unpersuasive appellant’s argument [principal brief - page 9]
that both Rodriguez and Short are directed to monolithic
capacitors while the instant invention is directed to
integrated circuits. Column 1, lines 10-15, of Rodriguez,
indicating a desire for miniaturization of components within
printed circuits, would clearly have led the skilled artisan
to apply the Rodriguez teachings to integrated circuits.
The examiner’s rationale for the stated rejection is, in
toto:
Rodriguez teaches a typical capacitor structure
having a pair of electrodes of a material “that will
not melt or oxidize” such as platinum or palladium
surrounding an oxygen containing dielectric such as
barium strontium titanate (see columns 2-3).
Although Rodriguez teaches a material “that will not
melt or oxidize”, it is well-known to those of
ordinary skill in the art that platinum or palladium
do in fact oxidize externally. Short is cited as
showing titanates are commonly supplied with oxygen
additives. Rodriguez being cited in Short, the
references are considered an analogous combination
[answer - page 3].
Thus, the examiner employs Rodriguez for a teaching of
the use of materials which will not oxidize when the point of
the instant invention, as claimed, is to use materials which
will oxidize so as to prevent reduction, i.e. loss of oxygen,
of the dielectric which is composed of materials which do
