Application No.: 16/979,581
`
`Introduction
`
`REMARKS
`
`Claims 1-4, 7-10 and 15 are pending, of which claim 1 is independent.
`
`Claims 5, 6 and 11-14 have been cancelled without prejudice. No new matter has been
`
`added.
`
`Patentability under 35 U.S.C. § 102
`
`Claims 1-15 were rejected under 35 U.S.C. § 102(a)(1) as being anticipated by Yoshii
`
`(WO 2017/110023). Without conceding any correctness of the rejections, Applicant traverses
`
`these rejections for at least the following reasons.
`
`Applicant submits that Yamato fails to disclose that a first proportion is lower than a
`
`second proportion, where the first proportion is a proportion of a mass of the conductive agent
`
`in a total mass of the manganese dioxide and the conductive agentin at least one wholepellet
`
`positioned in a middle portion in a height direction of the stack, and the second proportion is a
`
`proportion of a mass of the conductive agent in a total mass of the manganese dioxide and the
`
`conductive agent in at least one whole pellet positioned in one of end portions in the height
`
`direction of the stack, as recited by claim 1.
`
`With respect to the first proportion and the second proportion of claim 1 above, the
`6666.
`
`Examinerasserted
`
`““‘with respect to 100 parts by mass of manganese dioxide” correspondsto a
`
`directly proportional amountof the conductive agent in each pellet. In other words, when the
`
`density of manganese dioxideis lowerin the central pellet(s), the conductive agent in these
`
`pellets will be lower as well.), referring to paragraph [0044] of Yoshii.
`
`However, the Examiner’s assertion is incorrect. Claim 1 recites that the first (second)
`
`

`

`Application No.: 16/979,581
`
`proportion is a proportion of a mass of the conductive agent in a total mass of the manganese
`
`dioxide and the conductive agent in at least one whole pellet. Paragraph [0044] of Yoshii
`
`discloses “Content of the electrically conductive agent in a positive electrode is 3-10 mass parts
`
`with respect to 100 mass parts of manganese dioxide, Preferably it is 4-6 mass parts,” which
`
`merely defines the amount of conductive agent with respect to the amount of manganese dioxide.
`
`In other words, when the amount of manganese dioxide is small, the amount of conductive agent
`
`is also small. Thus, even if the amount of manganese dioxide is small (which means the amount
`
`of conductive agent is also small), the proportion of a mass of the conductive agent with respect
`
`to the total mass of the manganese dioxide and the conductive agent is the same,i.c., 4-6 wt% as
`
`disclosed at paragraph [0044]. As such, the Examiner’s assertion in the present Office Action is
`
`incorrect and has no merit.
`
`Assuch, claim 1 and all claims dependent thereon are patentable over the cited reference.
`
`

`

`Application No.: 16/979,581
`
`CONCLUSION
`
`Having fully respondedto all matters raised in the Office Action, Applicant submits that
`
`all claims are in condition for allowance, an indication for whichis respectfully solicited. If
`
`there are any outstanding issues that might be resolved by an interview or an Examiner’s
`
`amendment, the Examineris requested to call Applicant’s attorney at the telephone number
`
`shownbelow.
`
`To the extent necessary, a petition for an extension of time under 37 C.F.R. § 1.136 is
`
`hereby made. Please charge any shortage in fees due in connection with the filing of this paper,
`
`including extension of time fees, to Deposit Account 500417 and please credit any excess fees to
