the property of non-volatility associated with a ferroelectric
dielectric layer for a capacitor. Young, however, does not
overcome the innate deficiencies of Chang, Takeshita, and
Waters as discussed above with regard to independent claim 1,
and, therefore, we do not sustain the obviousness rejection of
claim 2.
The rejection of claims 3-21 as unpatentable
over Chang in view of Takeshita, Waters, and Brown.
At the outset, we note that this grouping of claims
includes independent claims 8 and 16 which have electrode
configuration recitations similar to those of previously
discussed independent claim 1. As with the Young reference
discussed above in relation to the rejection of claim 2, Brown
was applied by the Examiner for the limited purpose of
supplying a teaching of utilizing a ferroelectric layer to
generate a rectifying junction penetrating electric field.
Since it is our view that the Examiner has not established a
prima facie case of obviousness with respect to the proposed
combination of Chang, Takeshita, and Waters, the addition of a
ferroelectric material layer taught by Brown does not overcome
the deficiencies of the applied prior art. Accordingly, we
