`
`DETAILED ACTION
`
`Notice of Pre-AlA or AIA Status
`
`The present application, filed on or after March 16, 2013, is being examined
`
`under the first inventor to file provisions of the AIA.
`
`Claim Status
`
`Claim 1 (Currently Amended)
`
`Claims 2-5 (Original)
`
`Claim 6 (New)
`
`Responseto Arguments
`
`Applicant's amendments and arguments, filed on 12/29/2020, have been fully
`
`considered but are not persuasive because the combination of the prior arts still reads
`
`on the amended claim 1. The new claim 6 has necessitated the new ground(s) of
`
`rejection presentedin this office action.
`
`Regarding the Applicant’s argumentthat the prior art(s) does/do not teach “the
`
`controller changesa setting value of a charging electric current of the second charging
`
`circuit for the sub-battery based on an amount of charge of the main battery.”, the
`
`Examiner respectfully disagrees because
`
`In responseto applicant's argument that there is no teaching, suggestion, or
`
`motivation to combine the references, the examiner recognizes that obviousness may
`
`be established by combining or modifying the teachings of the prior art to produce the
`
`claimed invention where there is some teaching, suggestion, or motivation to do so
`
`

`
`foundeither in the references themselves or in the knowledge generally available to one
`
`of ordinary skill in the art. See /n re Fine, 837 F.2d 1071, 5 USPQ2d 1596(Fed. Cir.
`
`1988), In re Jones, 958 F.2d 347, 21 USPQ2d 1941 (Fed. Cir. 1992), and KSR
`
`International Co. v. Teleflex, Inc., 550 U.S. 398, 82 USPQ2d 1385 (2007).
`
`In this case,
`
`Cummings doesnotexplicitly teach the controller changes a setting value of a
`
`charging electric current of the second charging circuit for the sub-battery based on an
`
`amount of charge of the main battery.
`
`However, Tatsumoto teaches in Fig. 10, charging a plurality of batteries abstract,
`
`lines 1-12; CC and CV charging mode [0008];
`
`the controller 964 changes [0085], lines 4-5 a setting value e.g.,1.0, 2.0, 3.0 A, of
`
`a charging electric current, corresponding to 97A, 97B, 97C of the second charging
`
`circuit 963 switching/selection for charging the sub-battery e.g., 97A or 97C based on
`
`an amount of charge, [0085]-[0087] of the main battery e.g., 97B.
`
`For example, based on the current charge amount of 97B is 80%per
`
`Tatsumoto’s Fig. 10B, then 97A and 97C can be charged with any current reduced
`
`starting from 3.0A, 2.0A, 1.0A. Tatsumoto’s Fig. 11 is to perform the batteries charging
`
`criteria per Fig. 10A that reduces charging loss [0011] [0012]; in which the battery 97A
`
`and 97C, for example, are charged to be ready as backup batteries to support the main
`
`battery 97B when required, e.g., the amount of charge of the battery 97B is not
`
`sufficient or low. Similarly, the dual batteries of Cummings are applicable for the same
`
`purpose. Then, the claim recitation in arguments has been disclosed.
`
`Accordingly, THIS ACTION IS MADE FINAL.

`
`Claim Rejections - 35 USC § 103
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all
`
`obviousnessrejections set forth 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 of thistitle, if the differences
`between the claimed invention andthe prior art are such that the claimed invention as a whole
`would have been obvious before the effectivefiling 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 1-4 are rejected under 35 U.S.C. 103 as being unpatentable over
`
`Cummings (U.S. 5818200), in view of Tatsumoto (U.S. 2015/0311731).

`
`amount of charce (managing or moritoring battery charge amount is implied by S102,
`
`S109, Fig. 11; and [0085]-[0087]} of the sub-baltery (97A or 97C, Fig. 10C). It would
`
`have been obvious to one of ordinary skill in the art before the effective filing date of the
`
`claimed invention to incorporate the controller changes a setting value of a charging
`
`electric current of the second charging circuit for the sub-battery based on an amount
`
`of charge of the main battery of Tatsumoto’s into Cummings’, in order to control or
`
`adjust the charging current corresponding to the current and boundary charge amount
`
`({0085]-[0087]; Tasumoto).
`
`Regarding claim 2, Cummings teachesthe electronic device according to claim 1, in
`
`view of Tatsumoto, wherein upon detection of replacement (abstract, lines 1-6) of the
`
`main battery (313 of 302, Fig. 3),
`
`Cumming doesnotexplicitly teach the controller sets the setting value of the
`
`charging electric current for the sub-battery to a first setting value in a case where the
`
`amount of charge of the main battery is equal to or larger than a predetermined
`
`threshold value, and the controller sets the setting value of the charging electric current
`
`for the sub-battery to a second setting value that is larger than the first setting value in a
`
`case where the amount of charge of the main battery is smaller than the predetermined
`
`threshold value.
`
`

