The “process” of patenting: Why should we care about a potential U.S. Supreme Court decision in Bilski v. Doll?

In Bilski v. Doll, the U.S. Supreme Court is called to define one of the categories of patent-eligible subject matter, “process” patents. In 2008, the Court of Appeals for the Federal Circuit held that the category has a narrow meaning, and that to be eligible for a process patent under 35 U.S.C. § 101, the invention must involve a machine or apparatus or involve a transformation to a different state or thing, ultimately rejecting the patent application as unpatentable subject matter. The patent applicants have asked the U.S. Supreme Court to determine two issues: first, the meaning of “process” in 35 U.S.C. § 101 and whether the lower court properly relied on a “machine-or-transformation” test, and second, the test's potential conflict with 35 U.S.C. § 273, which provides protection for “method[s] of doing or conducting business.” The Court's decision could change the way that research and business are done, and patent protection for such investments. Parts 1 and 2 of this article address Bilski directly and what is and is not in dispute. Part 3 addresses the “machine-or-transformation” test, while Parts 4 and 5 address reasons not to adopt such a test.
