Office Action

§DP
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, see remarks, filed 11/28/2025, with respect to 103 rejection have been fully considered and are persuasive. The 103 rejection of claims 1-10, 12-16, 18-20 has been withdrawn. See reasons for allowance below. 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.

Allowable Subject Matter Claims 11 and 17 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The combination of Bangalore, Green, and Ingram fails to teach or suggest the features of amended independent claim 1 (e.g., “wherein a selected alternative response is transmittable to a participant in the communication session (CS) that is ongoing; the selected alternative response is transmittable based on a context of the CS for participant-directed message transmission to at least one of the plurality of users participating in the CS.”) Bangalore analyzes utterances but never performs participant-directed transmission within a live CS or uses contextual state to decide when or to whom a response should be sent. Green is even further removed: it ranks objects for search and recommendation and has no disclosure of multi-party communication, no live sessions, and no contextual transmission logic. Ingram delivers content asynchronously using heuristics, not within an active conversation or based on a maintained conversational state. None of the references disclose a persistent conversational context that governs participant-specific message delivery in real time, and nothing in the cited combination would motivate a skilled artisan to retrofit asynchronous targeting or search embeddings into a real-time, context-aware communication architecture. As amended, the claim recites a structural and functional interaction—context-based, participant-directed transmission within an ongoing CS—that is absent from the art and irreconcilable with the teachings of the cited references. Bangalore fails to disclose this limitation. Bangalore focuses on analyzing user utterances to update a conversation context, but does not disclose transmitting a selected response to another participant within an ongoing CS or performing any transmission based on the context of that session. Its comparison of user utterances to conversation history is limited to contextual understanding and does not involve context-dependent message delivery among multiple users. Green describes ranking objects using reconstructed embeddings and personalization scores, but it does not disclose multi-user transmission or contextual communication within an active session. Green’s framework for object relevance is static and focused on search and recommendation—not on participant-directed response transmission during a live conversation. Ingram similarly fails to bridge the gap. Ingram teaches asynchronous targeting and content delivery through heuristics or query strategies, but not real-time or context-coupled communication. Its “quick lookup” mechanism relates to static content targeting, not adaptive, live-session message routing among CS participants. Neither Bangalore, Green, nor Ingram teach or suggest such a real-time, context-driven, participant-directed communication mechanism. Accordingly, the cited combination lacks the structures and logic necessary to render the amended claims obvious. The references do not contemplate transmission within an ongoing session based on contextual state modeling, and thus fail to teach or suggest the claimed invention. Independent claims 8 and 15 recite novel features of the claimed invention and, for at least the reasons set forth above with respect to independent claim 1, the cited references also fails to teach or suggest the features of independent claims 8 and 15. Each of claims 2-7, 9-14, and 16-20 depends, either directly or indirectly, from one of independent claims 1, 8 and 15. Claims 11 and 17 both include similar recitations to the allowable parent applications, claims include "identifying the highly relevant portion from a sub-portion of the one or more likely- relevant portions of the content based on both the relevance threshold and the additional relevance threshold, wherein the sub-portion is associated with the additional relevance threshold that is greater than the relevance threshold". The cited art to Aravamudan discloses "receiving first input intended to identify a desired content item among content items associated with metadata, determining that an input portion has an importance measure exceeding a threshold, and providing feedback identifying the input portion. Abstract and FIG. 4." There is no discussion of a two thresholds such as (1) a relevance threshold; and (2) an additional relevance threshold Input is merely evaluated to determine is a threshold is met. The combination of references is silent on "an additional relevance threshold" (e.g., a determined importance or temporal urgency of a sub-portion of the likely-relevant portion). The cited reference to Baldwin is also silent with regards to (a) an additional relevance threshold; and (b) a highly relevant portion identified based on the additional relevance threshold. As such, the combination of references fails to teach or suggest "identifying the highly relevant portion from a sub-portion of the one or more likely-relevant portions of the content based on both the relevance threshold and the additional relevance threshold, wherein the sub-portion is associated with the additional relevance threshold that is greater than the relevance threshold." Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
