Claim Rejections - 35 USC § 103 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. In 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 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 1-5 and 11-15 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (2022/0225472), Kim hereinafter, in view of Laselva et al. (2024/0015605), Laselva hereinafter, in view of Kim et al. (2023/0328811), Kim811 hereinafter, further in view of Park et al. (2023/0087615), Park hereinafter. Re. claims 1 and 11, Kim teaches a wireless communication method (Fig. 28-30) for use in a second wireless network node (Fig. 29, CU-CP/New Base Station/Fig. 15), and a second wireless network node (Fig. 29, CU-CP/New Base Station/Fig. 15), comprising: at least one processor (Fig. 15, 1508), and a memory (Fig. 15, 1514), which is configured to store at least one program; wherein the at least one program, when executed by the at least one processor, enables the at least one processor (Fig.15, ¶0212-¶213) to: transmit, to a third wireless network node, a first indicator associated with buffering uplink (UL) data of a small data transmission (Fig. 28-30 & ¶0345 - Based on receiving the first F1 message, the new base station central unit control plane may send a retrieve UE context request message (first indicator) to an old base station central unit control plane where the retrieve UE context message (first indicator) may comprise assistance information of the SDT. Based on the retrieve UE context message, the old base station central unit control plane may determine to keep contexts of the wireless device. Fig. 28-30 & ¶0354 - Based on receiving the message, the new base station may send a retrieve UE context request message (first indicator) comprising assistance information of the SDT. Based on the retrieve UE context request message (first indicator), the old base station may determine to keep contexts of the wireless device (UE context of the wireless device) in the old base station), receive, from a first wireless network node, a radio resource control resume message of a wireless terminal (Fig. 28-30 & ¶0345 - Based on receiving the message, the new base station distributed unit may send a first F1 message to a new base station central unit control plane via the F1-C where the first F1 message may comprise at least one of: the RRC resume request message; the assistance parameters of the SDT; and/or the BSR), Yet, Kim does not expressly teach determine whether to transmit a second indicator to the third wireless network node based on a result of authenticating the wireless terminal based on the radio resource control resume message, However, in the analogous art, Laselva explicitly discloses determine whether to transmit a second indicator to the third wireless network node based on a result of authenticating the wireless terminal based on the radio resource control resume message (Fig. 14 & ¶0120 - Element e34 symbolizes an indication of subsequent SDT transmission, which may also include the second buffer status report, e.g. including an Inactive Radio network temporary identifier (I-RNTI) and/or a Cell Radio Network Temporary Identifier (C-RNTI). Element e35 symbolizes the control plane of the central unit 12-CU of the target node 12 determining a need to move the terminal device 16 to an RRC_CONNECTED mode, e.g. based on the second buffer status report, and triggering a forced UE context retrieval. Element e36 symbolizes an inactive UL data transfer message including the UL data and the first information I-1, the first information I-1 exemplarily this time indicating that a context relocation is required.

Element e38 symbolizes RETRIEVE UE CONTEXT RESPONSE message. Element e39 symbolizes an RRC Resume message,). PNG media_image2.png 670 818 media_image2.png Greyscale Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s invention of receiving/sending release message during small data transmission (SDT) in a wireless communication system to include Laselva’s invention of context relocation of a context of a terminal device in a 5G/NR (New Radio) wireless communication system, because it provides an efficient mechanism in performing small data transmission procedure during handover for machine-to-machine (M2M)-type communications in the a 5G/NR (New Radio) wireless communication system. (¶0002-¶0006, Laselva) Yet, Kim and Laselva do not expressly teach wherein the first indicator is configured per wireless terminal, per dedicated radio bearer, per protocol data unit session or per quality of service flow to control whether to buffer the UL data, However, in the analogous art, Kim811 explicitly discloses wherein the first indicator is configured per wireless terminal, per dedicated radio bearer, per protocol data unit session or per quality of service flow to control whether to buffer the UL data (Fig. 22 & ¶0309 - The retrieve UE context request message (i.e., first indicator) may comprise the UE identity and the MAC-I. Based on the retrieve UE context request message (i.e., first indicator), the old base station may be able to identify the contexts of the wireless device and verify the wireless device. Based on the identifying and the verifying, the old base station may send to a new base station a retrieve UE context response message comprising contexts of the UE (UE context (information)). The contexts may comprise requested PDU session list to be setup where each PDU session element of the request PDU session list comprises QoS flow