ENGELS, SCOTT B. HOWARD, and JOHN D. HAMANN, Administrative Patent Judges. HAMANN, Administrative Patent Judge. DECISION ON APPEAL Appellants file this appeal under 35 U.S.C. § 134(a) from the Examiner’s Final Rejection of claims 1—21. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 According to Appellants, the real party in interest is International Business Machines Corporation. App. Br. 4. Appeal 2016-005431 Application 13/413,590 THE CLAIMED INVENTION Appellants’ claimed invention relates to “network intermediaries providing dynamic proxying between client applications and service providers.” Spec. 11. Claim 1 is illustrative of subject matter on appeal and is reproduced below. 1. A method to manage subscriptions over a network, the network comprising a plurality of network intermediaries, clients, and service providers, the method comprising: at a network intermediary, receiving a subscription, the subscription having management application data, the subscription having application level header information; at the network intermediary, reviewing the application level header information of the received subscription; at the network intermediary, redirecting the subscription over the network using the reviewed application level header information; at the network intermediary, managing a proxy for a client management application subscription such that the client management application is not aware of change in its subscription; at the network intermediary, accepting protocol messages from a peer network intermediary; and at the network intermediary, proxying a subscription on behalf of the client management application. REJECTIONS2 ON APPEAL (1) The Examiner rejected claims 1—5, 7—9, 11—14, 16, and 19-21 under 35 U.S.C. § 103(a) as being unpatentable over the combination of 2 The Examiner also provisionally rejected claims 1—20 for obviousness-type double patenting over claims 1—20 of copending Application No. 12/705,954. No patent has issued yet from that copending Application, nor do Appellants present arguments traversing this provisional rejection. We find it is premature to address this provisional rejection. See In re Moncla, 95 USPQ2d 1884, 1885 (BPAI 2010) (precedential). 2 Appeal 2016-005431 Application 13/413,590 Dahlen (US 2009/0125628 Al; published May 14, 2009), Hunt (US 2005/0108251 Al; published May 19, 2005), and Alspector (US 8,214,437 Bl; issued July 3, 2012). (2) The Examiner rejected claims 6, 10, 17, and 18 under 35 U.S.C. § 103(a) as being unpatentable over the combination of Dahlen, Hunt, Alspector, and Chen (US 2004/0001498 Al; published Jan. 1, 2004). (3) The Examiner rejected claim 15 under 35 U.S.C. § 103(a) as being unpatentable over the combination of Dahlen, Hunt, Alspector, and Kryskow (US 2003/0055670 Al; published Mar. 20, 2003). ANALYSIS We have reviewed the Examiner’s rejections in light of Appellants’ contentions that the Examiner erred. In reaching our decision, we consider ah evidence presented and all arguments made by Appellants. We disagree with Appellants’ arguments and we incorporate herein and adopt as our own the findings, conclusions, and reasons set forth by the Examiner in (1) the January 30, 2015 Final Office Action (“Final Act.” 2—17), (2) the April 22, 2015 Advisory Action (“Adv. Act.” 2), and (3) the March 9, 2016 Examiner’s Answer (“Ans.” 2—25). We highlight and address, however, specific findings and arguments below for emphasis. (1) Changing Dahlen’s principle of operation Appellants argue that combining Dahlen with the other cited references impermissibility changes Dahlen’s principle of operation because (0 Dahlen teaches SIP for the communications protocol rather than SOAP (App. Br. 9—13 § 4.2); (ii) Dahlen teaches that the intermediaries look inwardly (i.e., use the SOAP Action headers), rather than querying peer 3 Appeal 2016-005431 Application 13/413,590 intermediaries in accordance with the claims (App. Br. 9—13 § 4.2 (managing proxying) and 20—21 § 4.7 (identifying peers having access to certain data flows)); and (iii) adding a timeout is contrary to the purpose of real-time SIP communication sessions (App. Br. 32—33 § 4.13). (i) Replacing SIP with SOAP Appellants argue that the Examiner incorrectly changes Dahlen’s teachings from session initiation protocol (“SIP”) to simple object access protocol (“SOAP”) for communicating because it would change Dahlen’s principle of operation “to have intermediaries communicate using the SOAP protocol,” in accordance with claims 3, 5, 11, and 21. App. Br. 10-11; Reply Br. 5—6. More specifically, Appellants argue “SOAP is not used as a protocol in Dahlen for transmission or communication,” but rather SIP