Classen v. Biogen: CAFC Tries To Target Patent Eligibility But Misses

Ryan Chirnomas, Partner in the Biotechnology group at Westerman, Hattori, Daniels and Adrian, sent in this article discussing the Court of Appeals for the Federal Circuit’s recent Classen v. Biogen decision.  He highlights the key points of the decision and why he believes this case is a missed opportunity to clarify the machine-or-transformation test of Bilski.

Not long after issuing opinions in AMP v. USPTO and Prometheus v. Mayo, the CAFC has again taken on the difficult questions of patent eligible subject matter in Classen v. Biogen.  In 2008, the CAFC issued a three-sentence non-precedential opinion holding that Classen’s claims do not recite patent eligible subject matter.  This decision was appealed to the Supreme Court and subsequently remanded to the CAFC after the Supreme Court’s Bilski decision.  The instant decision includes a discussion of patent-eligible subject matter, as well as the safe harbor exception to infringement of pharmaceutical patents.  This discussion is limited to questions of patent eligible subject matter.  This decision relates to three patents:  U.S. Patent Nos. 6,638,739 (“the ‘739 patent”), 6,420,139 (“the ‘139 patent”) and 5,723,283 (“the ‘283 patent”).

Federal Circuit Reverses Course On Classen

Our friends at Foley & Lardner sent in this article discussing the Federal Circuit’s decision in Classen Immunotherapies, Inc. v. Biogen Idec.

On August 31, 2011, the Federal Circuit issued its second decision in Classen Immunotherapies, Inc. v. Biogen Idec (App. 2006-1643, -1649), on remand from the Supreme Court after Bilski v. Kappos (U.S. 2010). The Federal Circuit first decided Classen’s appeal in 2008, when a panel comprised of Circuit Judges Newman and Moore and District Judge Farnan (sitting by designation) held in a one-paragraph, non-precedential decision authored by Judge Moore that Classen’s claims do not satisfy 35 USC § 101. The second time around, the Federal Circuit (by a panel that included Chief Judge Rader in place of Judge Farnan) took a closer look at Classen’s claims, and determined that two of the three Classen patents at issue indeed are directed to subject matter that is patent-eligible under 35 USC § 101. In this decision, the Federal Circuit has provided useful guidance for method claims that involve some type of information gathering. It appears that if the claims recite a step of “putting this knowledge to practical use,” such as an active treatment step based on the information, they are likely to be patent-eligible under 35 USC § 101. On the other hand, if the claimed methods culminate in obtaining information, and nothing more, they may be vulnerable to challenge under 35 USC § 101.

Judge Newman wrote the opinion for the court, which was joined by Chief Judge Rader. Chief Judge Rader wrote a separate opinion to express “additional views,” which was joined by Judge Newman. Judge Moore wrote a dissenting opinion. (more…)

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…)
