WEED and WILLIAM N. WAGGENER ____________ Appeal 2021-000290 Application 15/719,189 Technology Center 3600 ____________ Before STEFAN STAICOVICI, EDWARD A. BROWN, and MICHAEL J. FITZPATRICK, Administrative Patent Judges. BROWN, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellant1 seeks review under 35 U.S.C. § 134(a) of the Examiner’s decision rejecting claims 1–5, 7–13, and 15–19, which are the pending claims. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies L3 Technologies, Inc., as the real party in interest. Appeal Br. 2. Appeal 2021-000290 Application 15/719,189 2 CLAIMS Claims 1, 9, and 17 are independent. Claim 1 is reproduced below. 1. A method, comprising: determining a current position of a vehicle; comparing the current position of the vehicle to a position-reporting mask; determining a frequency of reporting the position of the vehicle based on the comparison to the mask; and reporting the position of the vehicle at the determined frequency. Appeal Br. 11 (Claims App.). REJECTION Claims 1–5, 7–13, and 15–19 are rejected under 35 U.S.C. § 103 as being unpatentable over Baker (US 2013/0297103 A1, published Nov. 7, 2013) and Gong (US 2018/0068567 A1, published Mar. 8, 2018). ANALYSIS In rejecting claim 1, the Examiner finds that Baker discloses “determin[ing] a current position of a vehicle” (citing Baker ¶¶ 31–39), “determining a frequency of reporting the position of the vehicle based on bandwidth resources” (citing Baker ¶ 33), and “reporting the position of the vehicle at the determined frequency” (citing Baker ¶ 44). Final Act. 3–4 (emphasis added). The Examiner also finds that Baker teaches or suggests that “the transmission frequency protocol may be based on the current location of a vehicle.” Advisory Act. (dated March 5, 2020) (citing Baker ¶¶ 33, 44). The Examiner concedes that Baker does not disclose “comparing a position to a reporting mask.” Final Act. 4. To address this omission, the Appeal 2021-000290 Application 15/719,189 3 Examiner relies on Gong as teaching “an unmanned aerial vehicle authentication system that compares the current position of the vehicle to a position-reporting mask . . . where the restricted area corresponds to the reporting mask)” and “report[ing] the position of the vehicle conditionally based on the comparison to the mask.” Id. at 4–5 (citing Gong ¶¶ 725–34) (bold face omitted, emphasis added). The Examiner concludes that it would have been obvious to one of ordinary skill in the art to combine these teachings of Gong with Baker “to improve flight safety.” Id. at 5 (citing Gong ¶ 5). Appellant contends that neither Baker nor Gong teaches or suggests “determining a frequency of reporting the position of the vehicle based on [‘comparing the current position of the vehicle to a position-reporting mask’].” Appeal Br. 6 (bold face omitted). First, Appellant contends that paragraph 33 of Baker discloses that “the frequency of transmission of the flight positioning information is based on characteristics, such as altitude, airspeed, turn rate, and proximity to a destination, which are associated with, but not the same as the position of the aircraft.” Id. at 7. Appellant further contends that these characteristics instead “determine the likelihood of whether the track of the aircraft will change” and “are used to determine the frequency of transmission of the flight positioning information,” where “more frequent transmission of this information is desired at times when the track of the aircraft is more likely to change.” Id. Second, Appellant contends that paragraph 44 of Baker describes that “the frequency of transmission of the flight positioning information may be based on the ‘state’ of the aircraft, such as whether it is in a ‘cruising’ state or a ‘holding pattern’ state.” Id. at 8. Appellant submits that a “state” may be associated Appeal 2021-000290 Application 15/719,189 4 with, but is not the same as, the aircraft position. Id. Third, Appellant contends that Baker does not mention a mask. Id. Fourth, Appellant contends that Gong fails to remedy the deficiencies of Baker. Appeal Br. 8–9. Appellant asserts that Gong describes that flight regulations may include restrictions on operations of an unmanned aerial vehicle (UAV) that may be applied within geo-fencing boundaries, and may include restrictions on: transmitting data from sensors, wireless signals, and communications. Appeal Br. 8–9 (citing Gong ¶ 725). Appellant’s contentions are unpersuasive. The Examiner correctly points out that Baker discloses the use of Global positioning satellites operating in conjunction with the global positioning system (GPS) to provide signals that are used in determining an accurate position of aircraft by their on-board GPS receivers. Ans. 3 (citing Baker ¶ 31). Baker