Interim Guidance for Determining Subject Matter Eligibility for Process Claims in View of Bilski v. Kappos

The USPTO has prepared Interim Guidance for Determining Subject Matter Eligibility for Process Claims in view of Bilski v. Kappos (Interim Bilski Guidance) for its personnel to use when determining subject matter eligibility under 35 U.S.C. 101 in view of the recent decision by the United States Supreme Court (Supreme Court) in Bilski v. Kappos, No. 08-964 (June 28, 2010).  It is intended to be used by Office personnel as a supplement to the previously issued Interim Examination Instructions for Evaluating Subject Matter Eligibility Under 35 U.S.C. 101 dated August 24, 2009 (August 2009 Interim Instructions) and the memorandum to the Patent Examining Corps on the Supreme Court Decision in Bilski v. Kappos dated June 28, 2010.  The August 2009 Interim Instructions are to be consulted for determining subject matter eligibility under 35 U.S.C. § 101 of machine, composition, and manufacture claims.

101 Method Eligibility Quick Reference Sheet

The Interim Bilski Guidance provides factors to consider in determining whether a claim is directed to an abstract idea and is therefore not patent-eligible under 35 U.S.C. § 101.  Under the Interim Bilski Guidance, factors that weigh in favor of patent-eligibility satisfy the criteria of the machine-or-transformation test or provide evidence that the abstract idea has been practically applied, and factors that weigh against patent-eligibility neither satisfy the criteria of the machine-or-transformation test nor provide evidence that the abstract idea has been practically applied. 

A summary sheet of these factors is available here.
