SQUIRE, AVELYN M. ROSS, and JANE E. INGLESE Administrative Patent Judges. ROSS, Administrative Patent Judge. DECISION ON APPEAL1 Appellant2 appeals under 35 U.S.C. § 134(a) from a rejection of claims 1–30, which constitute all the claims pending in this application. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 In our Decision we refer to the Specification filed January 28, 2015 (“Spec.”), the Final Office Action appealed from dated February 8, 2018 (“Final Act.”), the Appeal Brief filed June 11, 2018 (“Appeal Br.”), and the Examiner’s Answer dated September 19, 2018 (“Ans.”). 2 We use the word Appellant to refer to “applicant” as defined in 37 C.F.R. § 1.42(a). According to Appellant, Statoil Gulf Services LLC is the real party in interest. Appeal Br. 1. Appeal 2019-002871 Application 14/607,974 2 STATEMENT OF THE CASE The subject matter on appeal relates to systems and methods for predicting pore pressure and providing “a warning if a high overpressure regions is being drilled.” Spec. 1. According to the Specification, [w]hen a sediment is buried or compacted at a relatively high depositional rate, fluid may become trapped in pores within the resulting structure. Typically, compaction and dewatering of silts or clays is much faster than compaction of sand lithology. The compaction of silts or clays lowers the permeability of these sediments and, in turn, delays further the dewatering of sand layers that may be present below the clays. Fluid trapped in a sand formation in this manner exerts pressure (defined as pore pressure) on the surrounding formation. Formations in which pore pressure exceeds hydrostatic pressure at a given depth are referred to as overpressured. Id. And, when drilling in an overpressured formation, if the mud weight is not high enough, the pore pressure can move formation fluids into the bore hole or cause borehole collapse. Id. at 2. Therefore, according to Appellant, to ensure safe and cost effective drilling, it is advantageous to predict jumps in pore pressure ahead of the drill bit. Id. (explaining that “knowledge of accurate pore pressure is crucial when drilling a well in order to ensure success of the drilling operation.”). Claim 1, reproduced below, is illustrative of the claimed subject matter: 1. A method for predicting jumps in pore pressure of a subsurface, comprising: obtaining a porosity and a resistivity log value while drilling; dividing, using a processor, a cross plot of the porosity and the resistivity log values into two regions where a split of the two regions is based on the following (I): Appeal 2019-002871 Application 14/607,974 3 wherein R is the resistivity log value and Ø is the porosity log value; averaging the obtained porosity and resistivity log values in the subsurface within a set interval to obtain a representative value of resistivity and porosity for the subsurface within the set interval; rejecting intervals where the subsurface is a sand formation that is not water saturated and rejecting porosity values that are larger than a specified threshold; and giving a first warning of a high overpressure region if the representative value of resistivity at the representative value of porosity is lower than Claims Appendix 1 (“Claims App.”). Claims 11 and 21, the remaining independent claims, are directed to a non-transitory computer readable storage medium having instructions for performing the method and a downhole tool including a processor and memory for performing the method, respectively. Id. at 3, 5. REJECTION The Examiner maintains the rejection of claims 1–30 under 35 U.S.C. § 101 as directed to non-statutory subject matter. Final Act. 8.3 Appellant argues independent claims 1 and 21 and does not separately argue independent claim 11 or the dependent claims. See generally Appeal Br. We, therefore, limit our discussion to claims 1 and 21 and the remaining claims stand or fall with the claims from which they depend. 37 C.F.R. § 41.37(c)(1)(iv) (2016). 3 The Examiner withdraws the remaining rejections to claims 1–30 under 35 U.S.C. §§ 112 (a) and (b) and 35 U.S.C. § 103. Ans. 3. Appeal 2019-002871 Application 14/607,974 4 OPINION We review the appealed rejection for error based upon the issues Appellant identifies and in light of the arguments and evidence produced thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential) (cited with approval in In re Jung, 637 F.3d 1356, 1365 (Fed. Cir. 2011) (“[I]t has long been the Board’s practice to require an applicant to identify the alleged error in the examiner’s rejections . . . .”)). After considering the evidence presented in this Appeal and each of Appellant’s arguments, we are not persuaded that Appellant identifies reversible error. Thus, we affirm the Examiner’s rejection and do so for the reasons expressed in the Final Office Action and the Answer. We add the following. Patent Eligible Subject Matter Section 101 of the Patent Act provides that “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof” is patent eligible. 