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. Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Zhang (WO 2024/130598 A1). Regarding claim 6, Lee discloses the apparatus of claim 5, but fails to disclose wherein the first DCI format is a DCI format 4_0. Zhang in the same endeavor discloses wherein the first DCI format is a DCI format 4_0. (Paragraph 81 discloses DCI Format 4_0 I used for MCCH-RNTI in an MBS service) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Zhang’s techniques for formatting DCi, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Zhang’s techniques for formatting DCi, since Zhang states in paragraph 82 that the modification results in allowing the UE to be scheduled for PDSCH broadcast and enable resource-efficient delivery of multicast/broadcast services as further stated in Zhang’s paragraph 2. Claim(s) 11 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Yerramalli (WO 2022147380 A1). Regarding claim 11, Lee discloses the apparatus of claim 10 set forth above, wherein the one or more processors are further configured to execute the computer-executable instructions and cause the apparatus to: Lee further discloses monitor another configured SS for a PDCCH scheduling communication via the multicast MTCH, said monitoring being performed during an RRC connected mode; . (Lee indicates in paragraph 238 that the UE in connected state monitors PDCCH scheduling and also monitors PDSCH scheduling and in paragraph 239 Lee discloses PDSCH Scheduling is received in MTCH) Lee fails to disclose enter the RRC inactive mode, wherein the RRC release message configuring the SS is obtained. Yerramalli discloses enter the RRC inactive mode, wherein the RRC release message configuring the SS is obtained. (See paragraph 132 and Fig. 5 from RRC Connected state of Fig. 5 step 520 transitions to RRC connected inactive 530 when an RRC release message is received. The configuration of the Type2a-PDCCH can be signaled as indicated to the UE in the RRC release message that sets up the RRC INACTIVE state 530 (e.g., the RRC release messages at stages 23.6 and 23.10) See paragraphs 100, 117 123 and 155) . In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Yerramalli ’s techniques for inactive RRC mode SS configuring, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Yerramalli ’s techniques for inactive RRC mode SS configuring, since Yerramalli states in paragraph 117 that the modification results in allowing benefits to the network of INACTIVE state positioning include faster UE transitions to the CONNECTED state since the network maintains the UE's context (e.g., network identifiers, radio bearers, etc.) while it is in the INACTIVE state. Benefits to the UE also include faster transitions to the CONNECTED state and in addition, decreased power consumption, as the UE is only monitoring for pages when in the INACTIVE state. Regarding claim 12, Lee discloses the apparatus of claim 10 set forth above, wherein the one or more processors are further configured to execute the computer-executable instructions and cause the apparatus to: Lee further discloses monitor another configured SS for a PDCCH scheduling communication via the multicast MTCH, said monitoring being performed during an RRC connected mode; . (Lee indicates in paragraph 238 that the UE in connected state monitors PDCCH scheduling and also monitors PDSCH scheduling and in paragraph 239 Lee discloses PDSCH Scheduling is received in MTCH) Lee fails to disclose enter the RRC inactive mode, wherein the monitoring comprises continuing to monitor in the other SS for the PDCCH scheduling the multicast MTCH until the SIB is obtained. Yerramalli discloses enter the RRC inactive mode, wherein the monitoring comprises continuing to monitor in the other SS for the PDCCH scheduling the multicast MTCH until the SIB is obtained. (Per paragraph 132 states a cell-specific Type2a-PDCCH search space can be configured that a UE can monitor while in the RRC INACTIVE state 530. The configuration of the Type2a-PDCCH can be signaled in (1) an existing SIB (e.g., a PDCCH configuration common in remaining minimum system information (RMSI) or positioning SIBs (Pos-SIBs)), (2) a new SIB defined for this purpose) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Yerramalli ’s techniques for inactive RRC mode SS configuring, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Yerramalli ’s techniques for inactive RRC mode SS configuring, since Yerramalli states in paragraph 117 that the modification results in allowing benefits to the network of INACTIVE state positioning include faster UE transitions to the CONNECTED state since the network maintains the UE's context (e.g., network identifiers, radio bearers, etc.) while it is in the INACTIVE state. Benefits to the UE also include faster transitions to the CONNECTED state and in addition, decreased power consumption, as the UE is only monitoring for pages when in the INACTIVE state. Claim(s) 13, 15, 17 and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Li (WO 2022218326 A1). Regarding claim 13, Lee discloses the apparatus of claim 7, wherein the monitoring comprises monitoring