§103 §DOUBLEPATENT
DETAILED ACTION The following is a second non-final office action in response to applicant’s filing of Notice of Appeal filed on 07/23/2026 along with a Pre-Appeal Brief Conference Request filed on 07/23/2026, and also for the response of the office action mailed on 05/28/2026. Independent claims 1, 13 and 18 are amended. Claims 2, 11-12, 14 and 19 are cancelled. A new set of claims 21-25 were added on 02/04/2026. Therefore, claims 1, 3-10, 13, 15-18 and 20-25 are pending and addressed below. Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.

However, in the analogous art, R2-1802149-CATT explicitly discloses wherein activation/deactivation states of the first data behavior, the second data behavior, and the third data behavior are same or different; (See Option 1: unified duplication activation/deactivation MAC CEs in MCG and SCG along with Fig. 4 & Option 2: separate duplication activation/deactivation MAC CEs in MCG and SCG along with Fig. 6 as shown below) PNG media_image3.png 202 628 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 Baek’s invention of a method and apparatus for controlling packet duplication transmission in a wireless communication system to include R2-1802149-CATT’s invention of packet duplication activation/deactivation via MAC-CE (medium access control-control element ) in a wireless communication system, because it provides an efficient mechanism for a user equipment (UE), when the UE is connected to both MCG (Master Cell group) and SCG (Secondary cell group) of a plurality of network nodes, UE maintains two separate duplication activation/deactivation MAC CEs from MCG and SCG with each MAC-CE bitmap indicating duplicate DRBs (Data Radio bearer) in the corresponding network node of the plurality of network nodes operating in the wireless communication system. (§2-§3, R2-1802149-CATT) Yet, Baek and R2-1802149-CATT do not expressly teach the processor is configured to indicate, through the MAC entity, a state of duplication data between the first PDCP entity corresponding to the DRB and each of the plurality of RLC entities to a higher layer. However, in the analogous art, Xu explicitly discloses the processor (Fig. 8, 800) is configured to indicate, through the MAC entity, a state of duplication data between the first PDCP entity corresponding to the DRB and each of the plurality of RLC entities to a higher layer (Fig. 1-4 & ¶0004 - bearer mapping (see, also ¶0188-¶0189/¶0228-¶0232) method and a device thereof, a base station and a terminal are provided in the present disclosure, so as to solve how to unify the mapping relationship between the bitmap of the MAC CE of the duplication activation/deactivation at the network side and that at the terminal side. Fig. 1-4 & ¶0009 - a terminal to sort the bearer IDs according to a preset sorting rule, to obtain a bearer ID sequence, and indicating a mapping relationship between each of the bearer IDs (see, also ¶0188-¶0189) in the bearer ID sequence and the bitmap in the MAC CE. Fig. 1-4 & ¶0134 - Step 101: indicating, in an implicit or explicit manner, a mapping relationship between a bearer ID (see, also ¶0188-¶0189/¶0228-¶0232) and a bitmap in a media access control layer control element (MAC CE), where the MAC CE is a control element for a duplication activation indication or deactivation indication, and the bearer ID is an ID of a bearer configured with a duplication function. Fig. 1-4 & ¶0135 - MAC layer controls, in the form of MAC CE, the activation or deactivation of the duplication function of the bearer data packet. Specifically, the MAC layer carries, in the MAC CE, a bitmap indicating whether the bearer is activated or deactivated. The bits in the bitmap are in a one-to-one correspondence to the bearers configured with the duplication function. The UE side can determine, according to the “0” or “1” bit in the bitmap carried by the network side MAC CE, whether the corresponding duplication data packet of the bearer at the corresponding position need to be activated or deactivated, and inform the high layer of the result. The Packet Data Convergence Protocol (PDCP) layer may determine, based on the activated or deactivated state, the use and status of the corresponding radio link control RLC entity and the logical channel. Fig. 1-4 & ¶0184 - in the process of establishing a bearer at a high layer, a new IE plaintext is added to indicate the index position of the bearer.

