We find that in Snowden, core layer 70 has high conductivity
as well as high thermal conductivity (col.4, lines 15-20). As
shown in figure 5, superconducting layer 68 is formed of layers
80 of superconducting material, interspaced with layers 82 which
"may be a material of normal conductive or insulative properties"
(col. 4, lines 60-67). Although the innermost layer 82 of
superconducting layer 66 abuts core layer 70, layer 82 is formed
on the outside of layer 70 and is not formed as an electrically
insulating material on an outer stratum of elongated wire-like
layer 70, as required by claim 1. In addition, we find that
Sakurai2 is directed to a fiber optic cable that is comprised of
an optical fiber 1 surrounded by a conductive layer 7, which in
turn is encased in plastic jacket 8 (figure 2 and translation,
page 2). From the disclosure of Snowden relating to a
superconductive wire, and the teaching of Sakurai relating to a
nonsuperconducting cable, we find no teaching or suggestion that
would have motivated an artisan to combine the teachings of the
two references in order to provide Snowden with a light
conducting inner layer or core, as advanced by the examiner. In
addition, because Snowden teaches that the inner core be a
2 We rely upon the translation provided by the PTO. A copy of the
translation accompanies the decision.
