Appeal No. 95-2138
Application 07/852,078
structure of ferroelectric thin film. Appellants further teach
on pages 7 and 8 that modulated layers are alternating layers of
PZT and PT. Furthermore, we note that Appellants= Figures 4 and
6 show alternating layers of PZT and PT. Thus, we find that the
Appellants= usage of modulated PZT and PT heterostructure
ferroelectric thin film refers to the alternating layers of PZT
and PT illustrated in Figures 4 through 6 and as described on
pages 4 through 10 of the specification.
We fail to find any suggestion to modify Swartz to provide a
ferroelectric thin film structure comprising a substrate and
alternating layers of PZT and PT heterostructure ferroelectric
thin film formed on the substrate. Since there is no evidence in
the record that the prior art suggested the desirability of such
a modification, we will not sustain the Examiner=s rejection of
claims 1 through 3 and 10 through 15.
