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. 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) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived 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 6, 9, 13, 19, 22, and 26, are rejected under 35 U.S.C. 103 unpatentable over TEYEB et al. (WO 2022/024092) in view of HONG et al. (US 2019/0268799). Regarding claim 6, TEYEB discloses the method of claim 1, but does not explicitly disclose wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises data radio bearer (DRB) ID information, wherein the DRB ID information is ID information of a DRB having to-be-transmitted data in the SCG and is indicated by a bitmap, wherein the bitmap comprises any one of the following: wherein the RLC bearer only comprises a split bearer of which a primary path is in the SCG in case that the RLC bearer is a split bearer. However, HONG discloses wherein in case that the target information comprises the target RRC signaling [see ¶ 356; configure/update RRC connection, for example, to configure/modify/release a radio bearer], the target RRC signaling comprises data radio bearer (DRB) ID information [see ¶ 358; radio bearer configuration information may include data radio bearer (DRB) configuration information (e.g. drb-ToAddModList)], wherein the DRB ID information is ID information of a DRB having to-be-transmitted data in the SCG and is indicated by a bitmap [see ¶ 359; SRB configuration information (e.g. srb-ToAddMod) and the DRB configuration information (e.g. drb-ToAddMod) may include PDCP configuration information], wherein the bitmap comprises any one of the following: wherein the RLC bearer only comprises a split bearer of which a primary path is in the SCG in case that the RLC bearer is a split bearer [see ¶ 359; SCG split bearer, or the like has caused more radio bearer types to be defined than the LTE, resulting in radio bearer reconfiguration procedure]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention was made to provide “wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises data radio bearer (DRB) ID information, wherein the DRB ID information is ID information of a DRB having to-be-transmitted data in the SCG and is indicated by a bitmap, wherein the bitmap comprises any one of the following: wherein the RLC bearer only comprises a split bearer of which a primary path is in the SCG in case that the RLC bearer is a split bearer” as taught by HONG in the system of TEYEB, so that it would enabling a user equipment to perform the duplicate transmission of data through one radio bearer [see HONG; ¶ 8]. Regarding claim 9, TEYEB discloses the method of claim 1, but does not explicitly disclose wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises logical channel group ID (LCG ID) information, wherein the LCG ID information is ID information of a LCG having to-be-transmitted data in the SCG, and is indicated by a bitmap or by an LCG ID list. However, HONG discloses wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises logical channel group ID (LCG ID) information [¶ 179; duplicate transmission bearer may have a cell identifier or a cell identifier list for each logical channel\], wherein the LCG ID information is ID information of a LCG having to-be-transmitted data in the SCG, and is indicated by a bitmap or by an LCG ID list [¶ 182; the logical channel group list may be included in cell/cell group configuration information in sequence or as a bitmap]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention was made to provide “wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises logical channel group ID (LCG ID) information, wherein the LCG ID information is ID information of a LCG having to-be-transmitted data in the SCG, and is indicated by a bitmap or by an LCG ID list” as taught by HONG in the system of TEYEB, so that it would enabling a user equipment to perform the duplicate transmission of data through one radio bearer [see HONG; ¶ 8]. Regarding claim 13, TEYEB discloses the method of claim 12. TEYEB further discloses further comprising: performing, based on the target information, one or more of the following: reconfiguring the target bearer for the MCG and/or the SCG [see ¶ 135; SCG configuration and start operating according to the SCG configuration that is resumed (e.g. resumption of SCG bearers)]; activating the SCG [see ¶ 135; activating the PSCell and at least starting to monitor PDCCH of one of the cells of the SCG, which triggered by network signaling]. TEYEB does not explicitly disclose wherein the target bearer is used for transmitting data corresponding to the buffer data status information of the SCG. However, HONG wherein the target bearer is used for transmitting data corresponding to the buffer data status information of the SCG [¶¶ 161-162, 306; wherein the target bearer is used for transmitting data corresponding to the buffer data status information of the SCG]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention was made to provide “wherein the target bearer is used for transmitting data corresponding to the buffer data status information of the SCG” as taught by HONG in the system of TEYEB, so that it would enabling a user equipment to perform the duplicate transmission of data through one radio bearer [see HONG; ¶ 8]. Regarding claims 19 and 22, the claims recite the terminal of claim 14 to perform the method recited as in claims 6 and 9 respectively; therefore, claims 19 and 22 rejected along the same rationale that rejected in claims 6 and 9 respectively. Regarding claim 26, the claim recites the network device of claim 25 to perform the method recited as in claim 13; therefore, claim 26 rejected along the same rationale that rejected in claim 13. Claims 7-8, 11, 20-21, and 24, are rejected under 35 U.S.C. 103 unpatentable over TEYEB et al. (WO 2022/024092) in view of HAN et al. (CN 111182584). Regarding claim 7, TEYEB discloses the method of claim 1, but does not explicitly disclose wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises data radio bearer (DRB) ID, wherein the DRB ID is an ID of a DRB having to-be-transmitted data in the SCG, and is any one of the following: a DRB ID of a radio link control (RLC) bearer in an SCG; a DRB ID of an RLC bearer in an SCG, wherein the RLC bearer does not belong to a split bearer; or a DRB ID of an RLC bearer in an SCG, wherein the RLC bearer only comprises a split bearer of which a primary path is in the SCG in case that the RLC bearer is a split bearer. However, HAN discloses wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises data radio bearer (DRB) ID [page 10 line 44; wherein the first data radio bearer can be SCG data radio bearer or data radio bearer], wherein the DRB ID is an ID of a DRB having to-be-transmitted data in the SCG, and is any one of the following: a DRB ID of a radio link control (RLC) bearer in an SCG; a DRB ID of an RLC bearer in an SCG [page 11 lines 9-13; SCG first uplink buffer data quantity of the data radio bearer to inform the network device of the bearer identifier corresponding to first data radio bearer uplink buffer, also see page 8 lines 38-40]. Therefore, it would have been obvious to one having ordinary skill in the art before the effective filling date of the claimed invention was made to provide “wherein in case that the target information comprises the target RRC signaling, the target RRC signaling comprises data radio bearer (DRB) ID, wherein the DRB ID is an ID of a DRB having to-be-transmitted data in the SCG, and is any one of the following: a DRB ID of a radio link control (RLC) bearer in an SCG; a DRB ID of an RLC bearer in an SCG, wherein the RLC bearer does not belong to a split bearer; or a DRB ID of an RLC bearer in an SCG, wherein the RLC bearer only comprises a split bearer of which a primary path is in the SCG in case that the RLC bearer is a split bearer” as taught by HAN in the system of TEYEB, so that it would activate the SCG under the condition of receiving the SCG request sent by the user equipment, can ensure the user equipment transmits uplink data through the SCG. [see HAN; page 7 lines 36-38].
