ADAMS, RICHARD M. LEBOVITZ, and JEFFREY N. FREDMAN, Administrative Patent Judges. FREDMAN, Administrative Patent Judge. DECISION ON APPEAL This is an appeal 1,2 under 35 U.S.C. § 134 involving claims to a method of determining whether a culture in a vessel contains a plurality of microorganisms. The Examiner rejected the claims as directed to non- statutory subject matter. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 Appellant identifies the Real Party in Interest as Becton, Dickinson and Company (App. Br. 1 ). 2 We have considered and herein refer to the Specification of Aug. 17, 2010 ("Spec."); Final Office Action of Mar. 23, 2016 ("Final Action"); Appeal Brief of Sept. 14, 2016 ("App. Br."); Examiner's Answer of Dec. 2, 2016 ("Ans.") and Reply Brief of Feb. 1, 2017 (Reply Br.). Appeal2017-007200 Application 12/918,019 Statement of the Case Background "Rapid and reliable detection of microorganisms in a culture, such as a blood culture, is among the most important functions of the clinical microbiology laboratory" (Spec. 1: 10-11 ). The "present invention describes a data transformation that can be applied to metabolic or cell growth data in a way that provides confidence that a culture in a vessel is infected with a microorganism (high confidence positive) and essentially eliminates the potential for false negative determinations" (Spec. 2:20-23). The Claims Claims 1, 3-25, 27-31, 33, 38, 40-43, 46-49, and 53-55 are on appeal. Claim 1 is representative and reads as follows: 1. A method of determining whether a culture in a vessel contains a plurality of microorganisms, the method comprising: i) providing a vessel with a culture disposed therein, the vessel further comprising a sensor in communication with the culture; ii) obtaining a signal from the sensor, the signal being a measure of an initial biological state of the culture; iii) incubating the culture disposed in the vessel; iv) obtaining signals from the sensor, the signal being a measure of the biological state of the culture during incubation; (A) calculating a normalization relative value for each respective measurement in a plurality of measurements of a biological state of the culture in the vessel, taken at different time points between a first time point and a second time point, between (i) the respective measurement and (ii) an initial biological state of the culture taken at an initial time point, thereby forming a plurality of normalization relative values for 2 Appeal2017-007200 Application 12/918,019 each of a plurality of predetermined fixed interval of time points; (B) determining, for each respective predetermined fixed interval of time points between the first time point and the second time point, a first derivative of the normalization relative values for measurements of the biological state in the respective predetermined fixed interval of time points, thereby forming a plurality of rate transformation values, wherein the plurality of rate transformation values comprises a plurality of sets of rate transformation values, wherein each respective set of rate transformation values in the plurality of sets of rate transformation values is for a different set of contiguous time points between the first time point and the second time point; (C) computing, for each respective set of rate transformation values in the plurality of sets of rate transformation values, an average relative transformation value as a measure of central tendency of each of the rate transformation values in the respective set of rate transformation values, thereby computing a plurality of average relative transformation values; (D) obtaining (i) a first result based on a determination of whether any average relative transformation value in the plurality of average relative transformation values exceeds a first threshold value or (ii) a second result based on a determination of whether an extent of growth exhibited by the culture exceeds a second threshold value; (E) using the first result or the second result to determine whether the culture in the vessel contains the plurality of microorganisms; and (F) outputting the first result, the second result, or a determination of whether the culture in the vessel contains the plurality of microorganisms to a user interface device, a monitor, a computer-readable storage medium, a computer- readable memory, or a local or remote computer system; or displaying the first result, the second result, or the 3 Appeal2017-007200 Application 12/918,019 determination of whether the culture in the vessel contains the plurality of microorganisms. The