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 . 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 1-16, 21 and 25 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,046,929 in view of Hiramura; (US 2014/0197686). The patent teaches all of the claimed subject matter except for the control assembly detecting a voltage level of each of the battery packs and determining the battery packs having a first highest priority level through the voltage level detected for controlling the switching units being closed to output the highest priority level (claim 1); and wherein, the control unit determining a first voltage difference between a first highest priority level and a second highest priority level of the battery pack being a preset value or substantially a same level for controlling the switching (claim 26). However, Hiramura in the same filed teaches the control assembly detecting a voltage level of each of the battery packs and determining the battery packs having a first highest priority level through the voltage level detected for controlling the switching units being closed to output the highest priority level {claim 3 }; and wherein, the control unit determining a first voltage difference between a first highest priority level and a second highest priority level of the battery pack being a preset value or substantially a same level for controlling the switching (see claim 3). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the patent with the teachings of Hiramura by having the control assembly detecting a voltage level of each of the battery packs and determining the battery packs having a first highest priority level through the voltage level detected for controlling the switching units being closed to output the highest priority level; and wherein, the control unit determining a first voltage difference between a first highest priority level and a second highest priority level of the battery pack being a preset value or substantially a same level for controlling the switching in order to provide battery protection and equal degradation and charge cycles. 1.
