Office Action

§102 §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 Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Claims 4 and 9 are interpreted to invoke 112f because the claims meet the following three prong test: Prong A: Yes, “means” is used as a generic placeholder for performing the claimed function of “switching.” Prong B: Yes, “switching means” is modified by the functional language “configured to switch between a first state in which the first input/output line is electrically connected to the positive terminal of the secondary battery pack and a second state in which the first input/output line is electrically connected to the negative terminal of the second battery of the secondary battery pack; a second input/output line electrically connected to the bipolar terminal of the third battery of the secondary battery pack” Prong C: Yes, “switching means” is not modified by sufficient structure to perform the claimed function. Since all three prongs are met the recitation of “switching means” in Claims 4 and 9, invoke 112f. As identified in the specification, the structure that corresponds to the “switching means” is interpreted to correspond to the structure of a bipolar transistor, see instant-spec. [0029]. 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. Claim(s) 1 is/are rejected under 35 U.S.C. 103 as being unpatentable over Mizusawa (JP-2016171075-A as provided in the IDS dated 10/06/2022 with citations from the provided translation) optionally in view of Sasaki et al. (US-20190157725-A1). Regarding Claim 1, Mizusawa discloses: A secondary battery pack comprising: a first battery and a second battery each of which includes a positive terminal and a negative terminal (see annotated Fig. 9a below); a third battery including a positive terminal, a negative terminal, and a bipolar terminal (see annoted Fig. 9a below); a first connector configured to electrically connect the negative terminal of the first battery and the positive terminal of the third battery (see annotated Fig. 9a below); and a second connector configured to electrically connect the positive terminal of the second battery and the negative terminal of the third battery (see annotated Fig. 9a below), where the third battery includes the following elements, with n being an integer equal to or greater than zero: (n+ 1) positive electrode and (n+1) negative electrodes alternately arranged; (2n+1) bipolar electrodes individually located in spaces between the positive electrodes and the negative electrodes neighboring each other (1st electrode of (n + 1) sheets laminated stacked alternately, and the 2nd electrode of (n + 1) sheets A total of (2n + 1) third electrodes positioned between adjacent first and second electrodes, see [0008] and annoted Fig 9 below. Wherein, the first electrode and the second electrode each are one of the negative or positive, and the third electrode is a bipolar electrode, see [0008] and [0013]); an electrolyte (electrolyte, see [0008]); a positive-electrode connection member configured to electrically connect the positive terminal of the third battery and the (n+1) positive electrodes (see annotated Fig 9a below); a negative-electrode connection member configured to electrically connect the negative terminal and the (n+1) negative electrodes (see annotated Fig. 9a below); and a bipolar-electrode connection member configured to electrically connect the bipolar terminal and each of the (2n+1) bipolar electrodes (see annotated Fig. 9a below) Mizusawa does not necessarily teach: wherein the (n+1) positive electrodes, the (n+1) negative electrodes, and the (2n+1) bipolar electrodes are arranged with respect to each other in a V-shaped, U-shaped, or zigzag form. However, Mizusawa teaches a suitable embodiment in which the anode, cathode, and biode electrodes are in a wound configuration, see [0038] and Fig. 6A. Fig. 6 A shows that at least a portion of the electrodes are in a U-shape with respect to each other. Therefore, absent a showing of persuasive secondary considerations, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to disposes in a wound configuration such that the electrodes have a least a portion are shaped in a U with respect to each other because Mizusawa teaches this is a suitable configuration for the batteries of the invention. Assuming arguendo that Mizusawa does not anticipate the following limitation: wherein the (n+1) positive electrodes, the (n+1) negative electrodes, and the (2n+1) bipolar electrodes are arranged with respect to each other in a V-shaped, U-shaped, or zigzag form (). To solve the same problem of designing a battery that can suitably use bipolar electrodes (see Abstract and Pg14/C13/L29-32), Sasaki teaches disposing the electrodes in a zigzag honeycomb configuration to lessen heat generated per unit volume and can achieve higher currents, see Pg13/C11/L21-26 and Fig. 4. Absent a showing of persuasive secondary considerations, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have disposed the electrodes of Mizusawa into a zigzag honeycomb structure as taught by Saski to reduce heat generated per unit volume to achieve higher currents.

