Office Action

§103
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 . Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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(s) 1-10 and 14-20 are rejected under 35 U.S.C. 103 as being unpatentable over Song et al. (US 20200264660) modified by Chun et al. (US 20210201712 A1), Akutagawa et al. (US 20220056228) and further in view of Cho (US 20140140037 A1). Re claim 1: Song discloses an electronic device (100 in fig 3) comprising: a first housing (first frame 101 in fig 3); a second housing (second frame 102 in fig 3) connected to the first housing, a relative position of the second housing being changeable with respect to the first housing, and a display comprising a display panel (display unit 151 in fig 3) comprising a deformation area (third region 151c in fig 12) deformed as the relative position between the first housing (101) and the second housing (102) is changed (see paragraph 103). Song fails to disclose the display comprising a window layer and the display panel disposed under the window layer; a substrate layer comprising a pattern including a plurality of protrusions, the substrate layer being disposed above the window layer and exposed to an outside of the electronic device; and an adhesive layer disposed between the window layer and the substrate layer, at least a portion of the adhesive layer being disposed between the plurality of protrusions of the substrate layer. Chun discloses a display (100 in fig 2) comprising: a window layer (420 in fig 4), and a display panel (PNL in fig 6) disposed under the window layer, the display panel comprising a deformation area (folding area A1 in fig 4); a substrate layer (430 in fig 4) comprising a pattern including a plurality of protrusions (432 in fig 4), the substrate layer being disposed above the window layer and exposed to an outside of the electronic device; and an adhesive layer (440 in fig 4) disposed between the window layer and the substrate layer, at least a portion of the adhesive layer being disposed between the plurality of protrusions of the substrate layer. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to provide the display with a window layer disposed over a display panel, a substrate layer being disposed above the window layer and exposed to an outside of the electronic device, and an adhesive layer disposed between the window layer and the substrate layer, as shown in the device of Chun, in order to shield the display panel from scratches, impacts, dust, and environmental hazards for extending the display panel’s lifespan. Moreover, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to provide the substrate layer with a pattern including a plurality of protrusions in order to enhance attachment strength with the adhesive layer. Song in view of Chun fails to disclose that the at least a portion of the adhesive layer comprising a refractive index adjustment member mixed therein in order to reduce a refractive index difference with the substrate layer. Akutagawa discloses mixing in a refractive index adjustment member in order to reduce a refractive index difference between layers (see paragraph 459). It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to provide the at least a portion of the adhesive layer with a refractive index adjustment member mixed therein, as shown in the device of Akutagawa, since such a modification would allow for adjustment of the layer’s refractive index and may inhibit interference fringes while minimizing the refractive index difference between layers (Akutagawa: see paragraph 459). Song in view of Chun and Akutagawa fails to disclose that the plurality of protrusions are formed at a nanometer scale. Cho discloses a cover window (21 in fig 2) provided above a display panel, wherein the cover window comprising a pattern (212 in fig 2) including a plurality of protrusions, wherein the plurality of protrusions are formed at a nanometer scale (see paragraph 38).
