BILSKI: Where Do We Go From Here?

The following guest post comes from  Kenneth Nigon, Practice Manager for the Patent Preparation and Prosecution Group at RatnerPrestia and PLI Faculty member.

On Tuesday, July 27, the USPTO published its Interim Guidance for Determining Subject Matter Eligibility for Process Claims in view of Bilski v. Kappos (“Interim Bilski Guidance”).  This Guidance supplements the Interim Examination Instructions for Evaluating Subject Matter Eligibility Under 35 U.S.C. § 101 (“Interim Instructions”), published on August 24, 2009 and the memorandum to the Patent Examining Corps on the Supreme Court Decision in Bilski v Kappos published on June 28, 2010 (“Bilski Memorandum”).

The Bilski Memorandum instructs the examiners to reject method claims that do not meet the requirements of the Machine or Transformation (MoT) test formulated by the Federal Circuit in In re Bilski 545 F.3d 943 (Fed. Cir. 2008).  The Interim Bilski Guidance modifies these instructions to require examiners to apply a balancing test which weighs factors both in favor of and opposed to patent eligibility and directs examiners to consider all requirements for patentability in the interest of compact prosecution.
