In some embodiments, electrical sub-assemblies according to the disclosure can also be configured for other uses, such as to control other features, actuations, or movements of power machines.” (Durkin Para 0094), “On some power machines, implement interface 170 can include an implement carrier, which is a physical structure movably attached to a work element. The implement carrier has engagement features and locking features to accept and secure any of a number of implements to the work element. One characteristic of such an implement carrier is that once an implement is attached to it, it is fixed to the implement (i.e. not movable with respect to the implement) and when the implement carrier is moved with respect to the work element, the implement moves with the implement carrier. The term implement carrier as used herein is not merely a pivotal connection point, but rather a dedicated device specifically intended to accept and be secured to various different implements. The implement carrier itself is mountable to a work element 130 such as a lift arm or the frame 110. Implement interface 170 can also include one or more power sources for providing power to one or more work elements on an implement. Some power machines can have a plurality of work element with implement interfaces, each of which may, but need not, have an implement carrier for receiving implements. Some other power machines can have a work element with a plurality of implement interfaces so that a single work element can accept a plurality of implements simultaneously.

Therefore, the high voltage interlock circuit 111 is controlled to block the high voltage applied to the corresponding high voltage connector. The high voltage interlock circuit 111 supplies a high voltage to the high voltage connector and serves to detect an interlock open signal, so it is possible to easily cut off the high voltage supplied to the high voltage connector.]” (Jeong Para 0055), “[In the above state, when the vehicle is started and power is supplied to the vehicle, the battery management unit 100 built in the battery pack 100 is connected to the plurality of connectors 101 - 106 to open the interlock.

The motivation for combining Durkin and Jeong is the same as that recited for claim 12 above.
In regards to claim 6, Durkin in view of Jeong teaches of the system of claim 1, wherein, in response to determining a fault status as the status of the electrically powered implement, the one or more electronic processors are configured to control the routing of power from the electrical power source of the power machine via the connector assembly by preventing power from being supplied from the electrical power source to an electric actuator of the electrically powered implement (“[In the above state, when the vehicle is started and power is supplied to the vehicle, the battery management unit 100 built in the battery pack 100 is connected to the plurality of connectors 101 - 106 to open the interlock.

The motivation for combining Durkin and Jeong is the same as that recited for claim 12 above.
In regards to claim 7, Durkin in view of Jeong teaches of the system of claim 6, wherein the electric actuator of the electrically powered implement is configured to receive, via the connector assembly, power from the electrical power source via a second electric circuit of the electrically powered implement that is arranged in parallel with the first electric circuit(“[The first circuit line 14 passes through a plurality of connectors 12 for connecting high voltage components, respectively, and the second circuit line 18 also passes through a plurality of inlets 16 connected to each connector, respectively. .]” (Jeong Para 0016), “[Here, among the interlock circuit lines including the first and second circuit lines 14 and 18, resistors R1, R2, and R3 are formed at portions where each connector 12 and the inlet 16 are separated from each other. connected in parallel.]” (Jeong Para 0017), “[When it is determined that the interlock open signal has occurred, the high voltage interlock circuit 111 is controlled to cut off the high voltage supplied to the corresponding high voltage connector.

In regards to claim 8, Durkin in view of Jeong teaches of the system of claim 6, wherein, in response to determining the fault status as the status of the electrically powered implement, the one or more electronic processors are configured to control the routing of power to the electrically powered implement via the connector assembly by disabling the electrical power source (“[In the above state, when the vehicle is started and power is supplied to the vehicle, the battery management unit 100 built in the battery pack 100 is connected to the plurality of connectors 101 - 106 to open the interlock.

In regards to claim 9, Durkin in view of Jeong teaches of the system of claim 8, wherein the one or more electronic processors are configured to disable the electrical power source in response to determining the fault status as the status of the electrically powered implement by executing a safe torque off function for the power machine and the electrically powered implement (“[In the above state, when the vehicle is started and power is supplied to the vehicle, the battery management unit 100 built in the battery pack 100 is connected to the plurality of connectors 101 - 106 to open the interlock.

