Office Action

§102 §103
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 This office action is in response to communication filed 5/05/26. Response to Amendment The examiner acknowledges the amendment of claims 1,3,6,8,10,12,16,17, the cancellation of claims 18-20 and the addition of claims 21-23. Response to Arguments In response to applicant’s argument that there is no need to communicate the location of the access device to a user interface of the vehicle or external device, it is the examiner’s position that the reference of Ahmed teaches communicating the location of the vehicle access device (the vehicle communicate the location of the access device to the access device, paragraph 059,089-090). Ahmed teaches the location information is used by the vehicle access device to determine the wait time to transmit its signal (paragraph 090). Ahmed teaches the distant and location determining function of the vehicle is use for implementing passive unlock and starting of the vehicle (paragraph 09). In response to applicant's arguments against the references individually (applicant’s argument regarding reference of Chen), one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). 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) 1-4 and 13 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ahmed US Patent Application Publication 20210402955. Regarding claim 1, Ahmed teaches a method for locating a vehicle access device, the method comprising the steps of: detecting a signal from a vehicle access device with one or more access device sensors, wherein the vehicle access device is a key fob (antenna devices on the vehicle receive signal from the mobile device, paragraph 055,057-058); determining a location of the vehicle access device relative to the one or more access device sensors (paragraph 058); and communicating the location of the vehicle access device (the vehicle communicate the location of the access device to the access device, paragraph 059,089). Regarding claim 2, Ahmed et al. teaches detecting a signal from a vehicle access device is accomplished by either the access device or the one or more access device sensors sending wireless communication and the other of the vehicle access device or the one or more access device sensors receiving wireless communication (paragraph 057-058). Regarding claim 3, Ahmed et al. teaches the wireless communication is one or more of cellular, ultra-wideband (UWB), WiFi, radio, or Bluetooth (paragraph 055). Regarding claim 4, Ahmed teaches the step of determining a location of the vehicle access device relative to one or more access device sensors includes determining the signal strength of a communication between the one or more access device sensors and the vehicle access device (paragraph 079). Regarding claim 13, Ahmed teaches the step of determining a location of the vehicle access device relative to the one or more access device sensors includes determining an elapsed time between sending a communication from either the access device sensor or the vehicle access device and receiving a communication from the other of the access device sensor or the vehicle access device (round trip time is used for location determination, paragraph 074,080).. Claim(s) 17, 21-22 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Fuke et al. US Patent Application Publication 20230101462. Regarding claim 17, Fuke et al. teaches a method for locating a vehicle access device, the method comprising the steps of: detecting a change of one or more conditions (detect locking operation, 094); Sending a communication to the vehicle access device to cause the vehicle access device to output a return communication (paragraph 060); detecting a request to search for a vehicle access device, where the request is initiated by a user of the vehicle (search request is initiated based on operation of door handle, S140, paragraph 110, fig, 9); detecting with an access device sensor a communication from a vehicle access device (paragraph 097), comparing a signal strength of the detected return communication or an elapsed time of communication between the vehicle access device and an access device sensor to a predetermined threshold (paragraph 097); determine an approximate location of the vehicle access device as a function of the signal strength or the elapsed time (paragraph 097,0122) and communicating the approximate location of the vehicle access device to the user (paragraph 097-098, fig.6). Regarding claim 21, Fuke teaches the approximate location includes an indication of whether the vehicle access device is located inside or outside of the vehicle (paragraph 013-014,075-076). Regarding claim 22, Fuke teaches the request is initiated via user interface of the vehicle or via an external device (search request is initiated based on operation of door handle, S140, paragraph 110, fig, 9) 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.
