-eligible under § 101 if: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing.
