Claims rejected, Ex parte Bilski (BPAI 2006), appealed to CAFC, en banc hearing ordered sua sponte.
Subsequent history
Bilski v. Kappos, 561 U.S. ___(2010) (Aff'd, Machine or Transformation test not the sole test for patent-eligible subject matter)
Holding
The "useful, concrete and tangible result" test of State Street should no longer be relied on. A method claim is surely patentable subject matter if (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing. BPAI affirmed.
In In re Ferguson, 558 F.3d 1359, 1364–65 (Fed. Cir. 2009), the Federal Circuit spoke of the Bilski case as setting forth "this court's clear statements that the 'sole,' 'definitive,' 'applicable,' 'governing,' and 'proper' test for a process claim under § 101 is the Supreme Court's machine-or-transformation test."
The decision of the Federal Circuit in In re Bilski was appealed to the Supreme Court of the United States as Bilski v. Kappos.[1][2][3] Although the SCOTUS affirmed the judgment of the CAFC, it revised many aspects of the CAFC's methodology. More specifically the majority in its decision rejected the machine-or-transformation test as the sole test of process patent eligibility based on an interpretation of the language of § 101.[4] The majority, however, had high praise for the Federal Circuit opinions, advising that "[s]tudents of patent law would be well advised to study these scholarly opinions."[5]
The serial number for the patent application is 08/833,892. The text is available on the USPTO web site.[6] The patent application describes a method for providing a fixed bill energy contract to consumers. Under fixed bill energy contracts, consumers pay monthly prices for their future energy consumption in advance of winter based on their past energy use. The monthly prices remain the same no matter how much energy they then use. Thus, consumers save money relative to others if, for example, a given winter is unusually cold and they use an unusually large amount of energy for heating. On the other hand, consumers pay more than others if a winter is unusually warm and their energy use is lower than average.
Method claim 1 of the patent application claims a three-step method for a broker to hedge risks for purchaser-users of an input of a product or service (termed a commodity). For example, an electric power plant might be a purchaser and user of coal, which it purchases from coal-mining companies (producer-sellers) and uses to make electricity. The power plant might seek to insulate itself from upward changes in the price of coal by engaging in "hedging" transactions. The risk can be quantified in terms of dollars (termed a "risk position"). Thus, if the purchaser-user uses 1000 tons of coal in a given period, and the potential price spike is $10 per ton, the purchaser-user's total risk position for that period is 1000 × $10, or $10,000.
The claimed process comprises these steps (simplified for easier readability):
initiating a series of sales or options transactions between a broker and purchaser-users by which the purchaser-users buy the commodity at a first fixed rate based on historical price levels;
identifying producer-sellers of the commodity; and
initiating a series of sales or options transactions between the broker and producer-sellers, at a second fixed rate, such that the purchasers' and sellers' respective risk positions balance out.
The patent examiner rejected all 11 of the claims on the grounds that "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."[7]
The applicants appealed the rejection to the Board of Patent Appeals and Interferences (BPAI), which affirmed the rejection, although on different grounds. 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. 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." 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. 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 combination thereof," and thus concluded that they only claim an abstract idea ineligible for patent protection. 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.[7]
The applicants appealed the rejection to the Federal Circuit. The case was argued before a panel of the court on October 1, 2007. The court then ordered an en banc rehearing sua sponte, which was held on May 8, 2008. The Federal Circuit issued its decision on October 30, 2008.[8]
Majority opinion
The en banc Federal Circuit upheld the rejection, 9–3. The majority opinion by Chief Judge Paul Redmond Michel characterized the issue as whether the claimed method is a patent-eligible "process," as the patent statute (35 U.S.C. § 101) uses that term. While any series of actions or operations is a process in the dictionary sense of that term, the court explained, the Supreme Court has held that the statutory meaning is narrower than the dictionary meaning which "forecloses a purely literal reading." Patent-eligible processes do not include "laws of nature, natural phenomena, [or] abstract ideas." The limiting legal principle applies not just to processes, but to anything on which a patent is sought. As a trilogy of Supreme Court decisions on patent-eligibility from approximately three decades ago had taught, "Phenomena of nature, though just discovered, mental processes, and abstract intellectual concepts are not patentable, as they are the basic tools of scientific and technological work."[9] Therefore, the question was whether Bilski's process fell within any of the prohibited categories (that is, was a claim to a "principle"), and the underlying legal question was what legal tests or criteria should govern that determination when a claim is directed to a principle.
