Application No. 08/155,881
inserting the molding material into a container,
the container attached to the designated mold to
allow the molding material to pass from the
container into the mold when a force is applied
to the molding material;
applying a gradient heat to the molding material
in the container to make the molding material
more malleable, the gradient heat having a
temperature distribution from a least heat to a
greatest heat, wherein the greatest heat is
applied to molding material closest to the mold
and the least heat is applied to molding
material furthest away from the mold; and
forcing the molding material from the container
into the mold while allowing air to escape along
sides of the container and out a container
opening furthest away from the mold.
The examiner relies upon the following reference as
evidence of obviousness:

Appellants' claimed invention is directed to a method of
applying a molding material into a mold. The method entails
inter alia "applying a gradient heat to the molding material
. . . the gradient heat having a temperature distribution
from a least heat to a greatest heat" (claim 1) with the
greatest heat being applied to the material that is closest to
the mold. According to appellants, in the claimed process
