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 . 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. Claim Status This action is in response to applicant’s filing on 4/29/2024. Claims 1-20 are pending and considered below. Specification The disclosure is objected to because of the following informalities: As indicated by paragraph [0016] (PGPub) and FIG. 1, UAV is numbered “102” and one or more servers are numbered “104”. In paragraphs [0018-0024], UAV is incorrectly numbered “104”. Appropriate correction is required. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “filter unit” (claims 1-7) is one or more of: HEPA filters; UV light filters; electrostatic filters; washable filters; media filters; spun glass filters; pleated filters; and a filter motor coupled to a Fibonacci spiral and a particulate matter filter, as disclosed in applicant’s specification, paragraphs [0020] and [0026]; FIG. 1, UAV-102, and filter system-114; and FIG. 3, UAV-102, control board-202, Fibonacci spiral-302, motor-304, and particulate matter filter-306. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. 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. Claims 1, 5-11 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Chang et al. (US-2019/0108746-A1, hereinafter Chang) in view of Mohammed et al. (Powering UAV with Deep Q-Network for Air Quality Tracking, Sensors 2022, 22, 6118, 8/16/2022, pp. 1-17, hereinafter Mohammed). Regarding claim 1, Chang discloses: An unmanned aerial vehicle (UAV) comprising: (paragraphs [0026-0040] and FIG. 1, indoor air quality control system-100, fixed detectors-110, first communication interface-112, unmanned vehicle platform-120, second communication interface-122, processing unit-124, mobile detector-126, mobile air cleaning device-128, cloud computing platform-200, and external data source-300); one or more processors (paragraphs [0032-0036]); a memory coupled to the one or more processors (paragraphs [0032-0036]); a filter unit coupled to the one or more processors (paragraph [0036]); and initiate, based on the second particulate matter measurement and the first particulate matter measurement, a filtration process (paragraphs [0033-0038]). Chang does not disclose moving a UAV to a second location that is at a predetermined distance from the first location. However, Mohammed discloses a system for guiding a multi-navigation direction of a UAV utilizing Deep Q-network (DQN) based UAV Pollution Tracking (DUPT), including the following features: wherein the one or more processors are configured to: (3.5.1. Experience Replay Memory and Mini-Batch (ERM); and FIG. 4, ERM architecture in DUPT); determine information about a first location (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5.

DQN-Based UAV Pollution Tracking (DUPT) Methodology; 5. Conclusions; and FIG. 1, DQN UAV agent for tracking unhealthy areas (AQI > 150)). Mohammed teaches that an unmanned aerial vehicle (UAV) should collect Air Quality Index (AQI) factors. When a difference between a current AQI and two previous consecutive AQIs is larger than a threshold, then the UAV should traverse to reach an unhealthy area (5. Conclusions). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the UAV travel pattern of Mohammed into the miniature aircraft which monitors air quality and performs air cleaning when air quality reaches an air pollution warning value of Chang. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path.

Conclusions); and determining a second particulate matter measurement at the third location (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions). Mohammed teaches that an unmanned aerial vehicle (UAV) should collect Air Quality Index (AQI) factors. When a difference between a current AQI and two previous consecutive AQIs is larger than a threshold, then the UAV should traverse to reach an unhealthy area (5. Conclusions). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the UAV travel pattern of Mohammed into the miniature aircraft which monitors air quality and performs air cleaning when air quality reaches an air pollution warning value of Chang. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path.

Claims 16-17 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Dhawan, as applied to claims 14-15 above, and further in view of Mohammed. Regarding claim 16, Dhawan does not disclose moving a UAV to a fourth location that is at a predetermined distance from a median location. However, Mohammed further discloses: moving to a fourth location, wherein the fourth location is at a predetermined distance from the median location in x, y, or z directions (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions); and determining a first particulate matter measurement at the fourth location (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions). Mohammed teaches that an unmanned aerial vehicle (UAV) should collect Air Quality Index (AQI) factors. When a difference between a current AQI and two previous consecutive AQIs is larger than a threshold, then the UAV should traverse to reach an unhealthy area (5. Conclusions). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the UAV travel pattern of Mohammed into the smoke and fire monitoring system which uses a bounding box of Dhawan. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path. Regarding claim 17, Dhawan does not disclose moving a UAV to a second location that is at a predetermined distance from the first location. However, Mohammed further discloses: moving to a fourth location, wherein the fourth location is at a first predetermined distance from the median location (3.

DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions); determining a second particulate matter measurement at the fifth location (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions); and determining that the first particulate matter measurement is higher than the second particulate matter measurement (3. DQN-Based UAV Pollution Tracking (DUPT) Methodology; and 5. Conclusions). Mohammed teaches that an unmanned aerial vehicle (UAV) should collect Air Quality Index (AQI) factors. When a difference between a current AQI and two previous consecutive AQIs is larger than a threshold, then the UAV should traverse to reach an unhealthy area (5. Conclusions). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the UAV travel pattern of Mohammed into the smoke and fire monitoring system which uses a bounding box of Dhawan. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path. Regarding claim 19, Dhawan does not disclose a Gaussian field estimation function. However, Mohammed further discloses: wherein determining the first estimated air quality value includes using a Gaussian field estimation function (Abstract). Mohammed teaches that Deep Q-network (DQN) based UAV Pollution Tracking (DUPT) is evaluated and validated using an air pollution environment generated by a well-known Gaussian distribution and kriging interpolation (Abstract). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the Gaussian distribution of Mohammed into the smoke and fire monitoring system which uses a bounding box of Dhawan. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path. Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Dhawan in view of Mohammed, as applied to claim 17 above, and further in view of Chang. Regarding claim 18, Dhawan in view of Mohammed does not disclose initiating a filtration process. However, Chang further discloses: further comprising initiating a filtration process at the fourth location (paragraphs [0033-0038]). Chang teaches that a miniature aircraft should monitor air quality and perform air cleaning when air quality reaches an air pollution warning value (paragraphs [0028] and [0033-0038]). It would have been obvious for a person of ordinary skill in the art at the time of the effective filing date of the claimed invention to incorporate the air cleaning of Chang into the smoke and fire monitoring system which uses a bounding box of Dhawan in view of Mohammed. A person of ordinary skill would have been motivated to do so, with a reasonable expectation of success, for the purpose of causing the UAV to travel to a position with unhealthy air by intelligently traversing a short path. Allowable Subject Matter Claims 2-4 and 12 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.

While inventors named as applicants in a patent application may prosecute the application pro se, lack of familiarity with patent examination practice and procedure may result in missed opportunities in obtaining optimal protection for the invention disclosed. The inventor(s) may wish to secure the services of a registered patent practitioner to prosecute the application, because the value of a patent is largely dependent upon skilled preparation and prosecution. The Office cannot aid in selecting a patent practitioner. A listing of registered patent practitioners is available at https://oedci.uspto.gov/OEDCI/. Applicants may also obtain a list of registered patent practitioners located in their area by writing to Mail Stop OED, Director of the U.S. Patent and Trademark Office, P.O. Box 1450, Alexandria, VA 22313-1450.
