ADAMS, RICHARD M. LEBOVITZ, and JEFFREY N. FREDMAN, Administrative Patent Judges. ADAMS, Administrative Patent Judge. DECISION ON APPEAL Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from Examiner’s decision to reject claims 9–16 (Non-Final Act.2 2). We have jurisdiction under 35 U.S.C. § 6(b). We REVERSE. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as “INSERM (INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE) of Paris, France; UNIVERSITE PAUL SABATIER TOULOUSE III of Toulouse, France; and CENTRE HOSPIT ALIER UNIVERSIT AIRE DE TOULOUSE of Toulouse, France” (Appellant’s August 26, 2019 Appeal Brief (Appeal Br.) 3). 2 Examiner’s March 27, 2019 Non-Final Office Action. Appeal 2020-002426 Application 15/869,438 2 STATEMENT OF THE CASE Appellant’s disclosure: [R]elates to a method for classifying a patient at risk for heart failure, wherein said method comprises the steps of (i) measuring the concentration of IGFBP2 in a sample obtained from said patient and (ii) comparing the concentration of IGFBP2 measured in step (i) to a control value derived from the concentration of IGFBP2 in samples from patients who are at particular stages of heart failure and/ or to a control value derived from the concentration of IGFBP2 in blood samples from healthy patients. (Spec.3 1:5–11). Appellant’s claims 9 and 12 are reproduced below: 9. A method of treating heart failure in a patient in need thereof, comprising the steps of: a) obtaining a biological sample from said patient; b) measuring the concentration of IGFBP2 in the sample obtained in step a); c) determining the severity of the heart failure depending on the concentration of IGFBP2 measured in step b); and d) administering to said patient diagnosed as having heart failure an appropriate medication for a subject suffering from heart failure depending on the severity of the heart failure as determined in step c). (Appeal Br. 19–20.) 12. The method according to claim 9, wherein the biological sample obtained in step a) is a urine sample. (Id.) 3 Appellant’s February 12, 2018 Specification. Appeal 2020-002426 Application 15/869,438 3 Grounds of rejection before this Panel for review: Claims 9–11 and 14 stand rejected under 35 U.S.C. § 103(a) as unpatentable over the combination Hassfeld,4 Ebrahim,5 and Todd.6 Claims 12, 13, 15, and 16 stand rejected under 35 U.S.C. § 103(a) as unpatentable over the combination Hassfeld, Ebrahim, Todd, and McPherson.7 Claims 9–16 stand provisionally rejected under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1, 4–9, 11, and 13–17 of copending Application 14/895,076. Claims 9–16 stand rejected under 35 U.S.C. § 101. OBVIOUSNESS: ISSUE Does the preponderance of evidence relied upon by Examiner support a conclusion of obviousness? FACTUAL FINDINGS (FF) FF 1. Hassfeld discloses a method, wherein patient blood samples were obtained and “serum levels for IGF1, IGF2, IGFBP2, IGFBP3, growth hormone and growth hormone binding protein were determined by specific radio-immunoassays” (Hassfeld 359; see Ans. 4). 4 Hassfeld et al., Insulin-like growth factor-binding proteins 2 and 3 are independent predictors of a poor prognosis in patients with dilated cardiomyopathy, 93 Heart 359–60 (2007). 5 Ebrahim et al., US 2006/0183681 A1, published Aug. 17, 2006. 6 Todd et al., US 2014/0206632 A1, published July 24, 2014. 7 McPherson et al., US 2015/0119269 A1, published Apr. 30, 2015. Appeal 2020-002426 Application 15/869,438 4 FF 2. Hassfeld discloses “that the growth hormone/IGF-system is differently altered in patients with [congestive heart failure (CHF)] due to different causes and might influence the course of the disease” (Hassfeld 359; see Ans. 4). FF 3. Hassfeld discloses “that low IGF1 and IGFBP3 levels and high IGFBP2 levels are associated with a worse prognosis in patients with CHF due to idiopathic dilated cardiomyopathy” (Hassfeld 359–360; see Ans. 4). FF 4. Examiner finds that Hassfeld fails to disclose “determining the severity of the heart failure depending on the concentration of the biomarker” (Ans. 4). FF 5. Ebrahim discloses that “[p]lasma concentrations of the fragments of pro [B-type natriuretic peptide (BNP)] are increased in patients with CHF and have been shown to accurately predict clinical severity and left ventricular ejection fraction as well as morbidity and mortality in patients” and that “this indicator of CHF disease severity has been used to diagnose and classify the severity of the congestive heart failure” (Ebrahim ¶¶ 1 and 5; see generally Ans. 5). FF 6. Ebrahim discloses that “the New York Heart Association classification of CHF, the mean concentrations of BNP progressively increase from stage I to IV . . . of congestive heart failure” (Ebrahim ¶ 5; see Ans. 5). FF 7. Examiner finds that the combination of