`
`under the first inventor to file provisions of the AIA.
`
`Response to Amendment

`
`Applicant's amendment, filed on 06/07/2023, has been entered. Claim 21 has
`
`been added. Claims 8-21 are now pendingin this application.
`
`Claim Rejections - 35 USC § 103
`
`3.
`
`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:
`
`Apatent fora claimed invention may notbe 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 artare suchthat the claimed invention as a whole would have
`been obvious beforethe effective filing date of the claimed inventionto a person having
`ordinaryskill in the art to which the claimed invention pertains. Patentability shall notbe
`negated by the manner in whichthe invention was made.
`
`The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148
`
`USPQ 459 (1966), that are applied for establishing a background for determining
`
`obviousness under 35 U.S.C. 103 are summarized as follows:

`
`Claims 8-16, and 19-20 are rejected under 35 U.S.C. 103 as being
`
`unpatentable over Kin (JP 2003123829 A) and further in view of Okuda (JP
`
`2013143224A) and Suehiro (WO 2017163557 A1) (refer to enclosed translations for
`
`citations).
`

`
`Regarding claim 8,
`
`e
`
`e
`
`e
`
`Kin teaches a cylindrical secondary battery [0001] comprising:
`
`abottomed cylindrical battery case [0007] having an opening [0006];
`
`an electrode group (Fig. 7, 2; [0006]);
`
`an electrolyte solution, the electrode group and the electrolyte solution being
`
`housed in the battery case [0003];
`
`e anda sealing member blocking the opening of the battery case (Fig. 1, 12;
`
`[0031], “cap assembly”),
`
`e wherein the electrode group includes a positive electrode (Fig. 1, 30; [0030)),
`
`e
`
`e
`
`anegative electrode (Fig. 1, 40; [0030)),
`
`anda separator placed between the positive electrode and the negative
`
`electrode (Fig. 1, 50; [0030));
`
`e
`
`and is formed by winding the positive electrode and the negative electrode with
`
`the separator therebetween [0030];
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 4
`
`the negative electrode includes a negative electrode current collector and a
`
`negative electrode mix layer formed on at least one principal surface of the
`
`negative electrode current collector (Fig. 1, 42; [0031]);
`
`the positive electrode includes a positive electrode current collector and a
`
`positive electrode mix layer formed on at least one principal surface of the
`
`positive electrode current collector (Fig. 1, 32; [0031]);
`
`the separator includes an inner non-contact region (Fig. 1; 54) which is located
`
`on the inner peripheral side of the electrode group and both surfaces of the inner
`
`non-contact region of the separator are not in contact with the negative electrode
`
`mix layer and not in contact with the positive electrode mix layer (Fig. 1, [0034]);
`
`the length of the inner non-contact region (Fig. 1; 54); it can be said that the inner
`
`non-contact region does not come into contact with the negative electrode due to
`
`it being further wound from separator 50 (Fig. 1, [0034]); the electrode group
`
`includes a cylindrical section formed by the negative electrode mix layer formed
`
`on a principal surface of the negative electrode current collector that is located
`
`innermost in the electrode group (Fig. 1, [0034]),
`
`and the cylindrical section has a hollow space (Fig. 1, [0034], see space within
`
`cylindrical section, wherein the hollow space is not required to be at the central
`
`portion),
`
`However, Kin fails to teach the non-contact region 5% or more of the length of
`
`the separator in a winding direction of the electrode group and the diameterof
`
`the cylindrical section is 2.5 mm or less.
`
`

