Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-20-02-aia AIA This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. 07-21-aia AIA Claim s 2-10, 14-17 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Takayuki (JP 7046244) .

With respect to claims 2-4: Takayuki discloses in [0036] adhesive. Also, in [0018] Takayuki discloses attaching support plate 22 to the surface of display module 20. It would have been obvious to a person having ordinary skill in the art at the time the invention was effectively filed to provide the display device of Takayuki with an adhesive layer, which has the same thickness as the first sub-wing plate in a direction perpendicular to a plane of the display module or a width less than that of the first sub-wing plate in the first direction, between the folding part and the first sub-wing plate by providing an adhesive layer to attach the support layer to the display module. The rationale is as follows: one of ordinary skill in the art at the time the invention was effectively filed would have been motivated to provide a display device with an adhesive layer which has the same thickness as the first sub-wing plate in a direction perpendicular to a plane of the display module or a width less than that of the first sub-wing plate in the first direction, between the folding part and the first sub-wing plate, which is well within the purview of a skilled artisan and absent an unobvious result, so as to attach support layer to display module via an adhesive layer to effectively, economically and securely fast fasten the two layers together. As per claim 5 Takayuki discloses: The display device of claim 2, further comprising a second-1 adhesive layer between the first wing plate 31A and the first sub-wing plate 27A { [0040] As shown in FIGS. 4C to 6, the base end portion of the first hinge-side locking piece 31A is fixed to the back surface 27Ad of the first support plate 27A with, for example, two screws 34.
