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 . Response to Amendment Claims 1-14 have been cancelled. New claims 15-29 are presented for examination. Response to Arguments Applicant's arguments filed on June 12, 2026 have been fully considered but they are not persuasive. The Applicant argued that XUE fails to disclose or suggest “a plurality of S-SSBs that are transmitted based on a the number of the plurality of S-SSBs and frequency domain off set value between the neighboring S-SSBs in the frequency domain.” In response, the Examiner respectfully disagrees because XUE discloses the transmission of S-SSBs to other UEs, frequency offset value associated with S-SSB and each S-SSB occupies 11 resource blocks (Section 0073, 0084, 0100, 0102,109, 0153). Moreover, the Examiner has made a new ground of rejection. The new ground of rejection does not mean acquiescing with the Applicant’s stated arguments. 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. 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. 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. Claims 15-29 are rejected under 35 U.S.C. 103 as being unpatentable over HWANG et al (US 2023/0421235 A1, Foreign Priority: November 3, 2020) in view of 2023/0354311 A1). Regarding claim 15 (New), HWANG ‘235 discloses a method by a first terminal (see, the transmitting UE, transmits a number of S-SSBs to a receiving UE within one S-SSB transmission duration, section 0115, 0116-0117, fig. 11, UE 1 coupled to UE 2 in sidelink configuration) in a communication system (fig. 1, the UE and the gNB in the 5G wireless system, section 0051, noted: fig. 11 to fig. 13, SL communication system in which a UE communicated with neighboring UEs, section 0133, 0135-0140, 0146), the method (see ,the receiving UE receives S-SSBs from a transmitting UE, section 0115-0116, 0117) comprising: identifying a number of plurality of sidelink synchronization signal blocks (S- SSBs) (see, the receiving UE searches from the transmitted signals (i.e., discovery signals relating SL-SSBs, section 0166) , section 0144-0148), identifying a offset value in frequency domain (see, offset value form a slot, section 0172, 0206). HWANG ‘235 discloses all the claim limitations but fails to explicitly disclose: identifying a offset value in frequency domain between neighboring S-SSBs, transmitting the plurality of S-SSBs based on the number of the plurality of S- SSBs and the offset value between neighboring S-SSBs in frequency domain. XUE ‘311 from a similar field of endeavor discloses: identifying a offset value (see, offset from a lowest frequency, section 0153, noted: S-SSB which occupies 11 RBs with an offset of 4.5 from the low frequency edge, 0084, 0100) in frequency domain between neighboring S-SSBs (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073), transmitting the plurality of S-SSBs based on the number of the plurality of S- SSBs and the offset value between neighboring S-SSBs in frequency domain (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073). In view of the above, it 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 to implement the SL method and system where the receiving UE or UEs communicate with other UEs based S-SSBs of XUE ‘311 into the SL communication method and apparatus where the transmitting UE/receiving UE each communicates with each other using the best transmission beam/reception beam (section 150) of HWANG ‘235. The motivation would have been to provide resource efficiency and a reduction in latency. Regarding claim 16 (New), HWANG et al (US 2023/0421235 A1, Foreign Priority: November 3, 2020) discloses method of claim 15, wherein a number of resource blocks for an S-SSB among the plurality of S- SSBs is 11 (see, the bandwidth of the S-SSB my be 11 resource blocks, section 0114, see, number of S-SSBs that the transmitting UE transmits to a receiving UE, section 0115-0116, 0166). Regarding claim 17 (New), HWANG ‘235 discloses the method of claim 15, wherein the plurality of S-SSBs (see, number of S-SSBs that the transmitting UE transmits to a receiving UE, section 0115-01160 are transmitted in the same slot (see, the S-SSB may have the same numerology, section 0114, 0142, 0172-same beam in slot). Regarding claim 18 (New), HWANG ‘235 discloses the method of claim 15, wherein information of master information block (MIB) included in the plurality of S-SSBs are same (section 0089, MIB, see, broadcast of S-SSBs, section 0113-0114, 0122, 0133, 0146). Regarding claim 19 (New), HWANG ‘235 discloses a method (see ,the receiving UE receives S-SSBs from a transmitting UE, section 0115-0116, 0117) by a second terminal (see, the transmitting UE, transmits a number of S-SSBs to a receiving UE within one S-SSB transmission duration, section 0115, 0116-0117) in a communication system (fig. 1, the UE and the gNB in the 5G wireless system, section 0051, noted: fig. 11 to fig. 13, SL communication system in which a UE communicated with neighboring UEs, section 0133, 0135-0140, 0146), the method (see ,the receiving UE receives S-SSBs from a transmitting UE, section 0115-0116, 0117) comprising: identifying a number of plurality of sidelink synchronization signal blocks (S- SSBs) (see, the receiving UE searches from the transmitted signals (i.e., discovery signals relating SL-SSBs, section 0166) , section 0144-0148), identifying a offset value in frequency domain (see, offset value form a slot, section 0172, 0206) [[between neighboring S-SSBs, receiving the