Hassfeld and Ebrahim fails to disclose “the administration of medical care for a subject suffering from heart failure” (Ans. 5). FF 8. Examiner relies on Todd to disclose “that it is known and conventional in the art to treat those subjects with heart failure with an Appeal 2020-002426 Application 15/869,438 5 amount of angiotensin-converting enzyme inhibitor (see Ans. 5 (citing Todd ¶ 89)). FF 9. Examiner finds that the combination of Hassfeld, Ebrahim, and Todd fails to suggest obtaining a plasma or urine sample or that the biomarker “measurement is done by a set of antibodies or performed by ELISA” (Ans. 6). FF 10. Examiner relies on McPherson to disclose the use of urine or plasma samples “for detecting biomarkers such as IGFPB2,” “can be measured by sandwich immunoassay,” and “that ELISA’s can be utilized to measure the biomarker” (Ans. 6 (citing McPherson ¶¶ 13, 14, 30, 32, 44, 46–48, 55, and 84–86). ANALYSIS The rejection over Hassfeld, Ebrahim, and Todd: Examiner recognizes “that Hassfeld fails to specifically teach determining the severity of the heart failure depending on the concentration of the [IGFBP2] biomarker,” but finds that because Hassfeld specifically teaches that IGFP2 levels are higher when associated with a worse prognosis patients in CHF and one of ordinary skill in the art would recognize that the higher the level the worse the prognosis and thus one or ordinary skill in the art would look to known methods of classification and as shown by Ebrahim it is well known in the art to utilize the NYHA stages I-IV (NOTE: this is the same classification as claimed in current claim 10) with the progression of the concentration of a biomarker to classify the severity of heart failure and that it would have been obvious to one of ordinary skill in the art at the time the invention was made to incorporate NYHA stages with increased concentrations of IGFBP2 in the method of Hassfeld because Ebrahim et al shows that the classification by NYHA stages I-IV and progression of Appeal 2020-002426 Application 15/869,438 6 concentration of a biomarker is well known and conventional in the art. (Ans. 14–15.) Thus, based on the combination of Hassfeld, Ebrahim, and Todd, Examiner concludes that, at the time Appellant’s invention was made, it would have been prima facie obvious “to incorporate NYHA stages with increased concentrations of IGFBP2 in the method of Hassfeld because Ebrahim . . . shows that the classification by NYHA stages I-IV and progression of concentration of a biomarker is well known and conventional in the art” (Ans. 5). Examiner, therefore, reasons that “absent evidence to the contrary one of ordinary skill in the art would have a reasonable expectation of success incorporating classification stages such as taught by Ebrahim . . . into the method of Hassfeld” (id.). Examiner further concludes that, at the time Appellant’s invention was made, it would have been prima facie obvious to incorporate a treatment such as taught by Todd . . . into the modified method of Hassfeld because Todd . . . shows that it is known in the art that subjects suffering from heart failure are treated with a medication. Thus, one of ordinary skill in the art would have a reasonable expectation of success incorporating medication treatment into the modified method of Hassfeld. (Id.) We are not persuaded. As Peacock explains, Hassfeld does not provide a link of IGFBP2 to severity of heart failure and thus the person of ordinary skill in the art would not be motivated to include IGFBP2 in any method involving the determination of severity of heart failure, including any such method disclosed in Ebrahim . . . . Ebrahim relates to the use of natriuretic peptides as a biomarker for heart failure. Ebrahim does not mention IGFBP2. Due to the unpredictability of the art, one of ordinary skill in the art would not assume that since Appeal 2020-002426 Application 15/869,438 7 one disease marker (natriuretic peptides) may also be useful for determining disease severity, that any other potential disease marker would be useful for determining disease severity. (Peacock Decl.8 ¶ 6; see also Appeal Br. 14.) Stated differently, although Hassfeld discloses a binary association between high IGFBP2 levels and “a worse prognosis in patients with CHF due to idiopathic dilated cardiomyopathy” (FF 3), Examiner failed to establish an evidentiary basis on this record to support a conclusion that Hassfeld relates the severity of the heart failure to the concentration of IGFBP2 measured in patient’s biological sample such that a person of ordinary skill in this art would have found it prima facie obvious that IGFBP2 concentrations would progressively increase from CHF stage I to IV (see FF 3). Ebrahim’s disclosure relating to a different biomarker, BNP, fails