Office Action

§DOUBLEPATENT §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 . The following is a Final Office action in response to communications received on 01/26/2026. Claims 1-20 have been examined. Response to Arguments Applicant's arguments filed on 01/26/2026 have been fully considered but they are not persuasive. As per the applicant’s arguments that U.S. Patent No. 11921846 (hereinafter ‘846 patent) cannot be used as a reference against the instant application since this application is a divisional of the ‘846 patent and presents claims 11-13 and 19 of the ‘846 patent, the examiner respectfully disagrees. In the restriction requirement issued in the parent application 16/835871 (now U.S. Patent No. 11921846), independent claims 1 and 14 were indicated as generic claims and dependent claims 3-6 and 15-16, 7-10 and 17-18, and 11-13 and 19 were indicated as belonging to different species (3-6 and 15-16 as species I, 7-10 and 17-18 as species II and 11-13 and 19 as species III). As stated by the applicant, claims 3-6 and 15-16 were elected while claims of the other two species claims were eventually cancelled. However, dependent claims 3-6 and 15-16 were never incorporated into the independent claims and despite some amendments the independent claims remained generic. Therefore, the generic claims of the ‘846 patent can be used as a reference against the present application and the double patenting rejection issued in the previous office action is valid. 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 1-10 of U.S. Patent No. 11921846 in view of US 10885089 to De Sousa Webber (hereinafter Webber).

In the independent claims US patent no. 11921846 does not teach: a pair of terms and the number of real observations for a term comprising, for each document in a corpus of documents, a number of occurrences of the term in the document. However, Webber teaches: a pair of terms and the number of real observations for a term comprising, for each document in a corpus of documents, a number of occurrences of the term in the document (Webber: column 1, lines 37-55: a method enables the identification of a level of similarity between a user-provided data item and a data item within a set of data documents. The method includes generating, by a parser executing on the first computing device, an enumeration of terms occurring in the set of data documents. The method includes determining, by a representation generator executing on the first computing device, for each term in the enumeration, occurrence information including: (i) a number of data documents in which the term occurs, (ii) a number of occurrences of the term in each data document. Column 4, lines 6-10: The data items within data documents 104 may be words, numeric values, medical analyses, medical measurements, and musical notes. The data items may be strings of any type (e.g., a string including one or more numbers)). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to employ the teachings of Webber in the invention of US patent no. 11921846 to include the above limitations. The motivation to do so would be to identify of a level of similarity between a user-provided data item and a data item within a set of data documents (Webber: column 1, lines 37-39). Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
