Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Amendment This action is in response to amendments and remarks filed on 10/08/2025. The examiner notes the following adjustments to the claims by the applicant: Claims 1, 2, 7-10, 12-14, and 16-20 are amended; No claims are cancelled or added. Therefore, Claims 1-20 are pending examination, in which Claims 1, 8 and 14 are independent claims. In light of the instant amendments and arguments: Further examination resulted in a new rejection of Claims 1-20 under 35 U.S.C. § 103, as detailed below. THIS ACTION IS MADE FINAL. Necessitated by amendment. Response to Arguments Applicant presents the following arguments regarding the previous office action: To overcome the 35 U.S.C. § 103 rejection, the applicant has amended each independent claim to include the additional underlined limitations: "wherein the first parameter comprises an enable detection parameter that turns obstacle detection functionality for the material handling vehicle on or off"; “Amended claim 1 recites "determine a first parameter for operating the material handling vehicle based on a zone within the facility associated with the location, wherein the first parameter comprises an enable detection parameter that turns obstacle detection functionality for the material handling vehicle on or off' and "control operation of the material handling vehicle in accordance with the first parameter" (emphasis added). Estep, Medwin, and Bohler, alone or in combination, fail to teach or suggest at least these features recited in claim 1.”; “Bohler describes how functionality related to an obstacle detection device can be changed based on a particular mode that a transport system is operating in. For example, Bohler notes that the obstacle recognition device can deactivate the monitored field generated by the obstacle recognition device when the transport system is operating in the placement operating mode, at least until the transport system places a pallet or pallet cage on a free placement area. However, Bohler does not teach or suggest changing the functionality of the obstacle recognition device based on particular zone within a facility in which the material handing vehicle is located.”. Applicant's arguments A., B. and C. appear to be directed to the instantly amended subject matter. Accordingly, they have been addressed in the rejections below. 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. Claims 1-6, 8-9, 11, 13-16 and 19 are rejected under 35 U.S.C. §103 as being unpatentable over the combination of Estep et al. (US 12,066,841 B2, henceforth Estep), Hagvall et al. (US 2025/0249894 A1, henceforth Hagvall) and Medwin et al. (US 9,650,233 B2), henceforth Medwin. Regarding Claim 1, Estep recites the limitations: a material handling vehicle {10, Figs. 1, 6 & 11}, comprising: a sensor for gathering data associated with the material handling vehicle {“materials handling vehicles in an industrial environment may include utilizing ultra-wideband (UWB) antenna array systems respectively mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles”, Abstract}; and a controller comprising circuitry {“vehicular processors such as processors 104 communicatively coupled to the vehicle 100. The one or more processors 104 can execute machine readable instructions to implement any of the methods or functions described herein automatically. Memory 106 for storing machine readable instructions can be communicatively coupled to the one or more processors 104, the vehicle 100, or any combination thereof.”, Col. 7, Lns. 39-47; and 202, 216 and 217 in Fig. 2} configured to: determine a location of the material handling vehicle within a facility using the data from the sensor {multiple sensor options with the primary sensor being ultra-wideband antenna based: “a camera, laser based system, and/or UWB based system 150 can be mounted to an industrial vehicle (e.g., automated guided vehicle or a manually guided vehicle) that navigates through a warehouse and can assist with vehicle localization. The laser based system may include a laser scanner, a laser rangefinder, a 2D/3D mapping laser, a lidar, or combinations thereof…the UWB systems described herein may be employed semi-autonomous or fully autonomous automation as a primary or secondary safety system working alongside the lidar and/or image sensors”, Col. 6, Lns. 35-48}; determine a first parameter for operating the material handling vehicle ; determine a second parameter for operating the material handling vehicle; and control operation of the material handling vehicle in accordance with the first parameter and the second parameter {control of robot determined by multiple parameters such as pose, speed and acceleration: “the UWB system 160 may be used as a sensor system for enforcing speed limits and/or halting vehicle movements in hazardous conditions when the UWB system 160 detects two or more vehicles 100 are operating too close to one-another. The UWB system 160 may thus detect the full relative pose of one vehicle 100 to a high degree of accuracy and read other information from another vehicle 100 in order to determine if the pair of vehicles 100 are in a hazardous scenario with respect to one another and to take a preventative action accordingly (e.g., stopping, slowing, turning, automatic braking, active cruise control, or other collision avoidance action).”, Col. 15, Lns. 29-39}. Estep does not appear to explicitly recite the limitation: wherein the first parameter comprises an enable detection parameter that turns obstacle detection functionality for the material handling vehicle on or off; and operating the material handling vehicle based on a zone within the facility associated with the location. However, Hagvall explicitly recites the limitation: wherein the first parameter comprises an enable detection parameter that turns obstacle detection functionality for the material handling vehicle on or off {“allowing less strict safety requirements, e.g. as in Action 202 above, may comprise one or more out of: Increase/change a speed limit.

The combination of Estep and Hagvall and does not appear to explicitly recite the limitation: operating the material handling vehicle based on a zone within the facility associated with the location. However, Medwin explicitly recites the limitation: operating the material handling vehicle based on a zone within the facility associated with the location {operating vehicle in restricted versus non-restricted zones: “drive the industrial vehicle 10 into the restricted area, room 160, that event causes the location control routine 140 to branch to step 156. At this time, the vehicle controller 12 disables further operation of industrial vehicle 10…Instead of entirely disabling operation, the vehicle controller 12 could severely limit the operation, such as by limiting the speed of travel to an extremely slow maximum level or disabling only some functions.”, Col. 15, Lns. 12-23}. The combination of references Estep, Hagvall and Medwin are analogous art because they deal with operating autonomous vehicles in a warehouse environment. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, having the teachings of Estep, Hagvall and Medwin before them, to modify the teachings of Estep and Hagvall to include the teachings of Medwin to safely operate an industrial vehicle in an environment with varying storage conditions {Col. 1, Lns. 56-64}.

The minimum distance may be based on a size of the obstacle, a type or classification of the obstacle, a speed of the vehicle, a size of the vehicle, a load carried by the vehicle, and/or a task assigned to the vehicle, among other factors.”, Col. 5, Lns. 47-55}.
