HUGHES, JOHNNY A. KUMAR, and MATTHEW J. McNEILL, Administrative Patent Judges. KUMAR, Administrative Patent Judge. DECISION ON APPEAL This is a decision on appeal under 35 U.S.C. § 134(a) of the Final Rejection of claims 1, 2, 4---6, 8-10, 12-14, 16-18, and 20-50. 1 We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM the Examiner's rejection of these claims. 1 Claims 3, 7, 11, 15, and 19 were previously cancelled. Appeal2014-006145 Application 12/328,606 INVENTION The invention is directed to managing handover failure in wireless communication. (Spec. i-f 1.) Claim 1 is illustrative and is reproduced below: A method for managing a wireless communication handover operable upon a user equipment, comprising: identifying, by the user equipment, a handover failure in relation to transferring of the user equipment among base stations; and selecting, by the user equipment, an optimized cell in which to transfer the user equipment when the handover failure is identified, wherein the user equipment selects the optimized cell by evaluating at least one cell characteristic and selecting the cell based on a result of the evaluation.

(Final Act. 4.) Claims 2, 6, 10, 14, and 18 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Fischer, Xu, and Wei. (Final Act. 13.) Claims 4, 8, 12, 16, and 20 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Fischer, Xu, and '398. (Final Act. 15.) 2 Appeal2014-006145 Application 12/328,606 Claims 21-23, 25-29, 31-35, 37--41, 43--47, 49, and 50 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Fischer and Lee. (Final Act. 16.) Claims 24, 30, 36, 42, and 48 are rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Fischer, Lee, and '398. (Final Act. 26.) ISSUES Did the Examiner err in finding that the combination of Fischer and Xu teaches or suggests "wherein the user equipment selects the optimized cell by evaluating at least one cell characteristic and selecting the cell based on a result of the evaluation" as recited in claim 1 and corresponding limitations of claims 5, 9, 13, and 17? Did the Examiner err in finding that the combination of Fischer and Lee teaches or suggests "instructing the user equipment on at least one of a cell upon which to transfer and a frequency to use based upon the anticipated handover failure" as recited in claim 21 and corresponding limitations of claims 27, 33, 39, and 45? ANALYSIS Claims 1, 5, 9, 13, and 17 We select claim 1 as representative of the group of claims comprising claims 1, 5, 9, 13, and 17 as Appellant has not argued any of the other claims in this group with particularity. 37 C.F.R. § 41.37(c)(l)(iv). Claim 1 recites "wherein the user equipment selects the optimized cell by evaluating at least one cell characteristic and selecting the cell based on a 3 Appeal2014-006145 Application 12/328,606 result of the evaluation." Independent claims 5, 9, 13, and 17 recite corresponding limitations. Appellant argues Fischer fails to teach or suggest "the [user equipment (UE)] selects the right target cell based on a result of evaluation of a cell characteristic." (App. Br. 11 (emphasis omitted).) We agree with the Examiner that Fischer's paragraphs 27, 28, and 44 teach that the source eNB makes a handover decision based on measurements reported by the user equipment (UE). (Ans. 7-8.) The measurements reported by the UE are within the scope of the evaluated cell characteristics as recited in claim 1. Appellant argues Fischer teaches the source eNB selects the target eNB while the claims require the UE select the target cell. (Reply Br. 6.) However, one cannot show nonobviousness by attacking references individually when the rejection is based on a combination of references. In re Keller, 642 F.2d 413, 425 (CCPA 1981). The Examiner finds Xu teaches the UE selects an optimized cell. (Ans. 8.) We agree with the Examiner. Xu's paragraph 34 teaches the UE selects the cell with the best signal quality. (Ans. 10-11.) The signal quality is within the scope of the evaluation of "cell characteristics" recited in claim 1. Appellant argues the Examiner has not provided a legally sufficient reason for combining the utilized references to reject the claims. (App. Br. 9.) Appellant further argues the Examiner is using impermissible hindsight in combining Fischer and Xu because Fischer deals with procedures during a radio link failure of a handover procedure, but Xu only deals with procedures for establishing an initial service connection. (App. Br. 13.) The Examiner disagrees finding sufficient motivation has been provided from Xu abstract to combine Fischer and Xu for the purpose of increasing service 4 Appeal2014-006145 Application 12/328,606 access probability and improving service quality. (Ans. 3.) Specifically, the Examiner finds motivation to combine Fischer and Xu "in order to greatly increase service access probability and improve service quality, thus increasing subscribers' satisfaction toward services and promoting service expansion and application (Xu, abstract)." (Ans. 3; Final Act. 6.) We find the Examiner's explicit motivation to combine the references is reasonable. Appellant does not address the Examiner's explicit motivation to combine. (See App. Br. 9, 13; Reply Br. 9.) Accordingly, we are unpersuaded of error in the Examiner's motivation to combine Fischer and Xu. Accordingly, we sustain the Examiner's rejection