Office Action

§103
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 . 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. 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. Claim(s) 1-10, 12, 13, 17-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over CHA et al. (US 2022/0182476) in view of SEO et al. (US 2018/0049329). Regarding claim 1 CHA discloses: A display panel comprising: at least three middle frames (e.g. 401, 402 FIG.8), every two adjacent said middle frames being rotatably connected (e.g. indicated FIG.10); and at least two hinges (e.g. 500 FIG.8), each of said hinges being connected to two adjacent said middle frames (e.g. indicated FIG.8); wherein torques of any two adjacent hinges are different (e.g. via duplicate 530 shown FIG.8/FIG.12, via angular difference shown FIG.11); wherein said hinges comprises a first hinge and a second hinge (e.g. shown FIG.9), each of the first hinge and the second hinge comprises one or more positioners (e.g. gearing teeth shown FIG.13) CHA does not explicitly disclose: and one or more elastic elements, and a number of said positioners in the second hinge is greater than a number of said positioners in the first hinge, and a number of said elastic elements in the second hinge is greater than a number of said elastic elements in the first hinge, wherein a torque of the first hinge is less than a torque of the second hinge SEO teaches: one or more elastic elements (e.g. middle of 204 FIG.9, middle of 1004 FIG.61), and a number of said positioners in the second hinge (e.g. ends of 204 FIG.10) is greater than a number of said positioners in the first hinge (e.g. ends of 1004 FIG.61), and a number of said elastic elements in the second hinge (e.g. middle of 204 FIG.9) is greater than a number of said elastic elements in the first hinge (e.g. middle of 1004 FIG.61), wherein a torque of the first hinge is less than a torque of the second hinge (e.g. the hinges of FIG.61 has fewer force units than the hinge of FIG.9).

Response to Arguments Applicant’s arguments with respect to the amended claim(s) have been considered but are moot because the new ground of rejection does not rely on any combination of references applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Furthermore the rejection above addressed all remaining arguments and so will not be repeated here. 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. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
