`
`
`Remarks
`
`The Applicants have amended Claim1 to include the subject matter of Claim3,
`
`Claim 3 has been cancelled in view ofthe inclusion of that subject matter into Claim 1.
`
`Claim 4 has also been amended to depend from Claim 1
`
`in view ofthe cancellation of
`
`Claim 3.
`
`Finally, Claim 7 has similarly been amendedin viewofthe cancellation of Claim 3.
`
`Entry of the above amendments and cancellation into the official file and consideration
`
`on the merits is respectfully requested.
`
`The Applicants enclose a new Fig. 4 and respectfully request that it be entered into the
`
`official file.
`
`The drawings stand objected to with respect to the claimed insulator which prevenis
`
`direct mechanical and electrical contacts between the end faces of the winding and the flat
`
`bottom of top areas must be shown. The Applicants note that original Claim 4 shows such an
`
`insulator with respect to reference numbers 411 and 412. However,the originally submitted Fig.
`
`4 shows a button cell that is closed in a classical manner with an edge of the cell cup 401 being
`
`beaded inward over an edge of the cell top 402. New Fig. 4 has been modified such that the
`
`button cell 400 is closed without being beaded over in accordance with Claim | and, also, in
`
`accordance with the claimed feature wherein the insulator prevents direct and electrical contact
`
`between the end faces of the winding in the flat bottom and top areas. Withdrawal of the
`
`objections to the drawings is respectfully requested.
`
`Claims ], 2, 6, 10 and 11 stand rejected under 35 USC §102 as being anticipated by
`
`Nakayama. The Applicants respectfully submit that the rejection is moot in view of the addition
`
`EAST\75846501.1
`

`
`JLab/Cambridge, Exh. 1002, p. 333
`
`JLab/Cambridge, Exh. 1002, p. 333
`
`
`
`+
`of the subject matter of Claim 3 into Claim 1. Withdrawal ofthe rejection is respectfully
`
`requested.
`
`Claims 3-5. 9. 12 and 13 stand rejected under 35 USC §103 over the combination of
`
`Suzuki with Nakayama. The Applicants note that the rejection is technically moot with respect
`
`to cancelled Claim 3. Nonetheless, the Applicants will address the substance ofthat rejection as
`
`it could theoretically apply to Claims } and 11,
`
`The rejection frankly acknowledges that Nakayama does not disclose a spiral winding.
`
`Henee, the rejection turns to Suzuki for such disclosure. However, the Applicants respectfully
`
`submit that importing the teachings of Suzuki
`
`into Nakayama would still result in a different
`
`button cel! and a different method of producing a button cell as recited in Claims 1 ana 11.
`
`respectively.
`
`Suzuki indeed discloses a spiral winding (Fig. 2). However, the end faces of the winding
`
`in Fig. 2 of Suzuki do not face in the direction of the flat bottom area and the flat top area. This
`
`difference is important. The Applicants explain in para. [0020] of their specification that a right-
`
`angled alignment of electrode layers (to the flat bottom and top areas)
`
`is unexpectedly
`
`advantageous. Lithium electrodes have a volume expansion and shrink during charging and
`
`discharging. Ifa lithium electrode is in the form ofa flat layer, in particular in the form ofa flat
`
`layer being spirally winded,
`
`the expansion/shrink is directional. Mechanical forces resulting
`
`from the expansion/shrink do act in this case in a radial direction much stronger than in an axial
`
`direction.
`
`This allows the use of a housing of a housing cup and a housing top whichis closed
`
`without being beaded over. All mechanical forces resulting fromthe charging and discharging
`
`processes can be absorbed bythe (radial) casing area and not bythe flat bottom and top areas.

`
`JLab/Cambridge, Exh. 1002, p. 334
`
`JLab/Cambridge, Exh. 1002, p. 334
`
`
`
`The Applicants respectfully submit that Suzuki (as well as Nakayama) fails to disclose,
`
`teach or suggest this unexpected advantage and inherentlyfails to disclose, teach or suggest the
`
`structure which results in this advantage. Hence, even fone skilled in the art were to importihe
`
`teachings of Suzuki into Nakayamaasset forth in the rejection, both the resulting button cells
`
`and the method of making such a button cell would be different from the subject matter of
`
`independent Claim 1. Withdrawal ofthe rejection is accordingly respecttully requested.
`
`Claims 7, 8 and 14 stand rejected under 34 USC $103 over the farther combination of
`
`Cantave with Suzuki and Nakayama. The Applicants respectfully submit that Cantave fails to
`
`cure the deficiencies set forth above with respect to the combination ef Suzuki with Nakayama,
`
`Withdrawal of the rejection is respectfully requested.
`
`In Hpht of the foregoing, the AppHcants respectfully submit that the entire application is
`
`now in condition for allowance, whichis respectfully submiiied.

