§103 §DOUBLEPATENT
CTNF 19/054,624 CTNF 78746 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. This is a response to the Applicants' file on 2/10/25. In virtue of this filing, claims 1-21 are currently presented in the instant application. Information Disclosure Statement The information disclosure statement (IDS) submitted on 7/10/25 is in compliance with the provisions of 37 CFR 1.97 &1.98. Accordingly, the information disclosure statements are being considered by the examiner. Double Patenting 08-33 AIA 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.

Paragraph 52 of Ohashi for the control section 3 includes, as a main component, a microcomputer including a CPU, ROM, RAM, a timer, etc and paragraph [95] and Figure 4 of Lahoud. With respect to claim 19, Ohashi as modified claim 11 above disclose wherein the one or more power circuits drive the one or more light sources using different powers during ON times of at least two of the modulation periods. Paragraph 52 of Ohashi for the control section 3 includes, as a main component, a microcomputer including a CPU, ROM, RAM, a timer, etc and paragraph [95] and Figure 4 of Lahoud. With respect to claim 20, Ohashi disclose wherein the one or more power circuits further receive one or more linear signals, and wherein the one or more control signals are further based on the one or more linear signals. Figures 1-2 and 8. With respect to claim 21, Ohashi disclose wherein when an input to or an output from the one or more light sources is greater than or equal to a pre-determined level, an intensity of light emanating from the one or more light sources is controlled based on the one or more linear signals, and when the input to or the output from the one or more light sources is less than the pre- determined level, the intensity of the light emanating from the one or more light sources is controlled based on the one or more power modulation signals. See claim 7 of Ohashi disclose wherein the spread-code-sequence generation means generates the spread code sequence and increase and decrease spreading factor for the intensity of the near-infrared light beam detect when received by the light receiving means of the light detection section is low or high.
