article continued to search for desirable metals that were
compatible with high temperature superconductors. This
paragraph as well as the remaining portions of Lichtenberg’s
article indicates that the art desired to minimize lattice
mismatches between layered materials to increase overall
conductivity. The same may be said of the resistivity
measurements in various planes of orientation.
This first paragraph of Lichtenberg at column 1 on page
1138 also indicates that SrTiO was considered in the art to
3
be a standard insulating substrate for the growth of
superconducting copper oxide films, which is the same basic
substrate utilized by appellants in their disclosed, but
unclaimed invention. The paragraph in the middle of the
second column at page 1139 of Lichtenberg also indicates that
certain epitaxial relationships existed between well known
superconductor materials and their substrates. This paragraph
also indicates that the Sr RuO , utilized primarily in
2 4
Lichtenberg as a substrate for the growth of superconducting
materials, has an in-plane alignment of the perovskite axes of
the film and the substrate. Since this Sr RuO is stated to
2 4
have perovskite axes, this alone would have suggested to the