identifiers (or DRB IDs) and QoS parameters per QoS flow (a DRB). Fig. 24 & ¶0329 - Based on the retrieve context request message (i.e., first indicator), the second base station may determine to keep anchor of the wireless device (to keep contexts of the wireless device (UE context)). Based on the determining, the second base station may send to the first base station a response message indicating the determining. The response message may comprise logical channel mapping information. The logical channel mapping information may comprise: QoS flow identifiers (or a DRB ID) of PDU sessions in the contexts; and logical channel identities (LCIDs) associated with the QoS flow identifiers. Based on the logical channel mapping information, the new base station may send a data forwarding request indicating QoS flow identifiers (or the DRB ID) of a logical channel of the first uplink data of the wireless device. Based on the data forwarding request, the anchor base station may send forwarding information for the first uplink data. The forwarding information may comprise the QoS flow identifiers (or the DRB ID) and a data forwarding address for the QoS flow identifiers (or the DRB ID)). Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s invention of receiving/sending release message during small data transmission (SDT) in a wireless communication system and Laselva’s invention of context relocation of a context of a terminal device in a 5G/NR (New Radio) wireless communication system to include Kim811’s invention of uplink data of Small Data Transmission (SDT) Procedure in a wireless communication system, because it provides an efficient mechanism in relocating a wireless device to a new base station due to varying RF condition with decreased signaling overheads along with no delays for transmission/reception of small data associated with the SDT procedure performed in the wireless communication system. (¶0314, Kim811) Yet, Kim, Laselva and Kim811 do not expressly teach wherein the second indicator is associated with transmitting the buffered UL data to a user plane function and wherein transmitting the second indicator comprises sending a BEARER CONTEXT MODIFICATION REQUEST message including the second indicator. However, in the analogous art, Park explicitly discloses wherein the second indicator is associated with transmitting the buffered UL data to a user plane function (Fig. 24 & ¶0262 - the CU-CP may send, to the CU-UP, a configuration message indicating a SDT procedure of the wireless device. The CU-UP may receive data (e.g., uplink data, downlink data, subsequent uplink data, subsequent downlink data, etc.) associated with the SDT procedure of the wireless device. Fig. 24 & ¶0272 - base station distributed unit may send, to the CU-CP, at least one of: the RRC request message and/or assistance information indicating whether the at least one subsequent data transmission is expected.

Based on the bearer identifier (e.g., and/or the logical channel identifier, the logical channel group identifier, the QoS flow identifier, the session identifier) of the assistance information, the CU-CP may resume/establish/setup the bearer for the wireless device (e.g., only the bearer among a plurality of suspended bearers of the wireless device; only the logical channel/the logical channel group/the QoS flow/the PDU session among a plurality of logical channels, logical channel groups, QoS flows, and/or PDU sessions of the wireless device). For resuming/establishing the bearer (e.g., the logical channel, the logical channel group, the QoS flow, the PDU session), the CU-CP may perform a UE context setup/modification procedure for the wireless device with the base station distributed unit and/or the CU-UP. For the UE context setup/modification procedure, the CU-CP may send, to the base station distributed unit and/or the CU-UP, a context setup/modification request message comprising the bearer identifier of the bearer (e.g., and/or the logical channel identifier, the logical channel group identifier, the QoS flow identifier, the session identifier)) and wherein transmitting the second indicator comprises sending a BEARER CONTEXT MODIFICATION REQUEST message including the second indicator (Fig. 24 & ¶0275 - the context setup/modification request message may comprise at least one of: a wireless device identifier (e.g., gNB-DU UE F1AP ID, gNB-CU UE F1AP ID, gNB-CU-CP UE F1AP ID, gNB-CU-UP UE F1AP ID, TMSI, S-TMSI, C-RNTI, PUR-RNTI, IMSI, etc.) of the wireless device. Fig. 24 & ¶0276 - the CU-CP may send, to the CU-UP and/or the base station distributed unit, a configuration message (e.g., the context setup/modification request message) indicating the SDT procedure of the wireless device. The configuration message may indicate that the context setup/modification request is for the SDT procedure of the wireless device. The sending by the CU-CP the configuration message by the CU-CP to the CU-UP may be based on the RRC request message. In an example, the CU-CP may receive, from the CU-UP and/or the base station distributed unit, a configuration response message (e.g., the acknowledge message) indicating configuration complete based on the configuration message. In an example, the configuration message may comprise at least one of: a bearer context setup request message, a bearer context modification request message, bearer context modification confirm message, and/or the like. ). PNG media_image3.png 495 676 media_image3.png