Office Action

§102 §103
DETAILED ACTION 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 . Response to Arguments Applicant's arguments filed 06/23/2026 have been fully considered but they are not persuasive. Examiner has thoroughly reviewed applicant’s arguments but firmly believes the cited reference to reasonably and properly meet the claimed limitations i.e. that “receiving data generated by a diagnostics application hosted by a wireless user device that characterizes user behavior”. Examiner respectfully direct the Application to paragraphs 0052, 0054, Zhu et al where disclose that an application launch procedure, the status request may indicate (select) a preferred network slice e.g., a slice class identifier, QoS requirements, etc. (i.e., characterizes user behavior) for application 310. MNO utility application 210 may respond to the status request using status API 420 with subscription information indicating whether or not the user has a current subscription to the requested slice. Further the applicant argues one page 7, the cited art does not anticipate correlating the user behavior to a wireless network slice that the user device is not authorized to use as recited by claim 1. Examiner respectfully disagrees with this argument. In response, examiner would like to point out that in paragraph 0054 Zhu et al disclose, UE included MNO utility application 210 may retrieve subscription plan options for presentation to the user and confirm entitlement with IAMP 226 and ¶ 0055, UE included client application 310 may request presentation (displaying) of icon 408 when the application is using the premium network slice and application activities e.g., game conditions (i.e., characterizes user behavior) do not require a premium network slice QoS. ¶ 0064, upon determining that a user does not have a subscription for a preferred network slice and ¶ 0083, the requested slice is not available (i.e., user device is not authorized) and ¶ 0018, one or more network slices 112 may be configured to provide premium services e.g., low latency, high QoS, etc. for which a user subscription is required. For example, for optimal performance, an app 108 e.g., a real-time gaming app, etc. on UE 102 may require guaranteed low latency that is not available over standard network connections. If a user/subscriber does not have a subscription to a particular network slice e.g., a network slice providing premium service (i.e., user device is not authorized), an application e.g., app 108 cannot use that network slice. The applicant also argues one page 7, the cited art does not anticipate generating a slice notification that identifies the wireless network slice as recited by claim 1. In response, examiner would like to point out that in paragraph 0032 Zhu et al disclose, the particular field may include an existing PCO/ePCO container or a PCO/ePCO container dedicated to include information indicating a user's slice subscription status. The PCO/ePCO message may be generated by a network device in core network, ¶ 0053, MNO utility application 210 may respond to the subscription request using subscribe API 420 by generating menu 404 (i.e., generating a slice notification) to prompt 424 the user to provide user input to approve or deny the requested premium network slice subscription. The applicant argues one page 8, the cited art does not anticipate delivering the slice notification to the wireless user device wherein the wireless user device receives and displays the slice notification as recited by claim 1. In response, examiner would like to point out that in paragraph 0053 Zhu et al disclose, MNO utility application 210 may respond to the subscription request using subscribe API 420 by generating menu 404 (i.e., generating a slice notification) to prompt 424 (displaying) the user to provide user input to approve or deny the requested premium network slice subscription, ¶ 0046, 0064, UE included MNO utility application 210 are integrated into client application 310, application 310 may interact with an entitlement server e.g., on IAMP 226 to present (displaying) network slice subscription/purchase options to the user. ¶ 0065, determining if the new slice subscription is approved (block 530, fig. 5). For example, client application 310 may detect if the user input provides an affirmative response to get a slice subscription and if the provider network authorizes the subscription. If a new slice subscription is approved (block 530—Yes), process 500 may include receiving authorization for the requested network slice and establishing a PDU session with the requested network slice (block 535). For example, upon a successful subscription upgrade. Additionally, the examiner has given the claim language its broadest reasonable interpretation. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Anticipatory reference need not duplicate, word for word, what is in claims; anticipation can occur when claimed limitation is “inherent” or otherwise implicit in relevant reference (Standard Havens products Incorporated v. Gencor Industries Incorporated, 21 USPQ2d 1321). Applicant always has the opportunity to amend the claims during prosecution, and broad interpreted by the examiner reduces the possibility that the claim, once issued, will be interpreted more broadly than is justified. In re Prater, 415 F.2d 1393, 1404-05, 162 USPQ 541, 550-51 (CCPA 1969). Therefore, the previous rejection is maintained. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

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. 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. Claim(s) 4-6, 11-13 and 18-20 are rejected under 35 U.S.C. 103 as being unpatentable over Zhu et al (20240205728) in view of YANG (20230081061). Regarding claims 4-6, Zhu et al discloser, ¶ 0012, the URSP framework provides traffic steering rules for the UE device and enables the UE device to determine how a certain application should be handled in the context of traffic routing to an appropriate network slice, ¶ 0043, a client application 310 may include a video streaming application, a web browser, a gaming application, etc. Some client applications 310 may require relatively high uplink and/or downlink throughput/bandwidth for an optimal user experience. Such client applications 310 make use of network slicing, and, more particularly, a network slice 112 providing premium services. Other client applications 310 may not have requirements for any particular network slice and may generate data processed as default Internet traffic. Client application 310 may include application logic 312 and a slicing subscription client DSSC 314. Regarding claims 4, 11 and 18, Zhu et al does not specifically disclose in detail, application usage, application type. In the same field of endeavor, YANG discloses, in more detail, application usage, application type, uplink data volume, and downlink data volume (¶ 0032-0033 and 0044). Therefore, before the effective filing date of the claim invention, it would have been obvious to one of ordinary skill in the art at the time the invention was made to modify the device of Zhu et al by specifically adding feature in order to enhance system performance to the method enables realizing network slice selecting process according to actual requirement of the application program in flexible and accurate manner so as to effectively improve network use experience of a user as taught by YANG. Regarding claims 5, 12 and 19, Zhu et al does not specifically disclose in detail, categorizing the wireless user device based on the application usage, application type. In the same field of endeavor, YANG discloses, in more detail, categorizing the wireless user device based on the application usage, application type, uplink data volume, and downlink data volume and selecting the wireless network slice based on the categorization (¶ 0031-0033 and 0044). Therefore, before the effective filing date of the claim invention, it would have been obvious to one of ordinary skill in the art at the time the invention was made to modify the device of Zhu et al by specifically adding feature in order to enhance system performance to the method enables realizing network slice selecting process according to actual requirement of the application program in flexible and accurate manner so as to effectively improve network use Regarding claims 6, 13 and 20, Zhu et al does not specifically disclose in detail, wherein the categorization associates a user type with a wireless network slice type. In the same field of endeavor, YANG discloses, in more detail, wherein the categorization associates a user type with a wireless network slice type (¶ 0031-0033 and 0044). Therefore, before the effective filing date of the claim invention, it would have been obvious to one of ordinary skill in the art at the time the invention was made to modify the device of Zhu et al by specifically adding feature in order to enhance system performance to the method enables realizing network slice selecting process according to actual requirement of the application program in flexible and accurate manner so as to effectively improve network use experience of a user as taught by YANG.