`

`
`Okuda teachesthe central portion of a wound electrode body is formed by
`
`winding the innermost part of the separator to effectively suppress the depletion of
`
`electrolytic solution. Therefore, the suppression of electrolyte depletion is
`
`recognized as a result-effective variable dependent on the amountof winding,
`
`in
`
`which an increased amount of winding, which requires a greater length of the
`
`innermost separator, corresponds to an improved suppression of the electrolyte
`
`depletion. There would be reasonable expectation of success to attempt different
`
`length percent values of the non-contact region until the electrolyte depletion was
`
`suppressed. Therefore, it is not inventive to discover the optimum workable range or
`
`value by routine experimentation, and it would have been obvious to one of ordinary
`
`skill in the art before the effective filling date of the claimed invention, to modify Kin
`
`by employing an inner length of non-contact region being 5% or more of the length
`
`of the separator (see MPEP 2144.05 II.). However, modified Kin fails to teach the
`
`diameter of the core thickness 2.5 mm or less.
`
`Suehiro teaches a cylindrical battery (Fig. 10, 14) with a cylindrical core thickness
`
`is .7mm or more and 1.5 mmor less, which overlaps with the claimed range ([077];
`
`“when the diameter of the core 50 is too large, the battery capacity becomes small”).
`
`It would be obvious to one of ordinary skill of the art before the effective filing date to
`
`combine an innermost cylindrical section of 1.5 mm or less as taught by Suehiro with
`
`the cylindrical battery as taught by modified Kin in order to improve battery capacity.

`
`Regarding claim 9,
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 6
`
`Modified Kin teaches a cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), wherein the inner non- contact region is placed in an
`
`inner portion of the cylindrical section (Fig. 1; [0034)).
`

`
`Regarding claim 10,
`
`onweom
`Lise,
`So RS
`
`
`
`
`
`
`
` Ko:
`
`
`
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), wherein the separator hasafirst folded portion in the inner
`
`non-contact region (annotated Fig. 6, “first folded portion”; [0034]).
`
`8.
`
`Regarding claim 11,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 10
`
`(see elements of claim 10 above), wherein the separator is folded atthe first folded
`
`portion (annotated Fig. 6, 54, “first folded portion’; [0034]) to sandwich a portion of the
`
`negative electrode, as the separator is on both sides of the current collector for the
`
`negative electrode (annotated Fig. 6, “exposed section”; [0034]). The examiner notes
`
`that the separator 54 in Fig. 6 sandwiches the exposed section (annotated Fig. 6,
`
`“exposed section’; [0034]) because it is on both sides of the exposed section.
`
`9.
`
`Regarding claim 12,
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 7
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), wherein the negative electrode includes an exposed section
`
`whereat least one principal surface of the negative electrode current collector is
`
`exposed (annotated Fig. 6, “exposed section’) and which is located at an end section on
`
`the inner peripheral side of the electrode group (annotated Fig. 6, “exposed section’).
`
`10.
`
`Regarding claim 13,
`
`Modified Kin teaches cylindrical secondary battery according to Claim 12 (see
`
`elements of claim 12 above), wherein the exposed section is placed in an inner portion
`
`of the cylindrical section (annotated Fig. 6, “exposed portion’).
`
`11.
`
`Regarding claim 14,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 12
`
`(see elements of claim 12 above), wherein the exposed section has a second folded
`
`portion placed in the inner portion of the cylindrical section (annotated Fig. 6, “second
`
`folded portion’).
`
`12.
`
`Regarding claim 15,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 14
`
`(see elements of claim 14 above), but fails to teach wherein the exposed section is
`
`folded at the second folded portion together with the separator in the inner non-contact
`
`region. However, Okuda teaches wherein the exposed section is folded together with
`
`the separator in the inner non-contact region ([O006], “a central portion formed by
`
`winding or folding at least one of the innermost part of the negative electrode not coated
`
`with the substance and the innermostpart of the separator”). Additionally, Okuda
`
`teaches that the electrode may bent even further and positioned together with the
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 8
`
`separator inside the inner non-contact region ([0049], “You may makeit arrange|
`
`position to the other bending part 32 side in the center part of the body 11) to avoid
`
`compressing the inner region from both sides which can allow cracking and short circuit
`
`to occur [0035]. Therefore, it would be obvious to one of ordinary skill of the art before
`
`the effective filing date to combine the exposed section folded together with the
`
`separator in the inner non-contact region with the cylindrical secondary battery of Kin
`
`such that cracking in the inner region, and consequently a short circuit, is avoided.
`
`13.
`
`Regarding claim 16,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 12
`
`(see elements of claim 12 above), wherein the negative electrode mix layer formed on a
`
`principal surface of the negative electrode current collector that is located innermostof
`
`the electrode group (annotated Fig. 6, “electrode mix”) faces the exposed section with a
`
`plurality of the separator therebetween (Fig. 6, 54, see plurality of separators defined by
`
`the first and second folding region).