in a Type0-PDCCH common SS (CSS) or a TypeOB-PDCCH CSS via the multicast MTCH (See Lee’s Table 3 Type0-PDCCH common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166 and DCI formats taught in table 4) However, Lee fails to disclose for a second downlink control information (DCI) format scheduling communication for Type0-PDCCH. Li discloses for a second downlink control information (DCI) format scheduling communication for Type0-PDCCH. (See paragraph 55 Type 0 PDCCH with second or different DCI format. See also paragraph 125) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Li s techniques allocating a candidate PDCCH via formatting DCI, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Li s techniques allocating a candidate PDCCH via formatting DCI, since Li states in paragraph 8 that the modification results in allocating candidate PDCCH of different search space sets in a non-connected state. Regarding claim 15, Lee discloses the apparatus of claim 7, wherein the monitoring comprises monitoring in a Type3-PDCCH common SS (CSS) for scheduling communication via the multicast MTCH. (See table 3 Type 3-PDCCH Common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166 and DCI formats shown in table 4). However, Lee fails to disclose for a third downlink control information (DCI) format scheduling communication for Type3-PDCCH. Li in the same endeavor discloses a third downlink control information (DCI) format scheduling communication for Type3-PDCCH. (See paragraph 59 Type 3 PDCCH with third or different DCI format like a fifth format. See also paragraph 125) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Li s techniques allocating a candidate PDCCH via formatting DCI, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Li s techniques allocating a candidate PDCCH via formatting DCI, since Li states in paragraph 8 that the modification results in allocating candidate PDCCH of different search space sets in a non-connected state. Regarding claim 17, Lee modified Li discloses the apparatus of claim 15, Lee further discloses wherein the monitoring comprises monitoring at least one of: PDCCH candidates of the defined set of CCE aggregation levels (i.e. Lee ‘s paragraph 114 discloses CCE aggregate levels containing PDCCH candidates being monitored. See tables 7-11 too) or the quantity of one or more PDCCH candidates per CCE aggregation level in a Type3-PDCCH CSS for the PDCCH scheduling communication via the multicast MTCH (alternate limitation need not be addressed being claimed in the alternate. However Lee discloses in paragraph 114 aggregation levels 1, 2, 4, 8 or 16 CCEs with PDCCH candidates . Per paragraphs 119 and 120 the number of PDCCH candidates are defined and monitored. ), said monitoring being performing during the RRC inactive mode.(See Lee paragraphs 236-238 monitoring CSS Type 3 PDCCH when the UE is either in inactive/idle or connected mode) The motivation to combine Lee and Li is set forth above. Regarding claim 18, Lee modified Li discloses the apparatus of claim 15, Lee further discloses wherein the monitoring comprises monitoring unrestricted CCE aggregation levels and an unrestricted number of PDCCH candidates per CCE aggregation level (See Lee in paragraph 114 aggregation levels 1, 2, 4, 8 or 16 CCEs with PDCCH candidates . Per paragraphs 119 and 120 the number of PDCCH candidates are defined. However per paragraph 235 Lee indicates unlimited number of PDCCH candidates can be monitored but to lower Blind Detection (BD) overhead a maximum limit of PDCCH candidates is applied, For Type 3 CSS PDCCH per paragraph 275 it can be prioritized and its limit/restriction increased over all USSs) in a Type3-PDCCH CSS for the PDCCH scheduling communication via the multicast MTCH, (See Lee table 3 Type 3-PDCCH Common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166) said monitoring being performed during the RRC inactive mode. (See Lee paragraphs 236-238 monitoring CSS Type 3 PDCCH when the UE is either in inactive/idle or connected mode. (Lee indicates in paragraph 238 that the UE in inactive state monitors PDCCH scheduling and also monitors PDSCH scheduling and in paragraph 239 Lee discloses PDSCH Scheduling is received in MTCH) The motivation to combine Lee and Li is set forth above. Claim(s) 14 and 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Li and further in view of Yoshioka et al (US 20250175983 A1). Regarding claim 14, Lee modified by Li discloses the apparatus of claim 13 but fails to disclose wherein the second DCI format is a DCI format 4_1 or a DCI format 4_2 for scheduling communication via the multicast MTCH. Yoshioka discloses wherein the second DCI format is a DCI format 4_1 or a DCI format 4_2 for scheduling communication via the multicast MTCH. .