`
`DETAILED ACTION
`
`Response to Amendment
`
`Claims 1-4 and 6-12 are currently pending. Claim 5 has been cancelled. The
`
`previous objection to the specification is withdrawn. The amended claim 1 does
`
`overcome the previously stated 102 and 103 rejections. However, upon further
`
`consideration, claims 1-4 and 6-12 are rejected under the following new 102 and 103
`
`rejections. This action is made FINAL as necessitated by the amendment.
`
`Claim Rejections - 35 USC § 102/103
`
`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 madein this Office action:
`
`A personshall 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 effectivefiling date of the claimed
`invention.
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all
`
`obviousnessrejections setforth 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.
`
`Claim(s) 1, 3,6, and 11 are rejected under 35 U.S.C. 102(a)(1) as anticipated by
`
`or, in the alternative, under 35 U.S.C. 103 as obvious over Kato et al (US
`
`2016/0042878).
`
`
`
`Application/Control Number: 16/659,770
`Art Unit: 1729
`
`Page 3
`
`Regarding claims 1, 3, 6, and 11, Kato et al discloses a lithium ion secondary
`
`battery comprising: a positive electrode; a negative electrode; and an electrolyte,
`
`wherein the positive electrode comprises: a current collector “100” (positive electrode
`
`current collector); an active material layer “115” (positive electrode mixture layer)
`
`including positive electrode active material particles; and a resin layer “105”
`
`(intermediate layer / cured product) provided between the current collector and the
`
`active material layer, wherein the resin layer comprises a polyolefin-based emulsion
`
`particles modified with a carboxylic acid (cured product of a curable resin having a
`
`carboxyl group); and a conductive material (conductive agent) such as carbon powders,
`
`wherein the conductive material is 5 to 50 parts by mass; wherein a composition (cured
`
`product of the curable resin) is cured onto a conductive substrate (current collector) to
`
`form the resin layer (intermediate layer) by baking between 80°C to 240°C, wherein an
`
`example of 110°C inherently has a curing degree of the cured product of the curable
`
`resin that is 30% or more and 90%or less ((0037],[0042],[0044], [0067]-[0070],[0079]).
`
`Claim Rejections - 35 USC § 103
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all
`
`obviousnessrejections setforth 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.
`
`Claims 1, 3, 4, and 6-11 are rejected under 35 U.S.C. 103 as being unpatentable
`
`over Turi et al (US 5478676) in view of Kato et al (US 2016/0042878).
`
`
`
`Application/Control Number: 16/659,770
`Art Unit: 1729
`
`Page 4
`
`Regarding claims 1, 3, 6, 10, and 11, Turi et al discloses a lithium battery
`
`(secondary battery) comprising: a cathode (positive electrode); an anode (negative
`
`electrode); and an electrolyte, wherein the cathode comprises: a support “17” (positive
`
`electrode current collector); a cathode electrode layer (positive electrode mixture layer)
`
`including lithium manganese oxide (positive electrode active material particles); and a
`
`primer layer “18” (intermediate layer / cured product) provided between the support and
`
`the cathode electrode layer, and wherein the primer layer comprises a cured productof
`
`ethylene acrylic acid (curable resin) having a carboxyl group; and a conductivefiller
`
`(conductive agent); wherein a curing degree of the cured product of the curable resin is
`
`construed as being 100%; wherein the primer layer comprises 5 to 70%by weight of
`
`conductivefiller; wherein the primer layer further comprises polyvinylidene fluoride
`
`(fluorine resin) and a massratio of curable resin to the fluorine resin that is 1:1.95;
`
`wherein examples of the conductivefiller include carbon black (carbon particles) (col. 3,
`
`lines 3-7 and lines 54-58, col. 4, lines 31-34, Examples 1 and 12-14).
`
`However, Turi et al does not expressly teach a curing degree of the cured
`
`productof the curable resin that is 30% or more and 90%or less (claim 1).
`
`Kato et al teaches the conceptof curing a composition (cured productof the
`
`curable resin) onto a conductive substrate (current collector) to form a resin layer “105”
`
`(intermediate layer) by baking between 80°C to 240°C, wherein an example of 110°C
`
`inherently has a curing degree of the cured product of the curable resin that is 30%or
`
`more and 90%or less ([0067],[0079)).
`
`Therefore, it would have been obvious to one of ordinary skill in the art at the
`
`time the invention was made to modify the Turi primer layer to include a curing degree
`
`
`
`Application/Control Number: 16/659,770
`Art Unit: 1729
`
`Page 5
`
`of the cured productof the curable resin that is 30% or more and 90%or lessin order to
`
`optimize the adhesion of the conductive substrate with the resin layer while maintaining
`
`the PTC function of the resin layer ([0067]).
`
`Regarding claim 4, Turi et al discloses a thicknessof the primer layer
`
`(intermediate layer) that is 0.5 to 100 um (col. 4, lines 44-45).
`
`However, Turi does not expressly teach a thickness of the intermediate layer that
`
`is 0.1 um or more and 10 um or less.
