Appeal No. 1998-1178
Application 08/408,753
10. A method of manufacturing a perovskite-containing
composite material as claimed in Claim 1, by providing a
substrate with a first titanium-containing quaternary or
more complex perovskite intermediate layer, and with a
second quaternary or more complex perovskite as a covering
layer, the coating forming the intermediate layer being
sintered before the covering layer is provided.
The the following reference is applied by the examiner
in the art rejection:
Swartz et al. (Swartz) 5,198,269 Mar. 30, 1993
Claims 1-12 and 16-20 stand rejected under 35 U.S.C.
§ 102(b), as anticipated by Swartz, and under 35 U.S.C.
§ 103 as obvious over Swartz.
We refer to the brief, and to the answer, for a
complete exposition of the opposing viewpoints expressed by
the appellants and by the examiner concerning the above-
noted rejection.
OPINION
For the reasons expressed by appellants, and for the
reasons set forth below, we reverse the rejection of record.
On pages 5-6 of the brief, appellants argue that both
claims 1 and 10 require that the intermediate layer (the
layer closest to the substrate) is a titanium containing
quaternary, or more complex, perovskite. Appellants point
out that Swartz provides that the first layer (intermediate
layer) is made of lead titanate or strontium titanate, which
is a tertiary perovskite.
On page 4 of the answer, the examiner rebuts and states
that column 3, line 67 through column 4, line 5 of Swartz
suggests that where improved crystallinity is not critical,
the second layer may be deposited directly on the substrate.
The examiner concludes that when the second layer is closest
