Office Action

§102 §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 . This office action is in response to Pre-Amendment filed on Oct. 24, 2023. Claim 1 has been canceled. New claims 2-31 have been added. Claim Objections Claim 25 is objected to because of the following informalities: “The non-transitory computer-readable storage medium of claim 25” should be changed to -- The non-transitory computer-readable storage medium of claim 24 --. Appropriate correction is required. 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 §§ 706.02(l)(1) - 706.02(l)(3) 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 2, 17, 24 and 28 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 23 and 24 respectively of U.S. Patent No. 10,296,843. Although the claims at issue are not identical, they are not patentably distinct from each other because the patent claims include all the limitations of the instant application claims, respectively (see table below). The patent claims also include additional limitations. Hence, the instant application claims are generic to the species of invention covered by the respective patent claims. As such, the instant application claims are anticipated by the patent claims and are therefore not patentably distinct therefrom (See Eli Lilly and Co. v. Barr Laboratories Inc., 58 USPQ2D 1869, " a later genus claim limitation is anticipated by, and therefore not patentably distinct from, an earlier species claim", In re Goodman, 29 USPQ2d 2010, "Thus, the generic invention is 'anticipated' by the species of the patented invention" and the instant “application claims are generic to species of invention covered by the patent claim, and since without terminal disclaimer, extant species claim preclude issuance of generic application claims”). Claims 3-16, 18-23, 25-27 and 29-31 are rejected as being dependent on independent claims 2, 17, 24 and 28. Application 18/491,875 U.S. Patent No. 10,296,843 Claims 2 &17.

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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 2-20, and 24-31 are rejected under 35 U.S.C. 102(1) as being anticipated by Non-Technical Loss Analysis for Detection of Electricity Theft using Support Vector Machines ("Nagi"). Regarding claims 2, 17, 24 and 28, Nagi discloses a method comprising: determining, by one or more processors, signal values for a selected set of signals relating to a plurality of energy usage conditions, wherein the selected set of signals includes a consumption drop signal corresponding to a drop in energy consumption measured by an energy meter compared to an average energy consumption measured by the energy meter (See Nagi; e.g., at Fig. 1; and at P. 909: B.

Support Vector Machine). Regarding claim 7, Nagi further discloses wherein the trained classifier model is further configured to classify, as corresponding to normal energy usage, at least a second portion of the plurality of N-dimensional representations within an allowable N-dimensional proximity from N-dimensional representations which have been previously recognized as corresponding to normal energy usage. (See Nagi; e.g., at Fig. 1: SVM training); Fig. 2: SVM Training and Test Data; and at p. 908: II. Support Vector Machine). Regarding claim 8, Nagi further discloses wherein the trained machine learning classifier model is trained with at least one of a support vector machine, a boosted decision tree, a classification tree, a regression tree, a bagging tree, a random forest, a neural network, or a rotational forest (See Nagi; e.g., at p. 907, col. 2: discloses other ML methods that can be used). Regarding claim 9, Nagi further discloses wherein applying the trained machine learning classifier model to the plurality of N-dimensional representations to identify energy usage conditions associated with non-technical loss comprises: identifying, by the one or more processors, a plurality of energy usage conditions that have likelihoods of being associated with non-technical loss (See Nagi: e.g., p. 909: D.

Regarding claim 16, Nagi further discloses wherein reporting the identified energy usage conditions associated with non-technical loss comprises graphically rendering a report of the identified energy usage condition for presentation by a computer system (See Nagi; e.g., p. 907, 2ⁿᵈ col.: "The approach proposed in this paper provides an intelligent system for assisting TNB inspection teams to increase effectiveness of their operation in reducing NTLs, and detecting fraudulent consumers based on load profiles of customers derived from the customer database. This system will increase fraud detection hit-rate for onsite inspection and reduce operational costs due to onsite inspection in monitoring NTL activities."). Regarding claims 25-27 and 29-31 recite limitations substantially similar to the claims 6-7 and 14. Therefore, these claims were rejected for similar reasons as stated above. Allowable Subject Matter Claims 21-23 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. Regarding 21-23, Nagi discloses all the subject matters above. However, Nagi fails to teach all the limitations in claims 21-23 Examiner's Note: Examiner has cited particular columns and line numbers in the references applied to the claims above for the convenience of the applicant. Although the specified citations are representative of the teachings of the art and are applied to specific limitations within the individual claim, other passages and figures may apply as well.
