What in Blazes Is “In re Bilski”?

• Bernard Bilski & Rand Warsaw filed a US patent application April 10, 1997, 08/833,892, for hedging of risks in energy commodities trading.

• PTO examiner rejected all 11 initial Bilski claims because "the invention is not implemented on a specific apparatus and merely manipulates [an] abstract idea and solves a purely mathematical problem without any limitation to a practical application, therefore, the invention is not directed to the technological arts."

Bilski Appeals

• Bilski appealed examiner's rejection to Board of Patent Appeals & Interferences BPAI. BPAI sustained the rejection of Bilski's claims, but on different grounds. "The Board concluded that Applicants' claims did not involve any patent-eligible transformation, holding that transformation of "non-physical financial risks and legal liabilities of the commodity provider, the consumer, and the market participants" is not patent-eligible subject matter."

Bilski Appeals to BPAI

• BPAI the Board held that Applicants' process as claimed did not produce a "useful, concrete and tangible result," and for this reason as well was not drawn to patent-eligible subject matter. That is, BPAI sustained a 35USC101 rejection of Bilski, claims drawn to non-patent eligible subject matter.

Bilski Appeals to CAFC

• Bilski, not one to quit easily, appealed the BPAI ruling to the CAFC. The initial CAFC Panel, sua sponte, invoked an en banc hearing of the entire CAFC to consider the Bilski appeal. Their ruling,

• 545 F.3d 943, 88 U.S.P.Q.2d 1385 (Fed. Cir. 2008), sustained the BPAI rejection of Bilski's claims, but also overturned a prior important business methods patents decision of the CAFC, State Street Bank & Trust Co. v. Signature Financial Group, Inc., 149 F.3d 1368 (Fed. Cir. 1998). In State Street, the CAFC had ruled that business methods claim is eligible for protection by a patent in the United States if it involved some practical application and it produces a useful, concrete and tangible result.

CAFC Rules In re Bilski

• Useful, concrete & tangible results no longer the test of 101 for method claims!

• Must be tied to a machine or produce a transformation – machine or transformation sole test of method claims 101 eligibility!

• Process claims likely swept into question!

Bilski Appeals to Supreme Court

• Bilski has appealed to US Supreme Court. Amicus briefs in support of USSC granting certiorari include Medistem's, where they argue:

• The Federal Circuit’s limiting the scope of patentable subject matter for “process” inventions in Bilski casts a cloud of uncertainty as to whether Medistem and other biotech companies can continue to protect with patents their inventions relating to methods of diagnosing causes of diseases and methods of selecting beneficial treatment protocols. "

Amicus Brief Process Worries

• That is not simply Medistem's fear, but a not unlikely uncome of the Bilski decision according to Judge Rader's dissent against CAFC Bilski decision:

• Judge Rader cogently noted that excluding patent protection for methods of using discovered biological or physiologi-cal correlations will “undermine and discourage future research for diagnostic tools.” Bilski, 545 F.3d at 1014. Medistem p3

Medistem’s Concerns

• Although the patent at issue in Bilski claimed a business method, the Federal Circuit did not confine its adoption of the “machine-or-transformation” test to business methods. Instead, the court more broadly considered “what test or set of criteria governs the determination by the Patent and Trademark Office (‘PTO’) or courts as to whether a claim to a process is patentable under § 101 or, conversely, is drawn to unpatentable subject matter because it claims only a fundamental principle.” 545 F.3d at 952 (emphasis added). It answered that question by holding that “the machine-or-transformation test is the only applicable test and must be applied . . . when evaluating the patent-eligibility of process claims.” Medistem p5

If Bilski Reads on All Process Claims!?

• If the machine or transformation test is the sole test of 101 eligibility of process or method claims, pharma, medtech, & diagnostics all at likely risk!
