ANALYSIS Only those arguments actually made by Appellants have been considered in this Decision. Arguments that Appellants did not make in the Briefs have not been considered and are waived. See 37 C.F.R. § 41.37(c)(l)(iv). We are not persuaded by Appellants' contentions of Examiner error (App. Br. 5-13; Reply Br. 1--4). We adopt as our own the findings and reasons set forth by the Examiner in the action from which this appeal is taken (Non-Final Act. 4--12) and as set forth by the Examiner in the Answer (Ans. 12-15). However, we highlight and address specific arguments and findings for emphasis as follows. 3 Appeal2014-008239 Application 12/753,091 Appellants argue the Examiner erred in finding the combination of Kiml and Kim2 teaches or suggests the disputed limitation of claim 1 principally because Kim2 teaches impedance adjusting for all signals. App. Br. 8-9. In contrast, claim 1 expressly recites "each of the sub transmission lines does not [(comprise at least one impedance adjusting unit)]." Id. We are unpersuaded the Examiner erred. The Examiner finds, and we agree, Kiml teaches, inter alia, a plurality of signal lines alternating with a plurality of control lines in the active region of a substrate. Non-Final Act 3--4 (citing Kiml Fig. 1); Ans. 12. Further, the Examiner finds, and we agree, Kim2 teaches, inter alia, a plurality of main transmission lines, positioned in the peripheral region, wherein each main transmission line comprises at least one impedance adjusting unit. Non-Final Act. 5---6 (citing Kim2, Figs. 1-3 and 5-8); Ans. 12-13. The Examiner explains that although Kim2 does not teach the lack of impedance adjustment on sub transmission lines located in the peripheral region, which are connected to control lines in the active region of a substrate, this is "for the simple reason that the circuit of Kim 2 does not have control lines and corresponding sub transmission lines." Ans. 13. The Examiner further explains it would have been suggested to the ordinary skilled artisan to exclude such impedance adjustment (as taught in Kim2) from the control lines of Kiml (in the proposed combination) because: Kim 1 teaches (e.g., Fig. 1; col. 3, lines 35 - 40; col. 4, lines 18 - 20) that the voltages supplied by the scan lines directly affect the transmittance of the first and second sub-pixels ((501) and (502)) via the respective TFTs ((601) and (602)), while the voltages supplied by the control lines affect the transmittance of only the second sub-pixels (502) and only indirectly, i.e., by switching on the corresponding TFT (701) and thereby adding the capacitance 4 Appeal2014-008239 Application 12/753,091 (Cst3) to (Cst2) (col. 4, lines 4- 28). Thus, the voltages provided by the control lines do not have to be accurately controlled as accurately as the voltages provided by the scan lines. As such, the Kim 1 - Kim 2 combination renders obvious that the control lines do not have to have equalized voltages applied to different control TFTs (701) (as long as the applied voltages exceed the minimum switch-on voltage of (701) to control the step- down/control capacitors (Cst3)) and hence do not require impedance adjusting units. Non-Final Act. at 6-7. Thus, the Examiner finds, and we agree, the combination of Kiml and Kim2 teaches or suggests main transmission lines (e.g., Kiml gate lines 101 and 102) modified to have impedance adjustment and arranged alternating with sub transmission lines (e.g., Kiml control lines 301 and 302) having no such impedance adjustment. Appellants additionally argue Kiml explicitly teaches control line 301 may be connected to the next stage gate line 102 (App. Br. 9 (citing Kim 4:12-13)) and; thus; contend "[s]ince Kim-I clearly teaches that the lines 301 and 302 are electrically connected to the gate line, the lines 301 and 302 ofKim-1 should be controlled in a manner similar to the gate lines [(101 and 102)]." Id. We do not agree. Kiml does not discuss the criticality of the signaling of any of lines 101, 102, 201, 201, 301, or 302. The Examiner relies on Kim2, in the proposed combination, for teaching the criticality of signaling on scan and data lines and the resultant need for impedance adjustment- i.e., "signal lines" such as gate lines 101 and 102 ofKiml. Control lines 301 and 302 in Kiml merely improve visibility of the rendered image by adjusting the charge on a pixel that is "on" (Kim 1 4: 16-1 7, 4: 24-- 26) - a pixel that is turned on or off by gate lines 101 and 102 and corresponding intersecting data lines 201 and 202 (Kim 1 Fig. 1 ). 