Priority Acknowledgment is made of applicant's claim for foreign priority under 35 U.S.C. 119(a)-(d). The certified copy of Japanese patent application number 2018-143491, filed on July 31, 2018, has been received and made of record in parent US Application No. 17/261,059. Information Disclosure Statement The information disclosure statements (lDS) submitted on November 21, 2024 and June 3, 2025 are in compliance with the provisions of 37 CFR 1.97 and have been 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The 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.

In view of the foregoing, claims 1, 17, and 20 of the pending application are an obvious variant and encompassed by claims 5-6 of US Patent 11,482,550. Regarding claims 2-3 and 6-7 : With respect to claims 2-3 and 6-7 , these claims further include limitation that “the transfer section includes a first transfer transistor and a second transfer transistor”, “the first portion is a trench gate of the first transfer transistor, and wherein the second portion is a trench gate of the second transfer transistor”, “the first portion has a maximum width at the front surface of the semiconductor layer, and wherein the second portion has a maximum width at the front surface of the semiconductor layer”, and “a width of the first portion decreases with increasing distance from the front surface of the semiconductor layer, and wherein a width of the second portions decreases with increasing distance from the front surface of the semiconductor layer”, respectively. In analogous art, Nakagawa (WO 2018198486 A1) discloses that a width (i.e., diameter) of the first transistor trench gate and a width (i.e., diameter) of the second transistor trench gate each have a portion that is widest at the front surface, and decreases toward the back surface from the front surface (paragraphs 0007, 0033, 0037, 0043, and figure 13: 125, 126; the gates 125 and 126 are tapered). Nakagawa teaches that the use of a width of the first transistor trench gate and a width of the second transistor trench gate, that each have a portion that is widest at the front surface, and decreases toward the back surface from the front surface is preferred in order to increase the transfer efficiency (paragraphs 0037, 0043). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include a width of the first transistor trench gate and a width of the second transistor trench gate, that each have a portion that is widest at the front surface, and decreases toward the back surface from the front surface is preferred in order to increase the transfer efficiency, in order to increase the transfer efficiency, as suggested by Nakagawa. Regarding claims 4-5 : With respect to claims 4-5 , these claims further include limitation that “the first trench gate is connected to a first drive signal line, and wherein the second trench gate is connected to a second drive signal line”, and “the first transfer transistor and the second transfer transistor are configured to be driven independently of one another”, respectively. In analogous art, Nakagawa (WO 2018198486 A1) discloses that the first trench gate is connected to a first drive signal line, and wherein the second trench gate is connected to a second drive signal line, and that the first transfer transistor and the second transfer transistor are configured to be driven independently of one another (paragraph 0052, and figure 15). Nakagawa teaches that having the first trench gate connected to a first drive signal line, and the second trench gate connected to a second drive signal line, and the first transfer transistor and the second transfer transistor being configured to be driven independently of one another is preferred in order to make it possible to change or adjust the transfer path according to the timing and voltage (paragraph 0052, and figure 15). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include the first trench gate connected to a first drive signal line, and wherein the second trench gate is connected to a second drive signal line, and the first transfer transistor and the second transfer transistor are configured to be driven independently of one another, in order to make it possible to change or adjust the transfer path according to the timing and voltage, as suggested by Nakagawa. Regarding claims 8, 9, and 11 : With respect to claims 8, 9, and 11 , these claims further include limitations that “the single transfer destination is an electric charge-voltage converter”, “the single transfer destination is an electric-charge-voltage holding section”, and “the single transfer destination is a floating diffusion”, respectively.

The use of a an electric charge-voltage converter and/or floating diffusion as a transfer destination is well known in the art in order to allow the pixel signals to be read out of the image senor. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include a transfer destination that is an electric charge-voltage converter and/or floating diffusion, in order to readout the pixel signals, as is common in the art. Regarding claim 12 : With respect to claim 12 , this claim further include limitations that “the photoelectric converter is a photodiode”. In analogous art, Nakagawa (WO 2018198486 A1) discloses the use of an imaging device in which the photoelectric converter is a photodiode (paragraph 0026, and figure 2-3: 200). The use of a photodiode is well known in the art in order to convert incident light into an electric signal. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include the use of a photodiode, in the art in order to convert incident light into an electric signal, as is common in the art. Regarding claim 13 : With respect to claim 13 , this claim further include limitations that “the back surface of the semiconductor layer is a light incident surface”. Official Notice is taken that the concepts and advantages of imaging device in which the back surface of the semiconductor layer is a light incident surface are notoriously well known and expected in the art in order to improve image sensing efficiency since the incident light is not blocked by the wiring formed on the front surface. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to form the back surface of the semiconductor layer as the light incident surface, in order to improve image sensing efficiency since the incident light is not blocked by the wiring formed on the front surface, as is well known in the art. Regarding claim 15 : With respect to claim 15 , this claim further include limitations that “the transfer section at least partially overlaps the photoelectric converter in a plan view”. In analogous art, Yi et al. (US Pub. 2014/0252420) discloses the use of an imaging device in which the transfer section at least partially overlaps the photoelectric converter in a plan view (paragraph 0042, and figure 2A-2C: 22, PD; each of the trench gates 22, that extend into the substrate, overlap with the photodiode PD in the plan view). The overlapping of gates and photodiodes is commonly used in the art in order to efficiently transfer the charge out of the photodiode. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include the overlap of the transfer section with the photoelectric converter in a plan view, in order to efficiently transfer the charge out of the photodiode, as is common in the art. Regarding claim 18 : With respect to claim 18 , this claim further include limitations “an insulating layer is disposed between the first portion and the semiconductor layer, between the first portion and the photoelectric converter, between the second portion and the semiconductor layer, and between the second portion and the photoelectric converter”.

The use of insulating layers are well known in the art in order to prevent charge leakage/transfer between components. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include an insulating layer is disposed between the first portion and the semiconductor layer, between the first portion and the photoelectric converter, between the second portion and the semiconductor layer, and between the second portion and the photoelectric converter, in order to prevent charge leakage/transfer between components, as is common in the art. Regarding claim 19 : With respect to claim 19 , this claim further include limitations that “a light shielding section surrounds the photoelectric converter”. Official Notice is taken that the concepts and advantages of imaging device which includes a light shielding section surrounds the photoelectric converter are notoriously well known and expected in the art in order to control the incident light level to the photosensitive area, as well as to prevent incident light from reaching peripheral circuitry which may cause noise. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to include a light shielding section surrounds the photoelectric converter, in order to control the incident light level to the photosensitive area, as well as to prevent incident light from reaching peripheral circuitry which may cause noise, as is well known in the art . 08-34 AIA Claim s 1-9, 11-13, 15, and 17-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 5-6 of U.S. Patent No. 12,230,654 in view of Nakagawa (WO 2018/198486; the Examiner also notes that for purposes of examination, the Examiner will refer to the machine translation), and Yi et al.