( Per paragraph 68 Yoshioka discloses use of DCI format 4_1 or DCI format 4_2 for multicast operation on MCCH and MTCH – see also paragraphs 73, 115, 146 and 147) In view of the above, having Lee’s monitoring Search Space techniques modified by Li s techniques allocating a candidate PDCCH via formatting DCI and then given the well- established teaching of Yoshioka’ s use of DCI format, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to further modify Lee’s monitoring Search Space techniques modified by Li s techniques allocating a candidate PDCCH via formatting DCI as taught by Yoshioka’ s use of DCI format, since Yoshika states in paragraph 68 that the modification results in providing DCI formats for multicast. Regarding claim 16, Lee modified by Li discloses the apparatus of claim 15 but fails to disclose the third DCI format is a DCI format is a DCI format 4_1 for scheduling communication via the multicast MTCH. Yoshioka discloses the third DCI format is a DCI format is a DCI format 4_1 for scheduling communication via the multicast MTCH.( Per paragraph 68 Yoshioka discloses use of DCI format 4_2 for multicast operation on MCCH and MTCH – see also paragraphs 73, 115, 146 and 147) In view of the above, having Lee’s monitoring Search Space techniques modified by Li s techniques allocating a candidate PDCCH via formatting DCI and then given the well- established teaching of Yoshioka’ s use of DCI format, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to further modify Lee’s monitoring Search Space techniques modified by Li s techniques allocating a candidate PDCCH via formatting DCI as taught by Yoshioka’ s use of DCI format, since Yoshika states in paragraph 68 that the modification results in providing DCI formats for multicast. Claim(s) 19-22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Chatterjee et al (US 20190246254 A1). Regarding claim 19, Lee discloses the apparatus of claim 1 including Type3-PDCCH (Table 3) and MCCH and MTCH (paragraph 166), however Lee fails to disclose wherein the monitoring comprises monitoring in a TypeOB—PDCCH common SS (CSS) or a Type3-PDCCH CSS for PDCCHs scheduling communication via a broadcast MBS control channel (MCCH) and a broadcast MBS traffic channel (MTCH). Chatterjee in the same endeavor discloses, wherein the monitoring comprises monitoring in a TypeOB—PDCCH common SS (CSS) or a Type3-PDCCH CSS for PDCCHs scheduling communication via a broadcast MBS control channel (MCCH) and a broadcast MBS traffic channel (MTCH). (Chatterjee literally teaches the limitation in question in paragraphs 45, 63 and 64. In paragraph 45 Type3-CSS for MPDCCH/NPDCCH used for scheduling for downlink channel (i.e. MCCH) is established and in paragraph 63 Chatterjee further establishes SC-MCCH scheduled by MPDCCH/NPDCCH in Type 3-CSS. Further in paragraph 64 Chatterjee discloses Type3-CSS and the associated PDSCH/NPDSCH carrying SC-MCCH and SC-MTCH content, respectively, with other search spaces and downlink channels that the UE may be expected to monitor or receive.) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, since Chatterjee states in paragraph 45 given the broadcast nature of SC-PTM transmissions in a single cell that the modification results in allowing all or a group of UEs within a multicast region (cell ) to monitor the scheduling of the downlink control channel (i.e. the SC-MCCH) using MPDCCH/NPDCCH. Regarding claim 20, Lee modified by Chatterjee discloses the apparatus of claim 19, Lee further disclose wherein the monitoring comprises: monitoring at least one of: the defined set of CCE aggregation levels (i.e. Lee ‘s paragraph 114 discloses CCE aggregate levels containing PDCCH candidates being monitored. See tables 7-11 too) or the quantity of one or more PDCCH candidates per CCE aggregation level for the PDCCH (i.e. See Lee’s paragraphs 119 and 120 indicating the quantity of PDCCH candidates to be monitored) scheduling communication via one of the broadcast MTCH and the broadcast MCCH(See Lee table 3 Type 3-PDCCH Common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166) ; and monitoring unrestricted CCE aggregation levels and unrestricted number of PDCCH candidates per CCE aggregation level for the PDCCH scheduling (See Lee in paragraph 114 aggregation levels 1, 2, 4, 8 or 16 CCEs with PDCCH candidates . Per paragraphs 119 and 120 the number of PDCCH candidates are defined. However per paragraph 235 Lee indicates unlimited number of PDCCH candidates can be monitored but to lower Blind Detection (BD) overhead a maximum limit of PDCCH candidates is applied, For Type 3 CSS PDCCH per paragraph 275 it can be prioritized and its limit/restriction increased over all USSs) communication via the other one of the broadcast MTCH and the broadcast MCCH. (See Lee’s Paragraph 166 on broadcast MCCH and MTCH) The motivation to combine Lee and Chatterjee is set forth above. Regarding claim 21, Lee modified by Chatterjee discloses the apparatus of claim 19, Lee further discloses monitoring at least one of: the defined set of CCE aggregation levels (i.e. Lee ‘s paragraph 114 discloses CCE aggregate levels containing PDCCH candidates being monitored. See tables 7-11 too) or the quantity of one or more PDCCH candidates per CCE aggregation level for the PDCCH (i.e. See Lee’s paragraphs 119 and 120 indicating the quantity of PDCCH candidates to be monitored. See Lee table 3 Type 3-PDCCH Common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166) Lee fails to disclose for both the PDCCH scheduling communication via the