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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 2, 4-6, and 8 are rejected under 35 U.S.C. 103 as being unpatentable over Jackson (U.S. Patent No. 10369872) in view of Cavender-Bares (U.S. Patent No. 9582002) and further in view of Allard, et al. (U.S. Patent No. 7979175).
Regarding claim 2, Jackson teaches: A method comprising: analyzing, by a computing system corresponding to a multi-operational land drone (Fig. 2, Col. 6, lines 59-67, Fig. 1, Col. 3, lines 44-47: Fig. 2, Col. 6, lines 59-67: "…computing device, laptop, tablet, or the like, to download data from or upload data to the controller [analysis by computing system]." ; Fig. 1, Col. 3, lines 44-47: "…planting operations, seeding operations, application operations, tillage operations, harvesting operations, and the like [operations – multi-operational land drone].")
Jackson does not teach sensor data that is obtained using one or more sensors corresponding to the multi-operational land drone; determining, by the computing system based on the analyzing of the sensor data, one or more operating upcoming environment conditions corresponding to an operating environment of the multi-operational land drone; the one or more upcoming operating environment conditions including one or more of: an amount of slope of the operating environment or a driving surface condition of the operating environment; and adjusting a load balancing system of the multi-operational land drone.
In a similar field of endeavor (autonomous platforms and systems for the purpose of managing an agricultural field while self-navigating between rows of crops), Cavender-Bares teaches: sensor data that is obtained using one or more sensors corresponding to the multi-operational land drone; (Fig. 15, Col. 10, lines 53-59: “…sensor (175). Such as one or more cameras, infrared sensors, ultrasonic sensors, or a combination thereof. In one embodiment, sensor (175) is mounted to the top of a telescoping tower or mast (127).”)
determining, by the computing system based on the analyzing of the sensor data, one or more operating upcoming environment conditions corresponding to an operating environment of the multi-operational land drone; (Fig. 21, Col. 15, lines 60-65: “…sensor (150) configured to monitor the conditions of a planted crop (106). For example, sensor (150) can use optical or other measurements to determine the abundance of plant pigments, such as chlorophyll [analyzing sensor data based on operating environment].”; Col. 10, lines 19-22: "Navigation module (124) can be configured to receive field orientation information and detect obstacles using a variety of inputs, including existing data about a particular agricultural field (102) [can determining upcoming environment conditions]")
the one or more upcoming operating environment conditions including one or more of: an amount of slope of the operating environment or a driving surface condition of the operating environment; (Col. 8, lines 46-53: “…autonomous vehicle platform (100) will soon encounter a side slope [amount of slope of operating environment]”)
and adjusting a load balancing system of the multi-operational land drone (Col. 8, lines 46-53: "In one embodiment, automated valves or pumps can be used to permit passage of the contents of tank (116) from one tank compartment to another. For example, where a baffle (120) exist to separate a right and left portion of tank (116), if it is known that autonomous vehicle platform (100) will soon encounter a side slope [approaching environment condition of increasing slope], the contents of tank (116) can be transferred from one side to the other to improve stability [adjusting load balance of land drone].").
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify Jackson to include the teachings of Cavender-Bares based on a reasonable expectation of success and motivation to improve the development of an autonomous vehicle platform which conducts various seasonal management tasks between the planted rows of an agricultural field (Cavender-Bares Col 4, lines 27-62).
The combination of Jackson and Cavender-Bares does not teach in response to the one or more upcoming operating environment conditions indicating one or more of: the multi-operational land drone approaching a tipping point; or a reduced traction condition of one or more wheels of the multi-operational land drone.
In a similar field of endeavor (control systems and methods for unmanned ground vehicles), Allard, et al. teaches: in response to the one or more upcoming operating environment conditions indicating one or more of: the multi-operational land drone approaching a tipping point or a reduced traction condition of one or more wheels of the multi-operational land drone (Col. 14, lines 30-34: "…localization sensor suite (602) fuses the data from each sensor in the suite together in a weighted fashion to achieve a more robust estimations of state [in response to one or more upcoming operating environment conditions] […] In some embodiments, the localization sensor suite (602) determines the orientation of the vehicle, such as its pitch, roll, or yaw in part to ensure that the vehicle is not in danger of tipping over on its side, for example [multi-operational land drone approaching tipping point].").
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of Jackson and Cavender-Bares to include the teaching of Allard, et al. based on a reasonable expectation of success and motivation to improve the process of controlling unmanned ground vehicles in response to environmental changes or operator intervention (Allard, et al.

Regarding claim 8, Jackson, Cavender-Bares, and Allard, et al. remain as applied to claim 2, and in a further embodiment, teach: The method of claim 2, further comprising selecting, by the computing system, for the multi-operational land drone to transition from a manual mode to one of a plurality of remote operation modes in response to a determination, based on the determined one or more operating environment conditions, that the operating environment poses a potential harm to an operator were the operator to be disposed on or in the multi-operational land drone (Allard, et al. Fig. 9, Steps (702-704), Col. 17, lines 31-37: "…manned operation mode (STEP 704) [manual mode], a remote unmanned tele-operation mode (STEP 706) [remote mode #1], an assisted remote tele-operation mode (STEP 708) [remote mode #2]" ; Allard, et al. Col. 21, line 65 to Col. 22, lines 1-6: "…receiving the mode select command (STEP 902) includes receiving a remote command (STEP 914) [selection of remote mode by computing system]. […] remote-controlled operation of the vehicle, i.e., the case where an operator maintains control over the vehicle when not physically present in the vehicle [definition of remote operation mode]."; Allard, et al. Col. 24, lines 15-21: "…removing an operator from harm's way during a dangerous application [operating environment poses a potential harm to an operator]").