The motivation for combining Durkin and Jeong is the same as that recited for claim 12 above.
In regards to claim 10, the claim recites analogous limitations to claim 13 and is therefore rejected on the same premise.
In regards to claim 11, the claim recites analogous limitations to claim 15 and is therefore rejected on the same premise.
Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Durkin et al. (US 20210270004; hereinafter Durkin; already of record from IDS) in view of Jeong et al. (KR 20220026094; hereinafter Jeong; already of record from IDS: see attached English translation for citations), as applied to claim 12 above, further in view of Koekemoer (US 20190057295).
In regards to claim 4, Durkin in view of Jeong teaches of the system of claim 1, wherein the electrically powered implement … operable by an electric motor that is powered by the electrical power source of the power machine (“The implement interface 270 also includes an implement power source 235 available for connection to an implement on the lift arm structure 230. The implement power source 235 includes pressurized hydraulic fluid port to which an implement can be coupled. The pressurized hydraulic fluid port selectively provides pressurized hydraulic fluid for powering one or more functions or actuators on an implement. The implement power source can also include an electrical power source for powering electrical actuators and/or an electronic controller on an implement. The electrical power source 235 also exemplarily includes electrical conduits that are in communication with a data bus on the excavator 200 to allow communication between a controller on an implement and electronic devices on the loader 200. It should be noted that the specific implement power source on loader 200 does not include an electrical power source.” (Durkin Para 0108), “In this regard, referring now to FIG. 27, the lift arm structure 430 according to the illustrated embodiment further includes a connector opening 776 that may be outfitted with a connector 780 for transmitting power and control signals to an electronically powered or controlled implement or other electrical components arranged at the front of the power machine 400. For example, returning to FIG. 16B, electrical wires, represented by arrows 784, may be routed from an electrical source, e.g., the controls subassembly 420 to the connector 780. Particularly, the connector 780 can be used to provide power and control signals from the controls subassembly 420 to high-powered electronic components and attachments, such as, e.g., electronic actuators or motors of an implement that are configured to execute work operations.” (Durkin Para 0218)).
However, Durkin in view of Jeong does not specifically teach of wherein the electrically powered implement includes at least one of an auger, a sweeper, a mulcher, a chipper, a breaker, a grapple, or a saw operable by an electric motor that is powered by the electrical power source of the power machine.
Koekemoer, in the same field of endeavor, teaches of wherein the electrically powered implement includes at least one of an auger, a sweeper, a mulcher, a chipper, a breaker, a grapple, or a saw operable by an electric motor that is powered by the electrical power source of the power machine (“FIG. 2A illustrates a front view of a breaker attachment 200 for a mining machine according to one embodiment. FIG. 2B illustrates a side view of the breaker attachment 200. The breaker attachment 200 includes a hammer bit 205 and a breaker body 210. The breaker body 210 further includes a connection interface 215 and houses a hydraulic-driven percussion mechanism. The connection interface 215 includes a coupling 220 that physically secures the breaker attachment 200 to a reciprocal coupling on a mining machine (e.g. at the end of a boom arm). The connection interface 215 further includes hydraulic connectors to receive hydraulic fluid that drives the percussion mechanism. When driven, the percussion mechanism percussively drives the hammer bit 205. In other words, in operation, the hammer bit 205 repeatedly translates in and out of the breaker body 210 along a longitudinal axis 225. Accordingly, the breaker attachment 200, via the hammer bit 205, drills and hammers a worked material, such as concrete or rock, to break apart the worked material. The breaker attachment 200 may further include a wireless breaker tag 230, which is explained in further detail below.” (Para 0019), see also Para 0025).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the implement operatable by an electric motor, as taught by Durkin in view of Jeong, to include being a breaker, as taught by Koekemoer, with a reasonable expectation of success in order to drill and hammer the worked material and therefore breaking apart the material (Koekemoer Para 0019).
