Office Action

§102 §103
DETAILED ACTION 1.This communication is in response to the amendment filed on 01/22/2026. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 1a. Status of the claims: Claims 1 and 20 are amended. Claims 1- 20 are pending. Response to Arguments 2. Applicant's arguments filed 1/22/2016 have been fully considered but they are not persuasive. A, Applicant argues that “The Office Action appears to equate "user experience" levels (e.g., a user's political view or subject matter expertise) with the recited "operations information about the network service." As shown by the disclosure above, however, Nguyen teaches sharing user context to customize a chat bot's personality or knowledge base . It does not disclose receiving "operations information" regarding the network service itself (e.g., network diagnostics, device status, or topology). In fact, nothing in Nguyen appears to teach any consideration about network service operations or any information pertaining thereto. A POSITA would not understand a user's "experience level" with a topic to teach or suggest information about the operation of the network service," as recited in claim 1. (Remarks, page 9). In response to A, The Examiner disagrees because Nguyen’s “a list of user experience, respective problem, solutions with the shared AI chat bot running in a network system” reasonably interpreted as being “operations information about the network service. This interpretation is based on the specification that discloses in paragraph [0022] that “some embodiments can integrate a chat engine into the provider's analytic system to enhance the provider's field operations and services, generate natural and actionable chat insights, reports and surveys for the provider and/or the user, provide the user with self-help suggestions and/or promotion of operator services (e.g., via a chat interface), improve chat accuracy and relevancy for analytic applications.” Based on this the specification of the instant application it is reasonable to conclude that a list of user experience, respective problem, solutions with the shared AI chat bot running in a network system” could be reasonably interpreted as being “operations information about the network service. B, Applicant argues that Nguyen does not disclose “The cited portions of Nguyen are reproduced above, and nothing in that text appears to teach or suggest performing any functions related to enhancing a prompt. Instead, Nguyen teaches that the model itself is updated using parameters from another model. Thus, the Office Action appears to equate updating model parameters (weights) with "generating an enhanced chat prompt." As shown by the disclosure above, however, Nguyen uses the shared data to modify the internal weights of the neural network itself . Nguyen does not generate a text-based "chat prompt" that is then transmitted to a separate engine. A POSITA would understand that the weights of a model are internal features of the model and that a chat prompt is an external stimulus provided to the model. These internal weights are then used to generate tokens in response to the prompt. Nguyen specifically teaches that the response is improved by changing weights, not that any action is performed with regard to the user's chat prompt itself. In other words, modifying the "brain" of a model is technically distinct from generating an "enhanced prompt" to be processed by that model," as recited in claims 1 and 12. (Remarks, page 11). In response to B, The Examiner disagrees in addition that what was stated in section A, Nguyen discloses in [0015 ] generating an updating chat bot by way of interaction with AI chat bot by using a machine learning model based on a list of user experiences, respective problems, solutions with the shared AI chat bot using a software ( logic is equated to software bases on specification [0030] that discloses logic can be software or hardware circuitry),; by interaction with a user using the detailed information the chat prompt is enhanced). Based on the specification [0023] that discloses that “The term, "chat prompt," as used herein, means any text or data that can be provided, e.g., to a chat engine to prompt a response, including without limitation a user query provided by a user. Å "response" is any response received from the target of a chat prompt (e.g., a chat engine) that is, or purports to be, responsive to the chat prompt. An "enhanced" chat prompt or response is a chat prompt or response, respectively, that has been enhanced by any of the techniques described herein, e.g., by adding information or context to a user query (or any other chat prompt) and/or response that increases the probability of a relevant and/or actionable response ultimately being returned to the user. As used herein, the term "operations information" can include any information about the network (or other) service being provided, including without limitation,” . How can be seen action by a user in Nguyen ‘s reference could be equated to any action is performed with regard to the user's chat prompt itself. Therefore, the claim limitation is disclosed by Nguyen. C, Applicant argues that Nguyen does not disclose “logic to transmit the enhanced chat prompt, through the network interface for processing general purpose conversational artificial intelligence." Nguyen, by contrast, processes the query locally using the updated specific chat bot model," as recited in claim 1. (Remarks, page 12). In response to C, The Examiner disagrees because Nguyen does teach an enhanced prompt from one ML engine to another because Nguyen, [0015] providing interaction with AI chat bot using a user interface by improving conversation in a AI chat bot system by providing details in a conversation specific topic of interest using a machine learning model using a software ( logic is equated to software bases on specification [0030] that discloses logic can be software or hardware circuitry); by interaction with a user using the detailed information the chat prompt is enhanced)). The interpretation of the Examiner is based on the specification [0023] that states “The term, "chat prompt," as used herein, means any text or data that can be provided, e.g., to a chat engine to prompt a response, including without limitation a