Office Action

§103 §DP
Detailed Action The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . The Office Action is in response to claims filed on 10/14/25 where claims 1-20 are pending and ready for examination. The information disclosure statement (IDS) submitted on 3/26/2024 and 1/23/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,996,993 Although the claims at issue are not identical, they are not patentably distinct from each other because the claims from the Instant Application No. 18419691 are a broadened version of the claims from U.S. Patent No. 11,996,993. Therefore it would have been obvious to one of ordinary skill in the art to apply the teachings from the claims and/or limitations from U.S. Patent No. 11,996,993 to solve and/or contemplate the problems and/or features from the Instant Application No. 18419691. More importantly, the Examiner had conducted a side by side analysis of the claims and/or limitations between the Instant Application No. 18419691 and U.S. Patent No. 11,996,993. An example is illustrated below: Instant Application No. 18419691 U.S. Patent No. 11,996,993 1. A method implemented by a gateway management device and comprising: receiving, from a steering function (SF) device, a service request comprising service information of a terminal device that is to perform access to an uplink network; and determining, based on the service information, a first user plane (UP) device and a first sliced network, wherein the first sliced network is between the first UP device and the SF device and is for transmitting a data packet of the terminal device. PNG media_image1.png 262 340 media_image1.png Greyscale PNG media_image2.png 49 335 media_image2.png Greyscale As detailed above the Examiner conducted a side by side analysis of the all claims. 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. Claims 1, 5-9, and 13-15 are rejected under 35 USC 103 as being unpatentable over ETSI, “MEC in 5G Networks”, June 2018 in view of Feder (US 11,310,731) Regarding claim 1, ETSI discloses a method implemented by a gateway management device and comprising: receiving, from a steering function (SF) device, a service request comprising service information of a terminal device that is to perform access (ETSI; See e.g. Page 10 PNG media_image3.png 413 1263 media_image3.png Greyscale See e.g. Page 11 PNG media_image4.png 297 1238 media_image4.png Greyscale The “Application Function (AF)” is a network function that initiates traffic steering, which is functionally equivalent to the claimed “steering function (SF)” because both initiate control of routing of UE traffic. The phrase “request services to configure the rules” explicitly discloses a service request sent from the AF to the core network. The phrase “traffic steering request may contain ... information about target UE(s)” explicitly disclose that the service request comprises service information of a terminal device. The UE is the terminal device , and the request is made for routing/access of the UE’s traffic, which corresponds to the terminal device “that is to perform access” ); and determining, based on the service information, a first user plane (UP) device and a first sliced network (ETSI; see e.g. Page 9 PNG media_image5.png 287 1230 media_image5.png Greyscale See e.g. Page 7 PNG media_image6.png 221 1227 media_image6.png Greyscale See e.g. Page 10 PNG media_image7.png 416 1271 media_image7.png Greyscale The phrase “selection/re-selection and control of the UPF” and “selecting and controlling the UPF” explicitly discloses determining a UPF. The phrase “traffic steering requests may contain ... information about target UE(s)” discloses that the determination is made based on service information of the UE. Therefore the reference explicitly discloses determining based on service information, a first user plane (UPF device) PNG media_image8.png 225 1264 media_image8.png Greyscale This determination is based on user/service information, because the slice is selected “for users” Therefore the reference discloses determining a first network slice) Although ETSI discloses that a steering function can transmit user data, and not merely control plane signaling, ETSI does not expressly disclose: wherein the first sliced network is between the first UP device and the SF device and is for transmitting a data packet of the terminal device. However in analogous art Feder discloses: wherein the first sliced network is between the first UP device and the SF device and is for transmitting a data packet of the terminal device (Feder; The Examiner notes that the limitation is equivalent to the problem of enforcing steering decisions on slice-based UPF selection and user plane path changes Feder teaches that steering decisions are not abstract control decisions, but are enforced by changing which UPF is selected and by changing which UPF is selected an by changing the user-plane path during an active PDU session. A person of ordinary skill in the art would therefore understand that, to apply steering based on slice selection, the steering function must operate at the interface between control plane decisions (SMF) and user plane enforcement (UPF), because PF reallocation and path changes are the concrete mechanism by which steering is realized. Thus Feder provides a predictable way to place the steering function between the control plane and the user plane in order to solve the problem of enforcing slice based steering on user traffic. See e.g. Column 9, Lines 34 – 39 “... AMF can report UE presence in an Area of Interest, reporting usage via “UE mobility event notification” service, as described in ETSI TS 123 501 clause 5.3.4.4. Upon reception of a notification from AMF, the SMF determines how to deal with the PDU Session, e.g. reallocate UPF. When a PDU Session is established or modified, or when the user plane path has been changed, such as UPF re-allocation/addition/removal ...”) Therefore it would have been prima facie to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Feder’s scheme. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of providing data to UEs. Regarding claim 5, ETSI in view of Feder disclose the method of claim 1, wherein the service information comprises 5. a user identifier of the terminal device (ETSI teaches service information is mapped to target UES which requires a generic identifier to be necessarily present (e.g. associated with a data structure) such that the mapping may be executed; See e.g. Page 11 PNG media_image4.png 297 1238 media_image4.png Greyscale ). Regarding claim 6, ETSI in view of Feder disclose the method of claim 1, further comprising sending a configuration 6. instruction to the SF device for instructing the SF device to configure an interface corresponding to the first sliced network on the SF device (ETSTI in view of Feder teaches a steering function device that is connected to the user plane via a slice network, as required by claim 1, As a matter of necessary operation, the presence of a slice network between the steering function device and the user plane device requires an interface on the steering function device corresponding to that slice network. ETSI further teaches sending configuration instructions to network functions in order to establish and configure communication interfaces for traffic steering and forwarding. A person of ordinary skill in the art would recognize that, in order to enable the slice between the steering function device and the user plane device, a configuration instruction must be sent to the steering function device to configure the corresponding interface). Regarding claim 7, ETSI in view of Feder disclose the method of claim 1, further comprising sending a configuration instruction to the SF device for instructing the SF device to transmit packets of the terminal device to the first sliced network (The combined solution per Independent claim 1 provide for a sliced network positioned between the steering function device and the user plane device. As a matter of necessary operation, once a terminal device is mapped to the first slice network, the steering function must transmit packets of the terminal device to that slice network. A person of ordinary skill in the art would therefore recognize that a configuration instruction must be sent to the steering function device to instruct it to transmit packets to the first slice network) Regarding claim 8, ETSI in view of Feder disclose the method of claim 7, wherein the configuration instruction 8. comprises a network identifier of the first sliced network (Per Independent claim 1 a NSSAI is readily available to facilitate sliced network identification). Regarding claim 9, claim 9 comprises the same and/or similar subject matter as claim 1 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 13, claim 13 comprises the same and/or similar subject matter as claim 5 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 14, claim 14 comprises the same and/or similar subject matter as claim 6 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 15, claim 154 comprises the same and/or similar subject matter as claim 7 and is considered an obvious variation; therefore it is rejected under the same rationale. Claims 2 , 10, 17-18 and 20 are rejected under 35 USC 103 as being unpatentable over ETSI, in view of Feder (US 11,310,731) and in further view of Ghadge (US 20200145278) Regarding claim 2, ETSI in view of Feder and disclose the method of claim 1, ETSI does not disclose further comprising managing multiple user plane (UP) devices of a broadband network gateway (BNG) system, wherein the multiple UP devices comprise the first UP device. Ghadge discloses: managing multiple user plane (UP) devices of a broadband network gateway (BNG) system, wherein the multiple UP devices comprise the first UP device (Ghadge; see e.g. [0037] In some embodiments, when a user plane entity becomes active, the user plane entity may use a border gateway protocol (BGP) to advertise one or more routes to neighboring routers with lower cost. Accordingly, the active user plane entity may (e.g., always) receive new data that is routed to the user plane entity) Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate Ghadge’s scheme. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of managing ad delivering network traffic. Regarding claim 10, claim 10 comprises the same and/or similar subject matter as claim 2 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 17, claim 17 comprises the same and/or similar subject matter as claim 2 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 18, ETSI in view of Feder and in further view of Ghadge disclose the BNG system of claim 17, wherein the gateway management device is configured to manage the multiple UP devices of the BNG system, and wherein the multiple UP devices comprise the first UP device (Per independent claim 17, once the gateway management device is configured to select and control a first UP device among multiple UP devices, it necessarily manages the multiple UP devices of the BNG system, and the first UP device is one of those multiple UP devices). Regarding claim 20, ETSI in view of Feder and in further view of Ghadge disclose The BNG system of claim 17, wherein the gateway management 20. device is further configured to send a configuration instruction to the SF device, and wherein the SF device is configured to transmit packets of the terminal device to the first sliced network based on the configuration instruction ETSTI in view of Feder teaches a steering function device that is connected to the user plane via a slice network, as required by claim 1, As a matter of necessary operation, the presence of a slice network between the steering function device and the user plane device requires an interface on the steering function device corresponding to that slice network. ETSI further teaches sending configuration instructions to network functions in order to establish and configure communication interfaces for traffic steering and forwarding. A person of ordinary skill in the art would recognize that, in order to enable the slice between the steering function device and the user plane device, a configuration instruction must be sent to the steering function device to configure the corresponding interface). . Claims 3-4 , 11 – 12, are rejected under 35 USC 103 as being unpatentable over ETSI in view of Feder and in further view of Yang (US 10,530,645) Regarding claim 3, ETSI in view of Feder disclose the method of claim 1, ETSI does not disclose further comprising: obtaining a first service-level agreement (SLA) level based on the service information; and further determining, based on the first SLA level, the first UP device and the first sliced network, wherein the first sliced network meets the first SLA