Appeal No. 95-4788
Application 07/996,393
controlling the amplification factor of the driver so as to produce a smaller amplitude of the clock
pulses used to sweep the residual charges than for the clock pulses used to transfer the charge
signals specified in claim 3" (Brief, page 9). The examiner's reasoning that "it would have been
obvious . . . to control the variations in the prior art clock pulse voltages in accordance with the
dual-voltage control means disclosed in Howard et al. in order to provide different clock voltages
for the respective sweep and transfer functions of a solid state imaging device so that more control
could be exercised over minimizing the thermal noise generated by these pulses" (Examiner's
Answer, page 5) does not provide any factual support for the reasoning that one skilled in the art
would have sought to minimize the thermal noise by controlling the amplitude of the clock pulses.
For the reasons stated above, the rejection of claims 3-5 is reversed.
