Appeal No. 2003-1893
Application No. 09/770,018
outer fluoropolymer coating. See column 4, lines 21-22 and 45-
48. As pointed out by the examiner (the Answer, page 4) and not
disputed by the appellants (the Brief and the Reply Brief in
their entirety), “cure is well known in the art to mean
crosslinking of a polymer. . . .” Indeed, the Polymer Science
Dictionary referred to by the examiner defines the term “cure” as
follows (page 97):
Cure (1) The process of deliberately crosslinking a
polymer to improve its properties, especially the
mechanical properties such as stiffness . . . .
Thus, we concur with the examiner that Marvil, as explained by
the Polymer Science Dictionary, fully describes the claimed
subject matter within the meaning of 35 U.S.C. § 102.
The appellants argue that the fluoropolymer described in
Marvil is not “cross-linked”. See the Brief and the Reply Brief
in their entirety. However, the appellants have not proffered
any evidence to support this argument. See In re De Blauwe,
736 F.2d 699, 705, 222 USPQ 191, 196 (Fed. Cir. 1994);
In re Lindner, 457 F.2d 506, 508, 173 USPQ 356, 358 (CCPA 1972).
As such, we are not persuaded by this argument.
