Appeal No. 2003-1893
Application No. 09/770,018
& Research Found. v. Genentech Inc., 927 F.2d 1565, 1576-77,
18 USPQ2d 1001, 1010 (Fed. Cir. 1991).
The appellants do not dispute the examiner’s finding that
Marvil discloses forming “a fuser member having a fluoropolymer
coating on a compliant silicon rubber base layer bonded to a
metallic insert . . . .” Compare the Answer, page 3, with the
Brief, page 5 and the Reply Brief, page 1. We find that Marvil
teaches that its fluoropolymer coating is made from the same
fluoropolymer embraced by claim 1 on appeal. Compare Marvil,
column 1, lines 32-35 and column 5, lines 10-60, with the
appellants’ Specification, page 7. Specifically, we find that
Marvil teaches using fluoroelastomers, such as poly(propylene-
tetrafluoroethylene) (PTFE), disclosed at page 7 of the
appellants’ Specification. See Marvil, column 1, lines 32-35 and
column 5, lines 10-60. We, like the examiner, find that Marvil
also teaches subjecting an outer fluoropolymer coating in an
infrared oven for a selected period after it is sprayed on the
primed pre-baked silicone rubber layer. Compare column 4, lines
1-22 with claim 1 on appeal and the appellants’ Specification,
page 8.
Although Marvil does not mention that its cured
fluoropolymer is “cross-linked”, see, e.g., column 4, lines 20-21