is used as the protocol for transmission and communication — a SOAP action header in a SOAP envelope is carried by the SIP communication protocol. App. Br. 10 (citing Dahlen || 27, 30—31, 57; Figs. 1A—IB, 2, 13); see also Reply Br. 5—6. The Examiner finds that modifying Dahlen to incorporate the teachings of Hunt and Alspector does not change the principle of operation of Dahlen. Ans. 3^4; Final Act. 7—10. The Examiner finds Dahlen teaches or suggests “SOAP intermediaries . . . because they accept SOAP subscription messages and proxy a subscription on behalf of a client.” Ans. 3^4 (citing Dahlen Fig. 6 (604); || 10, 51—58 (finding Dahlen teaches “using intermediary proxy to parse and dispatch SOAP requests on behalf of a client endpoint”)). We are not persuaded by Appellants’ arguments. We agree with the Examiner that the combination, and Dahlen in particular, teaches or suggests 4 Appeal 2016-005431 Application 13/413,590 that intermediary devices communicate using SOAP, and thus, Dahlen is not modified so as to change its principle of operation. Dahlen Fig. 6, Tflf 10, 51—58. More specifically, Dahlen teaches or suggests intermediary devices communicate using SIP and SOAP by having a SIP message carry a SOAP envelope or payload within the SIP message. Id.', see also id. 1 53 (teaching an intermediary node’s (i) SOAP parser “parses SOAP headers which are inside a SOAP envelope carried by the SIP messages” and (ii) SOAP dispatcher “invoke[s] Web Services . . . associated with the SOAP headers which are addressed to the intermediary node”). Such a teaching is within the broadest reasonable interpretation of intermediary devices using SOAP to communicate — also using other protocols (e.g., SIP) in addition to SOAP to communicate is not precluded by the claims. (ii) Dahlen teaches looking inward Appellants argue that the Examiner impermissibility changes Dahlen’s principle of operation in making the proposed combination. App. Br. 13, 20—21; Reply Br. 10—11. Appellants contend Dahlen’s principle of operation is to “look[] to the SOAP envelope and does not look outward.” App. Br. 20; see also id. at 20-21 (citing Dahlen || 54—58) (arguing Dahlen teaches evaluating a SOAP Action header, “including for purposes of whether an application at a receiving intermediary will be invoked”); Reply Br. 10-11 (arguing Dahlen looks inward rather than querying peers). Appellants argue modifying Dahlen’s “intermediar[ies] to query each other” improperly changes Dahlen’s principle of operation. App. Br. 20—21. The Examiner finds that modifying Dahlen to incorporate the teachings of Hunt and Alspector does not change the principle of operation of Dahlen. Ans. 16—17. The Examiner finds Dahlen’s principle of operation 5 Appeal 2016-005431 Application 13/413,590 is “to manage the subscription^].” Ans. 17. The Examiner finds “[i]t is well known within the art... to query peer intermediaries to identify a peer intermediary having access to an object of interest.” Ans. 16 (citing Hunt 67—68) (finding Hunt “teaches an intermediary redirecting requests (after receiving a query) to other peer routers and locating state objects to help process the request”). The Examiner finds one of ordinary skill “would be motivated to utilize the teachings of Hunt in the Dahlen system in order to ease the processing load of a single intermediary device,” and “it would have been obvious ... to utilize the teachings of Hunt for maintaining a distributed architecture of intermediaries and to query peer intermediaries to identity a Peer Intermediary Device having Access to Data Flows.” Ans. 17. We are not persuaded that combining Dahlen with Hunt and Alspector changes the principle of operation of Dahlen. We agree with the Examiner that Dahlen’s principle of operation is not as narrow as Appellants allege (i.e., using the SOAP envelope received at the intermediary), but rather relates more broadly to “providing service subscription techniques associated with real-time composition of services in communications systems.” Dahlen || 2, 7, Abstract. Appellants provide no persuasive evidence contrary to this finding. See App. Br. 13, 20-21; Reply Br. 10-11; see also In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) (“Attorney’s argument in a brief cannot take the place of evidence.”). (Hi) Adding a timeout Appellants argue that “one of skill would not seek to modify Dahlen ... so that a timeout is introduced as recited in claims 7 and 12 because adding a timeout is contrary to the purpose of the real-time SIP communication sessions in Dahlen.” App. Br. 32—33 (citing Dahlen 127 6 Appeal 2016-005431 Application 13/413,590 arguing “embodiments provide ‘a solution