Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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:
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, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing 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.
Claim(s) 1-10, 13-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gauthier et al. US Pub 2021/0276425 (hereinafter Gauthier) in view of Berels et al. US Pub 2018/0029474 (hereinafter Berels).
Regarding claim 1, Gauthier teaches an electrical power system (¶ 0020; vehicle system) for a vehicle having a traction motor (¶ 0021; the traction motor(s) 110) and a plurality of electrical grids (¶ 0021 and fig. 1, elements 113/115; power rails), comprising:

Greyscale
a rechargeable energy storage system (RESS) (fig. 1, element 101) having a high voltage (HV) interface (connection between element 101 and element 109) configured for exchanging HV power with the traction motor (¶ 0021; HV source 101 is
coupled to a first power rail 107 via a DC/DC converter 109. First power rail 107 is a general-purpose rail that provides power for the traction motor(s) 110) and
a low voltage (LV) interface (connected with LV battery 103 and LV battery 105) configured for exchanging LV power with the electrical grids (fig. 1, elements 113, 115); and
a redundant distribution system (¶ 0020; the vehicle system described herein provides a redundant power distribution system) having a plurality of safety switches (117, 119) configured for redundantly connecting the electrical grids (113, 115) with the LV interface such that each of the electrical grids remains operable and connected to the LV interface during a disconnect event (claim 4; the power distribution system wherein said first set of lights receives power from said first battery when said second circuit detects said fault corresponding to said second safety critical power rail, and wherein said second set of lights receives power from said second battery when said first circuit detects said fault corresponding to said first safety critical power rail).
Gauthier does not disclose a redundant distribution system further includes a plurality of busbars configured for redundantly connecting the electrical grids.
However, Berels further discloses a vehicle system includes multiple DC-DC converter circuits, vehicle batteries, and vehicle power distribution buses (busbars) in abstract. Each vehicle power distribution bus 116 overload protection circuit 132 may monitor the collective current drawn by all vehicle loads 110 connected to the output terminals 128 of the respective vehicle power distribution bus 116, compare the current draw to the predetermined threshold, and shut off (e.g., disconnect) the output terminals 128 if the current draw exceeds the predetermined threshold. When power provided to the first power supply input 130 fails, the vehicle load 110 may use the electrical power provided to the second power supply input 130 to continue operating in ¶¶ 0019-0020.
It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to modify Gauthier to incorporate with the teaching of Berels by including vehicle power distribution buses in the system, because it would be advantageous to tolerate certain failures and the power supply allows the vehicle to fulfil certain safety critical functionalities.

Regarding claim 2, Gauthier in view of Berels teaches wherein: the electrical grids each include a LV bus (Gauthier, fig. 1, element 113; power rail) configured for distributing the LV power (Gauthier, from low voltage power source 103) to one or more loads (fig. 1, elements 137, 139); and
the busbars (Berels, fig. 2, element 116: vehicle power distribution buses) are arranged in a redundant configuration (¶ 0020; a redundant power distribution system) characterized by each of the LV buses (Gauthier, fig. 1, elements 113, 115) being independently (Berels, fig. 2) connectable to two or more of the busbars (Berels, fig. 2, element 116a and 116b and ¶ 0011; each of the vehicle batteries 114 are electrically connected to multiple vehicle power distribution buses 116).
Regarding claim 3, Gauthier in view of Berels teaches the electrical power system further comprising:
a plurality of aggregating units (Gauthier, fig. 1, elements 117, 119) each having a plurality of inputs (Gauthier: one input from the power rail, such as element 113; receiving input signal from ECU1, 141) commonly connectable (directly/indirectly connected) to an output (Gauthier, see fig. 1),
wherein the aggregating units (Gauthier, 117, 119) each include the output connected (indirectly connected) to one of the LV buses of the electrical grids (Gauthier, 113/115) and the inputs separately connected (separately and indirectly connected) to one of the two or more of the busbars (Berels, ¶¶ 0019-0020; vehicle power distribution buses).

the RESS includes a plurality of cell groups (Gauthier, fig. 1, element 103, 105, 101) and a power converter (Gauthier, fig. 1, element 109),
the power converter operable for converting electrical power from one or more of the cell groups (Gauthier, from HV battery, 101) into a plurality of LV outputs (Gauthier, ¶ 0023; DC/DC converter 109 maintain the charge levels on batteries 103 and 105 [two LV batteries]),
each of the LV outputs correspondingly delivering LV power (Gauthier, from two batteries 103, 105) to a connected to one power rail (115)
Gauthier fails to disclose a plurality of power converters are able to deliver LV power to a connected to one of the busbars.
Berels discloses a vehicle system includes multiple DC-DC converter circuits (fig. 2, element 122), vehicle batteries (114), and vehicle power distribution buses 116 in Abstract. The DC-DC converter may have an input terminal 118 connected to an input power line 104 and an output terminal 120 connected to an output power line 104 in ¶ 0015. Each of the DC-DC converter circuits 112 and each of the vehicle batteries 114 are electrically connected to multiple vehicle power distribution buses 116 in ¶ 0011. Therefore, each power converter is able to convert from the battery cell groups into a plurality of LV outputs.
It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to modify Gauthier to incorporate with the teaching of Berels by including vehicle power distribution buses in the system, because it would be advantageous to tolerate certain failures and the power supply allows the vehicle to fulfil certain safety critical functionalities.

Gauthier in view of Berels fails to disclose a third busbar. However, the prior art discloses the busbars including a first busbar, a second busbar. It would have been obvious to a person having ordinary skill in the art before the effective filing date to provide at least three busbars since it has been held that the mere duplication of the essential working parts of a device involves only routine skill in the art in order to supply operatable power to more loads.

the busbars including a first busbar (116a), a second busbar (116b),
wherein: the first busbar (116a) connects to (indirectly connects) each of the first LV outputs (120, 120), the first primary input (118), and the first junction input (104); the
second busbar (116b) connects to each of the second LV outputs (fig. 2, element 120), the second secondary input (118), and the second junction input (104);
