§102 §103 §112
CTNF 18/472,319 CTNF 89163 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia 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 § 112 07-30-02 AIA 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. 07-34-01 Claim 20 is rejected under 35 U.S.C. 112, second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which applicant regards as the invention. In claim 20, the limitation “the insulative tape” lacks antecedent basis. Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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 07-20-aia AIA 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 of this title, 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. 07-15 AIA 1. Claim s 1-20 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by, or in the alternative, are rejected under 35 U.S.C. 103 as being obvious over Sasakawa et al. (US20200091560) . 2. Regarding claims 1-20, Sasakawa teaches a prismatic battery (see Figure 2) comprising: a first electrode stack having a first anode, a first cathode and a first separator disposed between the first anode and the first cathode; a second electrode stack having a second anode, a second cathode and a second separator disposed between the second anode and the second cathode (As shown in FIG. 3 and the like, each of the electrode groups 5A and 5B includes a negative electrode 15, a separator 16, and a positive electrode 17. The separator 16 is interposed between the negative electrode 15 and the positive electrode 17, and electrically insulates the negative electrode 15 from the positive electrode 17 [0031]); a thermal barrier disposed between the first and second electrode stack (In the sheet member, the insulating layer is made of a material [0021]), wherein the first electrode stack, the thermal barrier and the second electrode stack form a first stack assembly (the sheet member 7 serves as a partition wall for isolating the electrode groups 5A and 5B, and the two electrode groups 5A and 5B that are adjacent to each other are objects to be isolated by the sheet member 7 [0030]); and a housing containing an electrolyte (The electrode groups 5A and 5B, the sheet member 7, and the electrolyte are housed inside the container members 3A and 3B [0027]), wherein the first stack assembly is disposed within an interior of the housing and submerged in the electrolyte (The electrolyte is held (impregnated) in each of the electrode groups 5A and 5B [0027]). 3. Sasakawa teaches comprising a thermally insulative tape wrapped around the first stack assembly wherein the insulative tape has a first and second surface wherein one of the first and second surfaces has an adhesive disposed thereon for adhering the thermally insulative tape to the first stack assembly (the adhesive layer (66, 67) [0075], adhesive tape 74 [0137], The protective sheet 88 is formed of rubber or resin [0140], [0146], [An insulating plate (not shown) [0138]). 4. Sasakawa teaches comprising a first tab protruding from the first anode and a second tab protruding from the second anode wherein the first and second tab are made of copper and a third tab protruding from the first cathode and a fourth tab protruding from the second cathode wherein the third and fourth tab are made of aluminum (the negative electrode current collecting tab 33…the positive electrode current collecting tab 37 [0032]; The negative electrode current collector is a metal body, and the metal body contains at least one metal selected from the group consisting of aluminum, copper [0093]; The positive electrode current collector is a metal body containing the same metal as the metal forming the negative electrode current collector [0104]) 5. Sasakawa teaches prismatic battery (Figure 2) comprising: a first electrode stack having a first anode, a first cathode and a first separator disposed between the first anode and the first cathode; a second electrode stack having a second anode, a second cathode and a second separator disposed between the second anode and the second cathode ( (As shown in FIG. 3 and the like, each of the electrode groups 5A and 5B includes a negative electrode 15, a separator 16, and a positive electrode 17. The separator 16 is interposed between the negative electrode 15 and the positive electrode 17, and electrically insulates the negative electrode 15 from the positive electrode 17 [0031]); a thermal barrier disposed between the first and second electrode stack (In the sheet member, the insulating layer is made of a material [0021]) , wherein the first electrode stack, the thermal barrier and the second electrode stack form a first stack assembly (the sheet member 7 serves as a partition wall for isolating the electrode groups 5A and 5B, and the two electrode groups 5A and 5B that are adjacent to each other are objects to be isolated by the sheet member 7 [0030]) ; a first thermal insulative sheet disposed on a first side of the first stack assembly (an insulating layer (first insulating layer) 26 [0035], Figures 2 and 8) ; a second thermal insulative sheet disposed on a second side of the first stack assembly (an insulating layer (second insulating layer) 27 [0035], Figures 2 and 8) ; a third thermal insulative sheet disposed on a third side of the first stack assembly (the insulating member 57A, insulating member 57B [0049], [0051], Figure 7) a fourth thermal insulative sheet disposed on a fourth side of the first stack assembly (insulating members 58A, 58B [0051], Figure 7); a thermally insulative tape (the adhesive layer (66, 67) [0075], adhesive tape 74 [0137], The protective sheet 88 is formed of rubber or resin [0140], [0146], [An insulating plate (not shown) [0138]) wrapped around the first thermal insulative sheet disposed on the first side of the first stack assembly, the second thermal insulative sheet disposed on the second side of the first stack assembly, the third thermal insulative sheet disposed on the third side of the first stack assembly and the fourth thermal insulative sheet disposed on the fourth side of the first stack assembly wherein the insulative tape has a first and second surface wherein one of the first and second surfaces has an adhesive disposed thereon for adhering the insulative tape to the first stack assembly thereby securing the first, second and third thermal insulative sheet to the first stack assembly (see Figs. 2, 7, 8, 11); and a housing containing an electrolyte (The electrode groups 5A and 5B, the sheet member 7, and the electrolyte are housed inside the container members 3A and 3B [0027]) , wherein the first stack assembly is disposed within an interior of the housing and submerged in the electrolyte (The electrolyte is held (impregnated) in each of the electrode groups 5A and 5B [0027]) .
