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.
Claims 2 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over Wu et al. US 20260032777 A1 (Domestic Priority July 12, 2022) in view of Fujishiro et al. US 20230262423 A1 (Domestic Priority October 22, 2020).
Wu discloses all the claim limitations as set forth above but fails to explicitly disclose: Regarding claim 2 (Currently Amended), the method according to claim 1, wherein the receiving the inactive multicast broadcast service according to the first inactive multicast broadcast service configuration corresponding to the first cell where the terminal resides comprises at least one of: receiving the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration corresponding to the first cell; or stopping using a second inactive multicast broadcast service configuration corresponding to a second cell where the terminal has resided.
However Fujishiro from a similar field of endeavor discloses: the method according to claim 1, wherein the receiving the inactive multicast broadcast service according to the first inactive multicast broadcast service configuration corresponding to the first cell where the terminal (see, UE is in the RRC connected state in a cell of the gNB where the gNB transmits an RRC Reconfiguration message including the first MBS configuration and the second MBS configuration to the UE, sections 0131-0132 Fujishiro) resides comprises at least one of: receiving the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration corresponding to the first cell (see, first MBS configuration may include an identifier indicating that the configuration may be used in the RRC idle state or the RRC inactive state, section 0134 Fujishiro); or stopping using a second inactive multicast broadcast service configuration corresponding to a second cell where the terminal has resided (see, second MBS configuration may include an identifier indicating that this is a reception configuration for the RRC idle state or the RRC inactive state, or may include an identifier indicating that the configuration is not to be used in the RRC connected state, section 0135 Fujishiro).
In view of the above, it would have been obvious before the effective filling date of the claim invention to a person having ordinary skill in the art of which the claimed invention pertains to modify the method of Wu with the MBS configurations as taught by Fujishiro. The motivation would have been to improve a mobile communication system providing a multicast and broadcast service.
Wu discloses all the claim limitations as set forth above but fails to explicitly disclose: Regarding claim 5 (Original), the method according to claim 2, wherein the receiving the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration comprises: determining whether the second inactive multicast broadcast service configuration corresponding to the second cell where the terminal has resided is the same as the first inactive multicast broadcast service configuration; and receiving, in response to the second inactive multicast broadcast service configuration being different from the first inactive multicast broadcast service configuration, the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration.
However Fujishiro from a similar field of endeavor discloses: the method according to claim 2, wherein the receiving the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration comprises: determining whether the second inactive multicast broadcast service configuration corresponding to the second cell where the terminal has resided is the same as the first inactive multicast broadcast service configuration (see, the validity period of the MBS configuration may be different for each MBS session, section 0115 Fujishiro); and receiving, in response to the second inactive multicast broadcast service configuration being different from the first inactive multicast broadcast service configuration (see, the validity period of the MBS configuration may common (only one) for all of the MBS sessions, 0115 Fujishiro), the inactive multicast broadcast service by using the first inactive multicast broadcast service configuration (see, the first MBS configuration may include an identifier indicating that the configuration may be used in the RRC idle state or the RRC inactive state, section 0134 Fujishiro).

In view of the above, it would have been obvious before the effective filling date of the claim invention to a person having ordinary skill in the art of which the claimed invention pertains to modify the combination of Wu and Fujishiro with the MBS sessions as taught by Hong. The motivation would have been to improve processing multicast and broadcast services (MBS) data.
The combination of Wu and Fujishiro discloses all the claim limitations as set forth above but fails to explicitly disclose: Regarding claim 8 (Currently Amended), the method according to claim 2, wherein the first inactive multicast broadcast service configuration comprises a multicast broadcast service configuration specific to a bandwidth part (BWP) corresponding to the first cell.

In view of the above, it would have been obvious before the effective filling date of the claim invention to a person having ordinary skill in the art of which the claimed invention pertains to modify the combination of Wu and Fujishiro with the MBS sessions as taught by Hong. The motivation would have been to improve processing multicast and broadcast services (MBS) data.