also discloses determining the frequency of reporting “updated flight positioning information.” See Baker ¶ 33. This can be “determined based upon at least one characteristic of the flight associated with the positional information,” such as the aircraft’s altitude and “proximity to its destination.” Id. According to Appellant: the altitude of an aircraft is related to its position, but is not, itself, a position – an aircraft at a given altitude (or airspeed, turn rate, or proximity to destination) may be at any one of a multitude of positions. None of the altitude, airspeed, turn rate, and proximity to a destination is itself a position or, even together, determines a position of an aircraft. Appeal Br. 7 (emphasis added). However, this assertion overlooks the fact that Baker discloses determining “an accurate position of aircraft.” See Baker ¶ 31. A skilled artisan could readily use this positional information to determine, for example, the aircraft’s proximity to its destination, which Appeal 2021-000290 Application 15/719,189 5 would have a known location. We note claim 1 does not recite that the “vehicle” is an aircraft, or that the vehicle is airborne. Baker discloses that “when a flight is . . . waiting at a gate, the need for more frequent positional updates is reduced, as its path is either static or at least much more predictable.” Baker ¶ 33 (emphasis added). One skilled in the art would understand that the gate’s location at an airport or other facility would be known. Baker teaches that the rate of positional updates can be based on the aircraft being at such location (i.e., a “characteristic of the flight”). Id. Accordingly, this example supports the Examiner’s position that Baker discloses that “the transmission frequency protocol may be based on the current location of a vehicle.” See Advisory Act. Appellant’s contention that a “state” as disclosed in Baker is not the same as the aircraft position (Appeal Br. 8) also overlooks that Baker discloses determining “an accurate position of aircraft.” See Baker ¶ 31. Moreover, Baker discloses that the “state” may correspond to a “flight characteristic,” as discussed above. See Baker ¶ 44 (“the ‘Cruising” state”). As for the claimed “position-reporting mask,” Appellant does not argue that a “mask” has a particular meaning. In light of the Specification, it appears that a “mask” can correspond to a place where data transmission (reporting) from a vehicle can be suppressed (“reporting should not be done, or should be done less frequently”). See Spec. ¶¶ 16, 18. As explained by the Examiner, the rejection does not rely on Baker for teaching the recited position reporting mask; rather, Gong’s teaching of not permitting wireless communications in a restricted area correlates to the recited position reporting mask. Ans. 4. Appellant does not contest the Examiner’s finding that a “restricted area” as disclosed in Gong is a “reporting mask,” as Appeal 2021-000290 Application 15/719,189 6 claimed, or that Gong discloses “report[ing] the position of the vehicle conditionally based on the comparison to the mask.” Final Act. 4–5. There is no requirement that Baker or Gong, individually, teaches “determining a frequency of reporting the position of the vehicle based on [‘comparing the current position of the vehicle to a position-reporting mask’].” Appeal Br. 6. An Examiner is not required to “seek out precise teachings directed to the specific subject matter of the challenged claim.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Rather, in an obviousness analysis, an Examiner can consider not only the express disclosures of the references, but also the “inferences and creative steps that a person of ordinary skill in the art would employ.” Id. Here, the rejection is based on a combination of teachings, and, consequently, attacking Baker and Gong individually is unpersuasive because it fails to address what the collective information demonstrates a skilled artisan would have known, and how that collective knowledge would have influenced the steps taken by such an artisan. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Furthermore, Appellant does not apprise us of error in the Examiner’s stated rationale for combining the teachings of Gong regarding a “mask” with those of Baker to result in the method as recited in claim 1. For these reasons, we sustain the rejection of claim 1 as unpatentable over Baker and Gong. Appellant contends that independent claims 9 and 17 are patentable for reasons analogous to those argued for claim 1, and that claims 2–5, 7, 8, 10–13, 15, 16, 18, and 19 are patentable based on depending from claim 1, 9, or 17. Appeal Br. 9. Accordingly, we sustain the rejection of claims 2–5, 7–13, and 15–19 for the same reasons as for claim 1.