broadcast MTCH and the PDCCH scheduling communication via the broadcast MCCH. Chatterjee in the same endeavor discloses, for both the PDCCH scheduling communication via the broadcast MTCH and the PDCCH scheduling communication via the broadcast MCCH. (Chatterjee discloses in paragraph 56 aggregation level of the PDCCH/MPDCCH type 3-CSS. Chatterjee literally teaches the limitation in question in paragraphs 45, 63 and 64. In paragraph 45 Type3-CSS for MPDCCH/NPDCCH used for scheduling for downlink channel (i.e. MCCH) is established and in paragraph 63 Chatterjee further establishes SC-MCCH scheduled by MPDCCH/NPDCCH in Type 3-CSS. Further in paragraph 64 Chatterjee discloses Type3-CSS and the associated PDSCH/NPDSCH carrying SC-MCCH and SC-MTCH content, respectively, with other search spaces and downlink channels that the UE may be expected to monitor or receive.) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, since Chatterjee states in paragraph 45 given the broadcast nature of SC-PTM transmissions in a single cell that the modification results in allowing all or a group of UEs within a multicast region (cell ) to monitor the scheduling of the downlink control channel (i.e. the SC-MCCH) using MPDCCH/NPDCCH. Regarding claim 22, Lee modified by Chatterjee discloses the apparatus of claim 19, Lee further discloses wherein the monitoring comprises monitoring unrestricted CCE aggregation levels and an unrestricted number of PDCCH candidates per CCE aggregation level (See Lee in paragraph 114 aggregation levels 1, 2, 4, 8 or 16 CCEs with PDCCH candidates . Per paragraphs 119 and 120 the number of PDCCH candidates are defined. However per paragraph 235 Lee indicates unlimited number of PDCCH candidates can be monitored but to lower Blind Detection (BD) overhead a maximum limit of PDCCH candidates is applied, For Type 3 CSS PDCCH per paragraph 275 it can be prioritized and its limit/restriction increased over all USSs and Type3-PDCCH CSS for the PDCCH scheduling communication via the multicast MTCH taught -See Lee table 3 Type 3-PDCCH Common SS being monitored and transmitted on PDSCH/MTCH as detailed n paragraph 166) Lee fails to disclose for both the PDCCH scheduling communication via the broadcast MTCH and the PDCCH scheduling communication via the broadcast MCCH. Chatterjee in the same endeavor discloses, for both the PDCCH scheduling communication via the broadcast MTCH and the PDCCH scheduling communication via the broadcast MCCH. (Chatterjee discloses in paragraph 56 aggregation level of the PDCCH/MPDCCH type 3-CSS. Chatterjee literally teaches the limitation in question in paragraphs 45, 63 and 64. In paragraph 45 Type3-CSS for MPDCCH/NPDCCH used for scheduling for downlink channel (i.e. MCCH) is established and in paragraph 63 Chatterjee further establishes SC-MCCH scheduled by MPDCCH/NPDCCH in Type 3-CSS. Further in paragraph 64 Chatterjee discloses Type3-CSS and the associated PDSCH/NPDSCH carrying SC-MCCH and SC-MTCH content, respectively, with other search spaces and downlink channels that the UE may be expected to monitor or receive.) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Chatterjee’s Type3-CSS for MPDCCH/NPDCCH, since Chatterjee states in paragraph 45 given the broadcast nature of SC-PTM transmissions in a single cell that the modification results in allowing all or a group of UEs within a multicast region (cell ) to monitor the scheduling of the downlink control channel (i.e. the SC-MCCH) using MPDCCH/NPDCCH. Claim(s) 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lee in view of Zhang et al (US 20250031276 A1). Regarding claim 23, Lee discloses the apparatus of claim 19 including PDCCH scheduling communication on broadcast MBS channel, MCCH, and PCell but fails to disclose wherein the PDCCH scheduling communication via the broadcast MBS channel is on at least one of a primary cell (PCell) or a secondary cell (Scell) during a radio resource control (RRC) connected mode. Latheef fails to disclose wherein the PDCCH scheduling communication via the broadcast MBS channel is on at least one of a primary cell (PCell) or a secondary cell (Scell) during a radio resource control (RRC) connected mode. (See paragraph 92 narrating while being connected to the PCell receiving PDCCH scheduling on MBS broadcast channel, MCCH, in RRC_Connected mode with the PCell. See also paragraphs 16 and 17 on PDCCH and MCCH ) In view of the above, having Lee’s monitoring Search Space techniques and then given the well- established teaching of Latheef ’s techniques on configuring MBS services for PCell/SCell , it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention was made to modify Lee’s monitoring Search Space techniques as taught by Latheef ’s techniques on configuring MBS services for PCell/SCell, since Latheef states in paragraphs 10 and 13 that the modification results in allowing to deliver MBS service related configuration that facilitate a UE's operation and access to the relevant MBS service and to specify a new SIB carrying frequency-service mapping which is also applicable in a non-MBS cell and ensure cell reselection and service continuity aspects for MBS.
