Application No. 08/090,343
linked density with a concomitant modification of properties
of the fully cured resin" (column 8, lines 16 et seq.), we are
satisfied that one of ordinary skill in the art would have
found it obvious to determine the optimum amount of
monoepoxide to substitute for the polyepoxide component of
Horley. Moreover, in view of the fact that the number of
epoxy groups was a known result-effective variable which
determines the cross-linked density of the cured resin, we are
convinced that it would have been obvious for one of ordinary
skill in the art to do what appellants have done, namely,
replace the preferred polyepoxide component with a certain
amount of non-preferred monoepoxide in accordance with the
target density of the cured resin.
As a final point, we note that appellants base no
argument upon objective evidence of nonobviousness, such as
unexpected results.
In conclusion, based on the foregoing, the examiner's
decision rejecting the appealed claims is affirmed.
