WINSOR, JEREMY J. CURCURI, and KEVIN C. TROCK, Administrative Patent Judges. CURCURI, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134(a) from the Examiner's rejection of claims 53-73. Non-Final Act. 1. We have jurisdiction under 35 U.S.C. § 6(b). Appeal2015-006068 Application 12/106,774 Claims 53, 55, 57, 58, 60, 62, 64, 65, 67, 69, 71, and 72 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Capurso (US 2009/0252491 Al; Oct. 8, 2009) and Davis (US 2005/0058118 Al; Mar. 17, 2005). Non-Final Act. 3---6, 7-9, 10-15. Claims 54, 61, and 68 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Capurso, Davis, and Bridges (US 2007 /0274718 Al; Nov. 29, 2007). Non-Final Act. 6. Claims 56, 63, and 70 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Capurso, Davis, and ITU-T Recommendation G.984.4. Non-Final Act. 7-8. Claims 59, 66, and 73 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Capurso, Davis, and Bhatia (US 2002/0131411 A 1; Sept. 19, 2002). Non-Final Act. 9-10. We affirm. STATEMENT OF THE CASE Appellants' invention relates to virtual local area network (VLAN) message tagging. Spec. i-f 2. Claim 53 is illustrative and reproduced below: 53. A method for retagging an upstream frame with a VLAN tag in an optical network termination (ONT) device of a passive optical network, wherein the ONT device is configured with a virtual local area network (VLAN) tagging operation configuration data management entity (ME) which organizes data associated with VLAN tagging, the method comprises: receiving an upstream frame having a VLAN tag, which includes a Tag Control Information (TCI) field with at least a priority value and a VLAN identifier (VID); 2 Appeal2015-006068 Application 12/106,774 matching both the priority value and the YID in the VLAN tag with values of a priority field and a VID field within a VLAN tagging operation table, wherein the VLAN tagging operation table is an attribute of the VLAN tagging operation configuration dataME; based on the matching, identifying a new priority value and a new VID within a corresponding VLAN priority operation field and a VID operation field in the VLAN tagging operation table; thereafter, adding a new VLAN tag to the received upstream frame by inserting the new priority value and the new VID into respective fields of the new VLAN tag; and sending the upstream frame with the new VLAN tag to an optical line terminal (OL T) of the passive optical network. ANALYSIS THE OBVIOUSNESS REJECTION OF CLAIMS 53, 55, 57, 58, 60, 62, 64, 65, 67, 69, 71, AND 72 OVER CAPURSO AND DAVIS The Examiner finds Capurso and Davis teach all limitations of claim 53. Non-Final Act. 3---6. The Examiner finds Capurso's insertion into the header GEMH 1 of the frame GEMF2 of a value indicative of the precedence of the Ethernet packet teaches the recited (claim 5 3): based on the matching, identifying a new priority value and a new VID within a corresponding VLAN priority operation field and a VID operation field in the VLAN tagging operation table; 1 Gigabit Passive Optical Network (GPON) Encapsulation Mode (GEM) Header. Capurso i-fi-f 11, 15. 2 GEM Frame. Capurso i-fi-f 11, 15. 3 Appeal2015-006068 Application 12/106,774 thereafter, adding a new VLAN tag to the received upstream frame by inserting the new priority value and the new VID into respective fields of the new VLAN tag[.] Non-Final Act. 4--5 (citing Capurso i-fi-192, 96); see also Capurso Figure 4 (insertion of value VG and value pG into header GEMH), i-f l 02 ("VG is a value indicative of the VLAN Identifier of the Ethernet packet EthP"), and i1 103 ("pG is a value indicative of the Ethernet packet priority value p"); and Ans. 2-7. Appellants present the following principal arguments: 1. Capurso merely teaches how to map the pG with the priority value p in the received Ethernet packet, and Capurso fails to teach how to identify a new priority value for the received Ethernet packet, based on the mapping results. Similarly, Capurso also specif[ies] that "VG is a value indicative of the VLAN identifier of the Ethernet packet EthP." See Capurso, i1 0102, lines 1-2. As such, Capurso fails to teach identifying new values for the received priority value p and VID in the Ethernet packet, based on these mapped values. App. Br. 6. 