Office Action

§103 §112
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 . Information Disclosure Statement The German Office Action cited in IDS filed 18 October 2023 has not been considered as no English translation has been provided. Claim Interpretation Claim 1 lines 3-4 and 8-9 recite the limitations “A anode electrodes with A anode current collectors having a first side, a second side, a first end, and a second end” and “C cathode electrodes with C cathode current collectors having a first side, a second side, a first end, and a second end”, which are being interpreted as C cathode electrodes with C cathode current collectors having another first side, another second side, another first end, and another second end. 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 2-13 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. Claim 2 lines 1-2 recites the limitation “the electrode stack is inserted into the internal cavity through one of the first side and the second side of the housing” which renders the meaning of the claim indefinite because seemingly applicant is claiming a method of inserting the electrode stack when the claims are drawn towards a product. For examination purposes the aforementioned recitation has been interpreted as “wherein the electrode stack is configured to be inserted into the internal cavity through one of the first side and the second side of the housing” (i.e., a functional recitation which is not given patentable weight). Claims 3-13 are rejected as being dependent upon above rejected claim 2. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 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) 1-11 and 14-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Batson WO2018231605A1 in view of Kotik WO2017063880A1.

Claim(s) 12-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Batson WO2018231605A1 in view of Kotik WO2017063880A1 and further in view of Lee US20060024578A1. Regarding claim 12, modified Batson does not teach wherein the first tab positioning member includes: a planar conducting portion arranged along the first end of the housing, an external lead tab connected to the planar conducting portion, and a second planar conducting portion arranged along the first side of the housing, in contact with the A external tabs of the A anode electrodes, and including an end abutting the planar conducting portion. Lee teaches wherein the first tab positioning member (Lee, [0022], Fig. 2, connectors 17, support 20) includes: a planar conducting portion (Lee, [0022], annotated Fig. 2, planar conducting portion) arranged along the first end of the housing (Lee, annotated Fig. 2, case 15, first end), PNG media_image5.png 597 691 media_image5.png Greyscale an external lead tab (Lee, [0022], Fig. 2, terminal 32) connected to the planar conducting portion (Lee, annotated Fig. 2, planar conducting portion, terminal 32) and a second planar conducting portion (Lee, [0022], annotated Fig. 2, second planar conducting portion) arranged along the first side of the housing (Lee, annotated Fig. 2, case 15, first side), in contact with the A external tabs (Lee, [0022], Fig. 2, region 12a) of the A anode electrodes (Lee, [0022], Figs. 1-2, plate 12), and including an end abutting the planar conducting portion (Lee, annotated Fig. 2, planar conducting portion, second planar conducting portion). Therefore it would be obvious to the skilled artisan before the effective filing date of the claimed invention to add the first tab positioning member of Lee to modified Batson thereby improving durability (Lee, [0036]). Regarding claim 13, modified Batson does not teach wherein the second tab positioning member includes: a planar conducting portion arranged along the second end of the housing, an external lead tab connected to the planar conducting portion, and a second planar conducting portion arranged along the second side of the housing, in contact with the C external tabs of the C cathode electrodes and including an end abutting the planar conducting portion. Lee teaches wherein the second tab positioning member (Lee, [0022], Fig. 2, connectors 17, support 20) includes: PNG media_image6.png 568 678 media_image6.png Greyscale a planar conducting portion (Lee, [0022], annotated Fig. 2, planar conducting portion) arranged along the second end of the housing (Lee, annotated Fig. 2, case 15, second end), an external lead tab (Lee, [0022], Fig. 2, terminal 31) connected to the planar conducting portion (Lee, annotated Fig. 2, planar conducting portion, terminal 31) and a second planar conducting portion (Lee, [0022], annotated Fig. 2, second planar conducting portion) arranged along the side of the housing (Lee, annotated Fig. 2, case 15, side), in contact with the C external tabs (Lee, [0022], Fig. 2, region 11a) of the C cathode electrodes (Lee, [0022], Figs. 1-2, plate 12) and including an end abutting the planar conducting portion (Lee, annotated Fig. 2, planar conducting portion, second planar conducting portion). Therefore it would be obvious to the skilled artisan before the effective filing date of the claimed invention to add the second tab positioning member of Lee to modified Batson thereby improving durability (Lee, [0036]). Response to Arguments Applicant’s arguments, see pp. 9-10, filed 28 May 2026, with respect to the 112 rejection of claims 1 and 14-18 have been fully considered and are persuasive. The 112 rejection of claims 1-18 has been withdrawn as it has been overcome by applicant’s amendment. Applicant’s arguments with respect to the 112 rejection of claims 2-13 have been considered but are not persuasive and the rejection and interpretation are set forth above. Applicant’s arguments with respect to claim(s) 1 and 14 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Kim US20120015226A1 (discloses tabs disposed along the sides and the ends), Que US20210110979A1 (discloses tab s disposed along the sides and the ends), Campbell US20230103136A1 (discloses an electrochemical device comprising tabs disposed on either sides or ends). 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.
