DETAILED ACTION
Response to Amendment
This Action is in response to the amendment filed 7/30/2026, for which the corresponding arguments filed on the same date have been entered. Claims 1-10, 16-22 and 31-43 are currently pending in this application, with claims 1, 16, 31, 41 being independent. Claims 1, 6, 16, 18, 19, 31, 36, 41, 43 have been amended. No claims have been cancelled or added. This Action is made FINAL.
Response to Arguments
Regarding the rejection of claims 1, 3, 4, 6, 19-21, 31, 33, 34, 36, applicant’s arguments have been considered, but are moot, because the new ground of rejection was caused by the amendment and does not rely on any reference applied in the aforementioned rejection for any teaching or matter specifically challenged in the argument.
Regarding the rejection of claims 16-18 and 41-43, applicant's arguments filed 7/30/2026 have been fully considered, but they are not persuasive.
On pages 19 and 20 of the arguments, the applicant argues that Deenoo does not teach “information associated with a conditional handover configuration for each conditional primary secondary cell change configuration of the plurality of conditional primary secondary cell change configurations, an indication of one or more conditional handover execution conditions and one or more primary secondary cell change execution conditions”, as recited in claim 16 and similarly recited in claim 41.
The reasons by the applicant for making this argument are stated on pg. 20 of the arguments.
Applicant argues that “The Office Action alleges that DEENOO discloses the subject matter of previously-presented claim 18. Office Action, p. 40. The cited section of DEENOO, at most, teaches that a WTRU may transmit an indication of CPAC execution in a failure message after a failed CHO. See DEENOO, T 157. However, DEENOO's teaching is a generic execution indication, but it does not disclose the per-configuration reporting information of the type now recited in claim 16”.
Examiner respectfully disagrees.
Previously, claim 18 required for the reference to teach a UE transmitting information associated with a conditional handover configuration with the plurality of conditional primary secondary cell change configurations or the plurality of conditional primary secondary cell addition configurations. Whereas, amended claim 16 now requires the reference to teach an information associated with a conditional handover configuration for each conditional primary secondary cell change configuration of the plurality of conditional primary secondary cell change configurations. This change caused a new ground of rejection to be made, and as such, the new rejection using Deenoo has been made below.
As indicated in the cited [0003], the WTRU receives a conditional reconfiguration associated with a primary secondary cell (PSCell) change, a PSCell addition, a secondary cell group (SCG) change, an SCG addition, etc., indicating information associated with a conditional handover configuration for each conditional primary secondary cell change configuration of a plurality of conditional primary secondary cell change configurations, namely those of the primary secondary cell (PSCell) change, PSCell addition, secondary cell group (SCG) change, SCG addition. These conditional reconfigurations are associated with a conditional handover, because, as indicated in the cited [0073], the conditional handover (CHO) is applicable to a conditional reconfiguration. An indication of the aforementioned information is transmitted by the WTRU, because, as indicated in the cited [0003], when the WTRU determines that the condition for application of the conditional reconfiguration is satisfied, it transmits a second message to the network entity, and when the WTRU determines that the application of the conditional reconfiguration has resulted in a failure, the WTRU transmits a third message to the network entity to indicate the failure.
Therefore, Deenoo teaches this limitation.
Claim Objections
Claim 41 is objected to for minor informalities and requires the following or other appropriate correction:
In claim 41, line 15, “for each conditional primary secondary cell change” should be amended, as follows: “for each conditional primary secondary cell change”, to correct an apparent typographical error.
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 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.
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 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 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 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 1, 3, 4, 6, 19-21, 31, 33, 34, 36 are rejected under 35 U.S.C. 103 as being unpatentable over Li, et al (US PG Publication 2025/0113267), hereafter Li, in view of Xu, et al (US PG Publication 2024/0214839), hereafter Xu.
Regarding claim 1, Li teaches

[0042] When the CHO to the primary cell and the CPAC to the secondary cell are configured at the same time, if the radio quality of any of the primary cell candidates meets the connection conditions, and if the connection conditions for any of the secondary cell candidates are met, the terminal device 141 connects to the primary cell candidate that meets the connection conditions, and to the secondary cell candidate that is associated with that primary cell and meets the connection conditions

If the connection to the other primary cell candidate is successful, there is no need to re-configure the secondary cell
(Based on the pre-configuration information received from the base station, the terminal device performs handover to any primary cell successfully, based on a condition associated with conditional handover being met, and subsequently performs a handover to other primary cell successfully, based on a condition associated with conditional handover being met));
initiate the selective secondary cell group activation or the subsequent conditional handover

If the connection to the other primary cell candidate is successful, there is no need to re-configure the secondary cell