35 U.S.C. § 101. However, the Supreme Court has long recognized certain exceptions to this section including “[l]aws of nature, natural phenomena, and abstract ideas.” Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 216 (2014). To determine whether a claim falls within an excluded category, the Supreme Court’s two-step framework, described in Mayo and Alice, guides us. 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” and whether that concept is directed to an abstract idea. See Alice, 573 U.S. at 219 (“On their face, the claims before us are drawn to the concept of intermediated settlement, i.e., the use of a third party to mitigate settlement risk.”); see also Appeal 2019-002871 Application 14/607,974 5 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 methods for 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, 69 (1972)). However, not every claim that recites a mathematical formula is patent ineligible. Diamond v. Diehr, 450 U.S. 175, 176 (1981). If the claim is “directed to” an abstract idea, we then 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 (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. (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. The USPTO recently published revised guidance on the application of § 101. See Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50 (Jan. 7, 2019) (“2019 Guidance”). Under Step 1 of the 2019 Guidance, we determine whether the claimed subject matter falls within the four statutory categories: process, machine, manufacture, or composition of matter. Step 2A of the 2019 Guidance is two-pronged, under which we look to whether the claim recites: Appeal 2019-002871 Application 14/607,974 6 (1) any judicial exception, 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); and (2) additional elements that integrate the judicial exception into a practical application (see MPEP § 2106.05(a)–(c), (e)–(h)). See 2019 Guidance at 54–55. Only if a claim (1) recites a judicial exception and (2) does not integrate that exception into a practical application, do we then look 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)); (4) or simply appends well-understood, routine, conventional activities previously known to the industry, specified at a high level of generality, to the judicial exception. See 2019 Guidance at 56. Step 1 (statutory category) As an initial matter, the claims must recite at least one of four recognized statutory categories, namely, machine, process, article of manufacture, or composition of matter. MPEP § 2106(I); see 35 U.S.C. § 101. Claim 1 recites a method. Claims App. 1. Furthermore, there is no dispute that claim 1 falls within a statutory category. See Final Act. 8 (“Claims 1–30 all pertain to statutory category.”). Step 2A, Prong 1 (recites a judicial exception) According to Step 2A of the 2019 Guidance, we first consider whether the Examiner erred in determining that the claim recites a judicial exception. The Examiner determines that claims 1–30 are each directed to an abstract idea. Final Act. 8. In particular, the Examiner identifies “dividing, using a Appeal 2019-002871 Application 14/607,974 7 processor, a cross plot of the porosity and the resistivity log values into two regions . . . ,” “averaging the obtained porosity and resistivity log values . . . within a set interval to obtain a representative value of resistivity and porosity,” and “rejecting intervals where the subsurface is a sand formation that is not water saturated and rejecting porosity values that are larger than a specified threshold” as abstract. Id. The Examiner explains that the identified concepts have been determined to be abstract ideas by the courts and refer to limitations that “are similar to collecting information, analyzing, and provid[ing] the result after analyzing it or performing mathematical correlations.” Id. at 8–9. Appellant contends that the claims are not directed to a judicial exception, but instead “recite a specific and concrete technological implementation to solve a technological problem, and realizes a technical improvement.” Appeal Br. 12. Appellant asserts that in Electric Power Group, cited by the Examiner, “the claims were directed to collecting and analyzing data at a high degree of generality without any specific implementations of those steps” whereas here, “the claimed invention solves a problem by raising an alarm during the drilling based on a very specific solution of how the data is analyzed.” Id. We are unpersuaded by Appellant’s arguments, and instead agree with the Examiner that the claims recite abstract ideas, for the reasons that follow. Applying the construct set forth in the 2019 Guidance, we first determine whether claim 1 recites a judicial exception to patent eligibility. 