The court concluded that prior decisions of the Supreme Court were of limited usefulness as guides because they represented polar cases on the abstraction and concreteness spectrum. Nonetheless, a legal test could be distilled from them: "A claimed process is surely patent-eligible under § 101 if: (1) it is tied to a particular machine or apparatus, or (2) it transforms a particular article into a different state or thing." Not only did the patent-eligibility trilogy (Benson, Flook, and Diehr) support this test, the court explained, but so too did earlier Supreme Court precedents dating back well into the 19th century.
The court then considered whether this two-branch test should be considered all-inclusive, that is, as stating indispensable conditions of patent-eligibility. It concluded that the answer was affirmative, even though much of the language in the Supreme Court's patent-eligibility trilogy was more reserved.[10]
The Federal Circuit placed great weight on the use of the definite article in several Supreme Court statements that transformation and use of a particular machine provided "the clue to the patentability of a process claim." At the same time the court placed no weight on the fact that the Benson Court had not accepted the Government's argument that the case law "cannot be rationalized otherwise."[11]
The Federal Circuit observed that two caveats exist to the transformation-machine test: (1) a field-of-use limitation is insufficient to avoid the prohibition against pre-emption, as Flook expressly held; and (2) conventional or obvious "insignificant post-solution activity" does not make what is otherwise a claim to a principle patent-eligible (again referring to Flook). The court added that insignificant pre-solution activity (such as data-gathering) is equally ineffective, and so too is an insignificant step in the middle of a process (such as recording a result).
The court then rejected other proposed tests of patent-eligibility that had been suggested since the Supreme Court's trilogy. Several Federal Circuit panel decisions had held that a process was patent-eligible if it produced "a useful, concrete, and tangible result" — such as the transformation of financial data from one form to another form. Thus, in the State Street Bank v. Signature Financial Group case [12] the court had upheld a patent on a tax-avoidance scheme under this standard. The court now recognized that this test is "inadequate," as a dissenting Supreme Court opinion had already stated,[13] and therefore backed away from the language, denying that the Federal Circuit had ever "intended to supplant the Supreme Court's test." The court did not, however, expressly hold that State Street should be overruled: it merely dropped a footnote stating that "those portions of our opinions in State Street and AT&T relying solely on a 'useful, concrete and tangible result' analysis should no longer be relied on."
The court next turned to the "technological arts" test (a patent-eligible advance must be "technological" in nature) and rejected it on several grounds: The meanings of "technological arts" and "technology" are disputed and ambiguous. No court has ever adopted the test. The technological-arts test is not an equivalent of or "shortcut," the court insisted, that can be used instead of the transformation-machine test. "Rather, the machine-or-transformation test is the only applicable test and must be applied, in light of the guidance provided by the Supreme Court and this court, when evaluating the patent-eligibility of process claims."
On the other hand, the court refused to adopt a test that barred business methods, under that rubric, from patent-eligibility. Also, while the court stated that the machine-or-transformation test was the applicable test, the Supreme Court in Benson had stated that there could be cases where a claim that fails the "requirements of [its] prior precedents" may still nonetheless be patent-eligible subject matter. Benson, 409 U.S. at 71. Similarly, software could not categorically be excluded. The court also stated that future developments may alter the standing or the application of the test.
