Office Action

§DP
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 . 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 Amendment This Action is responsive to the Applicant’s Amendment/Remarks filed on 01/06/2026. In the Amendment, applicant amended claims 1, 8 and 15. As necessitated by the Amendment, Examiner hereby respectfully withdraws 35 U.S.C § 101 rejections to claims 1-20. As to Arguments and Remarks filed in the Amendment, please see Examiner’s responses shown after Rejections - 35 U.S.C § 103. Please note claims 1-20 are pending. Information Disclosure Statement The information disclosure statement (IDS) filed on 11/26/2025 has been considered (see form-1449, MPEP 609). 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The 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/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 12,222945.

Case will be allowed upon receive a terminal disclaimer. Additional Art Considered The prior art made of record and not relied upon is considered pertinent to the Applicants’ disclosure. The following patents and papers are cited to further show the state of the art at the time of Applicants’ invention with respect to federate queries across multiple data stores which spans the data stores by defining the entities and relationships and inferring the intent of the queries to optimize data searches in the individual data stores. A. Shimizu et al. (US PGPUB 2016/0154848, hereafter Shimizu); “Database Management Apparatus, Database Management Method, And Storage Medium” disclose “database management which comprising a query acceptance unit which accepts a query to the database; a query execution plan generating unit which generates a query execution plan which includes a database operation which is necessary for executing the accepted query; and a query execution unit which, in executing the accepted query on the basis of the generated query execution plan, dynamically generates a task for executing the database operation, and executes the dynamically generated task. The query execution unit acquires a resource usage state, and, when executing the next database operation, generates a new task on the basis of the resource usage state, and executes the new task in parallel with the task”. Shimizu also teaches a plurality of queries, the context may be identified based on a transaction ID, a user ID, a schema ID, and the like, and the order in which the tasks are generated may be changed based on the priority of each query [0329]. Shimizu further teaches performance data table and selects the storage having the smallest count [0242], [0247]. B. Pal et al. (US PGPUB 2018/0089306, hereafter Pal); “Query Acceleration Data Store” disclose “utilize a query acceleration data store which query processing scheme for obtaining and processing the set of data is defined. First partial results of the query stored in a data store are identified, with the first partial results corresponding to a first portion of the set of data. One or more partitions are dynamically allocated to obtain a second portion of the set of data from different data sources”. Pal also teaches query was distributed, search data stores associated with them for events that are responsive to the query. To determine which events are responsive to the query, the indexer searches for events that match the criteria specified in the query [0301]. Pal further teaches collect all the time-ordered partial search results from its source avoids the added need to distribute the time-ordered partial search results between worker nodes to reconstruct the overall time orderliness of the partial search results [0506]. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
