Office Action

§103 §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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 16 January 2025, 14 May 2025 and 29 October 2025 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claims 21-23, 25-26, 28-30, 32-33, 35-37 and 39-40 are rejected under 35 U.S.C. 103 as being unpatentable over US 2014/0240902 by Burch in view of US 2008/0019067 by Reynolds et al. (Reynolds hereinafter). Regarding claim 21, Burch discloses a power distribution unit [see at least Figure 2, (110)] comprising: a plurality of outlet circuits [see at least Figure 2, (140A)-(140D)]; an input interface [see at least Figure 2, (130)]; and a controller [see at least Figure 2, (150)] configured to: receive disconnect priorities associated with the plurality of outlet circuits, assign priority levels to the plurality of outlet circuits according to the disconnect priorities [see at least paragraph 0029; Figure 5, (202)]; and disconnect the plurality of outlet circuits according to the priority levels until a sum current level [see at least Figure 5, (214)] falls below a priority disconnect current threshold [see at least paragraphs 0039-0040].

It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to display the amount of current to allow a user to manage the current draw. Thus, allowing the user to take steps to prevent the circuit from being shut down and allowing the system to remain operational. Regarding claim 38, Burch in view of Reynolds teaches the power distribution system of claim 35. Burch in view of Reynolds fails to teach wherein the power distribution unit is configured to: indicate an amount of current drawn by an outlet circuit selected from the plurality of outlet circuits via a current draw indicator. However, Krieter discloses this limitation [see at least paragraph 0015; claim 6]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to display the amount of current to allow a user to manage the current draw. Thus, allowing the user to take steps to prevent the circuit from being shut down and allowing the system to remain operational. Claims 27 and 34 are rejected under 35 U.S.C. 103 as being unpatentable over US 2014/0240902 by Burch in view of US 2008/0019067 by Reynolds et al.

Burch in view of Reynolds fails to teach wherein the controller is further configured to: indicate, via an indicator, at least one selected from a group consisting of: that a sum current level of the plurality of outlet circuits is approaching a priority disconnect threshold before the sum current level exceeds the priority disconnect threshold; and that a first current level of a first outlet circuit of the plurality of outlet circuits is approaching an individual circuit current threshold before the first current level exceeds the individual circuit current threshold. However, Jones discloses this limitation [see at least paragraph 0070]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to indicate when a current level is approaching the current threshold in order to notify a user. Thus, allowing the user to take steps to prevent the circuit from being shut down and allowing the system to remain operational. Regarding claim 34, Burch in view of Reynolds teaches the method of claim 28. Burch in view of Reynolds fails to teach further comprising: indicating, via an indicator connected to a controller of the power distribution unit, at least one selected from a group of: that a sum current level of the plurality of outlet circuits is approaching a priority disconnect threshold before the sum current level exceeds the priority disconnect threshold; and that a first current level of a first outlet circuit of the plurality of outlet circuits is approaching an individual circuit current threshold before the first current level exceeds the individual circuit current threshold. However, Jones discloses this limitation [see at least paragraph 0070]. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the Applicant's invention to indicate when a current level is approaching the current threshold in order to notify a user. Thus, allowing the user to take steps to prevent the circuit from being shut down and allowing the system to remain operational. 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 21-40 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-22 of U.S. Patent No. 10,158,213 in view of US 2014/0240902 by Burch in view of US 2008/0019067 by Reynolds et al. (Reynolds hereinafter), US 2014/0240902 by Burch in view of US 2008/0019067 by Reynolds et al. (Reynolds hereinafter) in further view of US 2011/0292869 by Krieter and US 2014/0240902 by Burch in view of US 2008/0019067 by Reynolds et al. (Reynolds hereinafter) in further view of US 2010/0305769 by Jones et al. (Jones hereinafter). The claims of Patent 11,158,213 (Patent of US 2014/0240902 used above) disclose most of the limitations of the claims of the present Application. The remaining limitations are disclosed in the other prior art as noted in the rejections above. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Van Akin (US 2010/0007210) discloses a power distribution system. Verges (US 2010/0019575) discloses a power distribution unit with network control.