level. However in analogous art Yang discloses: obtaining a first service-level agreement (SLA) level based on the service information (Yang; see e.g. Column 6, Lines 40 – 62: Process 400 may further include provisioning (at 475) resources within edge cloud 110. For example, mSON management device 130 may provision (at 475) the configurable network equipment in edge cloud 110 to provide various centralized control plane, user plane, management (e.g., mobility management, session management, access management, radio resource management, other management services), supplemental services, and/or other functionalities to UE 120 based on the requirements associated with UE 120. mSON management device 130 may alternatively provision (at 475) resources of edge cloud 110 to a set of network slices, and map each network slice to a different target SLA based on services, functionalities, and performance characteristics of the resources provisioned to each network slice. In provisioning (at 475) the resources, mSON management device 130 may select, based access requirements associated with the obtained (at 420) profile, a particular network slice that is mapped to a target SLA that meets or exceed requirements of UE 120 or services requested by UE 120.); and further determining, based on the first SLA level, the first UP device and the first sliced network, wherein the first sliced network meets the first SLA level (Yang; see e.g. Column 6, Lines 40 – 62: Process 400 may further include provisioning (at 475) resources within edge cloud 110. For example, mSON management device 130 may provision (at 475) the configurable network equipment in edge cloud 110 to provide various centralized control plane, user plane, management (e.g., mobility management, session management, access management, radio resource management, other management services), supplemental services, and/or other functionalities to UE 120 based on the requirements associated with UE 120. mSON management device 130 may alternatively provision (at 475) resources of edge cloud 110 to a set of network slices, and map each network slice to a different target SLA based on services, functionalities, and performance characteristics of the resources provisioned to each network slice.

Therefore it would have been prima facie obvious to one of ordinary skill in the art before the effective filing da te of the claimed invention to incorporate Yang’s scheme. The motivation being the combined solution provides for implementing a known technique resulting in increased efficiencies of managing and delivering network traffic. Regarding claim 4, ETSI in view of Feder and in further view of Yang disclose the method of claim 3, further comprising: obtaining a second SLA level; and determining, based on the second SLA level, a second UP device and a second sliced network, wherein the second sliced network is between the second UP device and the SF device, Per dependent claim 3, one of ordinary skill in the art if readily able to implement multiple SLA level elements (1st, 2nd, 3rd, etc.) with respect to the slice networks being in between the other multiple elements comprising UP devices and SF devices. See MPEP 2144.04 Regarding claim 11, claim 11 comprises the same and/or similar subject matter as claim 3 and is considered an obvious variation; therefore it is rejected under the same rationale. Regarding claim 12, claim 12 comprises the same and/or similar subject matter as claim 4 and is considered an obvious variation; therefore it is rejected under the same rationale. Claim 19 is rejected under 35 USC 103 as being unpatentable over ETSI in view of Feder and in further view of Ghadge and in further view of Yang Regarding claim 19, ETSI in view of Feder and in further view of Ghadge disclose the BNG system of claim 17, ETSI does not disclose wherein the gateway management 19. device is further configured to: obtain a first service-level agreement (SLA) level based on the service information; and further determine, based on the first SLA level, the first UP device and the first sliced network, wherein the first sliced network meets the first SLA level. However in analogous art Yang discloses: obtain a first service-level agreement (SLA) level based on the service information information (Yang; see e.g. Column 6, Lines 40 – 62: Process 400 may further include provisioning (at 475) resources within edge cloud 110. For example, mSON management device 130 may provision (at 475) the configurable network equipment in edge cloud 110 to provide various centralized control plane, user plane, management (e.g., mobility management, session management, access management, radio resource management, other management services), supplemental services, and/or other functionalities to UE 120 based on the requirements associated with UE 120. mSON management device 130 may alternatively provision (at 475) resources of edge cloud 110 to a set of network slices, and map each network slice to a different target SLA based on services, functionalities, and performance characteristics of the resources provisioned to each network slice. In provisioning (at 475) the resources, mSON management device 130 may select, based access requirements associated with the obtained (at 420) profile, a particular network slice that is mapped to a target SLA that meets or exceed requirements of UE 120 or services requested by UE 120.); and further determine, based on the first SLA level, the first UP device and the first sliced network, wherein the first sliced network meets the first SLA level information (Yang; see e.g. Column 6, Lines 40 – 62: Process 400 may further include provisioning (at 475) resources within edge cloud 110. For example, mSON management device 130 may provision (at 475) the configurable network equipment in edge cloud 110 to provide various centralized control plane, user plane, management (e.g., mobility management, session management, access management, radio resource management, other management services), supplemental services, and/or other functionalities to UE 120 based on the requirements associated with UE 120. mSON management device 130 may alternatively provision (at 475) resources of edge cloud 110 to a set of network slices, and map each network slice to a different target SLA based on services, functionalities, and performance characteristics of the resources provisioned to each network slice.
