WHITEHEAD, JR., ERIC S. FRAHM, and ANDREW J. DILLON, Administrative Patent Judges. FRAHM, Administrative Patent Judge. DECISION ON APPEAL Appeal 2010-011663 Application 10/511,492 2 STATEMENT OF THE CASE Introduction Appellant appeals under 35 U.S.C. § 134(a) from a final rejection of claims 1-17. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Exemplary Claim Exemplary independent claim 1 under appeal, with emphasis added to disputed portions of the claim, reads as follows: 1. A circuit arrangement for a vehicle for generating at least two DC output voltages from at learnt one DC input voltage, wherein the DC output voltages are smaller than the DC input voltage, the circuit arrangement comprising: a voltage regulator for generating the DC output voltages, to supply operating power to a set of circuit elements used for operating the vehicle, from a voltage regulator input, a DC/DC converter for converting the DC input voltage to a lower voltage, the DC/DC converter configured to be switched on or off responsive to an on-off signal and to supply the lower voltage to the voltage regulator input as a source for generating the DC output voltages, and a logic circuit configured to provide the on-off signal to the DC/DC converter in response to an idle state in which the set of circuit elements are switched off, the logic circuit further configured to receive the DC input voltage to power the logic circuitry when the DC/DC converter is switched off. Appeal 2010-011663 Application 10/511,492 3 The Examiner’s Rejection1 The Examiner rejected claims 1-17 as being unpatentable under 35 U.S.C. § 103(a) over Appellant’s Admitted Prior Art found at page 1, lines 7-19 (hereinafter “AAPA”), and Kawaguchi (US 5,793,189). Ans. 3-6. Principal Issue on Appeal Based on Appellant’s arguments in the Briefs, the following principal issue is presented on appeal: Did the Examiner err in rejecting independent claims 1-17 as being obvious over the combination of AAPA and Kawaguchi because Kawaguchi, and thus the combination, fails to teach or suggest the logic circuit recited in representative claim 1? ANALYSIS We have reviewed the Examiner’s rejection in light of Appellant’s contentions in the Appeal Brief (App. Br. 4-8) and the Reply Brief (Reply Br. 2-11) that the Examiner has erred. We disagree with Appellant’s conclusion. We adopt as our own (1) the findings and reasons set forth by the Examiner in the action from which this appeal is taken (Ans. 3-6), and (2) the reasons set forth by the 1 Appellant does not present separate patentability arguments as to individual ones of claims 1-17 on appeal in the Appeal Brief (see generally App. Br. 4-8), and Appellant makes reference to claim 1 in some portions of the Reply Brief by (Reply Br. 2, 5, and 6). Because independent claim 1 contains similar subject matter as remaining independent claims 5 and 13, primarily that of a logic circuit (claim 5 recites “an on-off logic circuit configured to generate a switching signal” and claim 13 recites “control circuitry configured to generate the on-off signal”) and a DC/DC converter, we select claim 1 as representative of the group of claims 1-17 on appeal. Appeal 2010-011663 Application 10/511,492 4 Examiner in the Examiner’s Answer in response to Appellant’s Appeal Brief (Ans. 7-12). We concur with the conclusion reached by the Examiner. We agree with the Examiner’s findings and determinations regarding independent claim 1 (Ans. 3-4 and 7-12). Kawaguchi teaches or suggests the logic circuit recited in claim 1 (col. 5, ll. 38-44; col. 6, ll. 56-65; see e.g. starting control input terminal ST) for providing an on/off signal to a DC/DC converter 6 (see Fig. 1; col. 5, ll. 56-62). We also agree with the Examiner that the limitations of claim 1 do not require that (i) the voltage actually received by the logic circuit is exactly the same as the DC input voltage being supplied to the DC/DC converter (Ans. 7-8), and/or (ii) the logic circuit must always receive the DC input voltage (Ans. 10), instead, the claim merely recites that the logic circuit is “configured to receive the DC input voltage” (claim 1). With regard to Appellant’s argument (Reply Br. 9-10) concerning the lack of motivation to combine AAPA with Kawaguchi, we note that Appellant does not present any arguments regarding motivation in the Appeal Brief, and instead presents this argument for the first time in the Reply Brief. “Any bases for asserting error, whether factual or legal, that are not raised in the principal brief are waived.” Ex parte Borden, 93 USPQ2d 1473, 1474 (BPAI 2010) (informative); see also Optivus Tech., Inc. v. Ion Beam Appl’ns. S.A., 469 F.3d 978, 989 (Fed. Cir. 2006) ((“[A]n issue not raised by an appellant in its opening brief . . . is waived.”) (citations and quotation marks omitted)). Here, the Examiner’s finding(s) in the Examiner’s Answer that AAPA and Kawaguchi are (i) analogous and from the same field of endeavor of Appeal 2010-011663 Application 10/511,492 5 vehicle power distribution systems, and (ii) can be combined “in order to reduce power consumption in the vehicle by turning off the converter when it is not needed” (Ans. 4 (citation omitted)) are not challenged in the Appeal Brief (see generally App. Br. 4-8). Indeed, because the Examiner recognizes in the response to the Appeal Brief that Appellant “do[es] not challenge the combination of references” (Ans. 7), we find nothing that would have prompted the new argument in the Reply Brief. Appellant could have made the argument in the Appeal Brief. The term “Reply Brief” is exactly that, a brief in reply to new rejections or new arguments set forth in an Examiner’s Answer. Appellant may not present arguments in a piecemeal fashion, holding back arguments until an examiner answers the original brief. To the contrary, such bases for asserting error are waived. See 37 C.F.R. § 41.37(c)(1)(iv). With regard to Appellant’s arguments (Reply Br. 10-11) concerning Figure 5 of Kawaguchi, we note that the appropriate venue for Appellant to object to any new grounds of rejection of claims 1-17 under § 103(a) is by petition to the Supervisory Patent Examiner under MPEP § 1002.02(d), Petitions and Matters Decided by Supervisory Patent Examiners [R-2], Rev. 2, May 2004. No such petition has been filed in the instant case. CONCLUSION The Examiner has not erred in rejecting independent claims 1-17 as being obvious over the combination of AAPA and Kawaguchi because Kawaguchi teaches or suggests the logic circuit recited in representative claim 1. Appeal 2010-011663 Application 10/511,492 6 DECISION The Examiner’s rejection of claims 1-17 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)(1)(iv). AFFIRMED llw Copy with citationCopy as parenthetical citation
