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 5 is rejected under 35 U.S.C. 103 as being unpatentable over Takahashi et al. (US 2009/0133734), as applied to claim 2 above, in view of Jinushi et al. (US 2014/0311543). Regarding claim 5, Takahashi discloses all of the claim limitations as set forth above. Takahashi does not explicitly disclose that the supporter is provided with a plurality of through holes penetrating through the supporter along a wall thickness direction of the supporter. Jinushi discloses a thermoelectric device in Figure 1 comprising a supporter (13) that is provided with a plurality of through holes (openings for lead wires 149) penetrating through the supporter along a wall thickness direction of the supporter in order to facilitate connection to lead terminals (149) and current extraction from the device ([50]). It would have been obvious to one having ordinary skill in the art at the time the invention was filed to add a plurality of through holes penetrating through the supporter along a wall thickness direction of the supporter in the device of Takahashi, as taught by Jinushi, in order to facilitate connection to lead terminals and current extraction from the device (Jinushi, [50]). Claims 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Takahashi et al. (US 2009/0133734), as applied to claim 1 above, in view of Chintala et al. (US 2020/0388739).
