Claim Rejections - 35 USC § 103 6. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 7. Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Woo et al. (10657892) in view of Lee (11335755). With regard to claim 5, Woo et al. disclose the first capacitor electrode (Cst11, Cst21) is formed of a same material as the gate electrode (G11, G12), but Woo et al. do not clearly disclose the second capacitor electrode is formed of a same material as the drain electrode. PNG media_image3.png 392 497 media_image3.png Greyscale However, Lee discloses the second capacitor electrode (referred to as “CAP2” by examiner’s annotation shown in fig. 3 below) of the capacitor (CAP) is formed of a same material as the drain electrode (160d). (for example, see column 11, lines 27 – 30, fig. 3). PNG media_image5.png 473 746 media_image5.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Woo et al.’s device to have the second capacitor electrode is formed of a same material as the drain electrode as taught by Lee in order to have the same process reducing a cost of manufacturing and enhance a stability operation of the semiconductor device, as is known to one of ordinary skill in the art. 8. Claims 6, 7 are rejected under 35 U.S.C. 103 as being unpatentable over Woo et al. (10657892) in view of Lee (11335755) and further in view of Sun (2005/0275352). With regard to claims 6, 7, Woo et al. and Lee do not clearly disclose the first capacitor electrode of the plurality of capacitors is connected to a first signal line connected to the gate electrode and the second capacitor electrode of the plurality of capacitors is connected to a second signal line connected to the source electrode wherein at least one of a connection of the first capacitor electrode and the first signal line and a connection of the second capacitor electrode and the second signal line is disconnected in a defective capacitor of the plurality of capacitors.

Therefore, the wire portion S1 inherently functioning as a source electrode; for example, see paragraph [0008]) wherein a connection (referred to as “16A1” by examiner’s annotation shown in fig. 7B below) of the first capacitor electrode (18A1) and the first signal line (SL1) is disconnected in a defective capacitor (for example, see paragraphs [0035], [0036]) of the plurality of capacitors (18, 16). PNG media_image6.png 472 567 media_image6.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Woo et al. and Lee’s device to have the first capacitor electrode of the plurality of capacitors is connected to a first signal line connected to the gate electrode and the second capacitor electrode of the plurality of capacitors is connected to a second signal line connected to the source electrode wherein at least one of a connection of the first capacitor electrode and the first signal line and a connection of the second capacitor electrode and the second signal line is disconnected in a defective capacitor of the plurality of capacitors as taught by Sun in order to enhance a stability operation of the semiconductor device when a capacitor for a pixel current is open-circuited or short-circuited, as is known to one of ordinary skill in the art. 9. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over Woo et al. (10657892) in view of Huang (11018169). With regard to claim 9, Woo et al. disclose two capacitors (Cst, Cse) are formed by overlapping one first capacitor electrode (Cst11) and two second capacitor electrodes (Cse11, Cse12). PNG media_image3.png 392 497 media_image3.png Greyscale Woo et al. do not clearly disclose a finger portion is formed in each of the two second capacitor electrodes to interlock with each other. However, Huang discloses a finger portion (referred to as “E1” by examiner’s annotation shown in fig. 1 below) is formed in each of the two second capacitor electrodes (130, 134) to interlock with each other. (for example, see fig. 1). PNG media_image7.png 516 649 media_image7.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Woo et al.’s device to have the second capacitor electrode is formed of a same material as the drain electrode as taught by Huang in order to enhance a high capacitance of the capacitor of the semiconductor device, as is known to one of ordinary skill in the art. 10. Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Sun (2005/0275352) in view of Woo et al. (10657892). With regard to claim 13, Sun does not clearly disclose the capacitors are disposed on a same plane in the at least one of the sub-pixels. However, Woo et al. disclose the plurality of capacitors (Cst, Cse) disposed in parallel on a same plane (a top surface plane of the layer 11, fig. 9 functions as a same plane) in the sub-pixel (PX as shown in fig. 9 below). PNG media_image3.png 392 497 media_image3.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Woo et al.’s device to have the capacitors are disposed on a same plane in the at least one of the sub-pixels as taught by Sun in order enhance a high capacitance of the capacitor of the semiconductor device and reducing a cost of manufacturing, as is known to one of ordinary skill in the art. 11. Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Sun (2005/0275352) in view of Huang (11018169). With regard to claim 16, Sun does not clearly disclose two capacitors of the plurality of capacitors are formed by overlapping one first capacitor electrode and two second capacitor electrodes, and a finger portion is formed in each of the two second capacitor electrodes to interlock with each other. However, Huang discloses two capacitors (capacitor 130a, 132a, 134a and capacitor 130b, 132b, 134b) of the plurality of capacitors are formed by overlapping one first capacitor electrode (134a) and two second capacitor electrodes (130a, 130b), and a finger portion (referred to as “E1” by examiner’s annotation shown in fig. 1 below) is formed in each of the two second capacitor electrodes to interlock with each other. (for example, see fig. 1). PNG media_image8.png 505 638 media_image8.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Woo et al.’s device to have the second capacitor electrode is formed of a same material as the drain electrode as taught by Huang in order to enhance a high capacitance of the capacitor of the semiconductor device for enhancing a stability operation of the semiconductor device, as is known to one of ordinary skill in the art.