11. "[T]he mapping table in Davis is used to search a VLAN identifier that corresponds to the LLID of the upstream packet, and the mapping table in Davis cannot be used to identify any new priority value or new VID." App. Br. 7. We do not see any error in the Examiner's findings. Nor do we see any error in the Examiner's conclusion of obviousness. Regarding Appellants' argument (i), we agree with and adopt as our own the Examiner's finding that Capurso' s value pG discloses the recited (claim 53) "new priority value" and Capurso's value VG discloses the recited (claim 53) "new VID." Non-Final Act. 4--5; see also Ans. 4--5. 4 Appeal2015-006068 Application 12/106,774 Further, we also agree with and adopt as our own the Examiner's further explanation: Capurso et al. explains in i-f [0036] that in the prior art the GPON network is unable to distinguish between GEM frames transporting Ethernet packets with high and low precedence. Thus, inserting in a header field of the second data packet a value indicative of the precedence information as described in Capurso et al. i-f [0043] constitutes a new priority value and a new VID, as further explained in Capurso et al. i-f [0048], where it states "the encapsulating module is adapted to insert in a header field of the second data packet a value indicative of the precedence information". Ans. 4. Put another way, Capurso's values pG and VG are new values in a new tag as required by claim 53. See Capurso, Figure 4. Regarding Appellants' argument (ii), [t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that 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). Here, the Examiner finds Capurso teaches identifying a new priority value and a new VID. Non-Final Act. 4--5. The Examiner finds Davis teaches a table. Non-Final Act. 5-6 (citing Davis i-f 25). We agree with and adopt these findings as our own. We also agree with and adopt as our own the Examiner's reason for combining the references: it would have been obvious to a person of ordinary skill in the art at the time of the invention to combine a mapping table as taught by Davis et al. in the system of Capurso et al., by using an ONU that maintains a similar mapping table as the OLT. The motivation for having an ONU that maintains a similar mapping 5 Appeal2015-006068 Application 12/106,774 table as the OLT is to further enhance the system reliability and efficiency by having upstream filtering occurs at an ONU to support VLAN tagging option also during propagation along the passive optical network. Non-Final Act. 5---6; see also Ans. 5---6. Thus, Appellants' argument (ii) argues Davis individually where the Examiner has relied on the combined teachings of the references. Thus, Appellants' argument (ii) does not show any error in the Examiner's findings or in the Examiner's legal conclusion of obviousness. We, therefore, sustain the Examiner's rejection of claim 53, as well as claims 55, 57, 58, 60, 62, 64, 65, 67, 69, 71, and 72, which are not separately argued with particularity. THE OBVIOUSNESS REJECTION OF CLAIMS 54, 61, AND 68 OVER CAPURSO, DAVIS, AND BRIDGE Appellants do not present any additional arguments for the patentability of claims 54, 61, and 68. See App. Br. 8. We, therefore, sustain the Examiner's rejection of claims 54, 61, and 68. THE OBVIOUSNESS REJECTION OF CLAIMS 56, 63, AND 70 OVER CAPURSO, DAVIS, AND ITU-T RECOMMENDATION G.984.4 Appellants do not present any additional arguments for the patentability of claims 56, 63, and 70. See App. Br. 8. We, therefore, sustain the Examiner's rejection of claims 56, 63, and 70. 6 Appeal2015-006068 Application 12/106,774 THE OBVIOUSNESS REJECTION OF CLAIMS 59, 66, AND 73 OVER CAPURSO, DAVIS, AND BHATIA Appellants do not present any additional arguments for the patentability of claims 59, 66, and 73. See App. Br. 9. We, therefore, sustain the Examiner's rejection of claims 59, 66, and 73. DECISION The Examiner's decision rejecting claims 53-73 is 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 ). AFFIRMED 7 Copy with citationCopy as parenthetical citation
