Regarding claim 35: Tse teaches the limitation as applied to claim 21 above. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Miyazawa because “…an effect is achieved in that malfunction is prevented by reliably causing the power semiconductor element to be conductive when a control signal to cause the power semiconductor device to be conductive is input to the semiconductor device”. See Miyazawa at para. [0097]. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Echigo because in an electric vehicle a battery supplies charged electric power to a driving motor via an inverter that converts DC power into AC power. See Echigo at para. [0022] – [0023]. Claim(s) 17, 18, 31 and 32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tse in view of Miyazawa, as applied to claims 16 and 30 above, in further view of Bayerer et al., US Publication No. 2016/0056132 A1. Regarding claim 17: Tse and Miyazawa teach all the limitations of claim 16 above, and Tse further teaches: (see fig. 3) wherein the power units (10) include a row of power units that are disposed on the first substrate (100), the row…comprises at least one corresponding power unit (10) arranged in a first direction Tse and Miyazawa but do not expressly teach: corresponding power units in each row of the plurality of rows of power units are electrically connected by a first corresponding connecting part. In an analogous art, Bayerer teaches: (see fig. 21) wherein the power units (1) include a plurality of rows (21, 22, 23, 24) of power units that are disposed on a first substrate (70), each row of the plurality of rows (21, 22, 23, 24) of power units comprises at least one corresponding power unit (1) arranged in a first direction (r2), and corresponding power units (1) in each row of the plurality of rows (21, 22, 23, 24) of power units are electrically connected by a first corresponding connecting part (4). See Bayerer at para. [0095] – [0097]. Bayerer further teaches: 18. The packaged structure according to claim 17, wherein the first corresponding connecting part (4) comprises a conductor (e.g. bonding wire), the conductor is in a multi-arch bridge shape, the conductor comprises a plurality of arch structures and a connecting part (e.g. at trough of the bridges) connected between adjacent arch structures, and the connecting part is electrically connected to the power units, fig. 21. Regarding claim 31: Bayerer teaches the limitations as applied to claim 17 above Regarding claim 32: Bayerer teaches the limitations as applied to claim 18 above It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Bayerer because this enables the plurality of power units to be connected in series. See Bayerer at para. [0095]. Claim(s) 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tse in view of Miyazawa, as applied to claim 16 above, in view of Casey et al., US Publication No. 2007/0057284 A1. Regarding claim 26: Tse teaches all the limitations of claim 16 above, and further teaches a power unit of the power units comprises a power chip, para. [0043]. Tse does not expressly teach: a surface of the power chip and that has a pin is away from the first substrate. In an analogous art, Casey teaches: a surface of the power chip (72) and that has a pin (“input/output pins) is away from a first substrate (74), para. [0006] – [0008]. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Casey because the exposed pins enable the connection of bonding wires (71) to the power chip (71), para. [0007]. Claim(s) 27 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tse in view of Miyazawa, as applied to claim 16 above, in view of Prechtl et al., US Publication No. 2017/0025523 A1. Regarding claim 27: Tse teaches all the limitations of claim 16 above, but does not expressly teach: a housing, wherein the housing has accommodation space inside, and the first substrate and the second substrate are located inside the housing. In an analogous art, Prechtl teaches: a housing, wherein the housing has accommodation space inside for semiconductor chips, para. [0076]. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Prechtl to form “a housing, wherein the housing has accommodation space inside, and the first substrate and the second substrate are located inside the housing” because housing provides protection against external impacts. See Prechtl at para. [0076]. Claim(s) 28 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tse in view of Miyazawa, as applied to claim 16 above, in view of Kanschat et al., DE 102006040435 B3 (see attached English machine translation). Regarding claim 28: Tse teaches all the limitations of claim 16 above, but does not expressly teach: wherein a first region on the housing and that corresponds to a second surface of the first substrate has a first notch, and wherein a second region on the housing and that corresponds to the control unit has a second notch. In an analogous art, Kanschat teaches: (see figs. 6-7) wherein a first region on the housing (40) and that corresponds to a second surface a the first substrate has a first notch (53), and wherein a second region on the housing…has a second notch (51). See Kanschat at pages 9-10 It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Kanchat to form “wherein a first region on the housing and that corresponds to a second surface of the first substrate has a first notch, and wherein a second region on the housing and that corresponds to the control unit has a second notch” because the notches to provide for mechanical attachment. See Kanschat at pages 9-10. . Claim(s) 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tse in view of Miyazawa, as applied to claim 16 above, in view of Pan et al., US Publication No. 2020/0006186. Regarding claim 29: Tse teaches all the limitations of claim 16 above, and further teaches 120A functions as heat sink, para. [0032]. Tse does not expressly teach: wherein a first heat sink is disposed on a second surface of the first substrate, and wherein a second heat sink is disposed on a surface of the control unit that faces away from the second substrate. In an analogous art, Pan teaches a heat sink (118) disposed on a second surface of substrate (102), para. [0058], fig. 1. It would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to modify the teachings of Tse with the teachings of Kanchat to form “wherein a first heat sink is disposed on a second surface of the first substrate, and wherein a second heat sink is disposed on a surface of the control unit that faces away from the second substrate” because heat transfer enhancements improve temperature control within a package.
