MacDONALD, AMBER L. HAGY, and MICHAEL M. BARRY, Administrative Patent Judges. HAGY, Administrative Patent Judge. DECISION ON APPEAL Appellants1 appeal under 35 U.S.C. § 134(a) from the Examiner’s Final Rejection of claims 1, 2, 4—12, and 15—22, which are all of the pending claims.2 We have jurisdiction over these claims under 35 U.S.C. § 6(b). We affirm. 1 Appellants identify Intel Corp. as the real party in interest. (App. Br. 2.) 2 Claims 3, 13, 14, 23, and 24 have been canceled in an Amendment filed February 21, 2014. Appeal 2017-002844 Application 13/621,994 STATEMENT OF THE CASE Introduction According to Appellants, “[t]he inventions generally relate to a modular and scalable PCI-Express implementation.” (Spec. 13.) Exemplary Claim Claim 1, reproduced below with the disputed limitation italicized, is exemplary of the claimed subject matter: 1. An apparatus comprising: a functional PCI Express port including first buffers; an idle PCI Express port including second buffers; and a common data bus that communicatively couples the functional PCI Express port to the idle PCI Express port, wherein one or more of the second buffers of the idle PCI Express port are accessed by the functional PCI Express port through the common data bus. References The prior art relied upon by the Examiner in rejecting the claims on appeal is: Manula et al. (“Manula”) US 7,424,566 B2 Sept. 9, 2008 Accapadi et al. (“Accapadi”) US 2008/0244118 Al Oct. 2, 2008 Alfieri et al. (“Alfieri”) US 7,630,389 B1 Dec. 8, 2009 Rejections Claims 5 and 7 stand rejected under 35U.S.C. § 112, second paragraph, as being indefinite. (Final Act. 2.) 2 Appeal 2017-002844 Application 13/621,994 Claims 1, 2, 4—7, 10-12, 15—17, and 20-22 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Manula and Accapadi. (Final Act. 2-8.) Claims 8, 9, 18, and 19 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Manula, Accapadi, and Alfieri. (Final Act. 8.) ISSUES (1) Whether the Examiner erred in finding the combination of Manula and Accapadi teaches or suggests “a common data bus that communicatively couples the functional PCI Express port to the idle PCI Express port, wherein one or more of the second buffers of the idle PCI Express port are accessed by the functional PCI Express port through the common data bus,” as recited in independent claim 1 and commensurately recited in independent claim 15. (2) Whether the Examiner erred in finding the combination of Manula, Accapadi, and Alfieri teaches or suggests “wherein the clock gating device is to provide power to the second buffers,” as recited in dependent claim 9 and commensurately recited in dependent claim 19. ANALYSIS We have reviewed the Examiner’s rejections in light of Appellants’ arguments the Examiner has erred. We disagree with Appellants’ conclusions and we adopt as our own: (1) the findings and reasons set forth by the Examiner in the action from which this appeal is taken (Final Act. 2— 9); and (2) the reasons set forth by the Examiner in the Examiner’s Answer in response to Appellants’ Appeal Brief (Ans. 5—14). We concur with the 3 Appeal 2017-002844 Application 13/621,994 conclusions reached by the Examiner, and we highlight the following for emphasis.3 A. Indefiniteness Rejection of Claims 5 and 7 Appellants do not argue on appeal the Examiner’s rejection of claims 5 and 7 as indefinite under 35 U.S.C. § 112, second paragraph. In particular the Examiner rejects these claims for “insufficient antecedent basis” because each claim recites “[t]he apparatus of claim 3,” but claim 3 has been canceled. (Final Act. 2.) Appellants state only “Applicants are willing to amend claims 5 and 7 pending the outcome of the present appeal.” (App. Br. 4.) Meanwhile, however, because this rejection has not been withdrawn by the Examiner (Ans. 5—6) and has not been addressed substantively on appeal, we summarily sustain this rejection. See 37 C.F.R. § 41.37(c)(l)(iv) and Manual of Patent Examining Procedure (MPEP) § 1205.02, 9th ed., March 2014 (“If a ground of rejection stated by the examiner is not addressed in the appellant’s brief, appellant has waived any challenge to that ground of rejection and the Board may summarily sustain it, unless the examiner subsequently withdrew the rejection in the examiner’s answer.”). 3 Only those arguments made by Appellants have been considered in this decision. Arguments Appellants did not make have not been considered and are deemed to be waived. See 37 C.F.R. § 41.37(c)(l)(iv). 4 Appeal 2017-002844 Application 13/621,994 B. Claims 1, 2, 4—8, 10—12, 15—18 and 20—22 The Examiner finds Manula teaches the limitations of claim 1, except “where buffers of the idle port are accessed by the functional port.” (Final Act. 3.) As to that limitation, the Examiner finds Accapadi teaches a system in which components are “allocated buffers from memory,” such that “[w]hen a particular component (port) is idle (Fig. 3, 302, donor components) and its buffers (Fig. 3, 310) are therefore free, they can be used by another component (requestor component) which needs more buffers (Fig. 3, 318; par. 45).” (Final Act. 4.) The Examiner further finds, “[i]n this way, buffer allocation is made more efficient and the system performance is better managed (par. 8; par. 93).” (Id.) Appellants’ arguments are premised on piecemeal challenges to the Examiner’s reliance on each of the cited references. In particular, although Appellants concede “Manula describes a PCIe port that includes buffers,” the Examiner’s findings are in error because “Manula says nothing about enabling a functional port to access the buffers included in an