Office Action

§102 §103
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The amendment filed on 05/28/2026 has been entered and fully considered. Claims 1, 8, 12, and 19 have been amended. Claims 7, 13, and 20 have been canceled. Claims 21-23 have been newly added. Claims 1-6, 8-12, 14-19, and 21-23 are pending in Instant Application. Response to Arguments Applicant's arguments filed 05/28/2026 have been fully considered but they are not persuasive. Regarding 102 rejection: Applicant argues that McKinnis, JR fails to teach the claimed feature of "wherein the controller is configured to automatically adjust the desired operating speed as part of the response", recited in claim 1. The examiner respectfully disagrees. The Applicant is reminded that the claims are given their broadest reasonable interpretation. The limitation merely recites that the desired operating speed, of the belt, see previous limitations of claim 1, is automatically changed (adjusted) based on a provided input (response). With that being said, Examiner would like to point to paragraph [0062] of the McKinnis, JR reference where it states that “the controller 180 automatically adjusts the belt 170 speed to match the input belt speed. In some embodiments, the controller 180 can adjust the belt 170 speed if there is any difference between the desired and measured belt 170 speeds”. This indicates that the controller will automatically adjust the belt speed based on the desired belt speed. Therefore, McKinnis, JR does teach "wherein the controller is configured to automatically adjust the desired operating speed as part of the response" and as such meets the scope of the claimed subject matter. Applicant argues that McKinnis, JR fails to teach the claimed feature of "wherein the automatic response is one or more of modifying a header speed, reducing a vehicle speed, and adjusting a roll gap" and "wherein the operating conditions comprise a header speed, a vehicle speed, and a roll gap and the automatic response comprises modifying one or more of the operating conditions", recited in claims 12 and 19. The examiner respectfully disagrees. The Applicant is reminded that the claims are given their broadest reasonable interpretation. The limitations merely recite that the one of the following header speed, reducing vehicle speed, or adjusting a roll gap is adjusted (modified) based on the response (input). With that being said, Examiner would like to point to paragraph [0062] of the McKinnis, JR reference where it states that “the controller 180 automatically adjusts the belt 170 speed to match the input belt speed” and “if the belt 170 speed is measured to be about 5% less or about 5% greater than the set desired speed, the controller 180 can automatically adjust the belt 170 speed to match the input belt speed”. Also, paragraph [0047] where it states that “the harvester can include a system that monitors and regulates/adjusts the speed of both the header and crop merger system belts based on the input belt speeds by the operator in a synchronized or substantially synchronized manner”. This indicates that both the belt speed AND the speed of the header will be adjusted (modified) based on the input (response) the operator gave. Once the operator has given an input, the controller will automatically adjust the belt speed to the desired belt speed and the speed of the header based on the system and controller monitoring the belt speed. Therefore, McKinnis, JR does teach "wherein the automatic response is one or more of modifying a header speed, reducing a vehicle speed, and adjusting a roll gap" and "wherein the operating conditions comprise a header speed, a vehicle speed, and a roll gap and the automatic response comprises modifying one or more of the operating conditions" and as such meets the scope of the claimed subject matter.

Claim Rejections - 35 USC § 103 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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103(a) 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. Claims 4-5 and 17-18 are rejected under 35 U.S.C. 103 as being unpatentable over McKinnis, JR. et al. (USPGPub 2019/0327897) in view of Bezanilla et al. (USPGPub 2025/0214783). As per claim 4, McKinnis, JR. does not explicitly mention wherein the controller is configured to provide a recommended belt speed to a user via a display. However Bezanilla does disclose: wherein the controller is configured to provide a recommended belt speed to a user via a display (see at least paragraph 0048; wherein the UI may include an interface element for monitoring and adjusting the speed of the conveyor belt 120. The UI may also display the recommended belt speed for various weights or types of items being transported). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Bezanilla with the teachings as in McKinnis, JR. The motivation for doing so would have been to improve the safe transportation of items, see Bezanilla paragraph 0011. As per claim 5, Bezanilla discloses wherein the controller is configured to determine the recommended belt speed based on operating conditions of the agricultural machine (see at least paragraph 0048; wherein the UI may include an interface element for monitoring and adjusting the speed of the conveyor belt 120. The UI may also display the recommended belt speed for various weights or types of items being transported). As per claim 17, McKinnis, JR. does not explicitly mention wherein the user-selected belt speed is a recommended belt speed generated by the controller based on operating conditions. However Bezanilla does disclose: wherein the user-selected belt speed is a recommended belt speed generated by the controller based on operating conditions (see at least paragraph 0048; wherein the UI may include an interface element for monitoring and adjusting the speed of the conveyor belt 120. The UI may also display the recommended belt speed for various weights or types of items being transported). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Bezanilla with the teachings as in McKinnis, JR. The motivation for doing so would have been to improve the safe transportation of items, see Bezanilla paragraph 0011. As per claim 18, McKinnis, JR. does not explicitly mention wherein the automatic response is to shut down the merger belt assembly when the actual belt speed is not within a shutdown threshold established by the desired belt speed with the controller. However Bezanilla does disclose: wherein the automatic response is to shut down the merger belt assembly when the actual belt speed is not within a shutdown threshold established by the desired belt speed with the controller (see at least paragraph 0045; wherein the control system 150 may incorporate one or more safety mechanisms including, e.g., emergency stop buttons, overload alerts, and automatic shutdown protocols in case of malfunctions or excessive strain on the conveyor system 100). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Bezanilla with the teachings as in McKinnis, JR. The motivation for doing so would have been to improve the safe transportation of items, see Bezanilla paragraph 0011. Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over McKinnis, JR. et al. (USPGPub 2019/0327897), in view of Bezanilla et al. (USPGPub 2025/0214783), and further in view of Trowbridge et al. (USPGPub 2021/0237982). As per claim 6, McKinnis, JR. and Bezanilla do not explicitly mention wherein the controller is configured to consider one or more of a header speed, a vehicle speed, and a roll gap as operating conditions of the agricultural machine. However Trowbridge does disclose: wherein the controller is configured to consider one or more of a header speed, a vehicle speed, and a roll gap as operating conditions of the agricultural machine (see at least paragraph 0050; wherein adjusting one or more operational parameters of the roller 330, the header 200, and/or the agricultural harvester 100 via the controller 350 (e.g., to adjust the ground speed of the agricultural harvester 100). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Trowbridge with the teachings as in McKinnis, JR. and Bezanilla. The motivation for doing so would have been to increase flexibility, see Trowbridge paragraph 0021. Claim 9 is rejected under 35 U.S.C. 103 as being unpatentable over McKinnis, JR. et al. (USPGPub 2019/0327897) in view of Trowbridge et al. (USPGPub 2021/0237982). As per claim 9, McKinnis, JR. does not explicitly mention wherein the controller is configured to consider one or more of a header speed, a belt slip, a vehicle speed, and a roll gap for the operating conditions. However Trowbridge does disclose: wherein the controller is configured to consider one or more of a header speed, a belt slip, a vehicle speed, and a roll gap for the operating conditions (see at least paragraph 0050; wherein adjusting one or more operational parameters of the roller 330, the header 200, and/or the agricultural harvester 100 via the controller 350 (e.g., to adjust the ground speed of the agricultural harvester 100). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Trowbridge with the teachings as in McKinnis, JR. The motivation for doing so would have been to increase flexibility, see Trowbridge paragraph 0021. Claims 10-11 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over McKinnis, JR. et al. (USPGPub 2019/0327897) in view of Babler et al. (USPGPub 2021/0045292). As per claim 10, McKinnis, JR. does not explicitly mention wherein the controller is configured to determine the desired belt speed command from data from the agricultural machine, the data comprising one or more of a header speed, a throw distance, and a header load. However Babler does disclose: wherein the controller is configured to determine the desired belt speed command from data from the agricultural machine, the data comprising one or more of a header speed, a throw distance, and a header load (see at least paragraph 0203; wherein the merger control system 1100 increases or decrease the speed of the first belt 306 to vary the deposition of the material 114, which achieves a desired or final location of the material 114). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Babler with the teachings as in McKinnis, JR. The motivation for doing so would have been to improve feed quality by running the pickup nearest the discharge at a slower rotational speed than would be necessary if they all ran at the same speed, see Babler paragraph 0010. As per claim 11, Babler discloses wherein the data comprises the throw distance and the throw distance is input by a user through the user input (see at least paragraph 0203; wherein the merger control system 1100 increases or decrease the speed of the first belt 306 to vary the deposition of the material 114, which achieves a desired or final location of the material 114). As per claim 14, McKinnis, JR. does not explicitly mention wherein evaluating the operating conditions comprises considering one or more of a header speed, a throw distance, and a header load. However Babler does disclose: wherein evaluating the operating conditions comprises considering one or more of a header speed, a throw distance, and a header load (see at least paragraph 0203; wherein the merger control system 1100 increases or decrease the speed of the first belt 306 to vary the deposition of the material 114, which achieves a desired or final location of the material 114). Therefore it would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to utilize the teachings as in Babler with the teachings as in McKinnis, JR. The motivation for doing so would have been to improve feed quality by running the pickup nearest the discharge at a slower rotational speed than would be necessary if they all ran at the same speed, see Babler paragraph 0010. Allowable Subject Matter Claim(s) 22 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten to include all of the limitations of the base claim and any intervening claims. The prior art fails to explicitly teach wherein the controller is configured to consider a header speed, a vehicle speed, and a roll gap and the response comprises adjusting one or more of the header speed, vehicle speed, or roll gap. Claim(s) 23 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten to include all of the limitations of the base claim and any intervening claims. The prior art fails to explicitly teach wherein the automatic response comprises modifying each of the operating conditions. Relevant Art The prior art made of record and not relied upon are considered pertinent to applicant’s disclosure: USPGPub 2025/0127078 – Provides a header and a crop merger for a work machine, and in particular to controlling the raising and lowering of the header and the crop merger. USPGPub 2019/0261554 – Provide a harvesting machine including a controller which is arranged to automatically identify an identity of an agricultural header supported on the harvesting machine, and more particularly, the present invention relates to features on the controller for performing various autonomous actions based on the automatically identified identity of the header.
