based alloys or nickel based alloys or superalloys,
said ductile metallic phase extending throughout the
body of said ceramic matrix, said ductile metallic
phase of said composite comprising a continuous,
interconnected, ordered, repeating ductile metallic
array forming a repeating pattern structure, said
ductile metallic array having thickness of 0.003 inches
or less and which is embedded within, surrounded by,
supporting and in intimate contact with said ceramic
body substantially throughout the composite body so as
to provide a high degree of interface between the
ceramic and metallic array resulting in a ceramic
composite which is non-brittle in practical use and
which has a thickness of 0.01 inches or less.
The examiner relies upon the following references as
evidence of obviousness:

Appellant’s claimed invention is directed to a solid
electrolyte composite comprising an ionically conductive ceramic
matrix and a ductile metallic phase extending throughout the
matrix. According to appellant,
[t]he importance of the resulting composite electrolyte
is that it is ductile in the sense that it is
sufficiently strong to withstand stresses to which it
