Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co. , 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) 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 . Claims 6 and 16 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over SILVERMAN et al.US 2024/0187115 Al in view of ALDANA et al US20230168336A1 Regarding claims 6 and 16, SILVERMAN et al.US 2024/0187115 Al discloses all features with respect to claims1 and 2, respectively. SILVERMAN does not disclose wherein a frame exchange check between the initiator and the at least one responder is performed and, based on this check, a distance between the initiator and the at least one responder is determined. ALDANA et al US20230168336A1 discloses wherein a frame exchange check between the initiator and the at least one responder is performed and, based on this check, a distance between the initiator and the at least one responder is determined [0049] -[ 0052] the first device 302 determines the range (or distance) between the first device 302 and the peripheral device 304 based on the TOF. For example, the first device 302 may be configured to compute the range or distance between the first device 302 and the peripheral device 304 by multiplying the TOF and the speed of light (e.g., TOF×c ). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Wang by including wherein a frame exchange check between the initiator and the at least one responder is performed and, based on this check, a distance between the initiator and the at least one responder is determined, as taught by ALDANA , in order to determine the distance between the devices (see ALDANA [0049]-[0052] ).
