CHEN, MONICA S. ULLAGADDI, and SCOTT E. BAIN, Administrative Patent Judges. ULLAGADDI, Administrative Patent Judge. DECISION ON APPEAL Appellants seek our review, under 35 U.S.C. § 134(a), of the Examiner's final rejection of claims 1, 2, 4, and 6-30. We have jurisdiction under 35 U.S.C. § 6(b ). We AFFIRM-IN-PART. 1 The real party in interest is Qualcomm, Inc. App. Br. 1. Appeal2017-009501 Application 14/214, 115 STATEMENT OF THE CASE The present invention relates to "wireless communication systems, and more particularly, to selection of mobile networks by access terminals or other devices." Spec. ,r 2. The independent claims on appeal are claims 1, 16, 24, and 30. Claim 1 is illustrative and is reproduced below (with emphasis added to a disputed limitation). 1. A method for network node selection of a user equipment (UE), the method comprising: receiving, from a home network, a message comprising a home network policy associated with network node selection; determining, by the UE, whether the home network policy has precedence over a visited network policy of a visited network based on an indication of precedence between the home network policy and the visited network policy in the message; and selecting a network node based on the home network policy in response to the determining that the home network policy has precedence over the visited network policy. REJECTION Claims 1, 2, 4, and 6-30 are rejected under 35 U.S.C. § 103 as obvious over Mustajarvi (US 2012/0309447 Al; Dec. 6, 2012) and Song (US 2007/0183410 Al; Aug. 9, 2007). Final Act. 2-8 (Sept. 21, 2016). ANALYSIS Independent Claims 1, 16, 24, and 30 and Dependent Claims 2, 8-15, 17, 21-23, 25, and 29 Appellants argue Mustajarvi and Song do not teach or suggest "determining, by a UE, whether the home network policy has precedence 2 Appeal2017-009501 Application 14/214, 115 over a visited network policy of a visited network based on an indication of precedence between the home network policy and the visited network policy in a message," as recited in independent claim 1. App. Br. 5. Specifically, Appellants contend that, although Song is cited as teaching the claimed message, Song "does not disclose or suggest an indication of precedence between a home network policy and a visited network policy in a message." Id. at 5---6 ( emphasis added). Appellants' argument is not responsive to the Examiner's specific findings. The Examiner finds Mustajarvi discloses a determination of "whether the home network policy has precedence over a visited network policy of a visited network." Final Act. 3 ( citing Mustajarvi ,r,r 6, 10, 11, 26, 29, 51 ). The Examiner further finds [I]n the same field of endeavor, [S]ong teaches --- precedence information, which indicates which domain selection information should be used among the domain selection information in the operator policy and the domain selection information in the user preferences, can be provided to the network entity or the UE (see par. 0056, 0062, 0085-0086). Note that receiving the precedence information requires signaling or some sort of message since the claimed message is generic (not[] a particular type message). Therefore, it would have been obvious for one of ordinary skill in the art at the time the application was filed to modify the teaching of Mastajarvi [sic] with that of Song so that ---- precedence information, which indicates which domain selection information should be used among the domain selection information in the operator policy and the domain selection information in the user preferences, can be provided to the network entity or the UE (see par. 0056). Id. at 3. We have reviewed Mustajarvi and Song, and concur in the Examiner's findings. Appellants' argument that Song is silent as to precedence between home and visited network policies amounts to an 3 Appeal2017-009501 Application 14/214, 115 individual attack on the references. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) ("[O]ne cannot show non-obviousness by attacking references individually where, as here, the rejections are based on combinations of references."). For the foregoing reasons, Appellants' arguments do not persuade us that the Examiner erred in finding the combination of Mustajarvi and Song teaches or suggests the limitations of claim 1. Therefore, we sustain the rejection of independent claim 1 and independent claims 16, 24, and 30, which recite commensurate limitations. As claim 1 is representative of dependent claims 2, 8-17, 21-25, 29, and 30 (see App. Br. 6), we also sustain the rejections of these claims. Dependent Claims 4, 18, and 26 Claim 4 depends from claim 1 and recites "determining the visited network policy has precedence based on receiving no indication of precedence in the message, and selecting the network node based on the visited network policy in response to determining the visited network policy has precedence over the home network policy." Each of claims 18 and 26 recites limitations commensurate in scope with claim 4, and each is "rejected on the same ground and motivation as claim 4." Final Act. 7 (claim 18), 8 ( claim 26). The Examiner finds Mustajarvi teaches the limitations recited in dependent claims 4, 18, and 26, and that "[ w ]hen the references are combined as shown above, the modified system will indicate that the home network policy has a precedence over that of the visited." Id. at 4 (citing Mustajarvi ,r,r 11, 29, 35-37, 76). Appellants contend "the Office Action acknowledges 'Mustajarvi does not explicitly teach about --- receiving a message, from a home 4 Appeal2017-009501 Application 14/214, 115 network' ... [and] [i]f Mustajarvi does not disclose receiving a message, Mustajarvi cannot possibly disclose receiving no indication of precedence in the message." App. Br. 6 (emphasis omitted); see Reply Br. 3--4. Appellants' argument is persuasive. The cited portions ofMustajarvi do not teach or suggest "receiving no indication of precedence in the message." See Mustajarvi ,r,r 11, 29, 35-37, 76; see Ans. 2-8. The Examiner's finding that "the modified system will indicate that the home network policy has a precedence over that of the visited" (see Final Act. 4) does not explain how the person of ordinary skill in the art would have understood the combined teachings of Mustajarvi and Song to teach or suggest no indication of precedence in the