§102 §103 §112
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 . Status of Application Claims 1-20 are currently pending. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1,4 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding the limitation “along the first direction, a distance D1 between the first terminal through-hole in the first group of through-holes and the second terminal through-hole in a third group of through-holes adjacent to the first group of through-holes is greater than a distance D3 between two adjacent third groups of through-holes” in claim 1, it is unclear whether the distance D1 pertains to: a distance between the first terminal through-hole of the first group and the second terminal through-hole of third group being adjacent to one another, or a distance between the first terminal through-hole of the first group and the second terminal through-hole of the third group being diagonal to one another For examination purposes and in light of the [PG Pub 0165] and Fig 18, interpretation (1) has been considered. Regarding the limitation “a distance between the second terminal through-hole in the second group of through-holes and the first terminal through-hole in a third group of through-holes adjacent to the second group of through-holes is D2” in claim 4, it is unclear whether the distance D2 pertains to: a distance between the second terminal through-hole of the second group and the first terminal through-hole of a third group being adjacent to one another, or a distance between the second terminal through-hole of the second group and the first terminal through-hole of a third group being diagonal to one another For examination purposes and in light of the [PG Pub 0154] and Fig 11, interpretation (1) has been considered. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the D1, D2, D3 must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.

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) 3,4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Toru (JP2012212605, IDS cited 01/11/2024, translation attached). Regarding claim 3, Toru discloses the battery module according to claim 1. However, Toru does not disclose wherein a difference between D1 and D3 is greater than 6 mm. Examiner notes that the change in form or shape, without any new or unexpected results, is an obvious engineering design. See In re Dailey, 149 USPQ 47 (CCPA 1966) (see MPEP § 2144.04). Therefore, it would have been obvious for a person having ordinary skill in the art before the effective filing date to have modified the battery module of Toru to include a D1 and D3 difference greater than 6mm as a change in form or shape that is an obvious design based on the size of the battery module. Regarding claim 4, Toru discloses the battery module according to claim 1, wherein a distance between the second terminal through-hole in the second group of through-holes and the first terminal through-hole in a third group of through-holes adjacent to the second group of through-holes is D2 (see annotated Fig below). However, Toru does not explicitly disclose wherein D2 is less than D3. Examiner notes that the change in size and proportion, without any new or unexpected results, is an obvious engineering design. See In re Dailey, 149 USPQ 47 (CCPA 1966) (see MPEP § 2144.04, IV). Therefore, it would have been obvious for a person having ordinary skill in the art before the effective filing date to have modified the D2 and D3 such that D2 is less than D3, as a change size and proportion that is an obvious design based on the size of the battery module.
