Claim Rejections - 35 USC § 103 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over YUAN as applied above in view of US-9911799-B2 by Cho (hereinafter CHO). YUAN discloses the display device of claim 9. YUAN does not disclose wherein a rim of the substrate, which faces a respective data line is generally parallel for portions of its length to the respective data line. CHO teaches wherein a rim of the substrate, which faces a respective data line is generally parallel for portions of its length to the respective data line (Fig. 2/DL are parallel to left and right edges of 10a). It is well-known in the art to arrange the pixels (Fig. 2/EP, col. 7 line 31) in an orthogonal array parallel to edges of the display panel. Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to incorporate the parallel data lines of CHO into the display panel of YUAN to get the best display effect. Claims 13 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over YUAN as applied above. Claim 13. YUAN discloses the display device of claim 1. YUAN does not disclose wherein the conductive oxide layer is a transparent oxide semiconductor layer. YUAN does teach the use of ZnO (which is transparent), among others, as a transparent semiconducting layer (Fig. 2/11, p.9, para. 9, lines 1-2). It is a matter of simple substitution to provide a semiconducting transparent oxide layer for a conducting one, to obtain the predictable result of a charge-transporting material with transparency (see MPEP § 2141 (III)). Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to incorporate the transparent semiconductor of Fig. 2/11 into the substrate 2 of Fig. 2 to combine transparency and electrical conduction. Claim 21. YUAN discloses the display device of claim 19. YUAN does not disclose wherein each substrate is comprised of a semiconductor oxide layer. YUAN does not disclose wherein each substrate is comprised of a semiconductor oxide layer. YUAN does teach the use of ZnO (which is transparent), among others, as a transparent semiconducting layer (Fig. 2/11, p.9, para. 9, lines 1-2). It is a matter of simple substitution to provide a semiconducting transparent oxide layer for a conducting one, to obtain the predictable result of a charge-transporting material with transparency (see MPEP § 2141 (III)). Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to incorporate the transparent semiconductor of Fig. 2/11 into the substrate 2 of Fig. 2 to combine transparency and electrical conduction. Claim 23 is rejected under 35 U.S.C. 103 as being unpatentable over YUAN as applied above in view of US-8748889-B2 by Sasaki (hereinafter SASAKI). YUAN discloses the display device of claim 19. YUAN does not disclose wherein the base layer is transparent polarizing plate. SASAKI teaches wherein the base layer is transparent polarizing plate (col. 19, lines 50- 51). There is a motivation to provide an anti-reflection property to the device so as to reduce glare (col. 21, lines 25-26). Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the instant application to incorporate the polarizing substrate of SASAKI into the display device of YUAN to improve the display effect. Response to Arguments Applicant's arguments filed 09/11/25 have been fully considered but they are not persuasive. Applicant’s only arguments are as follows: The Office Action cites capacitor electrode (2 ) of Yuan (CN ‘686) as allegedly a conductive oxide. However, Yuan does not teach the electrode (2) is transparent. Examiner’s responses are as follows: Yuan explicitly discloses the material of (first) capacitor electrode (2) may be a metal oxide of the like, the material can be transparent material (see at least see at least p. 7, para. 2 of the attached translated description). Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