2019 Guidance at 54. The 2019 Guidance identifies three judicially-excepted groupings: Appeal 2019-002871 Application 14/607,974 8 (a) mathematical concepts including “mathematical relationships, mathematical formulas or equations, mathematical calculations”; (b) certain methods of organizing human activity, such as “fundamental economic principles or practices,” “commercial or legal interactions,” and “managing personal behavior or relationships or interactions between people”; and (c) mental processes including “observation, evaluation, judgment, [and] opinion.” Id. at 52. Based on existing Supreme Court and Federal Circuit precedent, the 2019 Guidance has identified “mental processes” as including “concepts performed in the human mind (including an observation, evaluation, judgment, opinion).” Id. at 53. The “mental processes” judicial exception also includes concepts that can be performed by a human with a pen and paper as well as those that can be performed entirely in the mind. See October 2019 Update: Subject Matter Eligibility (“2019 Update”) at 9 (“a claim that encompasses a human performing the step(s) mentally with the aid of a pen and paper recites a mental process”); Intellectual Ventures I LLC v. Symantec Corp., 838 F.3d 1307, 1318 (Fed. Cir. 2016) (finding claims to be patent ineligible because “with the exception of generic computer implemented steps, there is nothing in the claims themselves that foreclose them from being performed by a human, mentally or with pen and paper.”). And “merely presenting the results of abstract processes of collecting and analyzing information, without more (such as identifying a particular tool for presentation), is abstract as an ancillary part of such collection and analysis.” Electric Power Group, LLC v. Alstom S.A., 830 F.3d 1350, 1354 (Fed. Cir. 2016) (citing cases including Parker v. Flook, 437 U.S. 584, 98 S.Ct. 2522 (1978), and Gottschalk v. Benson, 409 U.S. 63, Appeal 2019-002871 Application 14/607,974 9 93 S.Ct. 253 (1972)). The claims here recite abstract ideas according to these principles. Independent claim 1 recites, inter alia, “dividing . . . a cross plot of the porosity and the resistivity log values . . . based on” an equation, “averaging the obtained porosity and resistivity log values . . . within a set interval,” and “rejecting intervals where the subsurface is a sand formation that is not water saturated and rejecting porosity values that are larger than a specified threshold,” each of which involve mental processes or mathematical concepts, i.e., abstract ideas. Claims App. 1. By way of example, the Specification explains that the “dividing” step involves dividing a cross plot of porosity and resistivity log values into two regions based on the following mathematical relationship: where R is the resistivity log value and is the porosity log value. Spec. 3. In the “averaging” step, the resistivity and porosity log values are then averaged based on an identified interval (e.g., distance) in order to obtain a representative value for that interval. Id. According to the “discarding” step, when the sand is not properly saturated and where the porosity exceeds a certain threshold, that interval is discarded. Id. at 3–4. Thus, the Specification makes clear that these limitations recite mental processes because they analyze measured values to produce additional data and select portions of that data to form conclusions, which are concepts that can be performed by a human with a pen and paper as well as those that can be performed entirely in the mind. 2019 Update 7 (citing Electric Power Group, 850 F.3d at 1355); see Intellectual Ventures I LLC v. Capital One Appeal 2019-002871 Application 14/607,974 10 Fin. Corp., 850 F.3d 1332, 1340 (Fed. Cir. 2017) (“an invention directed to collection, manipulation and display of data was an abstract process”); see also SAP Am., Inc. v. InvestPic, LLC, 898 F.3d 1161, 1168 (Fed. Cir. 2018)(“We have explained that claims focused on ‘collecting information, analyzing it, and displaying certain results of the collection and analysis’ are directed to an abstract idea”). In view of the foregoing, we do not discern a reversible error in the Examiner’s determination that the claims recite abstract subject matter. Step 2A, Prong 2 (integration into a practical application) Having determined that claim 1 recites a judicial exception, i.e., an abstract idea, our analysis under the guidance turns to whether the claims include additional elements that integrate the abstract idea into a practical application. 2019 Guidance at 54. In other words, we must now determine whether the claims are directed to the abstract idea itself or whether it is instead directed to some technological implementation or application of, or improvement to, the abstract idea such that there is a meaningful limit imposed on the judicial exception. See id. at 54–55; see also, e.g., Alice, 573 U.S. at 223, discussing Diamond v. Diehr, 450 U.S. 175 (1981). The Examiner finds that the additional elements “are not sufficient to make the claim as a whole amount to significantly more that the abstract idea itself.” Final Act. 9. For example, the Examiner finds that the step of obtaining a porosity and resistivity log value and giving a warning of high over pressure is well-understood and routine and is simply manipulating the data. Id. Appellant argues that “the independent claims provide a method, CRM [computer readable memory], or