to the need for real-time composition of services ... by a Session Initiation Protocol (SIP) transport binding for SOAP messages.’”). According to Appellants, in “real-time communication session[s] established using SIP[,]. . . delays are sought to be avoided and are unwanted during communication sessions, e.g., VoIP calls.” App. Br. 32. The Examiner finds that modifying Dahlen to incorporate the teachings of Hunt’s distributed architecture and state information (e.g., waiting for timeout) is not contrary to the purpose of SIP in Dahlen. Ans. 24—25 (citing Hunt Figs. 8—9; 167). “One of ordinary skill in the art would be motivated to utilize the teachings of Hunt to wait for a timeout in the Dahlen system in order to determine an intermediary peer with an object of interest.” Ans. 25. We are not apprised of Examiner error based on Appellants’ argument. Appellants again focus incorrectly on a narrow aspect of Dahlen (e.g., that SIP can be used) rather than the broader principle and teachings of Dahlen (i.e., providing service subscription techniques). Dahlen || 2, 7, Abstract. Furthermore, Appellants provide no persuasive evidence that utilizing a timeout period with Dahlen’s teachings is contrary to Dahlen’s real time communications, including the use of SIP. In re Pearson, 494 F.2d at 1405. For example, Appellants conjecture that a timeout period would be incompatible with SIP, despite SIP being packet based. (2) Addressins the claim elements Appellants argue the Examiner fails to make a prima facie rejection of claims 1, 2, and 6 because the Final Office Action fails to address specific claim language, and instead relies on the substance of a preceding finding as 7 Appeal 2016-005431 Application 13/413,590 to another claim which does not use the same language. App. Br. 13—16; Reply Br. 6—7. We are not persuaded by Appellants’ arguments. First, Appellants do not address persuasively that the Final Action fails to inform them effectively as to the rationale for the rejection — Appellants simply rely on the language between the claims not being identical without sufficient further explanation. 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. Chester v. Miller, 906 F.2d 1574, 1578 (Fed. Cir. 1990). Second, Appellants’ Reply does not address the substance of the Examiner’s findings made in the Answer (Ans. 4—7), which address the language used in claims 1, 2, and 6. Instead of ignoring the Answer’s findings, Appellants could have addressed in the Reply these findings or could have filed a petition to request that the Answer’s findings be designated as a new ground of rejection — Appellants did neither. See Manual of Patent Examining Procedure (MPEP) § 1207.03(b)3 (9th ed., Rev. 7, Nov. 2015). 3 “37 CFR 41.40 sets forth the exclusive procedure for an appellant to request review of the primary examiner’s failure to designate a rejection as a new ground of rejection via a petition to the Director under 37 CFR 1.181. This procedure should be used if an appellant feels an answer includes a new ground of rejection that has not been designated as such and wishes to reopen prosecution so that new amendments or evidence may be submitted in response to the rejection. However, if appellant wishes to submit only arguments, the filing of a petition under 37 CFR 1.181 would not be necessary because appellant may submit the arguments in a reply brief. Any such petition under 37 CFR 1.181 must be filed within two months from the entry of the examiner’s answer and prior to the filing of a reply brief.” MPEP § 1207.03(b) (9th ed., Rev. 7, Nov. 2015). 8 Appeal 2016-005431 Application 13/413,590 (3) Combining Dahlen, Hunt, and Alsvector Appellants argue the Examiner fails to provide proper motivation to combine the relevant teachings of Dahlen, Hunt, and Alspector, including with respect to claims 1,11, and 21. See App. Br. 16—17; Reply Br. 8. Appellants argue the Examiner, in providing motivation to combine the relevant teachings of the cited references, “has not provided a citation to the prior art as to where this motivation exists,” and thus, fails to provide adequate support for the rejection. App. Br. 17; see also Reply Br. 8. We are unpersuaded by Appellants’ argument. As the Supreme Court explained, obviousness does not require that the motivation to combine references be found explicitly within the references themselves. KSR Int 7 Co. v. Teleflex Inc., 550 U.S. 398, 419 (2007) (“The obviousness analysis cannot be confined by a formalistic conception of the words teaching, suggestion, and motivation, or by overemphasis on the importance of published articles and the explicit content of issued patents.”); see also id. at 