HORNIBROOK, TING Y. LEUNG, XIN WU, DANIEL C. ZILIO, and CALISTO P. ZUZARTE Appeal2015-001419 Application 13/361,800 Technology Center 2100 Before ST. JOHN COURTENAY III, JAMES R. HUGHES, and MELISSA A. RAAP ALA, Administrative Patent Judges. COURTENAY, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE This is an appeal under 35 U.S.C. § 134(a) from the Examiner's Final Rejection of claims 8-27. Claims 1-7 are cancelled. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Invention The disclosed and claimed invention on appeal relates to techniques "for generating statistical views in a database system." Spec. i-f 11. Appeal2015-001419 Application 13/361,800 Representative Claim 8. A computer program product of statistical view refinement based on constraints in order to reduce a processing cost incurred in maintaining statistical views in a database management system, the computer program product compnsmg: a computer-readable memory including hardware and having computer-readable program code embodied therewith, the computer-readable program code executable by one or more computer processors to: responsive to receiving a request to execute a database workload, evaluating the database workload in order to generate a join graph; identify one or more constraints pertaining to executing the database workload; [L 1] evaluate the join graph in order to generate a plurality of statistical view candidates; and [L2] programmatically refine the statistical view candidates by operation of one or more computer processors when executing the computer-readable program code and based on the identified one or more constraints in order to generate a set of refined statistical view candidates, wherein statistical view generation from the plurality of statistical view candidates is restricted to the set of refined statistical view candidates. (Contested limitations LI and L2 are emphasized.) Rejection Claims 8-27 are rejected under 35 U.S.C. § 103(a) as being obvious over the combined teachings and suggestions of El-Helw et al. (US 7,668,804 Bl, Feb. 23, 2010) ("El-Helw"), in view ofKandil et al. (US 2007 /0220058 Al, Sept. 12, 2007) ("Kandil"). 2 Appeal2015-001419 Application 13/361,800 Grouping of Claims We decide the appeal of independent claims 8 and 15 on the basis of representative claim 8. To the extent Appellants have not advanced separate, substantive arguments for the remaining claims on appeal, such arguments are considered waived. See 37 C.F.R. § 41.37(c)(l)(iv). ANALYSIS We have considered all of Appellants' arguments and any evidence presented. We find Appellants' arguments unpersuasive for the reasons discussed infra. We adopt as our own: (1) the findings and legal conclusions set forth by the Examiner in the action from which this appeal is taken, and (2) the findings, legal conclusions, and explanations set forth in the Answer in response to Appellants' arguments (Ans. 4--30). We highlight and address specific findings and arguments for emphasis in our analysis below. Rejection of Independent Claim 8 under 35 U.S.C. § 103(a) Issue: Under 35 U.S.C. § 103(a), did the Examiner err in finding the cited combination of El-Helw and Kandil would have taught or suggested contested limitations LI and L2, within the meaning of independent claim 8, under a broad but reasonable interpretation? 1 1 We give the contested claim limitations the broadest reasonable interpretation consistent with the Specification. See In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997); Cf with Spec. i-f 71 ("While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow."). 3 Appeal2015-001419 Application 13/361,800 Regarding independent claim 8, Appellants contend: Respectfully, El-Helw does not disclose at least the following limitations recited in independent claim 8: [L 1] [ e ]valuate the join graph in order to generate a plurality of statistical view candidates; and [L2] programmatically refine the statistical view candidates ... based on the identified one or more constraints in order to generate a set of refined statistical view candidates, wherein statistical view generation from the plurality of statistical view candidates is restricted to the set of refined statistical view candidates. App. Br. 15. Id. In support, Appellants contend: The portions of El-Helw cited by the Office generally discuss choosing a subset of candidate statistical views that maximizes a cost/benefit ratio, see, e.g., El-Helw, col. 12, lines 23-28. At the same time, even assuming, arguendo, that the candidate statistical views in El-Helw correspond to the recited statistical view candidates, El-Helw is still silent on any join graph being evaluated in order to generate the candidate statistical views to which statistical view generation from the statistical view candidates is restricted. Further, Kandi! does not cure these deficiencies of El-Helw. Therefore, El-Helw, even in view of Kandi!, does not teach or suggest at least the underlined limitations above. Limitation LI of Independent Claim 8 Regarding Appellants' contention that "El-Helw is still silent on any join graph being evaluated in order to generate the candidate statistical views to which statistical view generation from the statistical view candidates is restricted," we find unpersuasive Appellants' assertion that "Kandi! does not cure these deficiencies of El-Helw." App. Br. 15. 4 Appeal2015-001419 Application 13/361,800 We note the Examiner (Final Act. 3) finds El-Helw (cols. 6-7) teaches the use (i.e., evaluation) of joins regarding database queries for the purpose of "generat[ing] a plurality of statistical view candidates," as claimed (claim 8, contested limitation LI). El-Helw describes, in pertinent part: In one embodiment, query optimizer 308 can be a bottom-up optimizer that generates plans that transform an n-way join into a sequence of two-way joins using binary join operators .... The candidate statistical view set will contain the corresponding definitions for each of the partial queries that contain the relevancy, local, and join predicates appropriate for the partial queries. El-Helw, col. 6, 1. 