Bilski v. Kappos (2010, USA)
Bilski v. Kappos (originally named Bilski v. Doll) is the name of the case in the USA where the Supreme Court reviewed the CAFC's 2008 in re Bilski ruling. The hearing was held in November 2009 and the decision was delivered in June 2010. Bilski was important because it was the first time since 1981 (Diamond v. Diehr) that the Supreme Court gave a ruling about whether or not a certain patent was valid patentable subject matter.
The patent being defended by Bilski is on a business method, but the test created in the in re Bilski ruling - the "particular machine or transformation" test - is broad enough to block the patenting of some software ideas too. The in re Bilski ruling has already been used by the USPTO to reject certain software patent applications, and a District Court has used it to invalidate a patent.

 Questions posed to the Supreme Court
The Supreme Court has accepted to review this ruling for the purpose of answering two questions:
- 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 ("machine-or- transformation" test), to be eligible for patenting under 35 U.S.C. §101, 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.", and
- 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.
