Office Action

§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 . 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 1-20 of U.S. Patent No. 12518679. Although the claims at issue are not identical, they are not patentably distinct from each other because the systems of this application contains similar structures adequate to perform the functions recited in the patent application. This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. The claims are as follows with the differences highlighted: 19396817 12518679 With reference to claim 1: A scan circuit applicable to driving a plurality of light-emitting-diodes (LED) of a plurality of scan lines of a display panel, comprising: a plurality of switching components, wherein each of the plurality of switching components is electrically connected with one of the plurality of scan lines of the display panel; a plurality of power transistors, disposed corresponding to the plurality of scan lines of the display panel, wherein each of the plurality of power transistors is electrically connected to each of the plurality of scan lines; and a low-dropout regulator circuit, being electrically connected to the plurality of switching components such that a common joint is formed between the low-dropout regulator circuit and the plurality of switching components, and the low-dropout regulator circuit selectively generates an output voltage to at least one of the plurality of scan lines of the display panel through the plurality of switching components. With reference to claim 1: A scan circuit applicable to driving a plurality of light-emitting-diodes (LED) of a display panel, comprising: a plurality of switching components, wherein each of the plurality of switching components is electrically connected with a scan line of the display panel for determining if the plurality of LEDs connected to the scan line are conductive, a plurality of power transistors, disposed corresponding to a plurality of the scan lines of the display panel, wherein each of the plurality of power transistors is electrically connected to each of the plurality of the scan lines; and a low-dropout regulator circuit, being electrically connected to the plurality of switching components such that a common joint is formed between the low-dropout regulator circuit and the plurality of switching components, and the low-dropout regulator circuit selectively pulls up a voltage level of at least one of the scan lines so as to avoid ghosting imaging on the display panel. With reference to claim 7: wherein the low-dropout regulator circuit comprises an operational amplifier, a power switch, an enable switch, a plurality of resistors connected in series and a low-dropout capacitance, a positive terminal of the operational amplifier is adapted to receive a reference voltage, a negative terminal of the operational amplifier is selectively coupled with a joint node of the plurality of resistors connected in series, and an output terminal of the operational amplifier is connected with a gate terminal of the power switch.