`
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), wherein the outside of the separator that is located on the
`
`outermostperipheral side of the electrode group (Fig. 1,52, outermost spiral hollow with
`
`white) is covered by the negative electrode current collector (Annotated Fig. 1, 42,
`
`“outermost peripheral separator’). The examiner notes that the term “covered” is a term
`
`dependent on an arbitrary orientation, such that if 50 were considered to be the
`
`outermost peripheral separator, despite Kin’s description to the contrary in [0033], 42
`
`would still cover the outermost peripheral separator in the opposite orientation.
`
`15.
`
`Regarding claim 19,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), wherein Suehiro the outside diameter of the cylindrical
`
`secondary battery (Suehiro; annotated Fig. 1, black arrow) is 6 mm orless, which is
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 10
`
`encompassed by the claimed range of 6.5 mm or less, in order to improve the technical
`
`significance [089] of a high-capacity small sized battery being realized [034]. Thus,it
`
`would be obvious to one of ordinary skill of the art before the effective filing date to use
`
`an outside diameter of 6.5 mm or less, as taught by Suehiro,
`
`in order to better prevent a
`
`short.
`
`16.
`
`Regarding claim 20,
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8). While Suehiro silent to the numberof turns present, and fails to
`
`depict the number of turns being three to ten (see Fig. 10, 14, number of turns depicted
`
`as two in the preferred embodiment with a 4.5 mm diameter [087]), Suehiro teaches
`
`alternate embodiments wherein the diameter of the canis 6 mmor less or 10 mm or
`
`less. Accordingly, it is clear that the number of turns in the alternate embodiment must
`
`overlap with the claimed range of 3-10 turns. Thus,
`
`it would be obvious to one of
`
`ordinary skill of the art before the effective filing date to use at least 3 turns ina
`
`cylindrical battery, as taught by as taught by modified Kin,
`
`in order to improve capacity
`
`while still maintaining a relatively small diameter.
`
`In the case where the claimed ranges
`
`"overlap orlie inside ranges disclosed bythe prior art" a prima facie case of
`
`obviousness exists. MPEP 2144.05
`
`17.
`
`Claim 17 is rejected under 35 U.S.C. 103 as being unpatentable over Kin (JP
`
`2003123829 A) and further in view of Okuda (JP 2013143224A), Suehiro (WO
`
`2017163557 A1), and Shiori (JP2001176482A) (refer to enclosed translations for
`
`citations).

