Machine-Or-Transformation Test After Myriad: Implications To The Prosecution Of Process Claims

Michael Davitz, Partner at Axinn, Veltrop & Harkrider and Practice Center Contributor, recently sent in this article he wrote with colleague’s Josephine Liu and Stacie Ropka discussing recent case law on the patentability of process claims.

Not all inventions are patentable.  The Federal Circuit recently handed down its decision in Myriad[i] and the Supreme Court will be hearing Prometheus[ii] in the term beginning in October 2011.  The issues in both Myriad and Prometheus highlight the difficulty in determining when a claim directed to a process is patentable subject matter under § 101, a determination that is particularly troubling in many inventions related to the life sciences.

A first step for granting a patent is determining whether or not a patent application claims patentable subject-matter.  In a line of cases from the late 70s to early 80s and reaffirmed in 2010, the Supreme Court explained that 35 U.S.C. § 101 is to be interpreted broadly and has articulated only three exceptions to what is patentable:  (1) laws of nature; (2) physical phenomena; and (3) abstract ideas.[iii] With respect to process claims, the line between patentable “processes” and unpatentable principles or abstract ideas is not always clear.  The Supreme Court has yet to provide a concrete test by which such a distinction can be made.[iv] It did, however, provide a hint in Gottschalk v. Benson stating that “[t]ransformation and reduction of an article ‘to a different state or thing’ is the clue to the patentability of a process claim that does not include particular machines.”[v] From this pronouncement, the Federal Circuit formally presented and applied the machine-or-transformation test in In re Bilski.[vi] (more…)