PNG media_image2.png 481 1007 media_image2.png Greyscale Yet, Baek does not expressly teach activation/deactivation states of the first data behavior, the second data behavior, and the third data behavior are same or different; However, in the analogous art, R2-1802149-CATT explicitly discloses activation/deactivation states of the first data behavior, the second data behavior, and the third data behavior are same or different; (See Option 1: unified duplication activation/deactivation MAC CEs in MCG and SCG along with Fig. 4 & Option 2: separate duplication activation/deactivation MAC CEs in MCG and SCG along with Fig. 6 as shown next) PNG media_image3.png 202 628 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 Baek’s invention of a method and apparatus for controlling packet duplication transmission in a wireless communication system to include R2-1802149-CATT’s invention of packet duplication activation/deactivation via MAC-CE (medium access control-control element ) in a wireless communication system, because it provides an efficient mechanism for a user equipment (UE), when the UE is connected to both MCG (Master Cell group) and SCG (Secondary cell group) of a plurality of network nodes, UE maintains two separate duplication activation/deactivation MAC CEs from MCG and SCG with each MAC-CE bitmap indicating duplicate DRBs (Data Radio bearer) in the corresponding network node of the plurality of network nodes operating in the wireless communication system. (§2-§3, R2-1802149-CATT) Re. Claim 17, Baek and R2-1802149-CATT teach claim 13. Baek also teaches wherein the processor is further configured to: receive capability information of the terminal device reported by the terminal device, wherein the capability information comprises whether the first PDCP entity corresponding to the DRB supports a behavior of transmitting data with at least three RLC entities. (Fig. 11 & ¶0131: ¶0134 - UE may inform a base station of whether the UE supports a packet duplication transmission function. At this time, the UE may include information about whether a packet duplication transmission function is supported in a UE capability message 1k-10. Also, the UE capability message 1k-10 may include at least one piece of information related to packet duplication transmission of the UE. The information may be as follows. a maximum number of RLC entities capable of performing packet duplication in a single radio bearer. .. a maximum number of RLC entities capable of being set in a single radio bearer. …. whether packet duplication transmission using three RLC entities or more is supportable). PNG media_image4.png 170 305 media_image4.png Greyscale Re. Claim 24, Baek and R2-1802149-CATT teach claim 13. Yet, Baek does not expressly teach wherein the transceiver is specifically configured to: send a first type of MAC CE or a second type of MAC CE to the terminal device, wherein the first type of MAC CE is used for indicating a data behavior between an RLC entity and the first PDCP entity corresponding to a first DRB, and the second type of MAC CE is used for indicating a data behavior between an RLC entity and the first PDCP entity corresponding to a second DRB, wherein the first DRB and the second DRB are different. However, in the analogous art, R2-1802149-CATT explicitly discloses wherein the transceiver is specifically configured to: send a first type of MAC CE or a second type of MAC CE to the terminal device, wherein the first type of MAC CE is used for indicating a data behavior between an RLC entity and the first PDCP entity corresponding to a first DRB, and the second type of MAC CE is used for indicating a data behavior between an RLC entity and the first PDCP entity corresponding to a second DRB, wherein the first DRB and the second DRB are different. (Option 2 <See Fig.6 as reproduced next>: separate duplication activation/deactivation MAC CEs in MCG and SCG. In option 2, gNB and UE construct/interpret the duplication activation/deactivation MAC CE according to the duplicate DRBs within the link between the gNB and UE. UE maintains two duplication activation/deactivation MAC CEs (different bitmaps) from different NW nodes. Note Option 2 also respects the agreement that “mapping between DRB and the MAC bitmap is based on order of DRB ID(s) of the duplicate configured DRB(s)”, with the addition that it is restricted to the DRB ID(s) of the duplicate configured DRB(s) in each CG. In option 2, UE should maintain two duplication activation/deactivation MAC CEs and identify the MAC CE format based on the NW node transmitting the MAC CE. Since there are two separate MAC entities in the DC case and UE should maintain the two MAC entities simultaneously, PNG media_image5.png 330 520 media_image5.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 Baek’s invention of a method and apparatus for controlling packet duplication transmission in a wireless communication system to include R2-1802149-CATT’s invention of packet duplication activation/deactivation via MAC-CE (medium access control-control element ) in a wireless communication system, because it provides an efficient mechanism for a user equipment (UE), when the UE is connected to both MCG (Master Cell group) and SCG (Secondary cell group) of a plurality of network nodes, UE maintains two separate duplication activation/deactivation MAC CEs from MCG and SCG with each MAC-CE bitmap indicating duplicate DRBs (Data Radio bearer) in the corresponding network node of the plurality of network nodes operating in the wireless communication system. (§2-§3, R2-1802149-CATT) Re. Claim 25, Baek and R2-1802149-CATT teach claim 13. Yet, Baek does not expressly teach wherein the first type of MAC CE and the second type of MAC CE are different. However, in the analogous art, R2-1802149-CATT explicitly discloses wherein the first type of MAC CE and the second type of MAC CE are different.