`
`Regarding claim 17,
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 11
`
`Modified Kin teaches the cylindrical secondary battery according to Claim 8 (see
`
`elements of claim 8 above), but fails to teach wherein the separator including a base
`
`layer and a resin layer formed on at least one principal surface of the base layer, the
`
`resin layer having swelling properties for the electrolyte solution.
`
`Shiori teaches a polyvinylidene fluoride resin layer (Fig. 2b, 21) laminated with a
`
`reinforcing layer [0009], meeting the claimed base layer and corresponding to the
`
`feature in modified Kin as described above. Shiori teaches the resin layer swells while
`
`holding the electrolytic solution [0035], because increasing the liquid retaining property
`
`decreasesthe internal resistance of the battery [0004].
`
`It would be obvious to one of
`
`ordinary skill of the art before the effective filing date to combine the base layer and
`
`resin layer having swelling properties for the electrolyte solution as taught by Shiori with
`
`the cylindrical secondary battery as taught by Kin in order to decreasetheinternal
`
`resistance of the battery.
`
`19.
`
`Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Kin (JP
`
`2003123829 A) and further in view of Okuda (JP 2013143224A), Suehiro (WO
`
`2017163557 A1), and Kojima (JP 2008226500 A)(refer to enclosed translations for
`
`citations).
`
`Modified Kin teaches the cylindrical battery of claim 8 (see rejection of claim 8
`
`above), wherein a cylindrical portion has a hollow space (see rejection of claim 1
`
`above), but fails to teach wherein the inner non-contact region of the separator
`
`traverses the hollow space to partition the hollow space. Kojima teaches wherein the
`
`inner non-contact region of the separator traverses the hollow space to partition (Fig.
`
`4B, W5; [041], “split”) the hollow space [016],
`
`in order to simplify manufacturing,
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 12
`
`shortening production time (see abstract, [051], [(041]). Therefore, it would be obvious
`
`to one of ordinary skill of the art before the effective filing date to modify the battery of
`
`modified Kin with the inner non-contact region of the separator that traverses the hollow
`
`space to partition (Fig. 4B, W5; [041], “split’) the hollow space [016], as taught be
`
`Kojima, in order to simplify manufacturing, shortening the production time of the battery.
`
`Response to Arguments
`
`Applicant's arguments, see Remarks, filed 03/10/2023, have been fully
`
`considered and are not persuasive.
`
`Applicant argues that Kin teaches away from a hollow core. However, this is not
`
`persuasive, as Kin fails to teach away from a hollow core. Kin’s statement that “at this
`
`time,
`
`it is desirable that the innermost separator...be wound tightly (without gaps)” is
`
`interpreted not to teach away froma hollow core. Firstly, Kin teaches a hollow core
`
`(see rejection of claim 1 above) and Kojima teaches wherein the innermost separator is
`
`wound tightly (without gaps) before partitioning a hollow core (Fig. 46, W5; [041]). Kin’s
`
`admission of “at this time” implies that a tightly wound inner-most separator without
`
`gaps has a situational rather than general benefit, such that Kin doesn’t generally teach
`
`away from a tightly wound separator without gaps. The combination of Kin in view of
`
`Kojima.
`
`Accordingly, applicant’s arguments regarding the diameter and hollowness of the
`
`cylindrical section are not persuasive as Suehiro teaches a claimed diameter of 2.5 mm
`
`or less (see rejection of claim 1 above) and Kin does not teach awayfrom a hollow
`
`cylindrical section.
`
`

`

`Application/Control Number: 16/651 ,945
`Art Unit: 1728
`
`Page 13
`
`Applicants argues that the outside peripheral separator is not in contact with the
`
`negative electrode current collector. However, this is not persuasive,
`
`asit is the
`
`examiner’s position that the negative electrode current collector is in contact with
`
`outside peripheral separator, as shown in annotated Fig.
`
`1 (see rejection of claim 18
`
`above). The image of Fig.
`
`1 provided in the “Remarks”, received 06/07/2023, appear to
`
`have been overly-simplified, whiting out portions of the figure such that 42 appears to be
`
`mappedto a different element. The examiner notes that the term “covered” is a term
`
`dependent on an arbitrary orientation, not requiring direct physical contact, such thatif
`
`50 were considered to be the outermost peripheral separator, despite Kin’s description
`
`to the contrary in [0033], 42 would still cover the outermost peripheral separator in the
`
`opposite orientation.
`
`Applicant argues that all other claims should be allowed. However,this is not
`
`persuasive, as the rejections on all claims have been sustained.
`
`Conclusion
`
`The prior art made of record and notrelied upon is considered pertinent to
`
