DETAILED ACTION
1. Claims 1, 2, 5, 6, 13, 16, 17, 20, 21, 75, and 76 have been examined and are pending.
Continued Examination Under 37 CFR 1.114
2. A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/26/2025 has been entered.
Response to Amendment
3. In response to the amendments received in the Office on 12/26/2025, the Office acknowledges the current status of the claims: claims 1, 5, 12, 16, and 20 have been amended, claims 3, 4, 7-12, 14, 15, 18, 19, 22-74, 77, and 78 have been canceled, and no new matter appears to be included. Examiner respectfully notes the amendments received in the Office on 12/26/2025 have been further amended from the claim set received in the Office on 11/26/2025.
Response to Arguments
4. Applicant's arguments filed 12/26/2025 have been fully considered but they are not persuasive. Examiner addresses Applicant’s concerns in the following response. Examiner respectfully notes the amendments received in the Office on 12/26/2025 have been further amended from the claim set received in the Office on 11/26/2025.
Applicant argues Ai does not expressly disclose the features of “the control information of the Multicast service and/or broadcast service having been changed or whether the control information of the Multicast service and/or broadcast service has been changed” (Feature X, as assigned by Applicant) and “resource information of the changed control information of the Multicast service and/or broadcast service that needs to be acquired” (Feature A, as assigned by Applicant; see Remarks, pages 14-18). In support of this Argument, Applicant alleges that the DCI must include indications that both control information and resource information has changed.
Examiner respectfully disagrees. Ai explicitly discloses that the resource information is changed (Ai: [0170-0176] – corresponds to the change notification mechanism including scheduling information, which necessarily corresponds to a resource for carrying the MBS. See also [0095], [0325-0339], [0348], and [0436].), and indications that the control information has changed (Ai: [0171-0173] – corresponds to sending a DCI on PDCCH scrambled with an RNTI indicating a change notification of an SC-MCCH, which includes MBMS service information.).
Applicant argues Ai does not disclose Features B-D and 4B-4E (Remarks, pages 18-19). Examiner notes the se features are recited in the alternative form and are not required to be disclosed by the prior art of record (see below rejection).
Examiner articulates the above in the below rejection, and in further consideration of the amendments received in the Office on 12/26/2025.
Claim Rejections - 35 USC § 112
5. The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
6. Claims 1, 2, 5, 6, 13, 16, 17, 20, 21, 75, and 76 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
a) Claims 1, 2, 5, 6, 13, 16, 17, 20, 21, 75, and 76 recite the limitation a/the “Multicast service and/or broadcast service”. The inclusion of “and/or” renders the claim indefinite since one of ordinary skill in the art is not clearly aware whether or not a broadcast service is required with the multicast service. For purposes of examination, Examiner interprets each iteration of “and/or” to require only alternate forms of language that follow the term “or”.
Claim Rejections - 35 USC § 102
7. 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.
8. 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.
9. Claims 1, 5, 6, 12, 16, 17, 20, 21, 75, and 76 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by United States Patent Application Publication 2020/0137528 A1 to Ai et al. (hereinafter “Ai”).

Interpreted to correspond to the type of MBMS service that is provided, which may be a push type or an abrupt type, as disclosed by Ai in at least [0142-0145]. Ai also discloses the control information may be related to a service parameter including, but not limited to one or more of start time, SAI, and frequency in at least [0123].), and/or:
in a case that the control information resource for indicating the Multicast service and/or broadcast service carries change information, receiving the change information of the control information of the Multicast service and/or broadcast service (alternative or dispositive limitation).
Claim 75, directed to an apparatus embodiment of claim 1, recites similar features as claim 1 (in hybrid form) and is therefore rejected upon the same grounds as claim 1. Please see above rejection of claim 1. Ai discloses a network side device comprising at least a memory, processor, and program in at least Figure 11 and claim 23.
Claim 76, directed to an apparatus embodiment of claim 12, recites similar features as claim 12 (in hybrid form) and is therefore rejected upon the same grounds as claim 12. Please see above rejection of claim 12. Ai discloses a terminal comprising at least a memory, processor, and program in at least Figure 12 and claim 29.
10. Claims 2 and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Ai in view of United States Patent Application Publication 2023/0124420 A1 to Kim et al. (hereinafter “Kim”).
Regarding Claim 2, Ai discloses the method according to claim 1, wherein the configuration information of the Multicast service and/or broadcast service includes at least a TMGI (Ai: [0170], [0185]), but does not expressly disclose one of the following:
a Temporary Mobile Group Identity (TMGI) list;
session ID corresponding to TMGI in the TMGI list;
group RNTI corresponding to the TMGI in the TMGI list;
bandwidth Part (BWP) corresponding to the TMGI in the TMGI list;
subcarrier spacing corresponding to the TMGI in the TMGI list;
a logical channel and/or logical channel group corresponding to the TMGI in the TMGI list;
discontinuous Reception (DRX) configuration corresponding to the TMGI in the TMGI list;
uplink resource configuration fed back by Hybrid Automatic Repeat request (HARQ) corresponding to the TMGI in the TMGI list;
uplink resource configuration reported by channel state information (CSI) corresponding to the TMGI in the TMGI list.
However, the feature of including a TMGI list cannot be considered new or novel in the presence of Kim. Kim is similarly concerned with communication of multicast/broadcast services (Kim: [0007]). Kim discloses configuration information of the Multicast service and/or broadcast service includes at least one of the following:
a Temporary Mobile Group Identity (TMGI) list (Kim: [0008], [0097] – information about MBS includes a TMGI list.);
session ID corresponding to TMGI in the TMGI list (alternative or dispositive limitation);
group RNTI corresponding to the TMGI in the TMGI list (Kim: [0009] – information linked to MBS includes “…a group-radio network temporary identity (G-RNTI) corresponding to a TMGI included in the TMGI list.”);
bandwidth Part (BWP) corresponding to the TMGI in the TMGI list (Kim: [0137] – a BWP corresponds to a G-RNTI.);
subcarrier spacing corresponding to the TMGI in the TMGI list (alternative or dispositive limitation);
a logical channel and/or logical channel group corresponding to the TMGI in the TMGI list (Kim: [0094] – “…the UE 1e-05 may determine an MBS RLC-bearer to deliver a MAC service data unit (SDU), in consideration of a logical channel ID (LCID) of the MAC SDU included in a MAC PDU and the G-RNTI of the MAC PDU.” This information is in consideration of a TMGI of interest.);
discontinuous Reception (DRX) configuration corresponding to the TMGI in the TMGI list (alternative or dispositive limitation);
uplink resource configuration fed back by Hybrid Automatic Repeat request (HARQ) corresponding to the TMGI in the TMGI list (alternative or dispositive limitation);
uplink resource configuration reported by channel state information (CSI) corresponding to the TMGI in the TMGI list (alternative or dispositive limitation).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention (AIA ) to modify the multicast service and/or broadcast service including a TMGI of Ai in view of the multicast service and/or broadcast service including a TMGI of Kim to include a TMGI list for the reasons of seamlessly transferring an active service during a handover (Kim: [0006-0007]).
Claim 13, dependent upon claim 12, recites similar features as claim 2 and is therefore rejected upon the same grounds as claim 2. Please see above rejection of claim 2.