418 (“As our precedents make clear, however, the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”). In addition, we are unpersuaded by Appellants’ arguments (App. Br. 16—17) that the Examiner provides different motivations for combining the references — rather, the Examiner provides (Ans. 10—11) multiple articulations of the same rationale (i.e., “will allow one of ordinary skill in the art to change anything at all on a server without notifying the end user,” “to not require an administrator to inform a client every time anything is changed on a server relating to the client or user”). We also are not 9 Appeal 2016-005431 Application 13/413,590 persuaded that the Examiner fails to provide rationale for making the combination for claim 21. See, e.g., Ans. 11—12. Appellants’ arguments do not persuade us that the Examiner has failed to provide “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). (4) Modification ofDahlen Appellants argue that the Examiner fails to make a prima facie case of obviousness with respect to claim 17, as well as claims 6, 10, and 18, because the Examiner “does not cite to anything in Dahlen as being modified by the teachings of Chen.” App. Br. 18; Reply Br. 9. “For example, the [Final Office Action] mentions ‘subscription rules’ and ‘subscription filters’ in the context of Chen but does not cite back to what in Dahlen is being modified by these subscription [rules] and subscription filters of Chen.” App. Br. 18 (citing Final Act. 15). The Examiner submits that a prima face case of obviousness has been made. Ans. 13—14; Final Act. 15. The Examiner finds that the combination of Dahlen, Hunt, and Alspector teaches or suggests “peer intermediary devices receive a subscription, and review and proxy a subscription,” in accordance with the claims. Ans. 13. To these teachings, the Examiner adds Chen’s teaching for claim 17’s updating subscription rules (Chen’s filters) by comparing previously received rules with subsequently received subscription rules. Id. (citing Chen|| 163—169, Fig. 2IB). More specifically, the Examiner finds it would have been obvious to one of ordinary skill in the art to modify the combination’s subscriptions with Chen’s teachings regarding “merging filters,” which would “allow one of ordinary skill in the art to remove duplicate or overlapping subscription rules 10 Appeal 2016-005431 Application 13/413,590 and to provide improved subscription rules.” Id. at 14; see also Final Act. 7—8 (citing numerous portions of Dahlen as teaching subscriptions with respect to claim 11, from which claim 17 depends). We are not persuaded by Appellants’ arguments. For example, the Examiner identifies modifying Dahlen’s teachings regarding subscriptions with Chen’s teachings. See Ans. 13; Final Act. 7—8. In addition, the Supreme Court has clearly articulated that a direct citation to a reference is not required for the obviousness analysis. KSR, 550 U.S. at 418 (“As our precedents make clear, however, the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”). Appellants do not address persuasively the Examiner’s findings, including in the Answer, and we also are unconvinced that the Examiner fails to inform Appellants effectively as to the rationale for the rejection. Cf. Chester, 906 F.2d at 1578. Our reasoning above also applies to Appellants’ similar arguments (App. Br. 23) made with respect to the Examiner allegedly failing to provide a direct citation to what in Dahlen is being modified by Alspector, with respect to the combination of Dahlen, Hunt, and Alspector for claims 1 and 11. (5) Combining Dahlen and Chen Appellants argue “one of skill would not be motivated by Chen’s filters to compare previously received SIP messages at an intermediary with subsequently received SIP messages at the intermediary because doing so is inconsistent with the SIP protocol, which uses IP communication protocol to create communication between two distinct points,” with respect to claims 6, 11 Appeal 2016-005431 Application 13/413,590 17, and 18. App. Br. 19; see also Reply Br. 9—10. Appellants further contend “SIP regards communication and setting up a session between endpoints so each SIP message is necessary to promote the session,” and that “additional overhead and complexity would be added at the intermediary” if storage and filtering is added thereto “without any gain as a SIP session is carried out in real-time.” App. Br. 19. The Examiner finds Dahlen and Chen’s teachings are properly combined. Final Act. 15—16; Ans. 14—15. The Examiner finds “[o]ne of ordinary skill in the art would be motivated to utilize the teachings of Chen in the Dahlen/Hunt/Alspector system in order to reduce