`United States Court of Appeals,
`Federal Circuit.
`In re Bernard L. BILSKI and Rand A. Warsaw.
`
`No. 2007–1130.
`Oct. 30, 2008.
`
`
`Background: Patent applicants challenged denial of
`patent application for method of hedging risk in field
`of commodities
`trading based on
`lack of pa-
`tent-eligible subject matter. The Patent and Trademark
`Office, Board of Patent Appeals and Interferences,
`2006 WL 5738364, sustained rejection of all claims in
`application. Applicants appealed.
`
`Holdings: Following sua sponte order of review en
`banc, the Court of Appeals, Michel, Chief Judge, held
`that:
`(1) machine-or-transformation test, rather than test
`determining whether claim recited algorithm applied
`in any manner to physical elements or process steps,
`was applicable test for determining patent-eligibility
`of process claims, abrogating, In re Freeman, 573
`F.2d 1237, In re Walter, 618 F.2d 758, and In re Abele,
`684 F.2d 902;
`(2) machine-or-transformation test, rather than “use-
`ful, concrete and tangible result” inquiry, was proper
`test to apply to determine patent-eligibility of process
`claims, abrogating In re Alappat, 33 F.3d 1526, State
`Street Bank & Trust Co. v. Signature Financial
`Group, Inc., 149 F.3d 1368, and AT&T Corp. v. Excel
`Communications, Inc., 172 F.3d 1352; and
`(3) claim was not drawn to patent-eligible subject
`matter under
`transformation branch of ma-
`chine-or-transformation test.
`
`
`Affirmed.

`The proper inquiry to determine patent-eligibility
`of process claims is not whether the process claim
`recites sufficient physical steps, but rather whether the
`claim meets the machine-or-transformation test; thus,
`it is simply inapposite to the analysis whether process
`steps performed by software on a computer are suffi-
`ciently physical. 35 U.S.C.A. § 101.

`Even a process claim that recites physical steps

`Bernard L. Bilski and Rand A. Warsaw (collec-
`tively, “Applicants”) appeal from the final decision of
`the Board of Patent Appeals and Interferences
`(“Board”) sustaining the rejection of all eleven claims
`of their U.S. Patent Application Serial No. 08/833,892
`'892 application”). See Ex parte Bilski,
`(“
`No.2002–2257, 2006 WL 5738364 (B.P.A.I. Sept. 26,
`2006) (“ Board Decision ”). Specifically, Applicants
`argue that the examiner erroneously rejected the
`claims as not directed to patent-eligible subject matter
`under 35 U.S.C. § 101, and that the Board erred in
`upholding that rejection. The appeal was originally
`argued before a panel of the court on October 1, 2007.
`Prior to disposition by the panel, however, we sua
`sponte ordered en banc review. Oral argument before
`the en banc court was held on May 8, 2008. We affirm
`the decision of the Board because we conclude that

`(Cite as: 545 F.3d 943)
`Applicants' claims are not directed to patent-eligible
`subject matter, and in doing so, we clarify the stand-
`ards applicable in determining whether a claimed
`method constitutes a statutory “process” under § 101.
`
`
`I.
`Applicants filed their patent application on April
`10, 1997. The application contains eleven claims,
`which Applicants argue together here. Claim 1 reads:
`
`
`A method for managing the consumption risk costs
`of a commodity sold by a commodity provider at a
`fixed price comprising the steps of:
`
`(a) initiating a series of transactions between said
`commodity provider and consumers of said
`commodity wherein said consumers purchase
`said commodity at a fixed rate based upon his-
`torical averages, said fixed rate corresponding to
`a risk position of said consumer;
`
`identifying market participants for said
`(b)
`commodity having a counter-risk position to said
`consumers; and
`
`(c) initiating a series of transactions between said
`commodity provider and said market participants
`at a second fixed rate such that said series of
`market participant transactions balances the risk
`position of said series of consumer transactions
`
`
`
`
`
`
`
`
`
`'892 application cl.1. In essence, the claim is for a
`method of hedging risk in the field of commodities
`trading. For example, coal power plants (i.e., the
`“consumers”) purchase coal to produce electricity and
`are averse to the risk of a spike in demand for coal
`since such a spike would increase the price and their
`costs. Conversely, coal mining companies (i.e., the
`“market participants”) are averse to the risk of a sud-
`den drop in demand for coal since such a drop would
`reduce their sales and depress prices. The claimed
`method envisions an *950 intermediary, the “com-
`
`Page 9
`
`modity provider,” that sells coal to the power plants at
`a fixed price, thus isolating the power plants from the
`possibility of a spike in demand increasing the price of
`coal above the fixed price. The same provider buys
`coal from mining companies at a second fixed price,
`thereby isolating the mining companies from the pos-
`sibility that a drop in demand would lower prices
`below that fixed price. And the provider has thus
`hedged its risk; if demand and prices skyrocket, it has
`sold coal at a disadvantageous price but has bought
`coal at an advantageous price, and vice versa if de-
`mand and prices fall. Importantly, however, the claim
`is not limited to transactions involving actual com-
`modities, and the application discloses that the recited
`transactions may simply involve options, i.e., rights to
`purchase or sell the commodity at a particular price
`within a particular timeframe. See J.A. at 86–87.
`
`
`The examiner ultimately rejected claims 1–11
`under 35 U.S.C. § 101, stating: “[r]egarding ... claims
`1–11, 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.” See
`Board Decision, slip op. at 3. The examiner noted that
`Applicants had admitted their claims are not limited to
`operation on a computer, and he concluded that they
`were not limited by any specific apparatus. See id. at 4.
`
`
`On appeal, the Board held that the examiner erred
`to the extent he relied on a “technological arts” test
`because the case law does not support such a test. Id. at
`41–42. Further, the Board held that the requirement of
`a specific apparatus was also erroneous because a
`claim that does not recite a specific apparatus may still
`be directed to patent-eligible subject matter “if there is
`a transformation of physical subject matter from one
`state to another.” Id. at 42. Elaborating further, the
`Board stated: “ ‘mixing’ two elements or compounds
`to produce a chemical substance or mixture is clearly a
`statutory transformation although no apparatus is
`claimed to perform the step and although the step