message. For the foregoing reasons, we are persuaded the Examiner erred in rejecting claim 4. Therefore, we do not sustain the rejection of claim 4. As claim 4 is representative of claims 18 and 26, we also do not sustain the rejections of these claims. See 37 C.F.R. § 41.37( c )(1 )(iv); App. Br. 6 (grouping these claims). Dependent Claims 6, 19, and 2 7 Claim 6 depends from claim 1, and recites "wherein the indication of precedence comprises an access node list, wherein the determining further comprises: comparing the visited network to entries in the access node list, determining the home network policy has precedence if the visited network does not match any of the entries in the access node list, and determining the visited network policy has precedence if the visited network matches any of the entries in the access node list." Each of claims 19 and 27 recites limitations commensurate in scope with claim 6 and each is "rejected on the same ground and motivation as claim 6." Final Act. 6 ( claim 19), 8 ( claim 5 Appeal2017-009501 Application 14/214, 115 27). The Examiner cites paragraphs 6, 11, 15, 29, 33, and 37 of Mustajarvi as teaching the limitations recited in dependent claims 6, 19, and 27. Appellants contend that the combination of Mustajarvi and Song fails to teach or suggest "determining the home network policy has precedence if the visited network does not match any of the entries in the access node list, and determining the visited network policy has precedence if the visited network matches any of the entries in the access node list." App. Br. 7; see Reply Br. 4. Specifically, Appellants argue that "the cited portions of Mustajarvi disclose determining whether the highest priority access network option of the selected policy has resulted in a successful connection, and if not, trying a next lower priority access network option of the selected policy." Id. Appellants further argue that the "cited portions also disclose selecting the highest priority valid policy for the visited network (Paragraph [0033]) and considering network selection policies provided by the home network before and after the first selection policy provided by the visited network (Paragraph [0037])." Id. Appellants' arguments are persuasive. Mustajarvi discloses that mobile communication device 2 receives information regarding the priority for accessing available access networks and selects a network according to existing network selection information or "by any other means available to the mobile device." Mustajarvi ,r 6. Mustajarvi further discloses that mobile communications device 2 applies the highest priority policy that satisfies validity conditions such as, for example, location. Id. ,r 9. Mustajarvi also discloses "global" policies valid only when the mobile communication device is roaming in a visited network and "local" policies valid only when the mobile communication device is located within the home network. Id. ,r 6 Appeal2017-009501 Application 14/214, 115 35. It is unclear, on this record, how the cited teachings of Mustajarvi would have suggested to the ordinarily skilled artisan that the precedence of the network is based on a comparison and matching or lack of matching. For the foregoing reasons, we are persuaded the Examiner erred in rejecting claim 6. Therefore, we do not sustain the rejection of claim 6. As claim 6 is representative of claims 19 and 27, we also do not sustain the rejections of these claims. See 37 C.F.R. § 4I.37(c)(l)(iv); App. Br. 7-8 (grouping these claims). Dependent Claims 7, 20, and 28 Claim 7 depends from claim 1 and recites "attempting to retrieve the visited network policy in response to determining the visited network policy has precedence; and selecting a network node based on the home network policy in response to failing to retrieve the visited network policy or retrieving no applicable visited network policy." Each of claims 20 and 28 recites limitations commensurate in scope with claim 7 and each is "rejected on the same ground and motivation as claim 7." Final Act. 6 (claim 20), 8 ( claim 28). The Examiner finds Mustajarvi's mobile communication device does not retrieve a visited network policy when it is within the home network. See Ans. 8. Appellants contend Mustajarvi does not teach or suggest "failing to retrieve the visited network policy or retrieving no applicable visited network policy" and selecting a network node in response thereto. App. Br. 8; Reply Br. 5-7. Specifically, Appellants argue Mustajarvi teaches a roaming mobile communication device that initiates a connection and successfully retrieves a policy from the visited operator Access Network Discovery and Selection Function (V-ANDSF). App. Br. 5---6. Appellants 7 Appeal2017-009501 Application 14/214, 115 further argue that the mobile communication device does not attempt to retrieve a visited network policy when not roaming, i.e., when within the home network. Id. at 7-8. We are not persuaded by Appellants' contention, because claim 7 recites "selecting a network node" responsive to alternative conditions, "failing to retrieve the visited network policy or retrieving no applicable visited network policy." Appellants' argument does not address the Examiner's finding that Mustajarvi's mobile communication device does not retrieve a visited network policy when it is within the home network. See Ans. 8. The Examiner need not also make specific findings that the combination of Mustajarvi and Song teaches "selecting a network node" responsive to the alternative condition of "failing to retrieve the visited network policy." We have reviewed Appellants' remaining arguments, all of which rely on issues we have addressed above. We are not persuaded for the reasons already discussed. For the foregoing reasons, we are not persuaded the Examiner erred in addressing claim 7. Therefore, we sustain the rejection of claim 7. As claim 7 is representative of claims 20 and 28, we also sustain their rejections. See 37 C.F.R. § 4I.37(c)(l)(iv); App. Br. 8 (grouping these claims). 8 Appeal2017-009501 Application 14/214, 115 DECISION We affirm the Examiner's decision to reject claims 1, 2, 7-17, 20-25, and 28-30. We reverse the Examiner's decision to reject claims 4, 6, 18, 19, 26, and 27. 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-IN-PART 9 Copy with citationCopy as parenthetical citation
