DETAILED ACTION
Notice of Pre-AIA or AIA Status
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
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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 01/07/2026 has been entered.
Response to Arguments
Applicant’s amendments and the accompanying arguments with respect to the rejection(s) of claim(s) under 35 U.S.C. 112 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Kim et al. (US 2018/0343753).
Applicant argued the previously applied references, including Kim et al. (US 2018/0343753), do not teach a plurality of anchor portions in a region overlapping the wiring lines and in a region not overlapping the wiring lines because while Kim teaches anchor portions, OPN in Figure 3, overlapping the wiring lines Dc, Kim does not teach openings OPN in a region not overlapping the wiring lines.
However, Kim further teaches “The display device may include a plurality of lines in the bent region BA, and the openings OPN may be provided between the plurality of lines,” paragraph 136. By this description, and what is clearly suggested by Figure 3, Kim teaches anchor portions OPN in a region overlapping the wiring lines and in a region not overlapping the wiring lines.
For at least these reasons, Kim anticipates all of the limitations as claimed.

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.
Claim 8 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2018/0343753) in view of Jin et al. (US 2019/0140202).
In reference to claim 8, Kim does not disclose each of the plurality of recessed portions has a depth extending through the second resin layer and the first resin layer.
Jin et al. (US 2019/0140202) discloses a display device including teaching a plurality of recessed portions, 14 in Figure 8D, have a depth extending through a second resin layer 125, paragraph 179, and the thin film transistor level 18, paragraphs 192 and 193.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the depth of the recessed portions of Kim to extend through the thin film transistor level resulting in each of the plurality of recessed portions has a depth extending through the second resin layer and the first resin layer. One would have been motivated to do so in order to increase the contact area between the laminated films in order to prevent peeling or separating between the layers, paragraph 194.
Claim 12 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2018/0343753) in view of Jeong et al. (US 2019/0355799).
In reference to claim 12, Kim discloses a plurality of thin film transistors each including a gate electrode GE, and a source electrode SE and a drain electrode DE that are provided at a layer different from a layer of the gate electrode, and
a first flattening layer INS1 covering the plurality of thin film transistors and including a resin material, paragraphs 80 and 81.
Kim does not disclose an intermediate electrode provided in an island shape on the first flattening layer and configured to be electrically connected to the drain electrode through a contact hole formed in the first flattening layer,
a second flattening layer covering the intermediate electrode, provided on the first flattening layer, and including a resin material, and
an anode electrode or a cathode electrode provided in an island shape on the second flattening layer,
the plurality of first lead-out wiring lines and the plurality of second lead-out wiring lines are provided at a layer identical to a layer of a plurality of the source electrodes and a plurality of the drain electrode, or
the plurality of relay wiring lines are provided at a layer identical to a layer of the intermediate electrode.
Jeong et al. (US 2019/0355799) discloses a display device including teaching an intermediate electrode, 182 in Figure 16, provided in an island shape on the first flattening layer 165 and configured to be electrically connected to the drain electrode 133 through a contact hole formed in the first flattening layer,
a second flattening layer, 220 in Figure 20, covering the intermediate electrode 182, provided on the first flattening layer 165, and including a resin material, paragraph 107, and
an anode electrode or a cathode electrode 250 provided in an island shape on the second flattening layer, paragraph 110,
the plurality of first lead-out wiring lines 134a and the plurality of second lead-out wiring lines 134b are provided at a layer identical to a layer of a plurality of the source electrodes 132 and a plurality of the drain electrode 133, paragraphs 102 and 58, and
the plurality of relay wiring lines 185 are provided at a layer identical to a layer of the intermediate electrode 182, paragraph 82.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to combine Kim and Jeong such that an intermediate electrode is provided in an island shape on the first flattening layer and configured to be electrically connected to the drain electrode through a contact hole formed in the first flattening layer,
a second flattening layer covering the intermediate electrode, provided on the first flattening layer, and including a resin material, and
an anode electrode or a cathode electrode provided in an island shape on the second flattening layer,
the plurality of first lead-out wiring lines and the plurality of second lead-out wiring lines are provided at a layer identical to a layer of a plurality of the source electrodes and a plurality of the drain electrode, and
the plurality of relay wiring lines are provided at a layer identical to a layer of the intermediate electrode.
To do so would have merely been to apply a known technique to improve similar devices in the same way, KSR International Co. v. Teleflex Inc. (KSR), 550 U.S. 398, 82 USPQ2d 1385 (2007), MPEP 2143 I. C. In this case applying the technique of anchored resin portions in the bending area as taught by Kim to the display with the wiring configured as taught by Jeong.
Claim 14 is rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2018/0343753) in view of Zhai et al. (US 2020/0028114).
In reference to claim 14, Kim does not disclose the third resin layer includes ultraviolet-curing resin.
Zhai et al. (US 2020/0028114) discloses a display device including teaching a resin layer, 22 in Figure 15, includes ultraviolet-curing resin, paragraph 77. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention for the third resin layer to include ultraviolet-curing resin. To do so would have merely been a simple substitution of one known element for another to obtain predictable results; KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 82 USPQ2d 1385, (2007), MPEP 2143 I. B. In this case substituting one resin for another.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Saitoh et al. (US 2020/0150725), Um et al. (US 2019/0035872), Lim et al. (KR 20160066369 A), Choi et al. (US 2020/0105168), and Zhai et al. (US 2020/0028114) disclose related devices.