idle port.” (App. Br. 6.) Appellants also acknowledge “[t]he Examiner relies on Accapadi to provide the missing subject matter,” but argue the Examiner’s findings are in error because “Accapadi says nothing about a buffer included in a port.'” (App. Br. 7.) We are not persuaded of error. The test for obviousness is not whether the claimed invention must be expressly suggested in any one or all of the references. “Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981) (citations omitted) (emphasis added). Thus, where, as here, the rejections are based upon the teachings of 5 Appeal 2017-002844 Application 13/621,994 a combination of references, “[n]on-obviousness cannot be established by attacking references individually.” In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (citing Keller, 642 F.2d at 425). In addition, a reference “must be read, not in isolation, but for what it fairly teaches in combination with the prior art as a whole.” Id. As noted above, the Examiner finds the subject matter of claim 1 is taught or suggested by the combined teachings of Manula and Accapadi. (Final Act. 3^4; see also Ans. 12—13.) We agree the Examiner’s findings are supported by the teachings of the cited references. We are also unpersuaded by Appellants’ conclusory statement that “the Examiner has not provided an ‘articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.’” (App. Br. 7.) To the contrary, the Examiner has provided a rationale supporting motivation by a person of ordinary skill in the art to achieve the claimed subject matter. (Final Act. 4; see also Ans. 8.) Specifically, the Examiner finds “it would have been obvious to one of ordinary skill in this art at the time of invention by Applicant to utilize the buffer allocation method as taught by Accapadi et al. in the system of Manula et al. for the purpose of dynamically allocating buffers from ports that are not using them to ports that do. This would have been obvious in order to improve system performance.” (Final Act. 4.) The Examiner premises this finding, in part, on teachings in Accapadi that reallocating buffers from idle components to active components results in “more efficient” buffer allocation “and the system performance is better managed.” {Id. (citing Accapadi Tflf 8, 93).) Appellants have not provided persuasive evidence or line of reasoning explaining why the Examiner’s rationale is erroneous or why a person of 6 Appeal 2017-002844 Application 13/621,994 ordinary skill in the art would not have reached the conclusions reached by the Examiner. See DyStar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006) (“[T]he proper question is whether the ordinary artisan possesses knowledge and skills rendering him capable of combining the prior art references.”). For the foregoing reasons, we are not persuaded of error in the Examiner’s rejection of independent claim 1, and, therefore, we sustain that rejection, along with the rejection of independent claim 15 (which is argued on the same basis of claim 1) and dependent claims 2, 4—7, 8, 10-12, 15—18 and 20—22, which are not argued separately. (App. Br. 8—9.) C. Claims 9 and 19 Claim 8 depends from claim 1, and recites the apparatus “further compris[es] a clock gating device to limit power to the idle PCI Express port.” (Claims App’x 3.)4 Claim 9 depends from claim 8, and further recites “wherein the clock gating device is to provide power to the second buffers.” (Id. ) Claims 18 and 19 depend from claim 15, and recite commensurate limitations in method form. (Claims App’x 4.) The Examiner relies on the combination of Manula, Accapadi and Alfieri as teaching or suggesting the subject matter of claims 8, 9, 18, and 19. In particular, the Examiner finds, and we agree, “Alfieri teaches a system wherein clock gating is utilized to reduce power consumption for idle components.” (Final Act. 8 (citing Alfieri col. 4:11—27).) Appellants argue the Examiner’s findings regarding claims 9 and 19 are in error because Alfieri “says nothing about applying clock gating to an 4 References herein to “Claims App’x” are to the corrected Claims Appendix filed on February 26, 2015, in which Appellants “include claims 5 and 7 as requested by the Examiner.” 7 Appeal 2017-002844 Application 13/621,994 idle port while continuing to provide power to buffers included in an idle port, as generally recited in claims 9 and 19.” (App. Br. 9—10 (emphases added).) We are not persuaded of error. Appellants’ arguments, again, improperly challenge the references piecemeal while disregarding the combined teachings of the cited references. With regard to the claimed ports and buffers, and reallocation of unused buffers, the Examiner does not purport to rely on Alfieri. but instead specifically relies on the combination of Manula and Accapadi, as noted above. (Final Act. 3—4.) The Examiner adds Alfieri as teaching use of clock gating to reduce power consumption to idle components, and relies on the combination of Alfieri, Manula, and Accapadi as teaching the subject matter of claims 8, 9, 18, and 19. {Id. at 8.) Appellants do not persuasively rebut the Examiner’s findings regarding the combined teaches of these references. In short, Appellants have not persuaded us of error in the Examiner’s rejection of claims 9 and 19, or claims 8 and 18, which are not separately argued. We, therefore, sustain the rejection of claims 8, 9, 18, and 19. DECISION For the above reasons, the Examiner’s rejections of claims 1, 2, 4—12, and 15—22 are affirmed. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). AFFIRMED 8 Copy with citationCopy as parenthetical citation
