Office Action

§102 §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 . Response to Remarks This Office action is considered fully responsive to the amendments filed 01/27/2026. The previous objection to the drawings is withdrawn in light of Applicant’s remarks (page 6, Remarks, 01/27/2026). Response to Arguments Applicant's arguments filed 01/27/2026 have been fully considered but they are not persuasive. Applicant argues: Rahman discloses that a periodicity and slot offset of SRS burst transmissions are configured by the periodicityAndOffset parameter. A UE receives a MAC CE and/or DCI based activation signal and transmits the SRS bursts according to the periodicityAndOffset. However, Rahman is completely silent on determining a configuration of the SRS burst according to the activation/deactivation signal. Therefore, Applicants assert that Rahman fails to disclose, at least, "determin[ing] a sensing signal burst configuration based on the MAC-CE message, the sensing signal burst configuration including at least one of a burst periodicity or a burst length of a sensing signal burst," as required by independent claim 1 (page 9, Remarks). Examiner respectfully disagrees. Examiner notes the claim limitation “determin[ing] a sensing signal burst configuration based on the MAC-CE message, the sensing signal burst configuration including at least one of a burst periodicity or a burst length of a sensing signal burst," does not require the configuration of a sensing signal burst to be done by the MAC-CE message, rather it is just based upon a MAC-CE message, the context of which is not specified. A valid interpretation is that the MAC-CE being received at the UE triggers a configuration by the UE. Therefore, “the sensing signal burst configuration including at least one of a burst periodicity or a burst length of a sensing signal burst” does not need to be configured by the MAC-CE, rather just based upon the MAC-CE in any context. As Examiner cited, para. 0299 of Saifur Rahman discloses “The UE is configured to transmit an SRS burst based on a MAC CE or/and DCI based activation or/and deactivation of a SP SRS resource. The periodicity and the slot offset of an activated SP SRS resource is configured via higher layer parameter periodicityAndOffset-sp.” Therefore, based on the MAC-CE being transmitted to the UE, the UE configures an SRS burst transmission, and the periodicity and slot offset pertaining to this SRS burst are also configured. Applicant argues: Claims 10 and 19 are rejected under 35 U.S.C. 103 as allegedly being unpatentable over Rahman in view of US 2016/0227458 Al (Lee). Applicants traverse this rejection for the reasons below (page 10, Remarks). Examiner respectfully disagrees. No reasons have been given by Applicant. All rejections are maintained. Claim Rejections - 35 USC § 102 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. 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) 1-9, 11-18, 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Publication No. 2022/0295499 A1 to Rahman et al. (“Saifur Rahman”) [provided by Applicant].

Claim Rejections - 35 USC § 103 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. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claim(s) 10, 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Publication No. 2022/0295499 A1 to Rahman et al. (“Saifur Rahman”) [provided by Applicant] in view of U.S. Publication No. 2016/0227458 A1 to Lee et al. (“Lee”). As to claim 10, Saifur Rahman does not expressly disclose the apparatus of claim 9, wherein the at least one memory stores instructions that, when executed by the at least one processor, cause the apparatus to determine a speed of an object based on the Doppler shift. Lee discloses at fig. 13, para. 0029, para. 0113, block 1302 may include computing a Doppler shift [by a network entity] of a SRS transmitted by the UE and determining the speed of the UE as a function of the Doppler shift. Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the determination as taught by Lee into the invention of Saifur Rahman. The suggestion/motivation would have been to serve cell change management (Lee, para. 0001). Including the determination as taught by Lee into the invention of Saifur Rahman was within the ordinary ability of one of ordinary skill in the art based on the teachings of Lee. As to claim 19, Saifur Rahman does not expressly disclose the apparatus of claim 16, wherein the at least one memory stores instructions that, when executed by the at least one processor, cause the apparatus to determine a speed of an object based on the Doppler shift. Lee discloses at fig. 13, para. 0029, para. 0113, block 1302 may include computing a Doppler shift [by a network entity] of a SRS transmitted by the UE and determining the speed of the UE as a function of the Doppler shift. Prior to the effective filing date of invention, it would have been obvious to a person of ordinary skill in the art to incorporate the determination as taught by Lee into the invention of Saifur Rahman. The suggestion/motivation would have been to serve cell change management (Lee, para. 0001). Including the determination as taught by Lee into the invention of Saifur Rahman was within the ordinary ability of one of ordinary skill in the art based on the teachings of Lee. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