Re} ection The Examiner rejected claims 1, 3-25, 27-31, 33, 38, 40-43, 46-49, and 53-55 under 35 U.S.C. § 101 as directed to non-statutory subject matter (Final Act. 2--4). The Examiner finds that the claims on appeal are directed to patent- ineligible subject matter. Specifically, the Examiner finds that the claims are directed to a "mathematical process of calculating a normalization relative value for a plurality of measurements" and that "[ s ]uch a mathematical process is an abstract idea" (Final Act. 2-3). The Examiner finds that the "claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception" (id. 3). The Examiner cites Pitner3 to establish that steps including "providing a vessel with a culture and sensor, obtaining a signal from the sensor, incubating the culture in the vessel, and obtaining signals from the sensor as a measure of the biological state of the culture" "are well-known, conventional and routine data-gathering steps" (id.). The Examiner reached these conclusions by applying the test set out in Mayo Collaborative Services v. Prometheus Laboratories, Inc., 566 U.S. 66 (2012) (Ans. 2--4) based on the two-step Alice framework. Alice Corp. Pty. Ltd. v. CLS Banklnt'l, 134 S. Ct. 2347, 2355 (2014). Appellant contends that the claims are not directed to an abstract idea, that Federal Circuit caselaw does not support the Examiner's position, that the claims do not preempt all uses of the abstract idea, and that the claims 3 Pitner et al., US 2002/0155424 Al, published Oct. 24, 2002. 4 Appeal2017-007200 Application 12/918,019 include additional elements or something more that transforms the nature of the claims into a patent-eligible application (App. Br. 8-22). Analysis To determine whether a claim is invalid under§ 101, we employ the two-step Alice framework. In Alice step one, we ask whether the claims are directed to a patent ineligible concept, such as an abstract idea or law of nature. Alice, 134 S.Ct. at 2355; Mayo, 566 U.S. at 75-77; Ariosa Diagnostics, Inc. v. Sequenom, Inc., 788 F.3d 1371, 1375 (Fed. Cir. 2015). While method claims are generally eligible subject matter, method claims that are directed only to abstract ideas and/or natural phenomena are directed to patent ineligible concepts. Ariosa, 788 F.3d at 1376. In Alice step two, we examine the elements of the claims to determine whether they contain an inventive concept sufficient to transform the claimed naturally occurring phenomena into a patent-eligible application. Mayo, 566 U.S. at 71-72 ( quoting Alice, 134 S.Ct. at 2355). Alice Step One Claim 1 is directed to an abstract idea. In particular, the recited steps of "(A) calculating a normalization relative value for each respective measurement"; "(B) determining ... a first derivative of the normalization relative values . . . thereby forming a plurality of rate transformation values"; "(C) computing, for each respective set of rate transformation values ... an average relative transformation value"; and "(D) obtaining (i) a first result based on a determination of whether any average relative transformation value ... exceeds a first threshold value" all involve categorizing and/or analyzing information. 5 Appeal2017-007200 Application 12/918,019 Information as such is an intangible .... Accordingly, we have treated collecting information, including when limited to particular content ( which does not change its character as information), as within the realm of abstract ideas .... In a similar vein, we have treated analyzing information by steps people go through in their minds, or by mathematical algorithms, without more, as essentially mental processes within the abstract-idea category Electric Power Group, LLC v. Alstom S.A., 830 F.3d 1350, 1353-54 (Fed. Cir. 2016) (internal citations omitted)) Additionally, the Federal Circuit in Electric Power Group stated that the "advance they purport to make is a process of gathering and analyzing information of a specified content, then displaying the results, and not any particular assertedly inventive technology for performing those functions" (id. at 1354). Here, Appellant acknowledges the advancement is the process of analyzing information; specifically, Appellant acknowledges "the present invention describes a data transformation that can be applied to metabolic or cell growth data in a way that provides confidence that a culture in a vessel is infected" (Spec. 2:20-22). Also, the Specification teaches "[a]lgorithms are then applied to the sequence of signal data that are designed to recognize signal changes with time that are indicative of the presence of growing microorganisms" (Spec. 11: 5-7). In Digitech, the Federal Circuit stated that"[ w ]ithout additional limitations, a process that employs mathematical algorithms to manipulate existing information to generate additional information is not patent eligible. 