5 Appeal2014-008239 Application 12/753,091 Furthermore, Appellants' contention that control line 302 may be connected to a next stage represents only one embodiment in Kiml. Kiml also discloses control lines 301 and 302 may be independent of gate lines 101 and 102. Kiml 4:26-28 ("Also, the charge control line 301 is not limited to the next stage gate line and may be an independently controlled line."). Appellants further argue the Examiner errs because, Even ifthe lines 301 and 302 of Kim-1 in certain embodiment is electrically independent from the gate lines 101 and 102, there is still no motivation or suggestion to configure a signal line without impedance adjustment according to the input signal type when applying the impedance compensating technique as taught by Kim-2. App. Br. 9-10. Specifically, Appellants contend "the prior art must provide a motivation or reason for the worker in the art, without the benefit of appellant's specification and the Office should not determine the claim invention obvious based on the hindsight of the Appellants' specification." Id. at 10. Appellants further contend Kim2 expressly teaches the impedance adjustment is applied to all signal lines to assure uniformity of impedance of all signal lines. Id. Thus, Appellants conclude, without benefit of hindsight of Appellants' Specification, the proposed combination would logically add impedance adjustment to all lines- including control lines of Kimi. Id.; see also Reply Br. 1-3 We remain unpersuaded of Examiner error. The Examiner reasons the ordinary skilled artisan would have been motivated to combine Kiml and Kim2 because "proper operation of the LCD device can be enabled by establishing a continuous electrical path from the signal driver to each pixel." Non-Final Act 6. Thus, the Examiner has articulated a reason for the 6 Appeal2014-008239 Application 12/753,091 proposed combination based on rational underpinnings. See KSR Int' I Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). The Court in KSR further holds, "the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ." Id. Appellants have not persuasively shown the Examiner's reasoning to be in error. Furthermore, as discussed supra, the Examiner finds Kim2 fails to discuss the presence or absence of impedance adjustment on the control lines because Kim2 does not have control lines but Kiml discloses control lines and signal lines both devoid of impedance adjustments. The 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 \'l/ould have suggested to those of ordinary skill in the art. In re Keller, 642 F .2d 413, 425 (CCP A 1981) (citations omitted, emphasis added). The Examiner finds the pixel unit circuit in Figure 1 of Kiml and that of Appellants' invention in Figure 3 are nearly identical and, thus, "routine circuit analysis" by an ordinary skilled artisan would naturally combine the impedance adjustment of Kim2 only to the scan/gate lines of Kiml. Ans. 12-13. The Examiner further finds, in addition to such routine circuit analysis, although the scan lines in Kiml directly control transmittance of both sub-pixels (501 and 502), as discussed supra, the control lines ofKiml only indirectly affect the transmittance of the second sub-pixel (502), and thus do not require the accurate voltage control of the 7 Appeal2014-008239 Application 12/753,091 scan lines. Ans. 13. Therefore, the Examiner has expressed further reasons based on rational underpinnings as motivation to combine the references and Appellants have not persuasively rebutted these findings. In view of the above discussion, we are not persuaded the Examiner erred in rejecting independent claim 1 or claims 2--4, 6-9, 14, and 15 argued together with claim 1. App. Br. 12. Furthermore, Appellants argue the Examiner erred in rejecting claim 5 and rejecting claims 10-13 for essentially the same reasons as claim 1 (App. Br. 12-13) and, thus, for the same reasons as claim 1, we are not persuaded of Examiner error in these rejections. Therefore, we sustain the rejections of claims 1-15. DECISION For the above reasons, the Examiner's decision rejecting claims 1-15 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