Claim 9 is rejected as being unpatentable over Jackson (U.S. Patent No. 10369872), Cavender-Bares (U.S. Patent No. 9582002) and Allard, et al. (U.S. Patent No. 7979175) in view of Letscher, et al. (U.S. Patent No. 11186326).
Regarding claim 9, the combination of Jackson, Cavender-Bares, and Allard, et al. does not teach the method of claim 2, wherein the load balancing system includes one or more of: one or more adjustable weights; or one or more adjustable spring mechanisms.
In a similar field of endeavor (ballasting device for agricultural vehicles), Letscher, et al. teaches: The method of claim 2, wherein the load balancing system includes one or more of: one or more adjustable weights; or one or more adjustable spring mechanisms (Col. 12, lines 1-22: “…first ballasting arm (36) the first ballasting weight (38) and by the second ballasting arm (40) the second ballasting weight (42) are adjustable [adjustment operations with weights] […] the first and second ballasting arms (36), (40) are adjustable or pivotable in relation to one another from an open position [first position], in which the center of gravity S of the ballasting device (32) is at no distance or a minimum distance from the ballasting body (34), into a closed position [second position] in which the center of gravity S of the ballasting device (32) is at a maximum distance from the ballasting body (34).”).
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of Jackson, Cavender-Bares, and Allard, et al. to include the teaching of Letscher, et al. based on a reasonable expectation of success and motivation to improve the process of modifying the center of gravity of a ballasting device of an agricultural vehicle with respect to changing working conditions (Letscher Col. 3, lines 22-47).

Response to Arguments
Applicant's arguments filed October 22, 2025 have been fully considered but they are not persuasive.
Applicant asserted that claim 2 and amended claims 11 and 18 was patentable over Jackson (U.S. Patent No. 10369872) in view of Cavender-Bares (U.S. Patent No. 9582002) and further in view of Allard, et al. (U.S. Patent No. 7979175) because the references did not meet the entire claim limitation “and adjusting a load balancing system of the multi-operational land drone in response to the one or more upcoming operating environment conditions indicating one or more of: the multi-operational land drone approaching a tipping point; or a reduced traction condition of one or more wheels of the multi-operational land drone”. Specifically, Applicant asserts that in Allard et al. that there is no disclosure as to adjusting a load balancing system as part of the monitoring or “ensuring” process. Please note that Cavender-Bares (U.S. Patent No. 9582002) was cited in order to teach this feature. In Cavender-Bares, the process of adjusting the load balance of the machine uses “…automated valves or pumps can be used to permit passage of the contents of tank (116) from one tank compartment to another” within the agricultural vehicle and a baffle (120) separates both sides of the vehicle (Col. 8, lines 46-50). As a result, during a circumstance where the “…autonomous vehicle platform (100) will soon encounter a side slope”, or a region in which could lead to a possibility of the vehicle tipping over, a load balance can be achieved by moving “…the contents of tank (116) can be transferred from one side to the other to improve stability” (Col. 8, lines 50-53). Subsequently, it would have been obvious to combine Cavender-Bares with Jackson and Allard, et al. because Jackson teaches a remote-control mode for an autonomous agricultural vehicle (Col. 6, lines 35-37) and Allard, et al. teaches the process by which a sensor suite can be used to identify the vehicle’s orientation and identify when the vehicle is specifically reaching a tipping point (Col. 14, lines 30-34).
Therefore, it can be concluded that since the combination of Jackson, Cavender-Bares, and Allard, et al. reads on the claim limitation “and adjusting a load balancing system of the multi-operational land drone in response to the one or more upcoming operating environment conditions indicating one or more of: the multi-operational land drone approaching a tipping point; or a reduced traction condition of one or more wheels of the multi-operational land drone”, as stated in claim 2 and amended claims 11 and 18, the arguments presented by the Applicant are not persuasive, and the rejection is maintained.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure.
Schmitz, et al. (U.S. Patent Application Publication No. 20220009521) describes an autonomous farmland tractor which includes multiple sensors for the detection of an obstacle, a central processing unit (CPU) for receiving signals from the sensors and for providing control to the tractor, and a coupler to couple the tractor to another agricultural machine. The agricultural machine also contains obstacle detection sensors in order to connect the machine to the CPU and provide data to the CPU about the sensors’ location and specifications.
Foster, et al. (U.S Patent No. 10821829) describes an autonomous agricultural vehicle with a controller, a control interface, and a display connected to the controller.
Chowdhary, et al. (U.S. Patent Application Publication No. 20210158041) describes an apparatus and method for agricultural data collection and agricultural operations related to robot-based crop stem width estimation involving camera based sensors.
Applicant is considered to have implicit knowledge of the entire disclosure once a reference has been cited. Therefore, any previously cited figures, columns and lines should not be considered to limit the references in any way. The entire reference must be taken as a whole; accordingly, the Examiner contends that the art supports the rejection of the claims and the rejection is maintained.