'If a claim is directed essentially to a method of calculating, using a mathematical formula, even if the solution is for a specific purpose, the claimed method is nonstatutory'" Digitech Image Technologies, LLC v. 6 Appeal2017-007200 Application 12/918,019 Electronics for Imaging, Inc., 758 F.3d 1344, 1351 (Fed. Cir. 2014). Here, the process employs mathematical algorithms to manipulate existing metabolic or cell growth data to generate additional information regarding the presence of a microorganism and therefore is not patent eligible. Moreover, the "calculating", "determining", "computing" and "obtaining" steps are the type of work that can be performed mentally and therefore are abstract ideas. As the Federal Circuit explained, "methods which can be performed mentally, or which are the equivalent of human mental work, are unpatentable abstract ideas-the 'basic tools of scientific and technological work' that are open to all"' CyberSource Corp. v. Retail Decisions, Inc., 654 F.3d 1366, 1371, (Fed. Cir. 2011) (citing Gottschalkv. Benson, 409 U.S. 63 (1972)). This case is distinguishable, for example, from cases like Diamond v. Diehr, 450 U.S. 175 (1981), because in Diehr, an algorithm was used to control the change in state of rubber in a curing process. In re Diehr, 602 F .2d 982, 983-84 (CCP A 1979). The algorithm calculated the Arrhenius equation for the reaction time during the cure to determine when the compound was cured and to automatically open the press when the cured state was achieved. Id. In the rejected claims, the recited algorithm is not used for a physical step that completes a product when a change of state is complete as it was in Diehr. Rather, in the rejected claims, the algorithm is utilized to analyze data obtained by measuring signals in culture vessels, but no final physical step analogous to opening the press after curing is present. Instead, the final "using" and "outputting" clause in the instant claims "tell the relevant audience about the laws while trusting them to use those laws appropriately where they are relevant to their decisionmaking." Mayo, 566 7 Appeal2017-007200 Application 12/918,019 U.S. at 78. Thus, the algorithm does not tell when the change of state is complete and to perform a manipulative step based on it as in Diehr. Because the claims are directed to an abstract idea, we tum to the second step of the Alice framework. Alice Step Two In Alice step two, we examine the elements of the claims to determine whether they contain an inventive concept sufficient to transform the claimed abstract idea into a patent-eligible application. Mayo, 566 U.S. at 71-72 (quoting Alice, 134 S.Ct. at 2355). We must consider the elements of the claims both individually and as an ordered combination to determine whether the additional elements transform the nature of the claims into a patent-eligible concept. Ariosa, 788 F.3d at 1375. The Specification acknowledges that "several different culture systems and approaches are available to laboratories. For example, the BACTEC® radiometric and nonradiometric systems (Becton Dickenson Diagnostic Instrument Systems, Sparks, Maryland) are often used for this task" (Spec. 1 :31 to 2: 1 ). The Specification also acknowledges that measurements of the samples are performed using known, prior art, techniques such as colorimetric assays (see Spec. 19:10-16), fluorometric assays (see Spec. 24--28), and infrared assays (see Spec. 20:5-9). Thus, the Specification acknowledges that measuring bacterial culture samples using a variety of analytical approaches is routine and conventional and that "[c]urrently, the presence of biologically active agents ... is determined using culture vials" that are "incubated and monitored for microorganism growth" (Spec. 1: 12-16). 