(§2-§3, R2-1802149-CATT) Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Baek, in view of R2-1802149-CATT, further in view of R2-1706716- Huawei. Re. Claim 15, Baek and R2-1802149-CATT claim 13. Yet, Baek and R2-1802149-CATT do not expressly teach send a Radio Resource Control (RRC) signaling to the terminal device, wherein the RRC signaling comprises information for indicating an initial state of duplication data of the first PDCP entity corresponding to the DRB. However, in the analogous art, R2-1706716- Huawei explicitly discloses send a Radio Resource Control (RRC) signaling to the terminal device, wherein the RRC signaling comprises information for indicating an initial state of duplication data of the first PDCP entity corresponding to the DRB. ((§2.4 - Solution 1: The initial state (activated or deactivated) is configurable by RRC signalling. In case duplication is not active, the two legs are decoupled from the associated carriers. And it is UE implementation to choose one of the legs for data transmission. For this solution, when configuring the duplication per DRB or SRB, the gNB can add an indication (e.g. a packet duplication flag) to the RRC signalling to inform the UE whether the state of UL duplication is active. If the initial state of packet duplication is not active, the two legs should be decoupled from the associated carriers. And one of the two legs should be used for data transmission by UE implementation.). 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 Baek’s invention of a method and apparatus for controlling packet duplication transmission in a wireless communication system and R2-1802149-CATT’s invention of packet duplication activation/deactivation via MAC-CE (medium access control-control element ) in a wireless communication system to include R2-1706716- Huawei’s invention of Configuration and control of packet duplication in a wireless communication system, because it enables a Radio Access Network (RAN) in making selection for an efficient and effective solution for initial state of duplication in both DC (Dual Connectivity) and CA (Carrier Aggregation) operations, in turns, improves reliability for radio bearer which requires packet duplication for operating in the wireless communication system. (§2.4, R2-1706716- Huawei) Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over Baek, in view of R2-1802149-CATT, further in view of Sun. Re. Claim 16, Baek and R2-1802149-CATT teach claim 13. Yet, Baek, R2-1802149-CATT and Xu do not expressly teach end second indication information to the terminal device, wherein the second indication information is used for indicating whether the MAC CE is an MAC CE comprising the first indication information, wherein the transceiver is specifically configured to: send a reserved index in a Logical Channel Identifier (LCID) of a DownLink Shared Channel (DL-SCH) to the terminal device, wherein the reserved index is used for indicating whether the MAC CE is the MAC CE comprising the first indication information.. However, in the analogous art, Sun explicitly discloses end second indication information to the terminal device, wherein the second indication information is used for indicating whether the MAC CE is an MAC CE comprising the first indication information, wherein the transceiver is specifically configured to: send a reserved index in a Logical Channel Identifier (LCID) of a DownLink Shared Channel (DL-SCH) to the terminal device, wherein the reserved index is used for indicating whether the MAC CE is the MAC CE comprising the first indication information.. ( PNG media_image7.png 176 373 media_image7.png Greyscale PNG media_image6.png 446 509 media_image6.