Appeal No. 1997-1454
Application No. 07/931,632
pursuant to 37 CFR 1.142(b) as being drawn to a non-elected
invention (see Paper No. 19) and, thus, are not before us.
The claims on appeal relate to a thin film of a
superconducting compound having the formula M CuO where "M"1-X 2-y
represents one or more alkaline earth metals, "x" is 0.05 to
0.3, and X>Y. The film is composed of alternating atomic
monolayers of CuO and "M", and the layers formed by "M" are
2-y
required to contain about 5-30% metal-atom vacancies,
consistent with the value of "x" in the aforementioned
formula.
Appellants acknowledge on page 5 of their Brief that the
claims on appeal stand or fall together. Accordingly, in
considering the issues on appeal we shall focus solely upon
illustrative claim 1 which reads as follows:
1. A thin-film of a high-temperature superconducting
compound which is formed of a predetermined sequence of
alternating atomic monolayers of CuO and M, wherein Cu has a
2-y
quadratic structural coordination, and where the layers formed
by M are specifically created with a preternatural metal-atom
vacancy of about 5-30%, and substantially more vacancies than
oxygen-atom vacancies in the CuO layers, said compound
2-y
having the formula M CuO ,
1-x 2-y
where M is one or more alkaline earth metals selected
from the group consisting of Ca, Sr, and Ba, M is the mole
1-x
ratio of total alkaline earth metals, x is 0.05 to 0.3, and