to make up for this deficiency in Hassfeld (see FF 6 (Ebrahim discloses that “the New York Heart Association classification of CHF, the mean concentrations of BNP progressively increase from stage I to IV . . . of congestive heart failure.”)). We agree with Appellant’s contention that Examiner’s reliance on Todd, to disclose the treatment of subjects with heart failure, “does not compensate for the deficiencies [in the combination] of Hassfeld and Ebrahim” discussed above (Appeal Br. 16). The rejection over Hassfeld, Ebrahim, Todd and McPherson: Based on the combination of Hassfeld, Ebrahim, Todd, and McPherson, Examiner concludes that, at the time Appellant’s invention was made, it would have been prima facie obvious to substitute a plasma or urine 8 W. Franklin Peacock Declaration, signed February 15, 2019. Appeal 2020-002426 Application 15/869,438 8 sample, for the blood sample, in the method suggested by the combination of Hassfeld, Ebrahim, and Todd, “because McPherson et al teaches that it is known in the art to utilize samples such as serum, plasma and urine” and, therefore, “absent evidence to the contrary one of ordinary skill in the art would have a reasonable expectation of success incorporating plasma or urine as the sample in the modified method of Hassfeld” (Ans. 6). Examiner further concludes that, at the time Appellant’s invention was made, it would have been prima facie obvious “to substitute sandwich formats or ELISA tests such as taught by McPherson . . . for the immunoassay of Hassfeld because McPherson . . . shows that it is well known and conventional in the art to utilize sandwich assay formats and ELISA for the detection/measurement of biomarkers such as IGFBP2” (id. at 7). We are not persuaded. Examiner’s reliance on McPherson to disclose the use of urine or plasma samples “for detecting biomarkers such as IGFPB2,” “can be measured by sandwich immunoassay,” and “that ELISA’s can be utilized to measure the biomarker,” fails to make up for the deficiencies in the combination of Hassfeld, Ebrahim, and Todd discussed above (see FF 10; cf. Appeal Br. 16 (Appellant contends that “McPherson . . . does not compensate for the deficiencies” in the combination of Hassfeld, Ebrahim, and Todd)). CONCLUSION The preponderance of evidence relied upon by Examiner fails to support a conclusion of obviousness. Appeal 2020-002426 Application 15/869,438 9 The rejection of claims 9–11 and 14 under 35 U.S.C. § 103(a) as unpatentable over the combination of Hassfeld, Ebrahim, and Todd is reversed. The rejection of claims 12, 13, 15, and 16 under 35 U.S.C. § 103(a) as unpatentable over the combination of Hassfeld, Ebrahim, Todd, and McPherson is reversed. SUBJECT MATTER ELIGIBILITY: ISSUE Does the preponderance of evidence of record support Examiner’s finding that Appellant’s claimed invention is directed to patent-ineligible subject matter? PRINCIPLES OF LAW A. Section 101 An invention is patent-eligible if it claims a “new and useful process, machine, manufacture, or composition of matter.” 35 U.S.C. § 101. However, the U.S. Supreme Court has long interpreted 35 U.S.C. § 101 to include implicit exceptions: “[l]aws of nature, natural phenomena, and abstract ideas” are not patentable. E.g., Alice Corp. v. CLS Bank Int’l, 573 U.S. 208, 216 (2014). In determining whether a claim falls within an excluded category, we are guided by the Court’s two-part framework, described in Mayo and Alice. Id. at 217–18 (citing Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66, 75–77 (2012)). In accordance with that framework, we first determine what concept the claim is “directed to.” See Alice, 573 U.S. at 219 (“On their face, the claims before us are drawn to the concept of Appeal 2020-002426 Application 15/869,438 10 intermediated settlement, i.e., the use of a third party to mitigate settlement risk.”); see also Bilski v. Kappos, 561 U.S. 593, 611 (2010) (“Claims 1 and 4 in petitioners’ application explain the basic concept of hedging, or protecting against risk.”). Concepts determined to be abstract ideas, and thus patent ineligible, include certain methods of organizing human activity, such as fundamental economic practices (Alice, 573 U.S. at 219–20; Bilski, 561 U.S. at 611); mathematical formulas (Parker v. Flook, 437 U.S. 584, 594–95 (1978)); and mental processes (Gottschalk v. Benson, 409 U.S. 63, 67 (1972)). Concepts determined to be patent eligible include physical and chemical processes, such as “molding rubber products” (Diamond v. Diehr, 450 U.S. 175, 191 (1981)); “tanning, dyeing, making water-proof cloth, vulcanizing India rubber, smelting ores” (id. at 182 n.7 (quoting Corning v. Burden, 56 U.S. 252, 267–68 (1854))); and manufacturing flour (Benson, 409 U.S. at 69 (citing Cochrane v. Deener, 94 U.S. 780, 785 (1876))). In Diehr, the claim at issue recited a mathematical formula, but the Court held that “a claim drawn to subject matter otherwise statutory does not become nonstatutory simply because it uses a mathematical formula.” Diehr, 450 U.S. at 187; see also id. at 191 (“We view respondents’ claims as nothing more than a process for molding rubber products and not as an attempt to patent a mathematical formula.”). Having said that, the Court also indicated that a claim “seeking patent protection for that formula in the abstract . . . is not accorded the protection of our patent laws, and this principle cannot be circumvented by attempting to limit the use of the formula to a particular technological environment.” Id. (citation omitted) (citing Benson and Flook); see, e.g., id. at 187 (“It is now commonplace that Appeal 2020-002426 Application 15/869,438 11 an application of a law of nature or mathematical formula to a known structure or process may well be deserving of patent protection.”). If the claim is “directed to” an abstract idea, we turn to the second step of the Alice and Mayo framework, where “we must examine the elements of the claim to determine whether it contains an ‘inventive concept’ sufficient to ‘transform’ the claimed abstract idea into a patent- eligible application.” Alice, 573 U.S. at 221 (internal quotation marks omitted). “A claim that recites an abstract idea must include ‘additional features’ to ensure ‘that the [claim] is more than a drafting effort designed to monopolize the [abstract idea].’” Id. (alterations in original) (quoting Mayo, 566 U.S. at 77). “[M]erely requir[ing] generic computer implementation[] fail[s] to transform that abstract idea into a patent-eligible invention.” Id. B. USPTO Section 101 Guidance In January 2019, the U.S. Patent and Trademark Office (USPTO) published revised guidance on the application of § 101. 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50 (Jan. 7, 2019) (“Guidance”).9 “All USPTO personnel are, as a matter of internal agency management, expected to follow the guidance.” Id. at 51; see also October 2019 Update at 1. 9 In response to received public comments, the Office issued further guidance on October 17, 2019, clarifying the 2019 Revised Guidance. USPTO, October 2019 Update: Subject Matter Eligibility (the “October 2019 Update”) (available at https://www.uspto.gov/sites/default/files/ documents/peg_oct_2019_update.pdf). Appeal 2020-002426 Application 15/869,438 12 Under the Guidance and the October 2019 Update, we first look to whether the claim recites: (1) any judicial exceptions, including certain groupings of abstract ideas (i.e., mathematical concepts, certain methods of organizing human activity such as a fundamental economic practice, or mental processes) (“Step 2A, Prong One”); and (2) additional elements that integrate the judicial exception into a practical application (see MPEP §§ 2106.05(a)–(c), (e)–(h) (9th ed. Rev. 08.2017, Jan. 2018)) (“Step 2A, Prong Two”).10 Guidance, 84 Fed. Reg. at 52–55. Only if a claim (1) recites a judicial exception and (2) does not integrate that exception into a practical application, do we then look, under Step 2B, to whether the claim: (3) adds a specific limitation beyond the judicial exception that is not “well-understood, routine, conventional” in the field (see MPEP § 2106.05(d)); or (4) simply appends well-understood, routine, conventional activities previously known to the industry, specified at a high level of generality, to the judicial exception. Guidance, 84 Fed. Reg. at 52–56. ANALYSIS (Step 1) We first consider whether the claimed subject matter falls within the four statutory categories set forth in § 101, namely “[p]rocess, machine, 10 This evaluation is performed by (a) identifying whether there are any additional elements recited in the claim beyond the judicial exception, and (b) evaluating those additional elements individually and in combination to determine whether the claim as a whole integrates the exception into a practical application. See Guidance — Section III(A)(2), 84 Fed. Reg. at 54–55. Appeal 2020-002426 Application 15/869,438 13 manufacture, or composition of matter.” Guidance, 84 Fed. Reg. at 53–54; see 35 U.S.C. § 101. The method set forth in Appellant’s claims falls within the four statutory categories set forth in § 101 (see Appeal Br. 20). Therefore, we proceed to the next steps of the analysis. (Step 2A, Prong 1) Appellant’s claimed method comprises, inter alia, as step (c), the determination of “the severity of [a patient’s] heart failure depending on the concentration of IGFBP2” in a patient’s biological sample (see Appeal Br. 20). Examiner finds that Appellant’s “claims are directed to a naturally occurring correlation between the concentration of IGFBP2 in [a] patient having heart failure” (Ans. 7). We find no error in Examiner’s finding that Appellant’s claim recites a natural law (see id.). (Step 2A, Prong 2) Having determined that Appellant’s claims recite a judicial exception involving a natural law, the Guidance requires an evaluation as to whether the claim as a whole integrates the recited judicial exception into a practical application of the exception. See Guidance, 84 Fed. Reg. at 54. Steps (a) and (b) of Appellant’s claimed method require that a biological sample is obtained from a biological sample and that the IGFBP2 concentration in this sample is measured, respectively (see Appeal Br. 20). The collection and measurement of a component in a sample are insignificant extra-solution activities that are insufficient to confer patent eligibility. See, e.g., Guidance, 84 Fed. Reg. at 55, n. 31 (citing Mayo, 566 U.S. at 79). Step (d) of Appellant’s claimed method, however, requires the administration “to said patient diagnosed as having heart failure an Appeal 2020-002426 Application 15/869,438 14 appropriate medication for a subject suffering from heart failure depending on the severity of the heart failure as determined in step c)” of the claimed method (see Appeal Br. 20). The evidence of record establishes that those of ordinary skill in this art understand the appropriate medication that should be administered to those suffering from heart failure depending on the severity of the heart failure (see, e.g., Spec. 13–18; Todd ¶ 91 (“[T]reating the patient that has a risk of CHF, or has CHF, . . . [to] prevent CHF, prevent or slow the progression of CHF, and avoid or prolong hospital admission for CHF”)). As the Guidance explains that “an additional element that applies or uses a judicial exception to effect a particular treatment or prophylaxis for a disease or medical condition” is “an additional element (or combination of elements) [that] may have integrated the exception into a practical application.” See Guidance, 84 Fed. Reg. at 55 (footnotes omitted); see also id. n. 26 (citing Vanda Pharm. Inc. v. West-Ward Pharm. Int’l Ltd., 887 F.3d 1117, 1135 (Fed. Cir. 2018) (holding claims to the practical application of the natural relationships between iloperidone, CYP2D6 metabolism, and QTc prolongation to treat schizophrenia, not merely the recognition of those relationships, to be patent eligible at Mayo/Alice step 1 (USPTO Step 2A)), and USPTO Vanda Memorandum (discussing Vanda)); see also Appeal Br. 8–9. For the foregoing reasons, we are not persuaded by Examiner’s assertion that Appellant’s “administration step is not particular, and is instead merely instructions to ‘apply’ the exception in a generic way” and, thus, “the administration step does not integrate the mental analysis step into a practical application” (Ans. 13). On this record, we find that Appellant’s claims integrate the judicial exception into a practical application. Appeal 2020-002426 Application 15/869,438 15 (Step 2B) Even if Appellant’s claimed invention did not integrate the judicial exception into a practical application, as discussed above, we find that when the elements of Appellant’s claimed invention are considered individually and in combination, Appellant’s claims add a specific limitation beyond the judicial exception that is not “well-understood, routine, conventional” in the field. See Guidance, 84 Fed. Reg. at 52–56. Specifically, for the reasons discussed above with respect to the obviousness rejection, we find that Examiner failed to establish an evidentiary basis on this record to support a finding that the correlation between IGFBP2 concentration in a biological sample and severity of heart failure was well-understood, routine, convention in this field. CONCLUSION The preponderance of evidence of record fails to support Examiner’s finding that Appellant’s claimed invention is directed to patent ineligible subject matter. The rejection of claims 9–16 under 35 U.S.C. § 101 is reversed. OBVIOUSNESS-TYPE DOUBLE PATENTING: Appellant does not contest Examiner’s provisional rejection of Appellant’s claims 9–16 under the judicially created doctrine of obviousness-type double patenting as being unpatentable over claims 1, 4–9, 11, and 13–17 of co-pending Application 14/895,076 (see Appeal Br. 19). Instead, Appellant contends that it “will address this issue once the final disposition of the present claims and/or those of 14/895,076 is determined, e.g. by filing a Terminal Disclaimer if necessary” (id.). Stated differently, Appeal 2020-002426 Application 15/869,438 16 Appellant waived any appeal of this rejection. Therefore, we decline to address the merits of this provisional obviousness-type double patenting rejection. See In re Moncla, 95 USPQ2d 1884, 1885 (BPAI 2010) (precedential).
