`
`2.
`
`The Applicant’s amendment/request for reconsideration filed on May 8, 2020 was
`
`received. Claim 1 was amended.

`
`prior Office action.
`
`Specification
`
`3.
`
`The objection to the specification has been withdrawn in view of the amendment to the
`
`title.
`
`Claim Rejections - 35 USC § 103
`
`4.
`
`The claim rejection under 35 U.S.C. 103 as unpatentable over Saito et al. in view of
`
`Hotta et al. on claims 1, 2, and 4 are maintained with modifications to reflect the amendments to
`
`the claims.
`
`5.
`
`The claim rejection under 35 U.S.C. 103 as unpatentable over Saito et al. in view of
`
`Hotta et al. as applied to claims 2 and 4 respectively and further in view of Yoon et al. on claims
`
`3 and 5 are maintained with modifications to reflect the amendments to the claims.
`
`6.
`
`Claims 1, 2 and 4 are rejected under 35 U.S.C. 103 as being unpatentable over Saito et
`
`al. (JP 5686130, machine translation) in view of Hotta et al. (US 2014/0295248).

`Application/Control Number: 15/873,175
`Art Unit: 1727

`
`Regarding claim 1, Saito discloses an all solid state battery [0001] comprising: a positive
`
`electrode layer (positive electrode body 3) which includes a positive electrode current collector
`
`(1a) and a positive electrode material mixture layer (2) formed on the positive-electrode current
`
`collector (Fig 2), wherein the positive-electrode material mixture layer includes at least a
`
`positive-electrode active material and a binder [0025, 0027]; a negative electrode layer
`
`(negative electrode body 8) which includes a negative electrode current collector (1c) and a
`
`negative-electrode material mixture layer (5) formed on the negative-electrode current collector
`
`(Fig 2), wherein the negative-electrode material mixture layer includes at least a negative-
`
`electrode active material and a binder [0025, 0027]; and a solid electrolyte layer (4) which is
`
`disposed between the positive electrode layer and the negative electrode layer, and includes at
`
`least a solid electrolyte having ion conductivity [0025], wherein concentration of a solvent
`
`included in at least one layer selected from the group consisting of the positive electrode
`
`material mixture layer, the negative-electrode material mixture layer, and the solid electrolyte
`
`layer is equal to or smaller than 50 ppm (no solvent) [0013, 0020, 0027-0029], but is silent
`
`towards the concentration of the binder.
`
`Hotta teaches a negative electrode for a secondary battery [0013] where the
`
`concentration of the binder included in negative electrode material mixture layer is distributed so
`
`as to be higher on the current collector side [0030-0031, 0063-0064].
`
`It would have been
`
`obvious to one of ordinary skill in the art when the invention was effectively filed to provide a
`
`distribution of the concentration of the binder in the electrodes to be higher in proximity to the
`
`current collector of Saito because Hotta recognizes that such a distribution of the binder
`
`material provides for the prevention of the separation of the current collector, alleviate stress of
`
`volume expansion, and thereby improve the cycle characteristics of the battery [0031].
`
`Regarding claim 2, Saito discloses the all solid state battery of Claim 1, wherein the
`
`positive-electrode material mixture layer includes a conductive assistant [0059].
`
`

`

`Application/Control Number: 15/873,175

`
`Regarding claim 4, Saito discloses the all solid state battery of Claim 1, wherein the
`
`negative-electrode material mixture layer includes a conductive assistant [0059].
`
`7.
`
`Claims 3 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over Saito et al.
`
`in view of Hotta et al. as applied to claims 2 and 4 above respectively, and further in view of
`
`Yoon et al. (US 2016/0190546).
`
`The teachings of Saito and Hotta as discussed above are herein incorporated.
`
`Regarding claims 3 and 5, Saito and Hotta are silent regarding concentration of the
`
`conductive assistant included in the positive or negative electrode material mixture layer, the
`
`concentration in proximity to the respective current collector is higher than the concentration in
`
`proximity to the solid electrolyte layer.
`
`Yoon teaches a positive electrode composite for an all solid battery (Abstract) where the
`
`amount of conductive material is about zero at the region in contact with the electrolyte layer
`
`and increased at the region in contact with the metal current collector [0032] so that the
`
`generation of a short circuit with the opposing electrode may be minimized, mobility of ions and
`
`electrons are increased, internal resistance may be minimized, and an electrochemical reaction
`
`area may be maximized [0034].
`
`It would have been obvious to one of ordinary skill in the art
`
`when the invention was effectively filed to provide an amount of conductive material to be about
`
`zero at the region in contact with the electrolyte layer and increased at the region in contact with
`
`the metal current collector for the electrodes of Saito in view of Hotta because Yoon recognizes
`
`that such a distribution of conductive material within electrodes inclusive of conductive material
`
`provides for the minimization of short circuits with the opposing electrode, mobility of ions and
`
`electrons are increased, internal resistance may be minimized, and an electrochemical reaction
`
`area may be maximized [0034].

`
`Response to Arguments
`
`8.
`
`Applicant's arguments have been fully considered but they are not persuasive.
`
`Applicant’s principal arguments are:
`
`(a) Hotta does not disclose the concentration gradient of the binder described in claim 1.
`
`In response to Applicant’s arguments, please consider the following comments:
`
`(a) Applicant’s argued for “gradients” is defined by the scope of the limitations of claim 1 to be
`
`encompassed by a difference in binder concentration in proximity to the current collector to be
`
`higher than the concentration in proximity to the solid electrolyte layer. As clearly pointed out in
`
`the rejection above, Hotta recognizes “concentration of the binder included in negative electrode
`
`material mixture layer is distributed so as to be higher on the current collector side” clearly
`
`making obvious the limitations of the claim. A mere statement that the prior art of record does
`
`not meet the limitations does not make it so.

`
`Conclusion
`
`9.
`
`Applicant's amendment necessitated any new grounds 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 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.
