Office Action

§102 §103 §112
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 . DETAILED ACTION Information Disclosure Statement The information disclosure statement (IDS) submitted on 6/24/2025 is being considered by the examiner. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 5, 8 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 5 recites the limitation “an object” in at least two instances. It is unclear if these instances are the same or distinct. For purposes of examination these instances will be interpreted as being the same. Claim 8 recites the limitation “a signal”, and “an obstacle” in at least two instances. It is unclear if these instances are the same or distinct. For purposes of examination these instances will be interpreted as being the same. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1, 8, 10-12 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US20240004060A1 (“Tao”). As per claims 1, 11, and 12 Tao teaches the limitations of the vehicle, system, and method: An unmanned aerial vehicle comprising: a body; an obstacle sensor attached to the body; and a controller configured or programmed to: perform an obstacle avoidance function to detect an obstacle based on a signal output from the obstacle sensor and to perform an operation to avoid collision with the obstacle; disable the obstacle avoidance function when a predetermined condition is satisfied; and enable the obstacle avoidance function when the predetermined condition is not satisfied; wherein the predetermined condition includes at least one of: a first condition that a tilt angle of the body is greater than a predetermined angle; a second condition that the unmanned aerial vehicle is in a takeoff operation or a landing operation; or a third condition that an altitude of the body is at or below a predetermined height. (Tao at least the abstract, [0043], [0157], [0158]) Claim 8: wherein the obstacle sensor is configured to output a signal indicating a distance to an object within a measurement range; and the controller is configured or programmed to: determine that an obstacle has been detected if the distance indicated by the signal is less than a threshold value; and set the threshold value based on the tilt angle and the altitude. (Tao at least the abstract, [0043], FIG. 6, [0117-0149]) Claim 10: a distance sensor configured to measure a distance to the object existing below the body as the altitude. (Tao at least the abstract, [0043], FIG. 6) 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 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. Claim(s) 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tao. As per claim 9, Tao teaches the limitations of the invention as described above. Tao teaches the limitations below, substituting calculating the angle sine value as claimed with the cosine value: when the tilt angle is 0 and the altitude is h, the controller is configured or programmed to vary the threshold value according to the value of h/sin 0. (Tao at least [0149]) It would be obvious to one of ordinary skill in the art to substitute calculating a sine value with a cosine value to triangulate angle and height or distance with a reasonable expectation of results. Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tao in view of US20200278679A1 (“Kunzi”). As per claim 3, Tao teaches the limitations of the invention as described above. Tao does not disclose, which Kunzi teaches: wherein the predetermined condition includes the second condition and the third condition, and does not include the first condition. (Kunzi at least [0091]: “prevent the e-bumper controller from erroneously signaling a collision upon detecting the ground during launch or landing…dynamic collision-avoidance system … automatically armed/disarmed depending on the distance, position, altitude, flight time, etc. of the vehicle… a disabled mode…Precision mode may also be designed to allow the UAV to approach to obstacles closer than in performance mode (e.g., about 1 to 10 feet, more preferably about 3-7 feet, or about 4.5 ft.)”) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Tao with the aforementioned limitations taught by Kunzi with a reasonable expectation of success. One of ordinary skill would have been motivated to combine these references in order to allow the UAV to approach obstacles closer (Kunzi [0091]). Claim(s) 5-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tao in view of US20200135037A1 (“Flotte”). As per claim 5, Tao teaches the limitations of the invention as described above. Tao does not disclose, which Flotte teaches: the obstacle sensor is positioned to detect an object located horizontally away from the body when the body is not tilted. (Flotte at least [0108]) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Tao with the aforementioned limitations taught by Flotte with a reasonable expectation of success. One of ordinary skill would have been motivated to combine these references in order to improve the safety of aircraft (Flotte [0235]). As per claim 6, Tao teaches the limitations of the invention as described above. Tao does not disclose, which Flotte teaches: the obstacle sensor includes a laser sensor fixed to the body so as to emit a light beam toward the object located horizontally away from the body when the body is not tilted. (Flotte at least [0108], [0099]) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Tao with the aforementioned limitations taught by Flotte with a reasonable expectation of success. The motivation to combine these references is the same as above in claim 5. As per claim 7, Tao teaches the limitations of the invention as described above. Tao does not disclose, which Flotte teaches: the obstacle sensor includes an imager fixed to the body so as to capture an image of the object located horizontally away from the body when the body is not tilted. (Flotte at least [0108], [0099]) It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine Tao with the aforementioned limitations taught by Flotte with a reasonable expectation of success. The motivation to combine these references is the same as above in claim 5. Allowable Subject Matter Claims 2 and 4 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The prior art is silent on: the predetermined condition includes the first condition and the second condition, and does not include the third condition. the predetermined condition includes all of the first, second, and third conditions.