Bilski's method
Turning finally to Bilski's method, the court held it patent-ineligible. First, the court said, Bilski did not argue that the rejected claims recited any specific or "particular" machine, so that the court found it unnecessary to decide any issues relating to the machine-implementation branch of the test. "We leave to future cases the elaboration of the precise contours of machine implementation, as well as the answers to particular questions, such as whether or when recitation of a computer suffices to tie a process claim to a particular machine."[14] Second, the court turned to transformation of articles from one thing or state to another. What is an "article"? Benson had made it clear that tanning hides, smelting ores, and vulcanizing rubber were all instances of transforming articles. This corresponded to the transformation test as the PTO and some amici curiae articulated it: one physical substance is transformed into a second physical substance. But what of electronic signals and electronically manipulated data? Or even more abstract constructs such as legal obligations, which the Bilski case involved? No Supreme Court precedents addressed such entities.
Some Federal Circuit decisions, however, had held some transformations of signals and data patent-eligible. For example, the Abele decision approved a dependent claim to a method transforming X-ray attenuation data produced in a X-Y field by an X-ray tomographic scanner to an image of body organs and bones — while at the same time the Abele court rejected a more generic and abstract independent claim to a process of graphically displaying variances from their average values of unspecified data obtained in an unspecified manner.[15] The court said that this kind of difference between the two claims was critical to patent-eligibility. The dependent claim, unlike the independent claim, involved signal data representing tangible physical objects, which were electronically manipulated to provide a screen image of the physical objects. But Bilski's process had nothing to do with such a procedure. Like State Street, Bilski involved manipulation of financial data.
Bilski's method claim was patent-ineligible because it did not "transform any article to a different state or thing." Legal obligations (such as options and futures contracts) and business risks "cannot meet the test because they are not physical objects or substances, and they are not representative of physical objects or substances." Moreover, to the extent that signals are involved and are transformed, they are not "representative of any physical object or substance." Accordingly, Bilski's claim entirely failed the transformation-machine test.
Concurrences and dissents
Concurrence by Judge Dyk
Judge Dyk, joined by Judge Linn, concurred in the majority opinion upholding the PTO's rejection of Bilski's patent, but concurred also in Judge Mayer's historical analysis that the framers of the Constitution intended to exclude from the operation of the US patent system "methods for organizing human activity that do not involve manufactures, machines, or compositions of matter." Since Bilski's method failed that test, it is patent-ineligible.
Dissent by Judge Mayer
Judge Mayer dissented, first, on the ground that the majority opinion failed to overrule State Street explicitly. Whether this should be done was a question that the court had asked to be briefed on the re-argument. "I would answer that question with an emphatic 'yes.'" He then moved to the major thrust of his dissent: business-method patents are unconstitutional, or the patent statute must be interpreted not to extend to them in order to avoid unconstitutionality. He maintained:
The patent system is intended to protect and promote advances in science and technology, not ideas about how to structure commercial transactions. Claim 1 of the application . . . is not eligible for patent protection because it is directed to a method of conducting business. Affording patent protection to business methods lacks constitutional and statutory support, serves to hinder rather than promote innovation and usurps that which rightfully belongs in the public domain. State Street and AT&T should be overruled.[citation needed]
Pointing to the Statute of Monopolies and the public hostility to the "odious monopolies," he concluded that when Congress enacted the first patent statute (in language substantially unchanged to this day in regard to patent-eligibility), Congress did not want the system to allow patents on methods of conducting trade.[16]State Street was a grave error. "Before State Street led us down the wrong path, this court had rightly concluded that patents were designed to protect technological innovations, not ideas about the best way to run a business."