(US-20190157725-A1) as applied to Claim 1 above and in further view of White et al. (US-20160020443-A1). Regarding Claim 3, Mizusawa teaches the DC batteries can be charged/discharged so therefore are secondary batteries, see [0042]. However, Mizusawa is silent toward the structure of the DC batteries (i.e., the indicated first and second batteries shown in annotated Fig. 9a above) and therefore, does not teach: wherein at least one of the first battery and the second battery includes a plurality of secondary battery cells connected in series or in parallel. To solve the same problem designing battery packs (see Abstract), White teach it is conventional and successful to have DC batteries that comprise a plurality of cells that are connected in parallel, see [0438]. Consequently, one of ordinary skill in the art before the effect filling date of the claimed invention would have had a reasonable expectation of success in preparing DC batteries of Mizusawa with a plurality of cells connected in parallel as taught by White. Applying a known technique to a known device (method or product) ready for improvement to yield predictable results is likely to be obvious. See KSR International Co. v. Teleflex Inc., 550 U.S. __,__, 82 USPQ2d 1385, 1395 – 97 (2007) (see MPEP § 2143, D.). Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Mizusawa (JP-2016171075-A as provided in the IDS dated 10/06/2022 with citations from the provided translation) optionally in view of Sasaki et al. (US-20190157725-A1) as applied to Claim 1 above and in further view of Tatebayashi et al. (US-20100237829-A1). Regarding Claim 4, Mizusawa with the following modification in view of Tatebayashi teaches: A secondary battery module including the secondary battery pack according to-claim 1 (see annotated Fig. 9a-9b below), the secondary battery module comprising: a first input/output line (see annotated Fig. 9a-9b below); a switching means (switch circuit 3G which includes a bipolar transistor, see [0019], [0042], and Fig. 9a-9b) configured to switch between a first state in which the first input/output line is electrically connected to the positive terminal of the secondary battery pack and a second state in which the first input/output line is electrically connected to the negative terminal of the second battery of the secondary battery pack (see Fig. 9a-9b); a second input/output line electrically connected to the bipolar terminal of the third battery of the secondary battery pack (see annotated Fig. 9a-9b below); Mizusawa is silent toward use of a controller in the switching circuit 3G and, therefore, does not teach: and a controller configured to control the switching means. To solve the same problem of designing a charge/discharge switch for a battery (see [0028]), Tatebayashi teaches using a controller to monitor and control a charge/discharge switch, see [0028]. Absent a showing of persuasive secondary considerations, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have used a controller as taught by Tatebayashi in the switching circuit of Mizusawa in order to monitor and control the switch circuit. PNG media_image3.png 816 1439 media_image3.png Greyscale Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Mizusawa (JP-2016171075-A as provided in the IDS dated 10/06/2022 with citations from the provided translation) in view of White et al. (US-20160020443-A1) optionally in view of Sasaki et al. (US-20190157725-A1) as applied to Claim 1 and 3 above and in further view of Tatebayashi et al. (US-20100237829-A1). Regarding Claim 9, modified Mizusawa with the following additional modification in view of Tatebayashi teaches: A secondary battery module including the secondary battery pack according to claim 3 (see annotated Fig. 9a-9b above), the secondary battery module comprising: a first input/output line (see annotated Fig. 9a-9b above); a switching means (switch circuit 3G which includes a bipolar transistor, see [0019], [0042], and Fig. 9a-9b) configured to switch between a first state in which the first input/output line is electrically connected to the positive terminal of the secondary battery pack and a second state in which the first input/output line is electrically connected to the negative terminal of the second battery of the secondary battery pack (see Fig. 9a-9b); a second input/output line electrically connected to the bipolar terminal of the third battery of the secondary battery pack (see annotated Fig. 9a-9b above); Mizusawa is silent toward use of a controller in the switching circuit 3G and, therefore, does not teach: and a controller configured to control the switching means. To solve the same problem of designing a charge/discharge switch for a battery (see [0028]), Tatebayashi teaches using a controller to monitor and control a charge/discharge switch, see [0028]. Absent a showing of persuasive secondary considerations, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have used a controller as taught by Tatebayashi in the switching circuit of Mizusawa in order to monitor and control the switch circuit. Response to Arguments Applicant’s arguments, see pages 13-14, filed 04/29/2026, with respect to the rejection(s) of claim(s) 1, 3-4, 9 and 16 under 35 USC §§ 102 and 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. In the interview summary dated 12/17/2025, it was the Examiner’s position that the proposed and now entered claim amendments would overcome the §102 rejection of record and that a §103 rejection could possibly be formulated. Upon further consideration, a §103 rejection using an alternative interpretation of Mizusawa (JP-2016171075-A) is given above for Claims 1, 3-4, 9 and 16 and optionally in view of newly applied art Sasaki et al. (US-20190157725-A1). 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.