`

`Application/Control Number: 16/041 ,831

`
`Tatsumoto teaches the controller (964, Fig. 10C) sets the setting value of the
`
`charging electric current (1.0, 2.0, 3.0A, Fig. 10A) for the sub-battery (e.g. 97A or 97C,
`
`Fig. 10C) to a first setting value (1A, Fig. 10A) in a case where the amountof charge of
`
`the main battery (e.g. 97B, Fig. 10C with charge amount 90%, Fig. 10A) is equal to or
`
`larger than a predetermined threshold value (90%, Fig. 10A), and
`
`the controller (964, Fig. 10C) sets the setting value of the charging electric
`
`current (1.0, 2.0, 3.0A, Fig. 10A) for the sub-battery (e.g. 97A or 97C, Fig. 10C) toa
`
`second setting value (2.0A or 3.0A, Fig. 10A) that is larger than the first setting value
`
`(1A, Fig. 10A) in a case where the amount of charge of the main battery (e.g. 97B, Fig.
`
`10C with current charge amount 80%or 70%, Fig. 10A) is smaller than the
`
`predetermined threshold value (90%, Fig. 10A).
`
`It would have been obvious to one of
`
`ordinaryskill in the art before the effective filing date of the claimed invention to
`
`incorporate the controller sets the setting value of the charging electric current for the
`
`sub-battery to a first setting value in a case where the amount of charge of the main
`
`battery is equal to or larger than a predetermined threshold value, and the controller
`
`sets the setting value of the charging electric current for the sub-battery to a second
`
`setting value that is larger than the first setting value in a case where the amount of
`
`charge of the main battery is smaller than the predetermined threshold value of
`
`Tatsumoto’s into Cummings’, in order to control or adjust the charging current
`
`corresponding to the current and boundary charge amount ([0085]-[0087]; Tasumoto).
`
`Regarding claim 3, Cummings teaches the electronic device according to claim 1, in
`
`view of Tatsumoto. Cummings doesnotexplicitly teach wherein when the amountof
`
`

`

`Application/Control Number: 16/041 ,831
`Art Unit: 2859
`
`Page 8
`
`charge of the main battery becomes smaller than a threshold value concerning the
`
`amount of charge of the main battery, the controller sets the setting value of the
`
`charging electric current for the sub-battery to a first setting value in a case where an
`
`amount of charge of the sub-battery is equal to or larger than a threshold value
`
`concerning the amount of charge of the sub-battery, and the controller sets the setting
`
`value of the charging electric current for the sub-battery to a second setting value thatis
`
`larger than the first setting value in a case where the amount of charge of the sub-
`
`battery is smaller than the threshold value concerning the amount of charge of the sub-
`
`battery.
`
`Tatsumoto teaches when the amountof charge (75%or 65%, Fig. 10A) of the
`
`main battery (e.g. 97A or 97C, Fig. 10C) becomes smaller than a threshold value (90%,
`
`Fig. 10A) concerning the amountof charge of the main battery (e.g. 97A or 97C, Fig.
`
`10C), the controller (964, Fig. 10C) sets the setting value of the charging electric current
`
`(1.0, 2.0, 3.0A, Fig. 10A) for the sub-battery (e.g. 97B, Fig. 10C) to a first setting value
`
`(1.0A, Fig. 10A) in a case where an amount of charge of the sub-battery (e.g. 97B, Fig.
`
`10C with charge amount 90%,Fig. 10A) is equal to or larger than a threshold value
`
`(90%, Fig. 10A) concerning the amount of charge of the sub-battery (e.g. 97B, Fig.
`
`10C), and
`
`the controller (964, Fig. 10C) sets the setting value of the charging electric
`
`current (1.0, 2.0, 3.0A, Fig. 10A) for the sub-battery (e.g. 97B, Fig. 10C) to a second
`
`setting value (2A, or 3A, Fig. 10A) that is larger than the first setting value (1.0A, Fig.
`
`10A) in a case where the amountof charge of the sub-battery (e.g. 97B, Fig. 10C with
`
`

`

`Application/Control Number: 16/041 ,831
`Art Unit: 2859
`
`Page 9
`
`charge amount 80%or 70%, Fig. 10A) is smaller than the threshold value (90%, Fig.
`
`10A) concerning the amountof charge of the sub-battery (e.g. 97B, Fig. 10C). It would
`
`have been obvious to one of ordinary skill in the art before the effective filing date of the
`
`claimed invention to incorporate when the amount of charge of the main battery
`
`becomes smaller than a threshold value concerning the amount of charge of the main
`
`battery, the controller sets the setting value of the charging electric current for the sub-
`
`battery to a first setting value in a case where an amount of charge of the sub-battery is
`
`equal to or larger than a threshold value concerning the amount of charge of the sub-
`
`battery, and the controller sets the setting value of the charging electric current for the
`
`sub-battery to a second setting value that is larger than the first setting value in a case
`
`where the amount of charge of the sub-battery is smaller than the threshold value
`
`concerning the amount of charge of the sub-battery of Tatsumoto’s into Cummings’, in
`
`order to control or adjust the charging current corresponding to the current and
`
`boundary charge amount ([0085]-[0087]; Tasumoto).
`
`Regarding claim 4, Cummings teaches the electronic device according to claim 1, in
`
`view of Tatsumoto, wherein electric power is supplied from the sub-battery (313 of 304,
`
`Fig. 3) to the load circuit (10, Fig. 1; powered up via 3126+314 of 304, Fig. 3; col. 4, lines
`
`6-11) in a case where the main battery (313 of 302, Fig. 3) is detached (abstract, lines 1-
`
`12; col. 1, lines 64-67; col. 2, lines 3-7, 28-30) from the electronic device (20, Fig. 3) while
`
`power of the electronic device (20, Fig. 3) is on.

`
`Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Cummings
`
`(U.S. 5818200), in view of Tatsumoto (U.S. 2015/0311731), as applied abovein claim 1,
`
`and further in view of Kano (U.S. 2011/0260689)
`
`Regarding claim 5, Cummings teaches the electronic device according to claim 1,
`
`in
`
`view of Tatsumoto. The combination does not explicitly teach wherein the sub-battery has
`
`a smaller capacity than the main battery and is fixed in the electronic device.
`
`Kano teaches the sub-battery (18, Fig. 1, or battery #2, Fig. 2; low capacity battery,
`
`fast charge with large current, longer life [0028] [0047]) has a smaller capacity ([0028],
`
`lines 13-14) than the main battery (17, Fig. 1, or battery #1, Fig. 2; lithium ion battery, high
`
`capacity, shorter life, charging current tend to being down to small value) andis fixed in
`
`the electronic device (10, Fig. 1).
`
`It would have been obvious to one of ordinary skill in
`
`the art before the effective filing date of the claimed invention to incorporate the sub-
`
`battery has a smaller capacity than the main battery and is fixed in the electronic device
`
`of Kano’s into Cummings’,
`
`in view of Tatsumoto’s,
`
`in order to provide a longer
`
`charge/discharge cycle life of the lower capacity battery compared to the higher capacity
`
`battery ([0028], last 4 lines; Kano).
`
`Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Cummings
`
`(U.S. 5818200), in view of Tatsumoto (U.S. 2015/0311731), as applied abovein claim 1,
`
`and further in view of Matsuda (1.5. 5563493}
`
`Regarding claim 6, Cummings teachesthe electronic device according to claim 1, in

`sub-battery to close internal switch for selection of the sub-battery if main battery is
`
`absent; abstract).
`
`The combination does not explicitly teach (a second detector which is configured
`
`io} Guipul a detection signal indicating wheiher or not the main battery is attached to the
`
`electronic device.
`
`Matsuda teaches detection the presence ar absence of the connection of the
`
`batlery (S2, 54, 56 Fig. 9 or 12 of 17} and output a delection signal (col. &, lines 56-60}
`
`indicating whether ar not the battery is attached to the electronic device: display for
`
`indicating the state of the battery (claim 7}.
`
`It would have been obvious to one of
`
`ordinaryskill in the art before the effective filing date of the claimed invention to
`
`incorporate 4 detection signal indicating whether or nat the battery is allached ta the
`
`electronic device of Matsuda’s into Cummings’, in view of Tatsumoto’s, so that the
`
`detection signal can be used to update the system status to the user e.g., via an LED
`
`indicator or display.