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 Baek’s invention of a method and apparatus for controlling packet duplication transmission in a wireless communication system and R2-1802149-CATT’s invention of packet duplication activation/deactivation via MAC-CE (medium access control-control element ) in a wireless communication system to include Sun’s invention of Media Access Control (MAC) Protocol Data Unit (PDU) transmission method and a MAC PDU transmission apparatus in a wireless communication system, because it provides an efficient mechanism for identifying an expanded MAC CE (medium access control-control element ) type in a MAC PDU for a transmitting/receiving device operating in the wireless communication system. (¶0002-¶0006, Sun) Response to Arguments Applicant’s arguments filed on 07/23/2026 with respect to independent claims 1, 13 and 18 have been considered but they are not persuasive. Also, based on an updated search following the office action sent on 08/06/2026, a plurality of newly found NPL documents, such as, 3GPP TSG-RAN WG2 #99; R2-1707921; Source: CATT; Title: Duplication Activation/Deactivation MAC CE; Berlin, Germany, 21 - 25 Aug 2017 & 3GPP TSG-RAN WG2#101; R2-1802149; Source: CATT; Title: Duplication activation/deactivation MAC CE; Athens, Greece, 26thFebruary-2ndMarch 2018, triggered a new search following the discovering of a plurality of relevant prior arts (See PTO-892), which are very closed to inventive concepts as claimed in independent claims 1, 13 and 18, and subsequent dependent claims as claimed by the applicant, hence, a second non final office action is being sent out. Regarding arguments in pages 1-2 as submitted on 07/23/2026 for double patenting issues, applicant’s assertion that the amended claim set is patentably distinct from the claims of U.S. Patent No. US 11,991,556 B2, that is, the present application does not constitute double patenting with No. US 11,991,556 B2. Examiner respectfully disagrees with the applicant. Please see the updated double patenting rejection. Applicant is requested to submit a terminal disclaimer (TD) to overcome the nonstatutory double patenting rejection. A rejection based on a nonstatutory type of double patenting can be avoided by filing a terminal disclaimer in the application or proceeding in which the rejection is made. In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Knohl, 386 F.2d 476, 155 USPQ 586 (CCPA 1967); and In re Griswold, 365 F.2d 834, 150 USPQ 804 (CCPA 1966). The use of a terminal disclaimer in overcoming a nonstatutory double patenting rejection is in the public interest because it encourages the disclosure of additional developments, the earlier filing of applications, and the earlier expiration of patents whereby the inventions covered become freely available to the public. In re Jentoft, 392 F.2d 633, 157 USPQ 363 (CCPA 1968); In re Eckel, 393 F.2d 848, 157 USPQ 415 (CCPA 1968); In re Braithwaite, 379 F.2d 594, 154 USPQ 29 (CCPA 1967). See MPEP §804.02. None of the earlier prior arts are used in the instant office action, hence, moot. For reasons as explained supra, it is maintained that independent claims 1 and 18, are rejected under 35 U.S.C. 103 as being unpatentable over Baek et al. (2021/0297899 [Wingdings font/0xF3] new reference), in view of R2-1802149-CATT ([Wingdings font/0xF3] new reference), further in view of Xu et al. (2020/0367091 [Wingdings font/0xF3] new reference), For similar reason, it is maintained that independent claim 13, is rejected under 35 U.S.C. 103 as being unpatentable over Baek et al. (2021/0297899 [Wingdings font/0xF3] new reference), in view of R2-1802149-CATT ([Wingdings font/0xF3] new reference). As all other dependent claims depend either directly or indirectly from the independent claims 1, 13 and 18, similar rationale also applies to all respective dependent claims. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. 3GPP TSG-RAN WG2 #99; R2-1707921; Source: CATT; Title: Duplication Activation/Deactivation MAC CE; Berlin, Germany, 21 - 25 Aug 2017.