Judge Mayer also criticized the majority opinion for doing nothing to remedy the ills of a "patent system [that] has run amok," for evading crucial issues, and for failing to enlighten users of the patent system in regard to
three of the thorniest issues in the patentability thicket: (1) the continued viability of business method patents, (2) what constitutes sufficient physical transformation or machine-implementation to render a process patentable, and (3) the extent to which computer software and computer-implemented processes constitute statutory subject matter.[citation needed]
Dissent by Judge Rader
Judge Rader dissented on the ground that the majority should have "said in a single sentence: 'Because Bilski claims merely an abstract idea, this court affirms the Board's rejection.'" He then complained that instead of doing that, the majority opinion
propagates unanswerable questions: What form or amount of "transformation" suffices? When is a "representative" of a physical object sufficiently linked to that object to satisfy the transformation test? (E.g., Does only vital sign data taken directly from a patient qualify, or can population data derived in part from statistics and extrapolation be used?) What link to a machine is sufficient to invoke the "or machine" prong? Are the "specific" machines of Benson required, or can a general purpose computer qualify? What constitutes "extra-solution activity?" If a process may meet eligibility muster as a "machine," why does the Act "require" a machine link for a "process" to show eligibility?[citation needed]
Judge Rader indicated his belief that nothing is wrong with patents on business methods or natural phenomena, so long as they are claimed to "achieve a useful, tangible, and concrete result." In his view, the LabCorp dissent's criticism of that test, and of business method patents generally, misses the point of the needs of 21st century innovation and entrepreneurship.
Dissent by Judge Newman
Judge Newman dissented on the ground that the PTO should have allowed Bilski's patent. The opinion largely constitutes a debate with Judge Dyk's concurrence about whether the Statute of Monopolies, common law precedents, and the widespread opposition to the "odious monopolies" led to a ban on business-method patents in the US. Judge Newman insists that "[i]t is inconceivable that on this background the Framers, and again the enactors of the first United States patent statutes in 1790 and 1793, intended sub silentio to impose the limitations on 'process' now created by this court."
In short, Judge Newman felt that the current definition of the word process used by the court directly contradicted the statute, the precedent, and the constitutional mandate to promote the useful arts and science. Because the court's decision could affect thousands of patents already granted, Newman warned of uncertainty in patent eligible matter which serves as a disincentive to innovation.
Impact
Prior to the Supreme Court's decision on appeal, it was widely reported that the Bilski decision would call into question the validity of many already issued business method patents.[17] This issue has received global news coverage with a generally favorable assessment of the judgment.[18] According to the Associated Press, the decision "could reshape the way banks and high-tech firms protect their intellectual property."[19] Moreover, as a result of the decision, according to The Washington Post and others, many business method patents, possibly thousands, may now be invalid.[17][20]
Subsequent decisions by the BPAI used Bilski to reject claims related to more traditional computer implemented inventions. Four out of five of the initial rejections based on Bilski, for example, involved IBM patent applications not in the business method area.[21]
In January 2009, Bilski and Warsaw petitioned the U.S. Supreme Court for a writ of certiorari, seeking to overturn the Federal Circuit decision.[22] It was granted on June 1, 2009. (This eventually led to the Supreme Court's decision in Bilski v. Kappos.)