plurality of S-SSBs based on the number of the plurality of S- SSBs and the offset value between neighboring S-SSBs in frequency domain]]. HWANG ‘235 discloses all the claim limitations but fails to explicitly disclose: identifying a offset value in frequency domain between neighboring S-SSBs, transmitting the plurality of S-SSBs based on the number of the plurality of S- SSBs and the offset value between neighboring S-SSBs in frequency domain. XUE ‘311 from a similar field of endeavor discloses: identifying a offset value (see, offset from a lowest frequency, section 0153, noted: S-SSB which occupies 11 RBs with an offset of 4.5 from the low frequency edge, 0084, 0100) in frequency domain between neighboring S-SSBs (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073), transmitting the plurality of S-SSBs based on the number of the plurality of S- SSBs and the offset value between neighboring S-SSBs in frequency domain (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073). In view of the above, it 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 to implement the SL method and system where the receiving UE or UEs communicate with other UEs based S-SSBs of XUE ‘311 into the SL communication method and apparatus where the transmitting UE/receiving UE each communicates with each other using the best transmission beam/reception beam (section 150) of HWANG ‘235. The motivation would have been to provide resource efficiency and a reduction in latency. Regarding claim 20 (New), HWANG ‘235 discloses the method of claim 19, wherein a number of resource blocks for an S-SSB among the plurality of S-SSBs is 11 (see, the bandwidth of the S-SSB may be 11 resource blocks, section 0114, see, number of S-SSBs that the transmitting UE transmits to a receiving UE, section 0115-0116, 0166). Regarding claim 21 (New), HWANG ‘235 discloses the method of claim 19, wherein the plurality of S-SSBs (see, the bandwidth of the S-SSB may be 11 resource blocks, section 0114, see, number of S-SSBs that the transmitting UE transmits to a receiving UE, section 0115-0116, 0166) are received in the same slot (see, the S-SSB may have the same numerology, section 0114, 0142, 0172-same beam in slot). Regarding claim 22 (New), HWANG ‘235 discloses the method of claim 19, wherein information of master information block (MIB) included in the plurality of S-SSBs are same (section 0089, MIB, see, broadcast of S-SSBs, section 0113-0114, 0122, 0133, 0146). Regarding claim 23 (New), HWANG ‘235 discloses a first terminal (fig. 1, first deice /UE 100 which comprises processor coupled to a transceiver 106 and memory 104, section 0216-022, see, the transmitting UE, transmits a number of S-SSBs to a receiving UE, section 0115-0117, fig. 11, UE 1 coupled to UE 2 in sidelink configuration)) in a communication system, the first terminal comprising: a transceiver (fig. 1, first deice /UE 100 which comprises processor coupled to a transceiver 106 and memory 104, section 0216-022); and a controller configured (fig. 23, processor 102 which controls the memory and the transceiver, section 0216-0222) to: identify a number of plurality of sidelink synchronization signal blocks (S-SSBs) (see, see, the transmitting UE, transmits a number of S-SSBs to a receiving UE, section 0115-0117, noted: the transmitting UE implicitly identifying the S-SSB by virtue improve the S-SSB reception performance of the receiving UE, section 0126, moreover, the act of transmitting a discovery signal in relation to a number of S-SSBs, section 0165-0166), identify a offset value in frequency domain (see, offset value form a slot, section 0172, 0206) [[between neighboring S- SSBs, transmit the plurality of S-SSBs based on the number of the plurality of S-SSBs and the offset value between neighboring S-SSBs in frequency domain]]. HWANG ‘235 fails to explicitly disclose: identify a offset value in frequency domain between neighboring S- SSBs, transmit the plurality of S-SSBs based on the number of the plurality of S-SSBs and the offset value between neighboring S-SSBs in frequency domain. XUE ‘311 from a similar field of endeavor discloses: identify a offset value (see, offset from a lowest frequency, section 0153, noted: S-SSB which occupies 11 RBs with an offset of 4.5 from the low frequency edge, 0084, 0100, see, the BS configures sidelink UE, the sidelink sync UE may broadcast S-SSBs to other UEs, section 0073) in frequency domain between neighboring S-SSBs (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073), transmit the plurality of S-SSBs based on the number of the plurality of S- SSBs (section 0073-based on signal received from the station, the sidelink sync broadcasts S-SSBs to pother UEs) and the offset value between neighboring S-SSBs in frequency domain (see, the receiving UE or UEs are aware of S-SSB transmission in a slots, section 0102, 0109, the receiving UE or UEs communicate with each other based on S-SSBs, section 0073, noted: S-SSB which occupies 11 RBs with an offset of 4.5 from the low frequency edge implies transmitting and reception based on the said offset, 0084 ). In view of the above, it 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 to implement the SL method and system where the receiving UE or UEs communicate with other UEs based S-SSBs of XUE ‘311 into the SL communication method and apparatus where the transmitting UE/receiving UE each communicates with each other using the best transmission beam/reception beam (section 150) of HWANG ‘235.