extra traffic, extra processing, and extra storage required by the use of unnecessary filters that are already being fulfilled via overlap or duplication.” Final Act. 15. We find the Examiner provides “articulated reasoning [(e.g., reduce extra traffic, extra processing, and extra storage required by unnecessary filters)] with some rational underpinning to support the legal conclusion of obviousness.” Kahn, 441 F.3d at 988. We disagree with Appellants that the Examiner’s reasoning provides insufficient motivation to combine the relevant teachings of Dahlen, Hunt, and Alspector with Chen’s teachings — reducing unnecessary traffic, processing, and storage is a design incentive. See KSR, 550 U.S. at 417 (“When a work is available in one field of endeavor, design incentives and other market forces can prompt variations of it, either in the same field or a different one.”). Appellants’ arguments that the Examiner’s combination would be “inconsistent with the SIP protocol” and would be “without any gain,” is unsupported by record evidence. See Pearson, 494 F.2d at 1405 (“Attorney’s argument in a brief cannot take the place of evidence.”). 12 Appeal 2016-005431 Application 13/413,590 We similarly are unpersuaded by Appellants’ arguments (App. Br. 32) that it would be superfluous and not obvious to modify Dahlen’s intermediaries to consolidate rules “because Dahlen is using SIP communication, which has its own common protocol, so there would be no need to further modify this protocol with previously received SIP packets” — such arguments are mere attorney argument unsupported by record evidence and fail to address directly the Examiner’s proffered motivation to combine. Pearson, 494 F.2d at 1405. (6) Improver hindsight Appellants argue that the Examiner uses improper hindsight, which “is demonstrated by the motivations proposed . . ., which do not identify particulars of the primary reference that would allegedly be ripe for change by the second or third identified reference.” App. Br. 21—23, 30—31. Appellants argue that the Examiner’s proffered motivations are vague and lack septicity. Id. at 23. We are not apprised by Appellants’ arguments that the Examiner used impermissible hindsight in making the various combinations cited in the rejections. As discussed above, we find Appellants’ arguments alleging that the Examiner does not provide direct citations to what in Dahlen is being modified by the other references in the combinations unpersuasive. See, e.g., supra § 3; see also In re McLaughlin, 443 F.2d 1392, 1313—14 (CCPA 1971) (“Any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but so long as it takes into account only knowledge which was within the level of ordinary skill. . . and does not include knowledge gleaned only from applicant’s disclosure, such a reconstruction is proper.”). Appellants argue that the Examiner “relies on 13 Appeal 2016-005431 Application 13/413,590 information gleaned solely from Applicant’s specification to make the combination,” but this argument is unsupported by the record evidence. Pearson, 494 F.2d at 1405; see also supra § 3. (7) Subscription Appellants argue that the combination of Dahlen, Hunt, and Alspector fails to teach or suggest “managing a proxy for a client management application subscription such that the client management application is not aware of change in its subscription,” as recited in claims 1 and 11. App. Br. 27—29. More specifically, Appellants argue Alspector fails to teach the claimed subscription, and instead Alspector teaches a spam filter “applied to unopened mail in a user’s mailbox” to filter out “unwanted spam from arriving or residing at a user’s inbox.” App. Br. 27 (citing Alspector col. 14, 11. 7—21). Appellants contend that spam filtering differs from a subscription, which “include[s] subscribing in some way or manner - e.g., a request or an indication of interest or predication on an advance order. Conversely, an email, in and of itself, without more, is sent to a recipient without the need for an earlier subscribing action or indication of interest.” Id. at 27—28. Appellants also argue that Alspector teaches blocking unwanted or unrequested spam, in contrast to a subscription, which is desired or sought after. Id. at 28; see also id. at 29 (providing definitions for filtering contrasted with subscription). The Examiner finds that the combination teaches the disputed limitation. Final Act. 9—10; Ans. 21—22. More specifically, the Examiner finds Alspector teaches or suggests a server managing email spam filters (i.e., subscriptions) and “performing changes in the subscription ([i.e.,] retraining of global filter) without a particular client having any part in the 14 Appeal 2016-005431 Application 13/413,590 process (either actively changing the subscription themselves or being notifying of a change).” Final Act. 9 (citing Alspector Fig. 3; col. 13,1. 