In March 2009, a Federal Circuit panel split over what Bilski had held. In In re Ferguson the majority opinion (per Judge Gajarsa, joined by Judge Mayer) stated that Bilski has held that the "useful, concrete and tangible result test" "is insufficient to determine whether a claim is patent-eligible under § 101," that it "is inadequate," and that "those portions of our opinions in State Street and AT&T Corp. v. Excel Communications, Inc. relying on a 'useful, concrete and tangible result' analysis should not longer be relied on."[23] In addition, the Ferguson majority said, "In Bilski, this court also rejected the so-called Freeman-Walter-Abele Test, the "technological arts" test, and the "physical steps" test."[24] In her dissenting opinion, Judge Newman took issue with the majority opinion as an erroneous "sweeping rejection of precedent." She insisted that Bilski had left State Street partly in effect. She argued that Bilski had "recognized that the State Street Bank test was directed to processes performed by computer, "thus meeting the Bilski test" and pointed to note 18 of the Bilski opinion, which stated, "In State Street, as is often forgotten, we addressed a claim drawn not to a process but to a machine."[25][26]
A March 2009 district court opinion interpreting Bilski "ponder[ed] whether the end has arrived for business method patents."[27] The court then observed:
Without expressly overruling State Street, the Bilski majority struck down its underpinnings. This caused one dissenter, Judge Newman, to write that State Street "is left hanging," while another dissenter, Judge Mayer, registered "an emphatic 'yes'" to rejecting State Street.... Although the majority declined to say so explicitly, Bilski's holding suggests a perilous future for most business method patents.[27]
The court concluded, "The closing bell may be ringing for business method patents, and their patentees may find they have become bagholders."[27]
While the Supreme Court's opinion in Bilski v. Kappos, affirming the judgment but limiting the scope of the machine-or-transformation test, largely superseded the Federal Circuit's Bilski opinion as a precedent, nonetheless, much of the substantive content of the Federal Circuit majority opinion is repeated and found in the Supreme Court's Bilski opinion and subsequently in Alice as well. The statistics on invalidations under §101, show that, as of June 2015, "the 73.1% invalidity rate in the federal courts breaks down into 70.2% (66 of 96) in the district courts and a stunning 92.9% in the Federal Circuit (13 for 14)." At the same time, final rejections of business-method patent claims before the PTO "soared into the 90% range."[28]

Neither software nor computer programs are explicitly mentioned in statutory United States patent law. Patent law has changed to address new technologies, and decisions of the United States Supreme Court and United States Court of Appeals for the Federal Circuit (CAFC) beginning in the latter part of the 20th century have sought to clarify the boundary between patent-eligible and patent-ineligible subject matter for a number of new technologies including computers and software. The first computer software case in the Supreme Court was Gottschalk v. Benson in 1972. Since then, the Supreme Court has decided about a half dozen cases touching on the patent eligibility of software-related inventions.
State Street Bank and Trust Company v. Signature Financial Group, Inc., 149 F.3d 1368, also referred to as State Street or State Street Bank, was a 1998 decision of the United States Court of Appeals for the Federal Circuit concerning the patentability of business methods. State Street for a time established the principle that a claimed invention was eligible for protection by a patent in the United States if it involved some practical application and, in the words of the State Street opinion, "it produces a useful, concrete and tangible result."
Business method patents are a class of patents which disclose and claim new methods of doing business. This includes new types of e-commerce, insurance, banking and tax compliance etc. Business method patents are a relatively new species of patent and there have been several reviews investigating the appropriateness of patenting business methods. Nonetheless, they have become important assets for both independent inventors and major corporations.
Diamond v. Diehr, 450 U.S. 175 (1981), was a United States Supreme Court decision which held that controlling the execution of a physical process, by running a computer program did not preclude patentability of the invention as a whole. The high court reiterated its earlier holdings that mathematical formulas in the abstract could not be patented, but it held that the mere presence of a software element did not make an otherwise patent-eligible machine or process patent ineligible. Diehr was the third member of a trilogy of Supreme Court decisions on the patent-eligibility of computer software related inventions.
Ex Parte Bowman 61 U.S.P.Q.2d 1669 was a decision by the U.S. Board of Patent Appeals and Interferences which asserted that in order to be patent-eligible, a process had to involve or promote the technological arts. This decision was overruled by the Board's subsequent Ex Parte Lundgren decision, but the Board's and then the Federal Circuit's In re Bilski opinion then superseded Lundgren. In re Bilski, however, rejects use of "not in the technological arts" as a basis for a rejection, although it seems to accept the concept when differently named. Bilski was affirmed by the Supreme Court in Bilski v. Kappos.
Gottschalk v. Benson, 409 U.S. 63 (1972), was a United States Supreme Court case in which the Court ruled that a process claim directed to a numerical algorithm, as such, was not patentable because "the patent would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself." That would be tantamount to allowing a patent on an abstract idea, contrary to precedent dating back to the middle of the 19th century. The ruling stated "Direct attempts to patent programs have been rejected [and] indirect attempts to obtain patents and avoid the rejection ... have confused the issue further and should not be permitted." The case was argued on October 16, 1972, and was decided November 20, 1972.