Greyscale Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s invention of receiving/sending release message during small data transmission (SDT) in a wireless communication system and Laselva’s invention of context relocation of a context of a terminal device in a 5G/NR (New Radio) wireless communication system and Kim811’s invention of uplink data of Small Data Transmission (SDT) Procedure in a wireless communication system to include Park’s invention of completion indication of small data transmission (SDT) in a wireless communication system, because it provides an efficient mechanism in determining size of data (uplink/downlink) associated with the SDT procedure in the wireless communication system. (¶0264, Park) Re. Claims 2 and 12, Kim, Laselva, Kim811 and Park teach claims 1 and 11. Kim further teaches wherein the first indicator indicates whether to buffer the UL data (Fig. 28-30 & ¶0354 - Based on the retrieve UE context message (first indicator), the old base station central unit control plane may determine to keep contexts of the wireless device). Re. Claims 3 and 13, Kim, Laselva, Kim811 and Park teach claims 1 and 11. Yet, Kim does not expressly teach wherein determining whether to the second indicator to the third wireless network node based on the result of authenticating the wireless terminal based on the radio resource control resume message comprises: transmitting, to the third wireless network node, the second indicator when successfully authenticating the wireless terminal, or not transmitting, to the third wireless network node, the second indicator when unsuccessfully authenticating the wireless terminal. However, in the analogous art, Laselva explicitly discloses wherein determining whether to the second indicator to the third wireless network node based on the result of authenticating the wireless terminal based on the radio resource control resume message comprises: transmitting, to the third wireless network node, the second indicator when successfully authenticating the wireless terminal (Fig. 14 & ¶0120 - Element e34 symbolizes an indication of subsequent SDT transmission, which may also include the second buffer status report, e.g. including an Inactive Radio network temporary identifier (I-RNTI) and/or a Cell Radio Network Temporary Identifier (C-RNTI).

Based on the Xn DL message, the new base station may identify that the old base station determines to keep the contexts of the wireless device. Based on the identifying, the new base station may determine to continue small data transmission with the wireless device without the contexts of the wireless device. ….. Based on the uplink grant, the wireless device may send the 2nd uplink data to the new base station. The new base station may receive the 2nd uplink data from the wireless device. The old base station may send the 2nd uplink data to the core network entity (see UPF in Fig. 30, where, 2nd uplink data is received). Yet, Kim does not expressly teach wherein handling the buffered UL data based on the event associated with the second indicator from the second wireless network comprises: receiving, from the second wireless network node, the second indicator, and However, in the analogous art, Laselva explicitly discloses wherein handling the buffered UL data based on the event associated with the second indicator from the second wireless network comprises: receiving, from the second wireless network node, the second indicator (Fig. 14 & ¶0120 - Element e34 symbolizes an indication of subsequent SDT transmission, which may also include the second buffer status report, e.g. including an Inactive Radio network temporary identifier (I-RNTI) and/or a Cell Radio Network Temporary Identifier (C-RNTI). Element e35 symbolizes the control plane of the central unit 12-CU of the target node 12 determining a need to move the terminal device 16 to an RRC_CONNECTED mode, e.g. based on the second buffer status report, and triggering a forced UE context retrieval. Element e36 symbolizes an inactive UL data transfer message including the UL data and the first information I-1, the first information I-1 exemplarily this time indicating that a context relocation is required. Similar to element e10 of FIG. 13, … FIG. 14 symbolizes the control plane 14-CU-CP of the central unit of the anchor node 14 checking an authentication of the terminal device 16 and a transmission of the context of the terminal device 16 based on the received first information I-1 e36. Element e38 symbolizes RETRIEVE UE CONTEXT RESPONSE message. Element e39 symbolizes an RRC Resume message), Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filling date of the claimed invention to combine Kim’s invention of receiving/sending release message during small data transmission (SDT) in a wireless communication system and Kim811’s invention of uplink data of Small Data Transmission (SDT) Procedure in a wireless communication system to include Laselva’s invention of context relocation of a context of a terminal device in a 5G/NR (New Radio) wireless communication system, because it provides an efficient mechanism in performing small data transmission procedure during handover for machine-to-machine (M2M)-type communications in the a 5G/NR (New Radio) wireless communication system. (¶0002-¶0006, Laselva) Re. Claims 9 and 19, Kim, Kim811 and Park teach claims 6 and 16. Kim further discloses wherein the first wireless network node is a distributed unit of a base station, the second wireless network node is a