of claims 1, 5, 9, 13, and 17. Dependent Claims 2, 6, 10, 14, and 18 Regarding claims 2, 6, 10, 14, and 18, Appellant argues Wei "fails to overcome the shortcomings in the teachings of Fischer and Xu noted above." (App. Br. 14.) However, we find no deficiencies in the Examiner's rejection of base claims 1, 9, and 17 based on Fischer and Xu. Therefore, by the preponderance of the evidence, we are not persuaded the Examiner erred. Accordingly, we sustain the rejection of dependent claims 2, 6, 10, 14, and 18. Dependent Claims 4, 8, 12, 16, and 20 Regarding claims 4, 8, 12, 16, and 20, Appellant argues '398 "fails to overcome the shortcomings in the teachings of Fischer and Xu noted above." (App. Br. 14.) However, we find no deficiencies in the Examiner's rejection of base claims 1, 9, and 17 based on Fischer and Xu. Therefore, by the 5 Appeal2014-006145 Application 12/328,606 preponderance of the evidence, we are not persuaded the Examiner erred. Accordingly, we sustain the rejection of dependent claims 4, 8, 12, 16, and 20. Claims 21-23, 25--29, 31-35, 37-41, 43-47, 49, and 50 We select claim 21 as representative of the group of claims comprising claims 21-23, 25-29, 31-35, 37--41, 43--47, 49, and 50 as Appellant has not argued any of the other claims in this group with particularity. 37 C.F.R. § 41.37(c)(l)(iv). Claim 21 recites "instructing the user equipment on at least one of a cell upon which to transfer and a frequency to use based upon the anticipated handover failure." Independent claims 27, 33, 39, and 45 recite corresponding limitations. Appellant argues "Fischer fails to teach or suggest that the source eNB instructs the UE at all in an anticipated radio link failure scenario." (App. Br. 15-16 (underline added).) Appellant's contentions are not commensurate in scope with the recited language of claim 21. Claim 21 recites instructing the UE "based upon the anticipated handover failure" but does not require instructions to the UE "during" or "in" the handover failure. The Examiner finds Fischer's paragraphs 28-34 teach the source eNB instructing the UE to transfer to the target eNB via the HANDOVER COMMAND message. (Ans. 16-17.) We agree with the Examiner that the HANDOVER COMMAND to the UE is instructing the UE on a cell upon which to transfer as recited in claim 21. See id. The Examiner further finds Fischer's paragraph 66 teaches anticipating handover failure. (Ans. 18.) In particular, the Examiner cites Fischer's paragraph 66 teaching "it is possible 6 Appeal2014-006145 Application 12/328,606 to anticipate [a radio link failure] and to systematically initiate handover procedures to these most probable target cells." Id. We agree with the Examiner that anticipating a radio link failure corresponds to anticipating a handover failure as recited in claim 21. See id. Appellant argues that the anticipated handover failure of Fischer's paragraph 66 is a separate embodiment and may not be combined with Fischer's paragraphs 28-32, which teach the source eNB instructing the UE via the HANDOVER COMMAND. (See Reply Br. 13.) Appellant's arguments are unpersuasive for two reasons. First, while anticipation rejections under 35 U.S.C. § 102 may not combine features from separate embodiments, see Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008), the rejection of claims 21 et seq. is based on obviousness under 35 U.S.C. § 103(a). (See Final Act. 16-28.) Second, the different scenarios of Fischer's paragraphs 28-32 (corresponding to figure 3) and paragraph 66 (corresponding to figure 4) are not separate embodiments. Fischer's paragraphs 62---63 teach, "A handover process in case of radio link failure is depicted in FIG. 4 .... The beginning of the procedure up to step S6 is quite similar to that of the procedure discussed above with reference to FIG. 3 and will not be described again here." Thus, the description of Fischer's paragraph 66 relating to the radio link failure scenario includes within it the description the procedure of Fischer's figure 3. Thus, the anticipated handover failure scenario of Fischer's paragraph 66 is not a separate embodiment from the subject matter of Fischer's paragraphs 28-32. Appellant argues that Lee fails to overcome the above discussed shortcomings of Fischer. (App. Br. 16-17; Reply Br. 13-15.) However, as discussed above, we find no deficiency in the Examiner's findings in regard 7 Appeal2014-006145 Application 12/328,606 to Fischer. Therefore, by the preponderance of the evidence, we are not persuaded the Examiner erred. For all of the above reasons, we sustain the rejection of dependent claims 21-23, 25-29, 31-35, 37--41, 43--47, 49, and 50. Dependent Claims 24, 30, 36, 42, and 48 Regarding claims 24, 30, 36, 42, and 48, Appellant argues '398 "fails to overcome the shortcomings in the teaching[ s] of Fischer and Lee noted above." (App. Br. 17.) However, we find no deficiencies in the Examiner's rejection of base claims 21, 27, 33, 39, and 45 based on Fischer and Lee. Therefore, by the preponderance of the evidence, we are not persuaded the Examiner erred. Accordingly, we sustain the rejection of dependent claims 24, 30, 36, 42, and 48. DECISION The Examiner's decision to reject claims 1, 2, 4---6, 8-10, 12-14, 16- 18, and 20-50 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 )(iv). AFFIRMED 8 Copy with citationCopy as parenthetical citation
