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 . Claim Status Claims 4, 6-7 have been canceled. Claims 1, 3, 5, and 8-20 are pending in the application and have been examined. Response to Arguments Applicant's arguments filed 4/6/2026 have been fully considered but they are not persuasive. Applicant argues in the Remarks: (Claim 1) Windeler does not teach or suggest: “determine a plurality of available view paths … associated with the vehicle sensor suite.” Examiner respectfully disagrees. Windeler determines the variety of view paths via the available camera angles located at different pillars, much the same way the instant application determines available view paths based on the available sensors located in different positions. (Claim 1) Windeler does not teach or suggest “determine a vehicle trajectory and a desired field of view … based on … the driver's head movement or the driver's eye movement,” and does not teach or suggest “select an optimal view path from the plurality of available view paths, based on the vehicle trajectory and the desired field of view.” Examiner notes that it appears the Applicant modified the claim limitations in the arguments and that the full limitations are, “determine a vehicle trajectory and a desired field of view responsive to determining that the driver's field of view is obstructed, wherein the desired field of view is determined based on at least one of the driver's head movement or the driver's eye movement; select an optimal view path from the plurality of available view paths, based on the vehicle trajectory and the desired field of view. It appears that Windeler is not relied upon to teach the contested limitations. See the rejection below or Nix (US 2019/0164430 A1), specifically, ¶55. (Claim 1) Windeler does not teach or suggest, “select the vehicle sensor from the vehicle sensor suite based on the selection of the optimal view path,” and Windeler’s DMS tracks gaze to determine where the driver is looking – not to determine a desired field of view; does not evaluate multiple view paths or consider vehicle trajectory. Examiner disagrees as Windeler has multiple sensors facing in different directions and evaluates head movements to determine which view path is optimal. Further, a person of ordinary skill in the art would recognize that the direction the driver is looking would be the desired field of view, otherwise the driver would not be looking in that direction. Examiner recommends amending the claims to recite something along the lines of a suggested field of view rather than desired field of view which appears to be more in line with what the application is trying to claim. Please note any amendments must be fully supported by the specification. (Claim 5) Yoshizaki does not teach determining a plurality of available view paths comprising an interior camera vision based view path, an exterior camera vision based view path, and a radar sensor or lidar sensor based view path. Examiner respectfully disagrees, the sensors of Yoshizaki is merely relied upon to teach the types of sensors available and modifying the base structure of Windeler in view of Nix. Further, the way the claim limitation is written only a LIDAR system is required since the claim states, “an interior camera vision based view path, an exterior camera vision based view path, and a radar sensor OR lidar sensor based view path.” (emphasis added) Therefore either the system can have interior/exterior cameras and a radar in one embodiment or a LIDAR in a separate embodiment. (Claim 11) Yoshizaki does not disclose, “user inputs indicating that the driver’s field of view is obstructed” Examiner respectfully disagrees as the user input of Yoshizaki could reasonably be interpreted as an action a user would perform when their view is obstructed. 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. Claim(s) 1, 3, 10, 12, and 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Windeler (US 2022/0363194 A1) hereinafter Windeler and Nix (US 2019/0164430 A1) hereinafter Nix. Claim 1: Windeler discloses a vehicle comprising: an image-based detection unit configured to capture first inputs associated with a driver’s field of view [Item 18; ¶14; the driver's head and eye direction is an input associated with the driver's field of view]; a vehicle sensor suite configured to capture second inputs associated with a geographical area that is obstructed from the driver field of view [Items 12, 24; ¶¶10, 12, 15]; a processor communicatively coupled with the detection unit and the vehicle sensor suite, wherein the processor is configured to: obtain the first inputs from the image-based detection unit; determine that a driver is distressed or a driver movement is greater than a predefined movement threshold based on the first inputs; determine that the driver’s field of view is obstructed responsive to determining that the driver is distressed or the driver movement is greater than the predefined movement threshold [¶14; the driver's head in a specific position is associated with being distressed and the view must be obstructed because they are looking directly at the a-pillar]; obtain the second inputs associated with the geographical area from a vehicle sensor associated with the vehicle sensor suite, responsive to determining that the driver’s field of view is obstructed, wherein the second inputs comprise real-time images of the geographical area [¶¶11-15]; and wherein to obtain the second inputs the processor is configured to: determine a plurality of available view paths to capture the second inputs associated with the geographical area, wherein the plurality of available view paths are associated with the vehicle sensor suite [¶¶12-14]; wherein the desired field of view is determined based on at least one of the driver's head movement or the driver's eye movement [¶¶12-14]; select the vehicle sensor from the vehicle sensor suite based on the selection of the optimal view path [¶¶12-14]; output the real-time images on a display screen in the vehicle [¶¶11-15].