downhole tool to give a warning Appeal 2019-002871 Application 14/607,974 11 of increased pore pressure during a drilling operation” and “does not monopolize the general idea of analyzing pore pressure data and does not preempt other alternatives.” Appeal Br. 15–16. On this record, we are unpersuaded by Appellant’s arguments. Here, the additional elements beyond the identified abstract mental processes include: “obtaining a porosity and resistivity log value while drilling,” a processor, and “giving a first warning of a high overpressure region.” See Claims App. 1. The “obtaining” and “giving a warning” steps amount to insignificant extra-solution activity that merely collects the data and then displays, through a warning, the result of the abstract idea recited in Appellant’s claims. 2019 Guidance (citing Mayo, 566 U.S. at 79 (concluding that additional element of measuring metabolites of a drug administered to a patient was insignificant extra-solution activity, which was insufficient to confer patent eligibility) and Flook, 437 U.S. at 590 (step of adjusting an alarm limit based on the output of a mathematical formula was “post-solution activity” and did not render method patent eligible). Therefore, neither step integrates the abstract idea into a practical application. The last limitation of claim 1, i.e., a processor, similarly does not integrate the abstract idea into a practical application. Our guidance instructs that when “an additional element . . . merely includes instructions to implement an abstract idea on a computer or merely uses a computer as a tool to perform an abstract idea,” such implementation does not integrate the exception into a practical application. 2019 Guidance 55. Appellant additionally asserts that claim 21, directed to a downhole tool, is not an abstract idea because it “does not tie up the use of the Appeal 2019-002871 Application 14/607,974 12 mathematical relationships generally.” Appeal Br. 16. According to Appellant, the instant claim is similar to the “robotic arm assembly” described in the 2014 Interim Examination Guidelines and is clearly not an abstract idea. Id. On this record, we disagree. Claim 21 applies the abstract idea to “a downhole tool” by virtue of the preamble. Claims App. 5–6. In particular, Claim 21 recites: 21. A downhole tool configured to perform a method of predicting jumps in pore pressure of a subsurface the downhole tool: a processor; a memory comprising software instructions for enabling the downhole tool under control of the processor to: obtain a porosity and a resistivity log value while drilling; divide a cross plot of the porosity and the resistivity log values into two regions where a split of the two regions is based on the following (I): wherein R is the resistivity log value and 0 is the porosity log value; average the obtained porosity and resistivity log values in the subsurface within a set interval to obtain a representative value of resistivity and porosity for the subsurface within the set interval; reject intervals where the subsurface is a sand formation that is not water saturated and reject porosity values that are larger than a specified threshold; and give a first warning of a high overpressure region if the representative value of resistivity at the representative value of porosity is lower than Appeal 2019-002871 Application 14/607,974 13 Id. Our guidance explains that “the claimed invention may integrate the judicial exception into a practical application by demonstrating that it improves the relevant existing technology although it may not be an improvement over well-understood, routine, conventional activity. 2019 Update 12–13. Here, however, the recited “downhole tool” is nothing more than a processor and instructions that perform the recited judicial exception and does not reflect an improvement to the processor’s functioning. Thus, claim 21 “merely includes instructions to implement an abstract idea on a computer, or merely uses a computer as a tool to perform an abstract idea,” which does not integrate the abstract idea into a practical application. 2019 Guidance 55. In evaluating these additional elements, we conclude that the claims as a whole do not integrate the recited mental process steps into a practical application. Step 2B (inventive concept) Consistent with the 2019 Guidance, “[i]t is possible that a claim that does not ‘integrate’ a recited judicial exception is nonetheless patent eligible.” 2019 Guidance 56. In step 2B, we consider the elements of the claim, both individually and as an ordered combination, to assess whether the additional elements transform the nature of the claim into patent-eligible subject matter. Id.; see Content Extraction & Transmission LLC v. Wells Fargo Bank, 776 F.3d 1343, 1347 (Fed. Cir. 2014). “An inventive concept that transforms the abstract idea into a patent-eligible invention must be significantly more than the abstract idea itself, and cannot simply be an instruction to implement or apply the abstract idea on a computer.” Bascom Global Internet Servs., Inc. v. AT&T Mobility LLC, 827 F.3d 1341, 1349 Appeal 2019-002871 Application 14/607,974 14 (Fed. Cir. 2016). In this context, we consider whether the additional elements simply append “well-understood, routine, and conventional” elements, particularly at a high level of generality to the judicial exception. 