8 Appeal2017-007200 Application 12/918,019 The Examiner further cites Pitner as a prior art reference to evidence that the structural elements aside from the mathematical steps in claim 1 "are well-known, conventional and routine data-gathering steps" (Ans. 3). Specifically, Pitner teaches "a quick, easy, and unambiguous method for the measurement and/or detection of respiring aerobic microorganisms ... by measurement or visual observation of luminescence" (Pitner ,r 51 ). Pitner teaches step of (i) providing a vessel with a culture where "TSB broth ... containing about 0.05 CPU/ml E. coli . .. was added to one of the flasks." (Pitner ,r 105). Pitner then teaches the step of (ii) obtaining a signal from a sensor where "fiber optic probe allowed the fluorescence from the flasks to be measured" (Pitner ,r 105). Pitner next teaches the step of (iii) incubating the culture where "the flasks were incubated at 37° C." (Pitner ,r 105). Pitner teaches a next step of (iv) obtaining signals from the sensor where a "strip chart was attached to the fluorometer and the fluorescence monitored continuously for 16 hours" (Pitner ,r 105). In addition, Pitner teaches comparing an initial reading with a later reading, and performing an algorithmic normalization, specifically teaching "[ n ]ormalized fluorescence data was generally obtained by dividing well values at selected time points by the same well' s initial reading with only media or buffer present prior to adding cells" (Pitner ,r 121). Pitner provides an output showing fluorescent data regarding the growth of E. coli in Figure 6. In sum, the evidence of record supports the Examiner's position that the claims do not add something "significantly more" to the abstract idea. Instead, the evidence shows that the additional elements in the claims are conventional, routine, and well-known. We conclude that the method claim 9 Appeal2017-007200 Application 12/918,019 does not result in an inventive concept that transforms the abstract idea described above into a patentable invention. We address Appellant's arguments below. Appellant contends that the "Examiner's conclusory application of the first step of the Mayo/Alice framework is directly at odds with the Federal Circuit's recent holdings in Enfzsh, LLC v. Microsoft Corp., 822 F.3d 1327 (Fed. Cir. 2016) andMcRo, Inc. v. Bandai Namco Games Am., [837 F.3d 1299 (Fed. Cir. 2016)]" (App. Br. 8). Appellant contends that, consistent with the facts in Enfzsh and McRo, the "claims are directed to a specific implementation of a solution to a problem in the field of culture testing (i.e., rapid, and reliable determination of the presence or absence of microorganisms in a culture)" (App. Br. 10; cf Reply Br. 2). Appellant therefore "respectfully submits that claims 1, 3-25, 27-31, 33, 38, 40-43, 46-49, and 53-55 are not even directed to an abstract idea" (App. Br. 10). We find these arguments unpersuasive because the "calculating", "determining", "computing" and "obtaining" steps are directed to an abstract mathematical approach to data analysis that is applied to the particular known test format of analytical biosensor systems, not to any improvement in the analytical biosensor itself. "'If a claim is directed essentially to a method of calculating, using a mathematical formula, even if the solution is for a specific purpose, the claimed method is nonstatutory. "' Digitech Image Technologies, LLC v. Electronics for Imaging, Inc., 758 F.3d 1344, 1351 (Fed. Cir. 2014). Similar to the claims in Electric Power Group, these steps are directed to data analysis and mathematical calculations, because they transform the data to another form without applying the resulting data further to the 10 Appeal2017-007200 Application 12/918,019 method to alter anything other than data. That is, the analysis of biosensor signals does not change anything about how the biosensor itself operates, nor is anything physical in the biosensor altered by the claimed method. Rather the instant claims focus on particular mathematical operations for analysis of the biosensor data, whether "calculating a normalization relative value" or determining "a first derivative of the normalization relative value" as in Claim 1. In either case, the focus "is on selecting certain information, analyzing it using mathematical techniques, and reporting or displaying the results of the analysis. That is all abstract." SAP America, Inc. v. Investpic, LLC, 898 F.3d 1161, 1167 (Fed. Cir. 2018). We recognize, but find unpersuasive, Appellant's reliance on the Federal Circuit decisions in Enfish and McRO. Enfish explains that "the first step in the Alice inquiry in this case asks whether the focus of the claims is on the specific asserted improvement in computer capabilities ... or, instead, on a process that qualifies as an 'abstract idea' for which computers are invoked merely as a tool." Enfish, 822 F.3d at 1335---6. Applied to claim 1, there can be no reasonable doubt that the method does not teach any improvement in computer capabilities, or indeed, any technical improvement in a biosensor apparatus, but rather "describes a data transformation that can be applied to metabolic or cell growth data" (Spec. 2:20-21). The claims in McRO were drawn to automation of the operation of a computer at a task of lip reading, where the method "uses a combined order of specific rules that renders information into a specific format that is then used and applied to create desired results: a sequence of synchronized, animated character." See McRO, 837 F.3d at 1315. Again, Appellant has not demonstrated an improvement in the operation of the computer itself, nor does Appellant create any structure such as an animated character, but 11 Appeal2017-007200 Application 12/918,019 rather Appellant simply relies on signal analysis using a particular algorithm to determine whether a culture contains a plurality of microorganism. The algorithm is an abstract idea that involves data transformation. Thus, claim 1 at best suggests an improvement where "inventive data transformation can be applied to metabolic or cell growth data in a way that provides confidence in the positive status of a vessel and essentially eliminates the potential for false negative determinations" (Spec. 31 :30-32). "[T]he focus of the claims is not a physical-realm improvement but an improvement in wholly abstract ideas-the selection and mathematical analysis of information, followed by reporting or display of the results." SAP, 898 F.3d at 1168. Appellant cites Example 2 from the 2014 Interim Guidance on Patent Subject Matter Eligibility and Example 26 from the July 2015 Update on Subject Matter Eligibility, contending that "[i]n both examples, the novel aspect of the invention was the use of a mathematical principle to improve a specific type of technology" (App. Br. 11-12; cf Reply Br. 6). Appellant contends "claim 1 explicitly provides the types of feedback that laboratory staff in a clinical laboratory can receive" (App. Br. 13). We find this argument unpersuasive because in both the robotic arm Example 2 and the internal combustion engine Example 26, the mathematical principle impacts the device itself, as in Diehr, and does more than analyze and output data. In the claim in Example 2, the device "uses the movement information from the sensor to adjust the velocity of the end effector in order to achieve a smooth motion along the predetermined motion path" (App. Br. 10, citing Example 2 from the 2014 Interim Guidance on Patent Subject Matter Eligibility). Similarly, in the claim in Example 26, the 12 Appeal2017-007200 Application 12/918,019 device functions to "calculate a position of the exhaust gas recirculation valve based upon the rate of change of the engine throttle position and change the position of the exhaust gas recirculation valve to the calculated position" (App. Br. 11, citing Example 26 from the July 2015 Update on Subject Matter Eligibility). In both of these situations, the calculations directly impact the physical operation of the device. Just as the mathematical method in Diehr improved the rubber press itself, so too, the calculations in these examples improve the physical operation of the robotic arm or combustion engine devices themselves. That is unlike the current claim 1, where the calculations result in "outputting the first result" or "displaying the first result." There is no step in the current claim 1 where the calculation impacts the incubation process for the microorganism or the way the sensors obtain signals. "Here, the focus of the claims is not any improved computer or [device], but the improved mathematical analysis; and indeed, the specification makes clear that off-the-shelf ... technology is usable to carry out the analysis." SAP, 898 F.3d at 1168. Appellant contends the "invention as claimed provides functional and palpable applications in the field of culture testing" (App. Br. 17). Appellant further contends the present claims utilize generic mathematical concepts ( e.g., normalization relative values, rate transformation values, and average relative transformation values) in a very specific and novel way to determine whether a culture in a vessel contains a plurality of microorganisms. Thus, Applicant's claims utilize generic mathematical concepts (i.e., field #1) to provide an improvement in the field of culture testing (i.e., field #2). (App. Br. 17; cf Reply Br. 5). 13 Appeal2017-007200 Application 12/918,019 We do not dispute that the use of mathematical operations, acknowledged by Appellant as "generic" in this case, may be "a positive and valuable contribution to science. But even such valuable contributions can fall short of statutory patentable subject matter, as it does here." Ariosa Diagnostics, Inc. v. Sequenom, Inc., 788 F.3d 1371, 1380 (Fed. Cir. 2015). We note that even the limitation to a particular field such as culture testing information does not rescue the claim from being abstract because "limitation of the claims to a particular field of information ... does not move the claims out of the realm of abstract ideas." SAP, 898 F .3d at 1169. Appellant contends the "claims describe in significant detail how various mathematical concepts ( e.g., normalization relative values, rate transformation values, and average relative transformation values) can be used in combination with a vessel with a culture and a sensor to determine whether the culture contains a plurality of microorganisms" (App. Br. 18). Appellant further contends that "[b ]y focusing on the individual structural elements of Applicant's claims and ignoring how the structural elements work together, Examiner has failed to appreciate that the claims as a whole do amount to significantly more than the judicial exception" (App. Br. 20; cf Reply Br. 7-8). We find these arguments unpersuasive because the asserted "unconventional steps" are solely drawn to mathematical computations that Appellant earlier in the Appeal Brief state "utilize generic mathematical concepts" (App. Br. 17). As discussed in our analysis above, particularly citing Pitner and the Specification, the evidence demonstrates that each of the manipulative steps of the method were known and used in the prior art, and 14 Appeal2017-007200 Application 12/918,019 Appellant provides no evidence or persuasive argument that any of these manipulative steps were unconventional and not used by others. To the extent that Appellant contends that the claimed invention is patentable based on an ordered combination of limitations, this type of ordered combination has been found to be patent ineligible by SAP, where comparisons of received data according to rules and the generation of outputted data was held to be abstract. Smartgene similarly involves claims to an ordered combination that involves performing data analysis and outputting a result that was held abstract. SmartGene, Inc. v. Advanced Biological Labs., SA, 555 Fed. Appx. 950, 952 (Fed.Cir. 2014). Appellant provides no persuasive evidence or reasoning explaining why the combination of "generic mathematical concepts" (App. Br. 17) with widely known biosensors as disclosed in the Specification and Pitner represents something significantly more than the judicial exception. Appellant contends that the instant claims are similar to those in SiRF Technology, Inc. v. ITC, 601 F.3d 1319 (Fed Cir. 2010), where our reviewing court found the claims to present patentable subject matter (See Appeal Br. 21- 23). Appellant specifically contends that "like the GPS receiver discussed in SiRF, Applicant's claims require the use of particular components" and "[t]herefore, the claimed sensor, like the GPS receiver in SiRF, places a meaningful limit on the scope of Applicant's claims" (App. Br. 22). We find Appellant's reliance on SiRF unpersuasive because SiRF was decided before Mayo and Alice and thus did not have the guidance provided by those cases. It is therefore not clear that SiRF was decided under the proper test. See SiRF, 601 F.3d at 1332. Nonetheless, in SiRF, the GPS receiver was considered to place a meaningful limitation on the claim because "without a GPS receiver it would be impossible to generate pseudoranges or to determine the position of the GPS receiver whose 15 Appeal2017-007200 Application 12/918,019 position is the precise goal of the claims." Id. The algorithm in SiRF was used to determine the position of the GPS receiver. The claims in this case are distinguishable because the algorithm, while receiving data from a device, namely the sensor measuring the culture, has no application to the operation of either the sensor or the culture vessel. Rather, the algorithm is used to deduce information about microorganism growth and simply outputs the data, whether as a printout or screen display. We therefore conclude that all of the claims on appeal are directed to patent-ineligible subject matter. SUMMARY In summary, we affirm the rejection of claim 1 under 35 U.S.C. § 101 as being directed to non-statutory subject matter. Pursuant to 37 C.F.R. § 4I.37(c)(l), we also affirm the rejection of claims 3-25, 27-31, 33, 38, 40-43, 46-49, and 53-55 as being directed to non-statutory subject matter as these claims were not argued separately. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). AFFIRMED 16 Copy with citationCopy as parenthetical citation