control plane of a centralized unit of the base station and the third wireless network node is a user plane of the centralized unit of the base station. (See next) PNG media_image4.png 496 668 media_image4.png Greyscale Re. Claims 10 and 20, Kim, Kim811 and Park teach claims 6 and 16. Kim further discloses wherein the small data transmission is associated with a configured grant. (Fig. 28-30 & ¶0314 - An SDT procedure may comprise configured grant-based transmission of small data). Response to Arguments Applicant's arguments for §103 rejection filed on 07/06/2026 have been fully considered but they are not persuasive. Regarding remarks in page 11 for independent claims 1 and 11, applicant argues that Kim811 fails to teach, “wherein the first indicator is configured per wireless terminal, per dedicated radio bearer, per protocol data unit session or per quality of service flow to control whether to buffer the UL data”. Examiner respectfully disagrees with the applicant. For example, Kim811 discloses that the retrieve UE context request message (i.e., first indicator) may comprise the UE identity and the MAC-I. Based on the retrieve UE context request message (i.e., first indicator), the old base station may be able to identify the contexts of the wireless device and verify the wireless device. Based on the identifying and the verifying, the old base station may send to a new base station a retrieve UE context response message comprising contexts of the UE (UE context (information)). The contexts may comprise requested PDU session list to be setup where each PDU session element of the request PDU session list comprises QoS flow identifiers (or DRB IDs) and QoS parameters per QoS flow (a DRB). See ¶0309 along with Fig. 22. Kim811 further discloses that based on the retrieve context request message (i.e., first indicator), the second base station may determine to keep anchor of the wireless device (to keep contexts of the wireless device (UE context)). Based on the determining, the second base station may send to the first base station a response message indicating the determining. The response message may comprise logical channel mapping information. The logical channel mapping information may comprise: QoS flow identifiers (or a DRB ID) of PDU sessions in the contexts; and logical channel identities (LCIDs) associated with the QoS flow identifiers. Based on the logical channel mapping information, the new base station may send a data forwarding request indicating QoS flow identifiers (or the DRB ID) of a logical channel of the first uplink data of the wireless device. Based on the data forwarding request, the anchor base station may send forwarding information for the first uplink data. The forwarding information may comprise the QoS flow identifiers (or the DRB ID) and a data forwarding address for the QoS flow identifiers (or the DRB ID)). See ¶0329 along with Fig. 24, quite a contrast to applicant’s remarks at least at pages 8-10 as submitted on 07/06/2026. Regarding arguments in page 12 for motivation to combine Kim811’s reference with the references of Kim and Laselva: In response of applicant’s argument that Kim811’s reference would not be an obvious combination with the teachings of Kim and Laselva so as to suggest applicants' invention. The Examiner would like to point out the following statement as identified by court “It is not required that the prior art disclose or suggest the properties newly-discovered by an applicant in order for there to be a prima facie case of obviousness. See In re Dillon, 919 F.2d 688, 16 USPQ2d 1897, 1905 (Fed. Cir. 1990). Moreover, as long as some motivation or suggestion to combine the references is provided by the prior art taken as a whole, the law does not require that the references be combined for the reasons contemplated by the inventor. See In re Beattie, 974 F.2d 1309, 24 USPQ2d 1040 (Fed. Cir. 1992); In re Kronig, 539 F.2d 1300, 190 USPQ 425 (CCPA 1976) and In re Wilder, 429 F.2d 447, 166 USPQ 545 (CCPA 1970)”. In this case, the suggestion to combine the references, is enabled by Kim811 to provide an efficient mechanism in relocating a wireless device to a new base station due to varying RF condition with decreased signaling overheads along with no delays for transmission/reception of small data associated with the SDT procedure performed in the wireless communication system. (¶0314, Kim811) Regarding remarks in page 11 for independent claims 1 and 11, applicant argues that Kim or Laselva or Kim811 fails to teach, “wherein the second indicator is associated with transmitting the buffered UL data to a user plane function and wherein transmitting the second indicator comprises sending a BEARER CONTEXT MODIFICATION REQUEST message including the second indicator.”. Examiner agrees, however, in the analogous art, Park (2023/0087615[Wingdings font/0xF3] a new reference for the instant office action), discloses the limitation as mapped in §103 rejection. For these reasons, it is maintained that independent claims 1 and 11 are unpatentable over Kim, in view of Laselva, in view of Kim811 , further in view of Park. For similar reasons, it is maintained that independent claims 6 and 16 are unpatentable over Kim, in view of Kim811, further in view of Park. As all other dependent claims depend either directly or indirectly from the independent claims 1, 6, 11 and 16, similar rationale also applies to all respective dependent claims. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