2019 Guidance 56. “Whether something is well-understood, routine, and conventional to a skilled artisan at the time of the patent is a factual determination.” Berkheimer v. HP Inc., 881 F.3d 1360, 1369 (Fed. Cir. 2018). Here, we determine that the claims do not recite “significantly more” than an abstract idea. The Examiner finds that “obtaining a porosity and a resistivity log value while drilling is well-understood, generic and routine in the art (i.e., using a conventional tool to collect data while drilling) and giving a first warning of a high overpressure region . . . is the result after manipulating the data (i.e., output the data).” Final Act. 4; see also id. at 9 (determining the claims use well-understood, generic, and routine techniques). The Specification does not describe the combination of gathering information, processing that information, and then outputting information in the form of a warning as anything other than obtaining in a conventional manner and utilizing generic equipment to process and output the data. See generally Spec.; see also id. at 6, 7 (describing generic use of “instructions” or a “processor” to perform the recited steps). Further, as the Examiner finds, the prior art of record describes obtaining porosity and resistivity log data as indicative of the pore pressure in a subsurface (Final Act. 10–12 (citing Nguyen4 ¶¶ 5–6, 14–16 and Dunham5, col. 4, ll. 19–45 4 Ha Dinh Nguyen, US 2015/0267527 A1, published September 24, 2015 (“Nguyen”). 5 Lanny L. Dunham, US 5,992,228, issued November 30, 1999 (“Dunham”). Appeal 2019-002871 Application 14/607,974 15 and col. 3, ll. 5–20)) and outputting a warning of a high overpressure region. Final Act. 12 (citing DeBree6 ¶¶ 26, 45, 48–49, 56). Finally, Appellant does not direct our attention to any record evidence that would show the additional method steps or structural elements are more than well-understood, routine, and conventional. See generally Appeal Br. We acknowledge Appellant’s assertion that “the claimed invention constitutes a measurement process of a real world parameter[, that is,] . . . [it] gives a warning of a jump in pore pressure during a drilling operation . . . [and therefore,] is not an abstract idea but involves a real-world implementation.” Appeal Br. 13. But, the Examiner additionally finds that “a downhole tool giving a warning of a jump in pore pressure during drilling operation is well-understood, routine, and conventional as shown in the prior art of record.” Ans. 5; see also DeBree ¶¶ 26 (describing the method as useful for obtaining “an early warning during a drilling operation of a sudden abnormality in the pore fluid pressure in the region that is about to be drilled”), 56 (explaining that an abrupt increase in stress rate “can be interpreted as a warning for the upcoming pressure boundary”). Appellant does not challenge the Examiner’s additional factual findings.7 We therefore adopt these findings as fact. Cf. In re Kunzmann, 326 F.2d 424, 425 n.3 (CCPA 1964) (a finding not shown by the Appellant to be erroneous may be accepted as fact). Furthermore, the abstract subject matter itself—i.e., the mental process of measuring a parameter—cannot supply the inventive concept 6 DeBree, et al., US 2007/0083332 A1, published April 12, 2007 (“DeBree”). 7 We observe that no reply brief was filed by Appellant. Appeal 2019-002871 Application 14/607,974 16 under Step 2B. See BSG Tech. LLC v. BuySeasons, Inc., 899 F .3d 1281, 1290 (Fed. Cir. 2018) (“It has been clear since Alice that a claimed invention’s use of the ineligible concept to which it is directed cannot supply the inventive concept that renders the invention ‘significantly more’ than that ineligible concept.”); Berkheimer, 890 F.3d 1369, 1374 (Fed. Cir. 2018) (Moore, J., concurring) (“Berkheimer . . . leave[s] untouched the numerous cases from [the Federal Circuit] which have held claims ineligible because the only alleged ‘inventive concept’ is the abstract idea.”). Therefore, after considering the elements both individually and as an ordered combination. we conclude that the elements do not amount to significantly more than the abstract idea itself and is patent ineligible. For the reasons discussed above and those the Examiner provides, we do not find that the Examiner reversibly erred and, therefore, sustain the rejection of claims 1–30. CONCLUSION Appellant failed to identify a reversible error in the Examiner’s rejection of claims 1–30 under 35 U.S.C § 101 as directed to non-statutory subject matter. DECISION For the above reasons, the Examiner’s rejection of claims 1–30 is affirmed as follows: Claims Rejected Basis Affirmed Reversed 1–30 § 101 Eligibility 1–30 Appeal 2019-002871 Application 14/607,974 17 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv).
