Appeal No. 95-4984
Application No. 08/038,369
appellants' own specification acknowledges that the claimed
relationship was known in the art at the time of filing the
present application. To wit, the specification states
"[c]urrent methods of effectively applying such high-cure-
temperature coatings to a thermally-massive part require that
the part to be coated be heated in excess of temperatures at
which the aluminum alloy begins to lose tensile/yield
strength"
(page 3, lines 5-9), and "[a]s mentioned above, the heat
treated aluminum alloy has a known temperature-time envelope
above which point the particular alloy begins to lose its
tensile/yield strength. This temperature-time envelope is
defined by a curve unique to each aluminum alloy" (page 10,
lines 4-8).
Accordingly, based upon the unrebutted, reasonable
finding of the examiner, and the apparent admission by
appellants in the present specification, we find that the
examiner has drawn the proper legal conclusion that one of
ordinary skill in the art would have found it obvious to rely
upon known result-effective variables in order to
experimentally determine the optimum, as well as acceptable,