`
`However, it would have been obvious to one of ordinary skill in the art at the time
`
`the invention was made to modify the Turi primer layer to include a thicknessthatis 0.1
`
`um or more and 10 um or less because in a case wherethe claimed ranges overlap or
`
`lie inside ranges disclosed bythe prior art a prima facie case of obviousnessexists.
`
`(/n
`
`re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d
`
`1575, 16 USPQ 2d 1934 (Fed. Cir. 1990)). There is no evidenceofcriticality of the
`
`claimed thicknessof the intermediate layer.
`
`Regarding claims 7-9, Turi discloses a primer layer that further comprises a non-
`
`conductivefiller such assilica or titanium dioxide (insulating inorganic material) (col. 4,
`
`lines 40-43).
`
`However, Turi does not expressly teach a content of the insulating inorganic
`
`material is 1 mass% or more and 100 mass%or less in the cured product (claim 7);
`
`a sum content of the conductive agent and the insulating inorganic material that is 25
`
`mass%or more and 100 mass%or less in the cured product (claim 8); a massratio of
`
`the insulating inorganic material to the conductive agent that is in the range of 1:0.05 to
`
`1:70 (claim 9).
`
`
`
`Application/Control Number: 16/659,770
`Art Unit: 1729
`
`Page 6
`
`However, it would have been obvious to one of ordinary skill in the art at the time
`
`the invention was made to modify the Turi primer layer to include a content of the
`
`insulating inorganic material is 1 mass% or more and 100 mass%or less in the cured
`
`product; a sum content of the conductive agent and the insulating inorganic material
`
`that is 25 mass% or more and 100 mass%or less in the cured product; or a massratio
`
`of the insulating inorganic material to the conductive agent thatis in the range of 1:0.05
`
`to 1:70 because it has been held that the discovery of an optimum value of a result
`
`effective variable in a Known processis ordinarily within the skill of the art. In re Boesch,
`
`205 USPQ 215 (CCPA 1980). The content of the insulating inorganic material is a
`
`results effect variable of optimizing the mechanical strength, surface roughnessor
`
`conductivity of the primer layer (col. 4, lines 40-43). Where the general conditions of a
`
`claim are disclosedin the prior art, it is not inventive to discover the optimum or
`
`workable ranges by routine experimentation. /n re Aller, 220 F.2d 454. 456, 105 USPQ
`
`233, 235 (CCPA 1955)). There is no evidenceofcriticality of the claimed content of the
`
`insulating inorganic material.
`
`Claims 2 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over
`
`Turi et al in view of Kato et al as applied to claim 1 above, and further in view of
`
`Shiozaki et al (US 2016/0190566).
`
`Regarding claim 2, Turi et al as modified by Kato et al does not expressly teach
`
`at least some of the positive electrode active material particles having at least a part
`
`that extends into the intermediate layer.
`
`
`
`Application/Control Number: 16/659,770
`Art Unit: 1729
`
`Page 7
`
`Shiozaki et al discloses a positive electrode mixture layer that is rolled with a
`
`current collector coated with a protective layer which inherently results in at least some
`
`of the positive electrode active material particles having at least a part that extends into
`
`the protective layer ([0045)).
`
`Therefore, it would have been obvious to one of ordinary skill in the art at the
`
`time the invention was made to modify the Turi/Kato cathode to include at least some of
`
`the positive electrode active material particles having at least a part that extends into
`
`the intermediate layer in order to further bond the cathode electrode layer to the coated
`
`current collector, thereby preventing delamination of the cathode electrode layer.
`
`Regarding claim 12, Turi et al as modified by Kato et al does not expressly teach
`
`a positive electrode active material particles that includeslithium nickel composite oxide
`
`particles.
`
`Shiozaki et al discloses a positive electrode active material that is a lithium-
`
`transition metal oxide such as LixCoyNi1-yO2 ([0024)).
`
`Therefore, the invention as a whole would have been obvious to one of ordinary
`
`skill in the art at the time the invention was made becausethe disclosure of Shiozaki
`
`indicates that LixCoyNi1-yO2 is a suitable material for use as a positive electrode active
`
`material. The selection of a known material based on its suitability for its intended use
`
`has generally been held to be prima facie obvious (MPEP §2144.07). As such, it would
`
`be obvious to use LixCoyNi1-yOz.

`
`Responseto Arguments
`
`Applicant's arguments with respect to claim(s) 1-4 and 6-12 have been
`
`considered but are moot because the new groundof 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
`
`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 shortenedstatutory period for reply to this final action is set to expire THREE
`
`MONTHS from the mailing date of this action.
`
`In the eventa first reply is filed within
`
`TWO MONTHS ofthe mailing date ofthis final action and the advisory action is not
`
`mailed until after the end of the THREE-MONTH shortenedstatutory period, then the
`
`shortenedstatutory period will expire on the date the advisory action is mailed, and any
`
`extension fee 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 date of this final action.
