Bilski v. Doll: Round I of Amicus Briefs

Bilski v. Doll (on petition for writ of certiorari 2009)

In a 2008 en banc decision, the Federal Circuit affirmed a Patent Office ruling that Bernard Bilski’s claimed method of hedging the risk of bad weather through commodities trading was not patent eligible under Section 101 of the patent act. The Court applied a “machine-or-transformation test” as the only test to be used in determining whether a claimed process is eligible for patenting under § 101. The decision holds that a claimed process either (1) be tied to a particular machine or apparatus or (2) transform a particular article into a different state or thing. Although the Court identified the Bilski test as the only test, it added two corollaries: (1) the addition of a mere field-of-use limitation without other meaningful limits on claim scope will not render a method claim patent eligible; and (2) insignificant extra-solution limitations will not render a method claim patent eligible.

Bilski has petitioned the Supreme Court to hear its appeal and look at the question of patentable subject matter for the first time in a generation. Diamond v. Chakrabarty and Diamond v. Diehr together opened the door for broader patent eligible subject matter. Notably, Justice Stevens – author of the Diehr dissent – is the only justice still on the bench. Bilski’s petition asks two questions:

1.       Whether the Federal Circuit erred by holding that a “process” must be tied to a particular machine or apparatus, or transform a particular article into a different state or thing … despite this Court’s precedent declining to limit the broad statutory grant of patent eligibility for “any” new and useful process beyond excluding patents for “laws of nature, physical phenomena, and abstract ideas.”

2.       Whether the Federal Circuit’s “machine-or-transformation” test for patent eligibility, which effectively forecloses meaningful patent protection to many business methods, contradicts the clear Congressional intent that patents protect “method[s] of doing or conducting business.” 35 U.S.C. § 273.

The first round of Amicus briefs – those supporting the petition – have now been filed. The PTO’s briefs and briefs in opposition to the petition are due in early April.
