Application No. 08/463,883
perovskite ceramic, the sol being susceptible to heating by
absorbing microwave energy, and exposing the coated substrate
to microwave radiation to sinter the sol to a perovskite
ceramic by heating. Further details of this appealed subject
matter are set forth in the appealed claim which reads as
follows:
23. A sintering process for preparing a perovskite
ceramic, comprising the steps of:
(a) coating a substrate with a sol containing precursors
of the perovskite ceramic, the sol being susceptible to
heating by absorbing microwave radiation;
(b) exposing the coated substrate to microwave radiation
for pulses of selected duration to sinter the sol to a
perovskite ceramic by heating the coated substrate to a
temperature above 800 F.B
No references have been relied upon by the examiner in
the rejection before us on this appeal.
Claim 23 stands rejected under the first paragraph of 35
U.S.C. § 112. It is the examiner’s basic position that claim
23 does not comply with either the written description
requirement or the enablement requirement of this paragraph
because the claim is directed to a perovskite ceramic
generically rather than to a LaMnO -family perovskite ceramic

specifically. According to the examiner, “[t]he
