Office Action

§103
Detailed Action 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 2. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 11/21/2026 has been entered. Claim Rejections - 35 USC § 103 3. 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 of this title, 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. 4. Claims 1 and 6-7 are rejected under 35 U.S.C. 103 as unpatentable over WU (US 20120120364 A1; Figs. 6 and 4) in view of YU (US 20130082942 A1) and further in view of PAOLINI (US 20160062206 A1). Regarding claim 1, WU (e.g., Fig. 6 and Fig. 4) discloses a touch display device comprising: a driving substrate (driving substrate 101; [0018]); a display medium layer (electrophoretic display layer 105; [0019]) disposed on the driving substrate (driving substrate 101); a touch panel (touch panel 119; [0026]) having a bonding area; a flexible circuit board (flexible circuit board 109; [0019]) bonded to the bonding area of the touch panel (touch panel 119); a water-blocking adhesive layer (sealant layer 113b, water and moisture resist material; [0021]-[0022] and [0028]-[0029]) directly connected between a bottom surface of the flexible circuit board (flexible circuit board 109) outside the touch panel (touch panel 119) and a top surface of the driving substrate (driving substrate 101); and a sealant layer (sealant layer 113a; [0021]-[0022] and [0028]-[0029]) disposed on the driving substrate (driving substrate 101) and sealing an edge of the display medium layer (electrophoretic display layer 105), and an edge of the touch panel (touch panel 109), wherein in a cross-sectional view, the sealant layer (sealant layer 113a) is located between the water-blocking adhesive layer (sealant layer 113b) and the edge of the display medium layer (display medium layer 105); in the cross-sectional view at the bonding area of the touch panel (touch panel 119), wherein the sealant layer (sealant layer 113a) extends to cover the edge of the display medium layer (display layer 105) and the edge of the touch panel (touch panel 119). WU does not expressly disclose an electrode substrate disposed on the display medium layer. However, WU (Figs. 4 and 6) discloses an electrophoretic display device. It is well known that the electrophoretic display comprising an electrode substrate disposed on the display medium layer. In addition, WU does not disclose the flexible circuit board extending to outside of the touch panel. However, YU (e.g., Fig. 11-13 and 3-8) discloses a touch electrophoretic display device similar to that similar to that disclosed by WU, comprising: a driving substrate (driving substrate 212; [0029]-[0032]); a display medium layer (display medium layer 222; [0029]-[0032]) disposed on the driving substrate; an electrode substrate (electrode layer 224; [0029]-[0032]) disposed on the display medium layer; a touch panel (touch panel 228; [0029]-[0032]) disposed on the electrode substrate and having a bonding area; a flexible circuit board (flexible circuit board 312; [0044]) bonded to the bonding area of the touch panel and extending to outside of the touch panel (e.g., Fig. 11-13); and a sealant layer (sealant layer comprising sealant layer 240; [0031]) disposed on the driving substrate (driving substrate 212) and sealing an edge of the display medium layer (display medium layer 222), an edge of the electrode substrate (electrode layer 224), and an edge of the touch panel (touch panel 228). Therefore, it would have been obvious to one skilled in the art at the effective filing date of the claimed invention to incorporate the teaching from YU to the electrophoretic display device of WU. The combination/motivation would be to provide a water-resist sealing structure to package a touch display. YU (e.g., Fig. 11-13 and 3-8) also discloses wherein the edge of the display medium layer (display medium layer 222) is indented by a distance relative to the edge of the electrode substrate (electrode substrate 224) to form a space (space S), and a sealant layer fills the space (space S).

WU does not expressly disclose an electrode substrate disposed on the display medium layer. In addition, WU does not disclose wherein the flexible circuit board extends outside the touch panel. However, WU (Figs. 4 and 6) discloses an electrophoretic display device. It is well known that the electrophoretic display comprising an electrode substrate disposed on the display medium layer. As a reference, YU (e.g., Fig. 11-13 and 3-8) discloses a touch electrophoretic display device and a manufacturing method of a touch display device comprising similar to that similar to that disclosed by WU, comprising: forming a display medium layer (display medium layer 222; [0029]-[0032]) and an electrode substrate (electrode layer 224; [0029]-[0032]) on a driving substrate (driving substrate 212; [0029]-[0032]) in sequence; bonding a flexible circuit board (flexible circuit board 312; [0044]) to a bonding area of a touch panel (touch panel 228; [0029]-[0032]), wherein the flexible circuit board (flexible circuit board 312) extends outside the touch panel (touch panel 228); bonding the touch panel (touch panel 228) to the electrode substrate (electrode layer 224); and filling a sealant layer (sealant layer comprising sealant layer 240; [0031]) on the driving substrate (driving substrate 212) to seal an edge of the display medium layer (display medium layer 222), an edge of the electrode substrate (electrode layer 224), and an edge of the touch panel (touch panel 228); and a sealant layer (sealant layer comprising sealant layer 240; [0031]) disposed on the driving substrate (driving substrate 212) and sealing an edge of the display medium layer (display medium layer 222), an edge of the electrode substrate (electrode layer 224), and an edge of the touch panel (touch panel 228). Therefore, it would have been obvious to one skilled in the art at the effective filing date of the claimed invention to incorporate the teaching from YU to the electrophoretic display device of WU. The combination/motivation would be to provide a water-resist sealing structure to package a touch display. YU (e.g., Fig. 11-13 and 3-8) also discloses wherein the edge of the display medium layer (display medium layer 222) is indented by a distance relative to the edge of the electrode substrate (electrode substrate 224) to form a space (space S), and a sealant layer fills the space (space S).