`could be performed manually.” Id. But the Board
`concluded that Applicants' claims do not involve any
`patent-eligible transformation, holding that transfor-
`mation of “non-physical financial risks and legal lia-
`bilities of the commodity provider, the consumer, and
`the market participants” is not patent-eligible subject
`matter. Id. at 43. The Board also held that Applicants'
`claims “preempt[ ] any and every possible way of
`performing the steps of the [claimed process], by
`human or by any kind of machine or by any combi-
`nation thereof,” and thus concluded that they only
`claim an abstract idea ineligible for patent protection.
`Id. at 46–47. Finally, 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. Id. at
`49–50.
`
`
`Applicants timely appealed to this court under 35
`U.S.C. § 141. We have jurisdiction under 28 U.S.C. §
`1295(a)(4)(A).

`
`II.
`[1][2][3][4] Whether a claim is drawn to pa-
`tent-eligible subject matter under § 101 is a threshold
`inquiry, and any claim of an application failing the
`requirements of § 101 must be rejected even if it meets
`all of the other legal requirements of patentability. In
`re Comiskey, 499 F.3d 1365, 1371 (Fed.Cir.2007) FN1
`(quoting *951Parker v. Flook, 437 U.S. 584, 593, 98
`S.Ct. 2522, 57 L.Ed.2d 451 (1978)); In re Bergy, 596
`F.2d 952, 960 (CCPA 1979), vacated as moot sub
`nom. Diamond v. Chakrabarty, 444 U.S. 1028, 100
`S.Ct. 696, 62 L.Ed.2d 664 (1980). Whether a claim is
`drawn to patent-eligible subject matter under § 101 is
`an issue of law that we review de novo. Comiskey, 499
`F.3d at 1373; AT & T Corp. v. Excel Commc'ns, Inc.,
`172 F.3d 1352, 1355 (Fed.Cir.1999). Although claim
`construction, which we also review de novo, is an
`important first step in a § 101 analysis, see State St.
`Bank & Trust Co. v. Signature Fin. Group, 149 F.3d
`1368, 1370 (Fed.Cir.1998) (noting that whether a
`claim is invalid under § 101 “is a matter of both claim
`
`Page 10
`
`construction and statutory construction”), there is no
`claim construction dispute in this appeal. We review
`issues of statutory interpretation such as this one de
`novo as well. Id.
`
`
`FN1. Although our decision in Comiskey
`may be misread by some as requiring in
`every case that the examiner conduct a § 101
`analysis before assessing any other issue of
`patentability, we did not so hold. As with any
`other patentability requirement, an examiner
`may reject a claim solely on the basis of §
`101. Or, if the examiner deems it appropriate,
`she may reject the claim on any other
`ground(s) without addressing § 101. But
`given that § 101 is a threshold requirement,
`claims that are clearly drawn to unpatentable
`subject matter should be identified and re-
`jected on that basis. Thus, an examiner
`should generally first satisfy herself that the
`application's claims are drawn
`to pa-
`tent-eligible subject matter.

`vention as claimed meets the requirements set forth in
`§ 101, we begin with the words of the statute:
