BRANCH, Administrative Patent Judges. THOMAS, Administrative Patent Judge. DECISION ON APPEAL Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–20. We have jurisdiction over the appeal 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 International Business Machines Corporation. Appeal Br. 2. Appeal 2018-000964 Application 14/139,456 2 The present invention relates generally to automatically generating a set of test questions. See Abstr. Independent claim 1, reproduced below, is representative of the appealed claims: 1. A method, in a data processing system comprising a processor and a memory, for automatically generating a set of test questions for use in generating a test to be administered to human test takers, the method comprising: ingesting, by test question answer extraction engine logic executing on one or more processors in the data processing system, a document from a corpus of documents to select a potential test question answer from the document; generating, by test question generation engine logic executing on the one or more processors in the data processing system, a candidate test question based on the potential test question answer; evaluating, by a Question and Answer (QA) system, the candidate test question to generate a result indicative of whether the candidate test question should be maintained for test generation; storing, by the data processing system, the candidate test question in the set of test questions in response to a result indicating that the candidate test question should be maintained for test generation; and transmitting, by test generation engine logic executing on the one or more processors in the data processing system, to at least one other computing device, the set of test questions to administer the test to at least one human test taker via the at least one other computing device. Appellant appeals the following rejection: Claims 1–20 are rejected under 35 U.S.C. § 101 because the claimed invention is directed to patent-ineligible subject matter. Final Act. 2–15 We review the appealed rejections for error based upon the issues identified by Appellant, and in light of the arguments and evidence produced Appeal 2018-000964 Application 14/139,456 3 thereon. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential). ANALYSIS Rejection under § 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 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 Supreme Court’s two-step 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 the 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 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.”). For example, 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, 69 (1972)). Recently, the USPTO published revised guidance on the application of 35 U.S.C. § 101. USPTO’s 2019 Revised Patent Subject Matter Appeal 2018-000964 Application 14/139,456 4 Eligibility Guidance, 84 Fed. Reg. 50 (Jan. 7, 2019) (“Revised Guidance”). Under the Revised Guidance “Step 2A,” the office first looks 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); and (2) additional elements that integrate the judicial exception into a practical application (see MPEP § 2106.05(a)-(c), (e)-(h)). 84 Fed. Reg. at 51–52, 55. Only if a claim (1) recites a judicial exception and (2) does not integrate that exception into a practical application, does the Office then (pursuant to the Revised Guidance “Step 2B”) 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)); 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. 84 Fed. Reg. at 56. Step 2A, Prong 1 (Does the Claim Recite a Judicial Exception?) With respect to independent method claim 1, and similarly, computer readable storage medium claim 11 and apparatus claim 20, the Examiner determines that the claims are directed to “‘An Idea Of Itself,’ . . . such as collecting and comparing known information and/or obtaining and comparing intangible data, and/or comparing new and stored information and using rules to identify options” (Final Act. 3–4), which we conclude are mental processes, which is a type of abstract idea. Appeal 2018-000964 Application 14/139,456 5 Although the previously recognized category of “an idea of itself” is not one of the currently recognized categories, it is sufficient for the purposes of the present appeal that the claimed concepts reasonably can be characterized as falling within the still-recognized category of mental processes. See, e.g., MPEP § 2106.04(a)(2)(III): The courts have used the phrase ‘an idea ‘of itself’” to describe an idea standing alone such as an instantiated concept, plan or scheme, as well as a mental process (thinking) that “can be performed in the human mind, or by a human using a pen and paper.” CyberSource Corp. v. Retail Decisions, Inc., 654 F.3d 1366, 1372 (Fed. Cir. 2011). This is true even if the claim recites that a generic computer component performs the acts. See, e.g., Versata Dev. Grp., Inc. v. SAP Am., Inc., 793 F.3d 1306, 1335 (Fed. Cir. 2015) (“Courts have examined claims that required the use of a computer and still found that the underlying, patent-ineligible invention could be performed via pen and paper or in a person’s mind.”); see also 2019 Eligibility Guidance 84 Fed. Reg. at 52 n.14 (“If a claim, under its broadest reasonable interpretation, covers performance in the mind but for the recitation of generic computer components, then it is still in the mental processes category unless the claim cannot practically be performed in the mind.”). Specifically, Claim 1 recites at least the following limitations: (1) “ingesting . . . a document . . . to select a potential test question answer,” (2) “generating . . . a candidate test question,” (3) “evaluating . . . the candidate test question to generate a result,” (4) “storing . . . the candidate test question,” and (5) “transmitting . . . the set of test questions.” Claim 1. We agree with the Examiner (see Final Act. 4) that these limitations, under their broadest reasonable interpretation, encompass acts people can Appeal 2018-000964 Application 14/139,456 6 perform using their minds or pen and paper because people can perform the “ingesting . . . a document” and “generating . . . a candidate test question” steps by simply looking at a document and observing answers from the document and then use pen and paper to write down candidate test questions. People can also perform the “evaluating” step by looking at the candidate test questions and making a judgment as to whether the question should be maintained. Finally, people can “store” the test question by merely remembering the questions and/or writing them down, and “transmit” the test questions by merely passing a piece of paper to one another with the questions written thereon. As noted by the Examiner, it is common for teachers/educators to perform such acts. See id. Appellant’s Specification discloses: With the increased usage of computing networks, such as the Internet, humans are currently inundated and overwhelmed with the amount of information available to them from various structured and unstructured sources. However, information gaps abound as users try to piece together what they can find that they believe to be relevant during searches for information on various subjects. To assist with such searches, recent research has been directed to generating Question and Answer (QA) systems which may take an input question, analyze it, and return results indicative of the most probable answer to the input question. QA systems provide automated mechanisms for searching through large sets of sources of content, e.g., electronic documents, and analyze them with regard to an input question to determine an answer to the question and a confidence measure as to how accurate an answer is for answering the input question. Spec. ¶ 2. In other words, Appellant’s invention is concerned with automating searching through large sets of content for potential test question Appeal 2018-000964 Application 14/139,456 7 answers, analyzing such answers, and providing candidate test questions based thereon. We agree with the Examiner that the rejected claims “involve data collection, data comparison[,] and using rules to identify options.” Final Act. 4. However, information collection and analysis, including when limited to particular content, is within the realm of abstract ideas. See, e.g., Elec. Power Grp. LLC v. Alstom S.A., 830 F.3d 1350, 1353 (Fed. Cir. 2016) (holding that “collecting information, analyzing it, and displaying certain results of the collection and analysis” are “a familiar class of claims ‘directed to’ a patent-ineligible concept.”). See also, e.g., Content Extraction & Transmission LLC v. Wells Fargo Bank, Nat’l Ass’n, 776 F.3d 1343, 1347 (Fed. Cir. 2014) (finding claims directed to collecting data, recognizing certain data within the collected data set, and storing the recognized data drawn to an abstract idea and noting that “humans have always performed these functions”). Thus, Appellant’s claims are comparable to other claims that recite abstract ideas. Appellant challenges the Examiner’s determinations on the grounds that “[t]he FOA does not identify what this alleged abstract idea is” (Appeal Br. 5), “[t]he FOA merely presents an unsubstantiated conclusion” (id.), and “[t]he FOA fails to even map any of the features of the claims to specific elements of an alleged (and unidentified) abstract idea.” Id. Appellant also contends that they “are not claiming some unspecified abstract idea that can be performed by a human being using pen and paper as alleged by the FOA” (id. at 6), and “the FOA is not examining that actual claimed invention, but rather an oversimplification and generalization.” Id. at 7. Appeal 2018-000964 Application 14/139,456 8 Contrary to Appellant’s contentions, the Examiner clearly noted the claims as being similar to concepts such as “collecting and comparing known information” and that “[i]t is common practice, using pen and paper, . . . [to] generate test question(s).” Final Act. 3–4. As demonstrated supra, such a characterization falls squarely under our “mental processes” category of abstract concepts. Furthermore, it is plainly evident that the Examiner considered all the limitations in the claim and the Examiner’s analysis is indeed tethered to actual claim language (see Final Act. 3–4). We determine the Examiner properly and reasonably found that claim 1 recites steps that can be performed by “using pen and paper” (id. at 4) and that that is an abstract idea, i.e., mental processes. The Examiner simply condensed the abstract concept. Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1240–41 (Fed. Cir. 2016) (“An abstract idea can generally be described at different levels of abstraction. As the Board has done, the claimed abstract idea could be described as generating menus on a computer, or generating a second menu from a first menu and sending the second menu to another location. It could be described in other ways, including, as indicated in the specification, taking orders from restaurant customers on a computer.”) Whichever way the concept is described, we do not see that Appellant has adequately shown that claim 1 does not recite an abstract idea. Just because the claim includes more words than the phrase the Examiner uses as an articulation of the abstract idea is an insufficient reason to persuasively argue that claim 1 does not recite an abstract idea. Further, the identified abstract idea need not encompass every claim limitation. Otherwise, there would be no need for step two of the Alice inquiry. Alice, 573 U.S. at 218. Appeal 2018-000964 Application 14/139,456 9 Therefore, for at least the aforementioned reasons, we agree with the Examiner that claim 1 recites an abstract idea, which we conclude is a “mental processes.” Step 2A—Prong 2 (integration into Practical Application) 2 Under the Revised Guidance, we now must determine if additional elements in the claims integrate the judicial exception into a practical application (see MPEP § 2106.05(a)–(c), (e)–(h)). Here, we have discern additional combination of elements recited in Appellant’s representative claim 1 that integrates the judicial exception into a practical application. See Revised Guidance, 84 Fed. Reg. at 54–55 (“Prong 2”). For example, Appellant’s claimed additional elements (e.g., “data processing system,” “processor,” “memory,” “test question answer extraction logic,” “test question generation engine logic,” and the “Question and Answer (QA) system”) do (1) improve the functioning of a computer or other technology and (2) are applied with a particular machine (beyond a generic computer). See MPEP § 2106.05(a)–(c), (e)–(h). Specifically, Appellant contends, and we agree, that “the claimed invention not only provides a computer system based mechanism for generating test questions . . . but then also provides a computer system based mechanism for evaluating the generated test questions” (Appeal Br. 10), “which includes a Question and Answer (QA) system, for evaluating those generated test questions.” Id. 2 We acknowledge that some of the considerations at Step 2A, Prong 2, properly may be evaluated under Step 2 of Alice (Step 2B of the Office revised guidance). For purposes of maintaining consistent treatment within the Office, we evaluate them under Step 1 of Alice (Step 2A of the Office revised guidance). See Revised Guidance, 84 Fed. Reg. at 55 n.25, 27–32. Appeal 2018-000964 Application 14/139,456 10 Appellant’s Specification discloses: The illustrative embodiments provide mechanisms for dynamically generating and validating test questions from a corpus using a natural language processing system, such as a Question and Answer (QA) system. The illustrative embodiments not only generate the test questions that are candidates to test the knowledge and/or abilities of students with regard to the subject matter covered by a corpus of documents, but also provides mechanisms for evaluating these generated questions to thereby eliminate badly formed questions that should not be presented to the student or are unlikely to result in a student providing a correct answer to the posed test question. A QA system may be augmented to be an evaluator for synthetically generated questions generated using the mechanisms of the illustrative embodiments. Spec. ¶ 15. In other words, Appellant’s Specification describes specific logic executed by the QA system to evaluate whether candidate test questions are suitable for test takers and should be maintained, i.e. eliminate badly formed questions. Appellant’s Specification also describes problems arising in the context of static automated mechanisms for generating tests, whereby such systems are limited to existing sets of questions. Spec. ¶ 17. The Specification further discusses the need to provide dynamic identification and validation of test questions from a corpus. Spec. ¶ 1. Specifically, Appellant’s Specification states: Current automated mechanisms for generating tests/quizzes are limited to selecting questions from an already existing set of test questions that were generated manually and placed in a database. That is, a set of questions may be provided along with the instructional material and the automated aspect of test/quiz generation is limited to simply selecting a subset of questions from the already provided set of questions. This requires much effort and expense on the part of Appeal 2018-000964 Application 14/139,456 11 the provider of the instructional material to generate the set of questions prior to distributing the instructional material and question set. Furthermore, such automated mechanisms are static and limited to the original set of questions provided. There is no ability to dynamically generate new questions to be added to the set of questions, or dynamically generate a completely new set of questions, based on the instructional material or changes to the instructional material. Spec. ¶ 17. The QA system 440 operates in the manner previous described above but with regard to the candidate test questions and variants generated by the test question generation engine 430. In so doing, some automatically generated candidate test questions/variants may be poorly worded or malformed by the automated mechanisms. As a result, the QA system 440 may not be able to satisfactorily parse and analyze the candidate test question/variant. For example, if the question is ungrammatical, the parsing stage of the QA system 440 will fail. However, if the question is grammatical, but the question is phrased in such a way that the QA system is unable to clearly identify a focus of the question, a lexical answer type of the question, or any other important characteristics of the question needed to generate candidate answers, then the question may fail during the parsing stage of the QA system 440. For example, the question “How is Darwin’s study about evolution?” is a grammatical question with poor phrasing that does not indicate the question’s focus. Such poorly worded or malformed questions may be immediately discarded from further consideration by the QA system 440 and will result in the QA system 440 not performing its further operations for generating candidate answers for the input question. Id. ¶ 74. We determine that the computer-related limitations in claim 1 capture the improvement discussed in the Specification, and are thereby sufficient to integrate the judicial exception into a practical application. In particular, the Appeal 2018-000964 Application 14/139,456 12 Question and Answer (QA) system evaluating the candidate test question, to generate a result indicative of whether the candidate test question should be maintained for test generation, integrates the judicial exception into a practical application. As such, we agree with Appellant that “the present claims recite an improvement to computer-related technology by improving the functionality of computer-related technology with regard to the automatic generation of a set of test questions for use in generating a test to be administered to human test takers.” Appeal Br. 15, citing Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1335–36 (Fed. Cir. 2016) and McRO, Inc. v. Bandai Namco Games Am. Inc., 837 F.3d 1299, 1313–14 (Fed. Cir. 2016), see also MPEP § 2106.05(a); 84 Fed. Reg. 55. For at least the reason noted supra, we determine that although claim 1 recites a judicial exception, the additional combination of elements integrate that exception into a practical application. Thus, representative claim 1 is not directed to an abstract idea. Therefore, the Examiner’s rejection of claims 1–20 under 35 U.S.C. § 101 is reversed. CONCLUSION In summary: Claims Rejected 35 U.S.C. § Reference(s)/Basis Affirmed Reversed 1–20 101 Eligibility 1–20 REVERSED Copy with citationCopy as parenthetical citation
