Application No. 10/734,979
of Formula I in the process described by Sadvary. Appellants did not identify any
deficiency in the Examiner’s reasoning that the remaining steps in the claim would have
been obvious and we find no error in that conclusion.
The Examiner cites Sadvary for its teaching of curing agents to crosslink
polysiloxane monomers. Of the six specific curing agents identified in the Sadvary
application (“aminoplasts, polyisoc[y]anates, triazines, polyepoxides, polyacids, and
polyols”), Sadvary incorporates by reference the Jacobs patent for its disclosure of
tricarbamoyl triazine compounds which correspond to the class which is recited in claim
1 of this appeal. Sadvary, ¶¶ 41 and 48. These compounds are derived from
triisocyanato triazines by the modification of the isocyanate (-NCO) with a blocking
group, X-R, in which X is preferably oxygen or carbon. Jacobs, column 2, line 45-
column 3, line 12.
In his examples, Jacobs discloses species of the Formula I genus recited in claim
1. Example 4 shows a triphenyl (C6) carbamoyl (column 9, lines 30-40); Example 5 is of
a triethylhexyl (C8) carbamoyl (column 9, lines 50-60). These are reproduced below:
