Office Action

§103
DETAILED ACTION This Office Action is a response to Applicant's Amendment filed on 5/1/26. By virtue of this amendment, claims 1-19 are currently presented in the instant application. Terminal Disclaimer filed on 5/1/26 improper as follow below. 1. Prior patent 12/200,834 is cited incorrectly. It should read 12,200,834. 2. The terminal disclaimer identifies a party who is not the applicant (only for applications filed on or after September 16, 2012; See FP 14.26.10): For cases filed on/after 9/16/2012, 37 CFR 1.321 specifies that the applicant can disclaim, and the terminal disclaimer must specify the extent of the applicant's ownership. To remedy this: A request under 37 CFR 1.46(c) to change the applicant needs to be filed, which is (1) a request, signed by a 1.33(b) party, (2) a corrected ADS (37 CFR 1.76(c)) that identifies the "new" applicant in the applicant information, and is underlined since it is new, and (3) a 3.73(c) statement showing chain of title to the new applicant. Along with the § 1.46(c) request we need a POA that gives power to the attorney who is signing the TD, along with another copy of the TD, unless they file a TD that is signed by the applicant. Note: The applicant cited on the TD must be cited exactly as it is cited on the ADS and or filing receipt and also in its entirety. If more space for applicant section is required, please use smaller fonts or submit an attachment page to the TD. Please make corrections as suggested above and also resubmit the TD. (No new fee required). Therefore, claims 1-19 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of U.S. Patent No. 12200834. 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. Instant application:18/984,667. 1.

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. Claim 1 is rejected under 35 U.S.C. 103 as being unpatentable over by CN107770923 in view of Sadwick (US Pub. No: 2013/0175931). PNG media_image1.png 678 821 media_image1.png Greyscale PNG media_image2.png 499 819 media_image2.png Greyscale PNG media_image3.png 553 796 media_image3.png Greyscale PNG media_image4.png 575 796 media_image4.png Greyscale With respect to claim 1, CN107770923 discloses a circuit unit (30) for a lamp (figure 4 above), comprising: first power stage (see figure 2 above) configured to receive a first power signal from an Alternating Current (AC) power supply(AC), perform an Alternating Current—Direct Current (AC-DC) conversion on the first power signal to generate a second power signal(figure 2 above and also figure 3 above for AC convert to DC from both rectifiers), and performs a dimming signal conversion on the first power signal(a light modulator(40) which includes a controllable silicon dimmer, page 5) from the Alternating Current (AC) power supply to generate a first dimming signal; and a second power stage(figure 1 above) configured to be connected with the first power stage(figure 2 above) to receive the second power signal output from the first power stage, wherein the second signal output being PWM signal or varied voltage signal, and the first dimming signal both output from the first power stage(figure 2 above), wherein, the second power stage(the lighting modulator(40) which includes the controllable silicon dimmer, page 5) adjusts the second power signal based on at least the first dimming signal to generate a third power signal (figure 2 above), and the second power stage(figure 2 above) provides a light-emitting unit of the lamp(10) with the third power signal to drive the light-emitting unit(10). CN107770923 does not disclose a dimming signal conversion on the first power signal by converting a phase cut angle of the first power signal into dimming depth information to generate a first dimming signal. Sadwick disclose a dimming signal conversion on the first power signal by converting a phase cut angle of the first power signal into dimming depth information to generate a first dimming signal. Paragraph [37] for a dimmer 16 or other type of forward or reverse AC dimmer is fed to a control unit 20 which processes and supplies an appropriate output signal or dimming control signal 14 based on the dimming information/phase angle/etc. provided in a triac dimming signal 18 by the triac dimmer 16 or other types of forward or reverse dimmer. It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate the features of Sadwick into the lamp circuit of CN107770923 to provide a phase cut angle of the first power signal into dimming depth information to generate a first dimming signal. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
