Claim(s) 20 are rejected under 35 U.S.C. 103 as being unpatentable by US PG pubs 20200218286 – Tamasato et al. hereinafter as TAMASATO in view of US PG Pub 20200149248 – Ram-on et al. hereinafter as RAM-ON in view of US PG Pub 20100183416 – Ishii et al. hereinafter as ISHII Regarding Claim 20 TAMASATO / RAM-ON discloses claim 8: TAMASATO does not disclose: wherein working device comprises a first working device connected to the main body and a second working device connected to the main body. TAMASATO does disclose of a single working device, ISHII disclose of more than one working device: wherein working device comprises a first working device connected to the main body and a second working device connected to the main body.(fig. 1 double working device) Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was filed to substitute a single working device mechanism of TOMASATO for a double working device that includes a first working device and a second working device connected to the main body by ISHII. Doing so merely constitutes the substitution of one known work device mechanism for another to produce the predictable result of more capable working device excavator (MPEP 2143, subsection I, B). Additionally, Examiner notes that ISHII discloses of having two working arms that allows users to perform some functions that would just otherwise not be possible with only one working arm (ISHII – para. 0002) Claim(s) 22 – 23, and 27 are rejected under 35 U.S.C. 103 as being unpatentable over US PG Pubs 20200149248 – Ram-On et al. hereinafter as RAM-ON in view of US PG pubs 20200218286 – Tamasato et al. hereinafter as TAMASATO Regarding Claim 22 RAM-ON discloses claim 21: RAM-ON discloses of utilizing drone for taking images of site operations for an autonomous heavy machinery operation, however does not explicitly disclose of the drone takes off from a take-off and landing portion on the main body and flies toward the distal end member. TAMASATO discloses: wherein the drone takes off from a take-off and landing portion on the main body and flies toward the distal end member. ( see figure 3, - take-off and landing zones – 16 with QR codes) Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was filed to substitute the body of the working machine of RAM-ON for a body of the machine that includes a takeoff and landing portion for a drone on the main body of a working machine by TOMASATO. Doing so merely constitutes the substitution of one known work device mechanism for another to produce the predictable result of recharging and docking a drone (MPEP 2143, subsection I, B). Additionally, Examiner notes that TOMASATO discloses that the operation system includes a drone having a GNSS receiver, and a working machine having a take-off and landing port and is configured so that positional information on the working machine is acquired by the GNSS receiver of the drone to be placed on the take-off and landing port. (TOMASATO – para. 0005) Regarding Claim 23 RAM-ON / TAMASATO discloses claim 22: RAM-ON discloses: The assistance method according to claim 22, wherein an image data of the distal end member captured by the drone ( para. 0032 – discloses of a camera on drone capturing excavator distal end of excavator boom. ) is transmitted to a device different from the drone. (para. 0026 - device different from drone would be data that takes images from drone i.e. cloud) Regarding Claim 27 RAM-ON discloses claim 21: RAM-ON discloses utilizing drone for taking images of site operations for an autonomous heavy machinery operation, however does not explicitly disclose of the drone takes off from a take-off and landing portion on the main body and flies toward the distal end member. TAMASATO discloses: 27. The assistance method according to claim 21, wherein the main body is provided with a take-off and landing portion on which the drone takes off and lands, and the predetermined altitude is higher than the take-off and landing portion. ( see figure 3, - take-off and landing zones – 16 with QR codes, para. 0022 - the drones 14 recognize images of the position marks 24Aand 24B of the take-off and landing ports 16 of the working machine 18 by means of the cameras 40 whose photographing directions are oriented directly downward, while flying above a position that has been acquired by the low-precision GNSS receiver 34 and at which the working machine 18 is predicted to exist, and above a region around the position. In this case, the drones 14 fly at heights higher than the highest section of the working machine 18. The positions and heights of the drones 14 are acquired by the high-precision GNSS receivers 12 of the drones 14. The height of the highest section of the working machine 18 is recognized in advance based on a design value of the working machine 18, the terrain data, and the like. ) Therefore, it would have been obvious to one having ordinary skill in the art at the time the invention was filed to substitute the body of the working machine of RAM-ON for a body of the machine that includes a takeoff and landing portion for a drone on the main body of a working machine by TOMASATO. Doing so merely constitutes the substitution of one known work device mechanism for another to produce the predictable result of recharging and docking a drone (MPEP 2143, subsection I, B). Additionally, Examiner notes that TOMASATO discloses that the operation system includes a drone having a GNSS receiver, and a working machine having a take-off and landing port and is configured so that positional information on the working machine is acquired by the GNSS receiver of the drone to be placed on the take-off and landing port.