Freeman-Walter-Abele is a now outdated judicial test in United States patent law. It came from three decisions of the United States Court of Customs and Patent Appeals—In re Freeman, 573 F.2d 1237, In re Walter, 618 F.2d 758 ; and In re Abele, 684 F.2d 902 —which attempted to comply with then-recent decisions of the Supreme Court concerning software-related patent claims.
Dann v. Johnston, 425 U.S. 219 (1976), is a decision of the United States Supreme Court on the patentability of a claim for a business method patent.
In United States patent law, the machine-or-transformation test is a test of patent eligibility under which a claim to a process qualifies for consideration if (1) the process is implemented by a particular machine in a non-conventional and non-trivial manner or (2) the process transforms an article from one state to another.
In re Ferguson, 558 F.3d 1359 is an early 2009 decision of the United States Court of Appeals for the Federal Circuit, affirming a rejection of business method claims by the United States Patent and Trademark Office (USPTO). One of the first post-Bilski decisions by a Federal Circuit panel, Ferguson confirms the breadth of the en banc Bilski opinion's rejection of the core holdings in State Street Bank & Trust Co. v. Signature Financial Group, Inc.
Bilski v. Kappos, 561 U.S. 593 (2010), was a case decided by the Supreme Court of the United States holding that the machine-or-transformation test is not the sole test for determining the patent eligibility of a process, but rather "a useful and important clue, an investigative tool, for determining whether some claimed inventions are processes under § 101." In so doing, the Supreme Court affirmed the rejection of an application for a patent on a method of hedging losses in one segment of the energy industry by making investments in other segments of that industry, on the basis that the abstract investment strategy set forth in the application was not patentable subject matter.
AT&T Corp. v. Excel Communications, Inc., 172 F.3d 1352 was a case in which the United States Court of Appeals for the Federal Circuit reversed the decision of the United States District Court for the District of Delaware, which had granted summary judgment to Excel Communications, Inc. and decided that AT&T Corp. had failed to claim statutory subject matter with U.S. Patent No. 5,333,184 under 35 U.S.C. § 101. The United States Court of Appeals for the Federal Circuit remanded the case for further proceedings.
Mayo v. Prometheus, 566 U.S. 66 (2012), was a case decided by the Supreme Court of the United States that unanimously held that claims directed to a method of giving a drug to a patient, measuring metabolites of that drug, and with a known threshold for efficacy in mind, deciding whether to increase or decrease the dosage of the drug, were not patent-eligible subject matter.
CyberSource Corp. v. Retail Decisions, Inc., 654 F.3d 1366, is a United States Court of Appeals for the Federal Circuit case that disputed patent eligibility for the '154 patent, which describes a method and system for detecting fraud of credit card transactions through the internet. This court affirmed the decision of United States District Court for the Northern District of California which ruled that the patent is actually unpatentable.
Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), was a 2014 United States Supreme Court decision about patent eligibility of business method patents. The issue in the case was whether certain patent claims for a computer-implemented, electronic escrow service covered abstract ideas, which would make the claims ineligible for patent protection. The patents were held to be invalid, because the claims were drawn to an abstract idea, and implementing those claims on a computer was not enough to transform that abstract idea into patentable subject matter.
In re Lowry, 32 F.3d 1579 was a 1994 decision of the United States Court of Appeals for the Federal Circuit on the patent eligibility of data structures. The decision, which reversed a PTO rejection of data structure claims, was followed by a significant change in PTO policy as to granting software related patents, a cessation of PTO appeals to the Supreme Court from reversals of PTO rejections of software patent applications, an increasing lenity at the Federal Circuit toward such patents and patent applications, and a great increase in the number of software patents issued by the PTO.
