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(s) 13 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Application Publication 2020/0303444 A1 to Onuki et al.
With respect to claim 13 Onuki discloses, in Fig. 1A-16C, the photoelectric conversion apparatus according to claim 9 (see above), wherein: the pixels only have one photodiode per pixel readout circuit (See Fig. 2D) but Onuki states the pixels should not be limited to this arrangement (paragraph 132-133).
That is Onuki does not expressly disclose the first pixel and the second pixel each have a first photoelectric conversion element configured to generate a first charge in response to incident light, a first transfer transistor configured to transfer the first charge, a second photoelectric conversion element configured to generate a second charge in response to incident light, and a second transfer transistor configured to transfer the second charge; and the control circuit controls the pixel control circuit such that, during the single frame, a period in which the first transfer transistor and the second transfer transistor included in the first pixel are on during the first period overlaps at least partially with a period in which the first transfer transistor and the second transfer transistor included in the second pixel are on during the second period.
However, the structure of this claim can be satisfied if Onuki had a shared pixel readout for two or more photodiodes. These pixel types are well known and expected in the art to the point where they have their own classification symbol (H04N25/778). (note: the additional claim limitations are a manner of operating the device, see MPEP 2114)
Therefore, Official Notice (MPEP § 2144.03) is taken that both the concepts and advantages of providing multiple photodiodes for a single pixel that then share a source follower and have transfer transistors for each photodiode are well known and expected in the art. Before the effective filing date of the claimed invention, it would have been obvious to one with ordinary skill in the art to have included such a pixel as it would merely be a simple substitution of one known element for another to obtain predictable results.
Claim 14 is rejected for similar reasons as claim 13 above with respect to wherein a pixel included in the pixel array has a plurality of photoelectric conversion elements configured to generate charge in response to incident light
Onuki does not express disclose the memory array retains the analog signal corresponding to a charge obtained by adding a plurality of charges respectively generated by the plurality of photoelectric conversion elements (i.e. binning pixels). However, binning pixels is a manner of operating a circuit as the claim does not further limit the structure in anyway the Examiner has no reason to believe the claimed structures are not provided for the binning functionality as you would merely need to read out both stored signals at the same time (i.e. See above discussion as related to MPEP 2114 about the manner of operating a device distinguishing over the art). However, should there be inherent required structures the examiner is overlooking Official Notice (MPEP § 2144.03) is taken that both the concepts and advantages of binning pixel signals in memory circuits of an imager are well known and expected in the art. Before the effective filing date of the claimed invention, it would have been obvious to one with ordinary skill in the art to have included such a pixel as it would merely be a simple substitution of one known element for another to obtain predictable results.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
U.S. Patent Application Publication 2019/0297287 A1 to Oka et al which also discloses three stacked substrates where the top is a pixel array, middle is a memory and bottom has and ADC.
