REYNOLDS and KIRK HARGREAVES Appeal 2016-003627 Application 12/195,351 Technology Center 2600 Before JEFFREY S. SMITH, MICHAEL M. BARRY, and AARON W. MOORE, Administrative Patent Judges. MOORE, Administrative Patent Judge. DECISION ON APPEAL Appeal 2016-003627 Application 12/195,351 STATEMENT OF THE CASE Appellants1 appeal under 35 U.S.C. § 134(a) from a Final Rejection of claims 1—26, which are all of the pending claims. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. THE INVENTION The application is directed to “[a] capacitive sensing device for sensing a user input [that] comprises a resistive sheet, a plurality of electrodes, at least one sensing node, and at least one charge integrator.” (Abstract.) Claim 1, reproduced below, is representative: 1. A capacitive sensing device for sensing a user input, said device comprising: a resistive sheet; a plurality of electrodes disposed on a plurality of edge regions of said resistive sheet and configured for concurrently applying different excitation voltages to different edge regions of said resistive sheet such that a substantially steady state voltage gradient is established on said resistive sheet, wherein at least one of said different excitation voltages is a negative excitation voltage and at least one of said different excitation voltages is a positive excitation voltage; at least one sensing node disposed on at least one of said plurality of edge regions of said resistive sheet and configured for sensing a resulting charge on said resistive sheet after establishment of said steady state voltage gradient and a cessation of application of said different excitation voltages; and 1 Appellants identify Synaptics Incorporated as the real party in interest. (See App. Br. 1.) 2 Appeal 2016-003627 Application 12/195,351 at least one charge integrator coupled to said at least one sensing node and configured for measuring said resulting charge to produce a measurement. THE REFERENCES AND THE REJECTION Claims 1—26 stand rejected under 35 U.S.C. § 103(a) as unpatentable over Geaghan (US 2009/0167326 Al; published July 2, 2009), Geaghan (US 2009/0127003 Al; published May 21, 2009), and Baxter (US 2005/0099188 Al; published May 12, 2005). (See Final Act. 2—17.) APPELLANTS’ CONTENTIONS Appellants argue the rejections of claims 1—9 are in error for the following reasons: 1. “[B]y (1) applying a single excitation voltage, or (2) applying different excitation voltages that are the same polarity, Geaghan ’326 teaches away from or at minimum is silent with respect to ‘a plurality of electrodes . . . configured for concurrently applying different excitation voltages . . . wherein at least one of said different excitation voltages is a negative excitation voltage and at least one of said different excitation voltages is a positive excitation voltage,’ ... as recited in Claim 1.” (See App. Br. 12, emphasis omitted.) 2. “[B]y being silent in regards to the polarity of the excitation voltages, Geaghan ’003 does not teach ‘a plurality of electrodes . . . configured for concurrently applying different excitation voltages . . . wherein at least one of said different excitation voltages is a negative excitation voltage and at least one of said different excitation voltages is a 3 Appeal 2016-003627 Application 12/195,351 positive excitation voltage,’ as claimed.” (See App. Br. 12, emphasis omitted.) 3. “Baxter does nothing to cure the . . . deficiencies of Geaghan ’326 and Geaghan ’003” because “an alternating voltage does not teach or suggest ‘concurrently applying different excitation voltages to different edge regions’ or ‘wherein at least one of said different excitation voltages is a negative excitation voltage and at least one of said different excitation voltages is a positive excitation voltage.’” (App. Br. 12—13.) 4. “Geaghan ’326 does not teach ‘sensing a resulting charge on said resistive sheet after establishment of said steady state voltage gradient and a cessation of application of said different excitation voltages,’ as claimed.” (App. Br. 13, emphasis omitted.) 5. “Geaghan ’003 does not overcome the deficiencies of Geaghan ’326 because the combination of Geaghan ’326 and Geaghan ’003 changes the principle operation of Geaghan ’326.” (App. Br. 14.) Appellants repeat, more or less verbatim, one or more of these arguments for the remaining claim sets. (See App. Br. 16—36.) ANALYSIS Contention 1 Appellants’ argument that “Geaghan ’326 teaches away” (App. Br. 26) is unpersuasive because simply teaching another way is not “teaching away.” See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004) (“The prior art’s mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed.”). 4 Appeal 2016-003627 Application 12/195,351 Contention 2 Appellants’ second argument, that Geaghan ’003 is “silent in regard to the polarity of the excitation voltages” (App. Br. 27) is ineffective because the Examiner relies on Baxter for that subject matter. (See Final Act. 4 (“Baxter teaches . . . excitation voltages applied are different and at least one of said excitation voltages is a negative excitation voltage and at least one of said different excitation voltages is a positive excitation voltage.”).) Contention 3 The Final Action cited Geaghan ’003 as satisfying the “concurrently applying” claim language. (See Final Act. 3.) Appellants assert that “applying a positive voltage and then later applying a negative voltage” is not sufficient to teach or suggest the “concurrently” limitation. (Reply Br. 2.) We find this argument unpersuasive because the cited portions of Geaghan ’003, paragraphs 29-32 and 91 and Table 1, describe generation of a voltage gradient on a sensor where two of the four voltages are 0 and two are +VCC. Thus, the reference teaches concurrent application of two different voltages, for example, 0V at point UF and +VCC at point UR. As noted above, the Examiner relies on Baxter for the different polarities. Contention 4 Appellants next argue that “Geaghan ’326 . . . describes] that capacitance is measured at the comers of its sensor while the excitation voltages are being applied rather than after the cessation of their application.” (App. Br. 28.) This contention fails to show error because the Examiner relies on Geaghan ’003 for this feature and, as the Examiner explains, “Geaghan (’003) teaches a method for determining touch position where nodes (UF,UP,FF,FR) are used to produce a voltage gradient to store 5 Appeal 2016-003627 Application 12/195,351 a charge on the capacitor and once the charge[] is stored the nodes (UL,UP,LL,LR) are turned off and the charge is measured.” (Ans. 5, citing Geaghan’003 1129-31.) Contention 5 Finally, Appellants argue that “Geaghan ’003 does not overcome the deficiencies of Geaghan ’326 because the combination of Geaghan ’326 and Geaghan ’003 changes the principle operation of Geaghan ’326.” (App. Br. 29.) We agree with the Examiner, however, that “the combination of Geaghan (’326) and (’003) would not change the principal operation because the structure of the two panels are the same, [and] the combination would simply result in an alternative driving method for the panel.” (Ans. 9.) Conclusion As we find Appellants’ arguments insufficient to show Examiner error, we sustain the Section 103(a) rejections of claims 1—26. DECISION The rejections of claims 1—26 are 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 6 Copy with citationCopy as parenthetical citation