In re Alappat, 33 F.3d 1526, along with In re Lowry and the State Street Bank case, form an important mid-to-late-1990s trilogy of Federal Circuit opinions because in these cases, that court changed course by abandoning the Freeman-Walter-Abele Test that it had previously used to determine patent eligibility of software patents and patent applications. The result was to open a floodgate of software and business-method patent applications, many or most of which later became invalid patents as a result of Supreme Court opinions in the early part of the following century in Bilski v. Kappos and Alice v. CLS Bank.
In re Schrader, 22 F.3d 290 is a 1994 decision of the United States Court of Appeals for the Federal Circuit in which the court summarized and synthesized its precedents under the Freeman-Walter-Abele Test of patent eligibility. Under this test a key element is that the claimed invention is implemented with some type of hardware—that is, a particular machine. This was one of the last Federal Circuit decisions using that test.
Association for Molecular Pathology v. Myriad Genetics, Inc., 569 U.S. 576 (2013), was a Supreme Court case, which decided that "a naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated.” However, as a "bizarre conciliatory prize" the Court allowed patenting of complementary DNA, which contains exactly the same protein-coding base pair sequence as the natural DNA, albeit with introns removed.
Patentable subject matter in the United States is governed by 35 U.S.C. 101. The current patentable subject matter practice in the U.S. is very different from the corresponding practices by WIPO/Patent Cooperation Treaty and by the European Patent Office, and it is considered to be broader in general.

Lee, Supremes wrestle with business method, software patents, Ars Technica (Nov. 11, 2009) ("The patent office has been pushing this 'machine or transformation' test since at least the 1970s. The Supreme Court flirted with adopting it in its famous trio of software patent cases a generation ago. But ultimately, it stopped short, merely calling it a 'clue' to patent eligibility. The Federal Circuit, perhaps cowed by the recent string of unanimous Supreme Court reversals of its decisions, went further: it adopted the test as a substitute for the 'useful, concrete and tangible result' that the Supremes had ridiculed two years earlier.").

Metabolite Labs., Inc., 548 U.S. 124, 136–37 (2006), Justice Breyer, with whom Justice Stevens and Justice Souter joined, pointed out how the State Street test makes things patent-eligible that Supreme Court decisions had held patent-ineligible.
↑ However, one of Benson's rejected claims had a computer part (shift register) as a recited element, and the Court dismissed this machine limitation as meaningless from a practical standpoint.
↑ The significance of the observation about the machine claim format in State Street is uncertain, given the Federal Circuit's repeated holdings that machine and process claims must be treated alike for purposes of statutory subject matter analysis under § 101. Compare Schonfeld with AT&T Corp. v. Excel Communications, Inc., 172 F.3d 1352, 1357–58 (Fed. Cir. 1999) ("Whether stated implicitly or explicitly, we consider the scope of §101 to be the same regardless of the form — machine or process — in which a particular claim is drafted. In fact, whether the invention is a process or a machine is irrelevant. ... Furthermore, the Supreme Court's decisions in Diehr, Benson, and Flook, all of which involved method (i.e., process) claims, have provided and supported the principles which we apply to both machine- and process-type claims."; see also State Street, 149 F.3d at 1372 ("For the purposes of a § 101 analysis, it is of little relevance whether claim 1 is directed to a 'machine' or a 'process,'...").
↑ The Supreme Court's opinion in Bilski v. Kappos is more consistent with the majority opinion than the dissent. As explained by Justice Breyer in a concurring opinion, the Court was unanimous that the State Street opinion's "useful, concrete and tangible result" test was erroneous. As to the machine-claim point, the Supreme Court's opinion in Alice v. CLS Bank expressly held that saying "do it on a computer" did not make an otherwise abstract-idea claim patent eligible.
But when it comes to business methods, we see the killer statistics: prior to Alice, prosecutors overcame the non-final §101 rejections generally about 62% of the time, leading to final rejection rates in the 23-46% range; thus prosecutors had more or less even odds of getting over the rejection. What is shocking is that after Alice, the final rejection rate soared into the 90% range.
