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.

Regarding claim 11 Fujimori et al further discloses of applicant’s A non-transitory computer-readable storage medium configured to store a computer program comprising instructions for executing a photoelectric conversion process of performing photoelectric conversion in a plurality of pixels each including a sensor portion configured to emit a pulse corresponding to an incident photon, a counter configured to count the number of pulses, and a memory configured to store a count value of the counter, the photoelectric conversion process comprising: generating a signal based on a difference in the count value of the counter between at a start timing and at an end timing of an accumulation period; and outputting the signal generated in a first accumulation period between an end of the first accumulation period and an end of a second accumulation period, the first accumulation period and the second accumulation period being included in a full frame period, the first accumulation period being shorter than the second accumulation period (claim 16, A non-transitory computer-readable storage medium configured to store a computer program for a photoelectric conversion device comprising instructions for executing following processes, wherein the photoelectric conversion device includes a plurality of pixels each including a photoelectric conversion unit that emits pulses corresponding to photons, a counter that counts the number of the pulses, and a memory that stores a count value of the counter; the computer program comprising instructions for executing following processes: generating a signal based on a difference between a count value of the counter at the start of an accumulation period and a count value at the end of the accumulation period; performing control so that a signal generated in a first accumulation period is output between the end of the first accumulation period and the end of a second accumulation period, and one full frame period includes the first accumulation period and the second accumulation period longer than the first accumulation period). Claims 1 – 11 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 3 – 6, and 8 - 12 of copending Application No. 18,669,610, Saito et al in view of Numata US Publication No. 2022/0120610. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims in this application are boarder than the claims in Saito et al 18,699,610. This is a provisional nonstatutory double patenting rejection. Regarding claim 1 Saito et al discloses of applicant’s A photoelectric conversion device comprising: a plurality of pixels each including: a sensor portion configured to emit a pulse corresponding to an incident photon; a counter configured to count the number of pulses; and a memory configured to store a count value of the counter; one or more memories storing instructions; and one or more processors executing the instructions to generate a signal based on a difference in the count value of the counter between at a start timing and at an end timing of an accumulation period, and output the signal generated in a first accumulation period between an end of the first accumulation period and an end of a second accumulation period, the first accumulation period and the second accumulation period being included in a full frame period, the first accumulation period being shorter than the second accumulation period (claim 1, A photoelectric conversion device comprising: a plurality of pixels each including a sensor unit that emits pulses according to incident photons, and a counter that counts the number of pulses; one or more memories storing instructions; and one or more processors executing the instructions to: generate a signal based on a difference between a count value of the counter at the start of an accumulation period and a count value of the counter at the end of the accumulation period, perform control so that a signal generated during the first accumulation period are output between the end of the first accumulation period and the end of a second accumulation period, the first accumulation period and the second accumulation period being included in a full frame period, and the first accumulation period being shorter than the second accumulation period; Saito et al discloses photoelectric conversion device with a counter that counts the photo pulses but does not expressively disclose a memory is configured to store a count value of the counter; Numata teaches a memory storing a count value. Numata teaches of Fig. 1 – 9 of applicant’s a memory is configured to store a count value of the counter (paragraph 0038, FIG. 6 illustrates a clock 600, a timing 601 when the photon is detected by the first counter circuit 211, the count value 602 of the first counter circuit 211 is stored in the memory 214 such that a memory 214 is configured to store a count value 602 of the counter 211). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the circuitry of Saito et al in a manner similar to Numata. Doing so would result improving Saito et al invention in a similar way as Numata – namely the ability to provide a memory storing a count value, in Numata invention, to the photoelectric conversion device with a counter that counts the photo pulses in Saito et al invention. Regarding claim 2 of the combination of Saito et al in view of Numata, Saito et al further discloses of applicant’s wherein the first accumulation period and the second accumulation period overlap each other (claim 3, wherein the first accumulation period and the second accumulation period overlap each other).