user query provided by a user. Å "response" is any response received from the target of a chat prompt (e.g., a chat engine) that is, or purports to be, responsive to the chat prompt. An "enhanced" chat prompt or response is a chat prompt or response, respectively, that has been enhanced by any of the techniques described herein, e.g., by adding information or context to a user query (or any other chat prompt) and/or response that increases the probability of a relevant and/or actionable response ultimately being returned to the use. ” D, Applicant argues that Nguyen does not disclose “Nguyen does not teach or suggest that the updated chat bot receives any response generated by another chat bot, let alone that the updated chat bot might enhance such a received response. Nguyen teaches using a second model to generate the initial response. It does not teach receiving a generated response and then subjecting it to a post-processing enhancement by a different ML engine. Thus, while claim 1 recites a multi-stage pipeline with enhancement of both the initial prompt from the user and the initial response from a general-purpose model, Nguyen teaches a single-stage generation using an updated model," as recited in claims 1. (Remarks, page 12). In response to D, The Examiner disagrees Nguyen does teach or suggest that the updated chat bot receives any response generated by another chat bot, Nguyen also teaches the updated chat bot might enhance such a received response. Nguyen teaches in [0015] (providing interaction with AI chat bot using a user interface by improving conversation in a AI chat bot system by providing details in a conversation specific topic of interest using a machine learning model using a software ( logic is equated to software bases on specification [0030] that discloses logic can be software or hardware circuitry), Nguyen, [0015]; by interaction with a user using the detailed information the chat prompt is enhanced)). Based on the specification [0023] that discloses that “The term, "chat prompt," as used herein, means any text or data that can be provided, e.g., to a chat engine to prompt a response, including without limitation a user query provided by a user. Å "response" is any response received from the target of a chat prompt (e.g., a chat engine) that is, or purports to be, responsive to the chat prompt. An "enhanced" chat prompt or response is a chat prompt or response, respectively, that has been enhanced by any of the techniques described herein, e.g., by adding information or context to a user query (or any other chat prompt) and/or response that increases the probability of a relevant and/or actionable response ultimately being returned to the user. As used herein, the term "operations information" can include any information about the network (or other) service being provided, including without limitation,” Finally Nguyen teaches in [0104] the IA model can be made of multi engines. Therefore, Nguyen teaches the claim limitations. E, Applicant argues that “, Nguyen does not teach or suggest multiple features of claim 1 and cannot anticipate that claim. The Office Action does not allege that any of the other Cited References remedy these deficiencies of Nguyen," as recited in claim 1. (Remarks, page 13). In response to E, The Examiner disagrees because as it was stated section above Nguyen discloses the claim limitation. F, Applicant argues that Ingah does not teach or suggest “modifying a configuration of CPE "based at least in part on the enhanced response," as claim 2 requires “ as follows: The Office Action appears to equate restoring a backup with "modifying a configuration... to improve performance." As shown by the disclosure above, however, Ingah teaches a system for backing up and restoring static configuration settings (e.g., replacing an old modem with a new one). Ingah does not teach or suggest modifying a configuration of CPE "based at least in part on the enhanced response," as claim 2 requires. Ingah teaches modifying a configuration based on a user's direct command to restore a configuration. In fact, Ingah teaches nothing about the use of ML for any purpose," as recited in claim 2. (Remarks, page 14). In response to F, The Examiner disagrees because Ingah discloses in [0127]; [0128] customer premises equipment is configured with a changed configuration, that is a retrieved and stored configuration that has the customer premises equipment that is computers and device associated with a user , by configuring the device with the retrieved and stored configuration, the default configuration is changed to an improved configuration that is based on the configuration settings of a customer premises equipment . G, Applicant argues that “Nguyen does not teach or suggest modification of any CPE based on anything, let alone an enhanced response from an ML model (setting aside the fact that, as noted above, Nguyen does not teach enhancing a received response at all). Nguyen teaches a personalized chat system that has nothing to do with modifying any kind of hardware," as recited in claim 2. (Remarks, page 14). In response to G, The Examiner disagrees Ingah discloses in [0127]; [0128] that customer premise equipment is changed based on customer by doing so a default configuration of the customer premise equipment is improved by changing the default configuration to a configuration based on the settings of the premise of the user equipments. H, Applicant argues that “the combination of Nguyen and Ingah does not teach or suggest "operations information comprises performance information" or "modify a configuration... to improve performance," as required by claim 2, and the Office Action therefore does not establish that claim 2 is prima facie unpatentable under § 103," as recited in claim 2 . (Remarks, page 8). In response to H, In response to 3G, In response to applicant’s argument that there is no teaching, suggestion, or motivation to combine the references, the examiner recognizes that obviousness may be established by combining or modifying the teachings of the prior art to produce the claimed invention where there is some teaching, suggestion, or motivation to do so found either in the references themselves or in the knowledge generally available to one of ordinary skill in the art.
