Appeal No. 96-1720
Application 08/389,520
319, 321, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989); In re Sneed,
710 F.2d 1544, 1548, 218 USPQ 385, 388 (Fed. Cir. 1983); In re
Okuzawa, 537 F.2d 545, 548, 190 USPQ 464, 466 (CCPA 1976).
Appellants’ specification states (page 19, lines 9-15):
It is highly preferred that the acid which is
used in the surfactant be an acid which is capable
of catalyzing the crosslinking of the polymer and
the aminoplasts. Such acids are described above and
include the various sulfonic acids described in the
preceding paragraph. After the dispersion is
applied to the substrate, usually after being
formulated for a specific application such as a
coating, adhesive or sealant, the volatile amine in
the surfactant will evaporate into the atmosphere,
freeing the acid to catalyze the curing reaction
between the amino resin and the epoxidized polymer.
This portion of appellants’ specification indicates that the
term “crosslinked” in “crosslinked coating”, “crosslinked
adhesive” and “crosslinked sealant” means that a curing
reaction has taken place between the aminoplast and the
epoxidized polymer.
However, the dispersion recited in each of appellants’
independent claims contains 10-65 wt% polydiene block polymer
and 0.1-10 wt% aminoplast. These are the percentages of these
components which appellants’ specification states are present
in the dispersion of crosslinkable polymer, i.e., polymer