`[Detailed Description of the Invention]
`[Field of the Invention]
`[0001]
`The present invention relates to the sized cell (for example, a button type battery, a coin type cell)
`provided with the winding electrode group.
`[Background of the Invention}
`Toc02]
`The spread of a portable electron and communication equipment, such as a small video camera, a
`cellular phone, PDA, and a notebook computer, was remarkable, rechargeable batteries, such as a
`rechargeable lithiurn-ion battery and a nickel hydrogen storage battery, were put in practical use as
`these power supplies, and development towards smal! weight saving and high capacity—ization has been
`performed briskly.
`10003]
`In addition to the flow of the further miniaturization of a portable equipment, a rechargeable battery is
`required as a power supply of the apparatus made indispensable [ a miniaturization called a wrist
`watch ], Small rechargeable batteries, such as a button form and a coin form, have been put in
`practical use by uses, such as a power supply for backup of SRAM and RTC to which discharge is
`performed with the light joad whose discharge current is a number ~ a tens of microA grade, and a
`main power supply of a changing-battery unnecessary wrist watch.
`[0004]
`As for the structure of small rechargeable batteries, such as these button type and a coin form, what
`is shown in Fig.10 is common, That is, that by which the positive electrode case 21 which serves as a
`positive pole terminal was caulked via the insulating gasket 23 as a well-closed container in the metal
`negative electrode cases 22 which serve as a negative pole terminal is used. Inside this well-closed
`container, one the positive electrode 24 and the anode 25 of the shape of a tablet whose diameteris
`smaller than the opening diameter of the insulating gasket 23 are stored at a time, respectively.
`Between the positive electrode 24 and the anode 25, the separator 26 which made the electrolysis
`solution impregnate interposes.
`160005]
`Since small rechargeable batteries, such as such a button form and a coin form, are simple for
`structure, they are excellent in mass production nature, and have the characteristics that a
`miniaturization is possible.
`{oo0s]
`However, small rechargeable batteries, such as a button form of the structure shown above and a coin
`form, have the insufficient characteristic at the time of discharging in the high current demanded as a
`main power supply of a portable device, and are not suitable as a main power supply of a portable
`device,
`[0007]
`A miniaturization is indispensable about a rechargeable lithium-ion battery, a nickel hydrogen storage
`battery, etc. which have been used by the miniaturization of persona! digital assistants, such as a small
`video camera, a cellular phone, PDA, and a notebook computer, as a main power supply on the other
`hand (for example, a Patent document 1, 2), The manufacturing method of a rechargeable lithium-ion
`battery or a nickel hydrogen storage battery is described simply. First, the charge collector consisting
`of a matallic foil or a metal net is applied or filed up with an active material layer, and an electrode is
`formed. An electrode group is produced by winding or laminating these electrodes after welding the tab
`terminal for current collection to the formed electrode. Bending was intricately performed to the tab
`terminal for currant collection furthermore taken out from the electrode group, it welded to a safety
`element, an electrode pin, an electrode can, etc,, and the cell was manufactured. This appearance
`takes a complicated manufacturing process to manufacture of these rechargeable batteries, and its
`work is complicated. It is necessary to provide space and parts in a cell for short prevention of a tab
`terminal, or to incorporate many parts, such as a safety element, in a cell. Therefore, in these
`rechargeable batteries, the miniaturization was dramatically difficult and had reached the lirnit
`substantially in the actual condition,

`{0008}
`It ts the object of this invention to make the heavy loading characteristic of sized cells, such as a
`button form and a coin form, improve, without impairing productivity.
`fMeans for solving problem]
`{0009}
`The laminated material which the sized cell concerning the present invention is stored in a container
`and the aforementioned container, anid contains a positive electrode and an anode is a sized cell
`possessing the flat shape electrode group wound spirally,
`The aforementioned flat shape electrode group is united with the aforementioned winding axis by
`winding the aforementioned laminated material spirally, where at least one electrode is fixed to a
`winding axis among the aforementioned positive electrode and the aforementioned anode.
`[0070]
`Here, a flat shape electrode group means the electrode group which has the structure where the
`height of the winding axial direction of an electrode group is smaller than the size of a direction
`vertical to a winding axis.
`[Effect of the Invention]
`{ooi1]
`According to the present invention, the sized cell which can improve a heavy loading characteristic
`can be provided, without impairing productivity.
`[Best Mode of Carrying Out the Invention]
`[0012]
`.
`The inventors found out the method of storing a wound type electrode group with safety and sufficient
`productivity in the case of sized cells, such as a button form and a coin form, as a result of repeating
`research about improvementin the heavy loading characteristic of a sized cell. Thereby, as compared
`with the convertional sized cell, the heavy loading characteristic improved by leaps and bounds,

`Namely, the metal negative electrode cases which serve as a negative pole terminal and the meta!
`positive electrode cases which serve both as a positive pole terminal, Fitting is carried out via an
`insulating gasket and the aforementi
