Appeal No. 93-1311
Application 07/279,713
many of the layer thicknesses disclosed by Jones, and the largest
sphere diameter disclosed by Beck is larger than any of the layer
thicknesses disclosed by Jones. It is apparent that the spheres
of Beck could not possibly be used as a burn-out material in the
coating of Jones to the extent that sphere diameter is greater
than coating layer thickness. Moreover, for all we know based on
the record before us, Beck’s method of forming hollow inorganic
spheres is incapable of producing spheres of a sufficiently small
diameter as to be effectively used in Jones’ coating layer.
Under the circumstances recounted above, we cannot agree
with the examiner’s conclusion that it would have been obvious
for one with ordinary skill in the art to use the spheres of Beck
in the coatings of Jones. It follows that we cannot sustain the
above noted section 103 rejection of claims 1 through 37 as being
unpatentable over Jones in view of Beck.