4 — col. 14,1. 6). The Examiner finds that “a spam filter and ‘subscriptions’ are equivalent to one of ordinary skill in the art, as they both are a set of rules dictating which information/messages should or should not be received.” Ans. 21. The Examiner also finds that one of ordinary skill in the art would also understand that “the concepts of a filter and subscription to be synonymous in this context.” Id. at 21—22 (citing Internet Society RFC4660, Functional Description of Event Notification Filtering, § 3.3 (Sept. 2006)). We are not persuaded by Appellants’ arguments. We agree with the Examiner’s findings that the combination, and Alspector in particular, teaches or suggests the disputed limitation, including with respect to the claimed subscription. Alspector Fig. 3; col. 13,1. 4 —col. 14,1. 6. Alspector’s teaching of a filter is within the scope of the broadest reasonable interpretation of subscription — the spam filter is managed to allow certain emails through, as well as block certain emails. Id.', see also id. col. 13, 11. 42-46 (“For example, if the majority of e-mail users change a particular e-mail’s classification to spam or, conversely, the majority of users change it to legitimate, then the e-mail and its new classification may be chosen as retraining data.” (emphasis added)). Further, users themselves select legitimate emails (which types are used for receiving emails of the same types) which is akin to subscribing to a service. Alspector Fig. 3; col. 13, 1.4-col. 14,1. 6. (8) Combination’s teachings Appellants argue that certain limitations are missing from the combination of Dahlen, Hunt, and Alspector, but do so while focusing on the 15 Appeal 2016-005431 Application 13/413,590 teachings of these references individually rather than the combination’s teachings. App. Br. 24—27, 32—33; Reply Br. 12—13. For example, Appellants argue with respect to claim 21 that the combination fails to teach or suggest “at a second SOAP intermediary network device, receiv[ing] a subscription request. . . and upon determining that data flows for the subscription of the subscription request have been seen by the second intermediary device, accepting] responsibility for collecting data flows for the subscription” because Dahlen’s “data flows are not collected in the SIP communication scheme,” “[t]he SIP packets are simply reviewed and passed along using the SIP protocol,” and “[t]here is no acceptance of responsibility collection of data at an intermediary or determination regarding data flows.” App. Br. 25 (citing Dahlen Fig. 6 (604); 11 10, 46,51-58). The Examiner, however, finds that the combination (and more specifically, Dahlen and Hunt’s combined teachings) teaches or suggests this disputed limitation. Ans. 18—20; Final Act. 13—14; see also Ans. 19 (citing Dahlen Fig. 6 (602); H 51—58, 86) (finding Dahlen teaches or suggests “receiving a subscription request at [a] second intermediary device from a peer intermediary device, using SOAP for receipt of [the] subscription request”); id. at 19-20 (citing Hunt Figs. 8—9; 1 67) (finding Hunt teaches or suggests “querying peer intermediaries to identify the object of interest (subscription data) is stored at another intermediary (seen by the second peer intermediary) and to then delivery the object of interest (accept responsibility for the subscription request)”). Similarly, Appellants argue (App. Br. 26—27) that the Examiner errs in rejecting claims 1 and 11 because Alspector addresses an email server, 16 Appeal 2016-005431 Application 13/413,590 rather than a proxy and an intermediary. Appellants incorrectly focus on Alspector instead of addressing persuasively the combined teachings of Alspector, Dahlen, and Hunt. Id. The Examiner bases the rejection on the combined teachings. Ans. 20-21 (basing the rejection on, inter alia, Dahlen’s teaching of “a SOAP intermediary device receiving management data for a subscription using SOAP,” Hunt’s teaching of having a “distributed architecture of the intermediaries and querying intermediaries to identify a peer having object of interest,” and Alspector’s teaching of a server “manag[ing] subscriptions such that [a] client application is not aware of a change in its subscriptions”). We are not persuaded by Appellants’ arguments above, which incorrectly focus on the teachings of individual references rather than the combined teachings of the references in the combination. In re Merck & Co., 800 F.2d 1091, 1097 (Fed.