59-col. 7, 1. 2 (emphasis added). Although Appellants recite the claim language (App. Br. 15), Appellants do not substantively argue that El-Helw does not teach a join graph.2 The Examiner (Ans. 4) considers the description in Appellants' Specification (i-f 49), 3 and adopts a claim construction for the claim 8 term "join graph": A "join graph is nothing more than identifying joins in a workload which is a query statement." (Ans. 4). Appellants have not rebutted the Examiner's claim interpretation. Therefore, on this record, we 2 See In re Lovin, 652 F.3d 1349, 1357 (Fed. Cir. 2011) ("[W]e hold that the Board reasonably interpreted Rule 41.37 to require more substantive arguments in an appeal brief than a mere recitation of the claim elements and a naked assertion that the corresponding elements were not found in the prior art."). 3 See Spec. i-f49 ("At step 320, the statistical view advisor 152 generates a join graph based on the received workload. The join graph is subsequently used in identifying which joins are used in conjunction with one another, to form one or more statistical views."). 5 Appeal2015-001419 Application 13/361,800 are not persuaded the Examiner's reading is overly broad, unreasonable, or inconsistent with Appellants' Specification. 4 We note El-Helw describes joins (col. 10, 1. 59) in the context of graph structure 460 (see El-Helw, col. 10, 1. 67- col. 11, 1. 1 ("e.g., a sample graph structure is shown as graph 460 of FIG. 4C")). See also, El-Helw, col. 11, 11. 7-9: "Each group Vo can contain the views that involve the same set of tables and have the same join predicates between these tables." (Emphasis added). Because we find join operations of relational database tables are notoriously well known in the art (as evidenced by El-Helw, e.g., col. 1, 11. 24--25 5), and because Appellants fail to substantively address the Examiner's specific findings (Ans. 4--6), on this record, we are not persuaded the Examiner erred regarding contested limitation L 1. Limitation L2 of Independent Claim 8 The Examiner finds El-Helw (col. 12, 11. 23-35) teaches or suggests contested limitation L2 of claim 8: programmatically refine the statistical view candidates ... based on the identified one or more constraints in order to generate a set of refined statistical view candidates, wherein statistical view generation from the plurality of statistical view candidates is restricted to the set of refined statistical view candidates. 4 Because "applicants may amend claims to narrow their scope, a broad construction during prosecution creates no unfairness to the applicant or patentee." In re ICON Health and Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) (citation omitted). 5 See El-Helw, e.g., col. 1, 11. 24--25 ("The performance of a query plan is determined largely by the order in which the tables are joined."). 6 Appeal2015-001419 Application 13/361,800 Final Act. 4. Appellants fail to substantively address these findings, and merely assert that El-Helw does not teach the recited limitation. See App. Br. 15. Because Appellants fail to address the Examiner's specific findings, on this record, we are not persuaded the Examiner erred regarding contested limitation L2. Comb inability under § 103 Appellants additionally contend the Examiner has improperly combined El-Helw and Kandil: "the Office merely posits that El-Helw can be modified using Kandi!, on the basis of generally desirable features - such as increasing usability- and without any specific explanation of how the proposed combination of El-Helw and Kandi! would synergistically interoperate to produce the claimed embodiment." App. Br. 16. However, the Supreme Court guides: "[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill." KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Moreover, "[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results." Id. at 416. "If a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability." Id. at 417. This reasoning is applicable here. On this record, we find the Examiner provides sufficient articulated reasoning with some rational underpinning to support the legal conclusion of obviousness (Final Act. 4). Moreover, we find El-Helw and Kandil are analogous art to each other, and to the claimed invention. See, e.g., El-Helw, Abstract: 7 Appeal2015-001419 Application 13/361,800 A workload to be handled by a database system can be identified. The workload can include at least one query that the database system is to handle. A set of at least one candidate statistical views ( statviews) to be utilized when optimizing the workload can be enumerated. A benefit value and a cost value of the each of the enumerated candidate statistical views relative to the entire workload can be computed. See, e.g., Kandil, Abstract: A method, computer program product, and system for managing statistical views in a database system are provided. The method, computer program product, and system provide for collecting data relating to optimization and execution of a workload in the database system and automatically generating a set of one or more statistical views based on the collected optimization and execution data. Appellants do not point to any evidence of record that shows combining the references in the manner proffered by the Examiner would have been "uniquely challenging or difficult for one of ordinary skill in the art" or would have "represented an unobvious step over the prior art." Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (citing KSR, 550 U.S. at 418). Nor have Appellants provided objective evidence of secondary considerations which our reviewing court guides "operates as a beneficial check on hindsight." Cheese Systems, Inc. v. Tetra Pak Cheese and Powder Systems, Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013). Therefore, we find unavailing Appellants' contention "the proposed modification of El-Helw using Kandil is merely conclusory." App. Br. 16. On this record, and based upon a preponderance of the evidence, we are not persuaded of error regarding the Examiner's ultimate legal conclusion of obviousness regarding contested limitations L 1 and L2 of 8 Appeal2015-001419 Application 13/361,800 representative claim 8. Accordingly, we sustain the Examiner's rejection of representative claim 8, and the rejection of grouped independent claim 15 (not separately argued), which falls with claim 8 (see Grouping of Claims, supra). Dependent Claims 9-14 and 16--2 7 Regarding the remaining dependent claims, for which Appellants purport to advance separate arguments, we find the Examiner provides sufficiently detailed mappings of the claim terms to the corresponding features found in the cited El-Helw and Kandil references to support the prima facie case of obviousness. The Federal Circuit guides, "the prima facie case is merely a procedural device that enables an appropriate shift of the burden of production." Hyatt v. Dudas, 492 F.3d 1365, 1369 (Fed. Cir. 2007). [A ]ll that is required of the office to meet its prima facie burden of production is to set forth the statutory basis of the rejection and the reference or references relied upon in a sufficiently articulate and informative manner as to meet the notice requirement of [35 U.S.C.] § 132. As the statute itself instructs, the examiner must "notify the applicant," "stating the reasons for such rejection," "together with such infonnation and references as may be useful in judging the propriety of continuing prosecution of his application." In re Jung, 637 F.3d 1356, 1363 (Fed. Cir. 2011). Here, the Examiner's burden of establishing a prima facie case is met by "adequately explain[ing] the shortcomings [the USPTO] perceives so that the applicant is properly notified and able to respond." Hyatt, 492 F.3d at 1370. In reviewing the record, we find the Examiner has met the notice requirement of 35 U.S.C. § 132 by providing a detailed statement of rejection with sufficiently clear mappings and explanations. Final Act. 5- 9 Appeal2015-001419 Application 13/361,800 17. We note it is only "when a rejection is so uninformative that it prevents the applicant from recognizing and seeking to counter the grounds for rejection" that the prima facie burden has not been met and the rejection violates the minimal requirements of 35 U.S.C. § 132. Chester v. Miller, 906 F.2d 1574, 1578 (Fed. Cir. 1990). Such is not the case here. By making specific factual findings regarding the dependent claims, and satisfying the notice requirement of 35 U.S.C. § 132 to establish the prima facie case, the Examiner shifted the burden of production to Appellants to go forward with evidence showing why such factual findings are erroneous-a burden we find Appellants have failed to meet. In traversing the Examiner's rejection of the remaining dependent claims, we observe Appellants adopt a pattern of argument in the Brief which: (1) reproduces the portions ofEl-Helw and/or Kandil cited by the Examiner, (2) merely asserts the cited portions of the references are "silent" regarding the contested claim limitations, and (3) fails to substantively respond to the specific findings set forth by the Examiner (Final Act. 5-17) for each contested dependent claim. In the Answer (6---30), the Examiner provides a detailed responsive explanation to Appellants' nominal arguments regarding the contested dependent claims. Appellants have not further responded to these explanations, because no Reply Brief was filed. Because Appellants fail to provide any persuasive evidentiary basis to support their assertions regarding the remaining dependent claims, we find Appellants' arguments are merely conclusory, and do not meet the burden of showing error in the Examiner's prima facie case of obviousness. App. Br. 10 Appeal2015-001419 Application 13/361,800 17--42. To the extent Appellants reproduce the record by copying the portions of the references cited by the Examiner into the Brief, and then merely assert the cited portions are "silent" regarding the claim language, we find Appellants fail to advance separate substantive, persuasive arguments explaining why the Examiner has erred. Mere conclusory statements that are unsupported by factual evidence are entitled to little probative value. In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997); In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984). Therefore, on this record, we find Appellants have failed to substantively traverse the merits of the rejection of the contested dependent claims, by specifically explaining why the Examiner erred. Under our PT AB procedural rule: "A statement which merely points out what a claim recites will not be considered an argument for separate patentability of the claim." 37 C.F.R. § 41.37(c)(l)(iv). If an Appellant fails to present arguments on a particular issue----or, more broadly, on a particular rejection-the Board will not, as a general matter, unilaterally review those uncontested aspects of the rejection. Ex parte Frye, 94 USPQ2d 1072, 107 5 (BP AI 2010) (precedential) (citing, inter alia, Hyatt v. Dudas, 551F.3d1307, 1313-14 (Fed. Cir. 2008) (the Board may treat arguments Appellant failed to make for a given ground of rejection as waived)). Therefore, after considering the totality of the record, including the evidence relied upon by the Examiner, with due consideration to the insufficiency of the arguments presented, we find Appellants have not shown error in the Examiner's prima facie case of obviousness. On this record, we find a preponderance of the evidence supports the Examiner's 11 Appeal2015-001419 Application 13/361,800 underlying factual findings and ultimate legal conclusion of obviousness for all contested claims on appeal. Accordingly, we sustain the Examiner's rejection of claims 8-27 under§ 103(a). DECISION We affirm the Examiner's rejection of claims 8-27 under 35 U.S.C. § 103(a). No time for taking any action connected with this appeal may be extended under 37 C.F.R. § 1.136(a)(l). See 37 C.F.R. § 41.50(±). AFFIRMED 12 Copy with citationCopy as parenthetical citation
