Appeal No. 96-2105
Application 08/059,861
THE REJECTION
Claims 1-17 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Brunsvold in view of Ito.
OPINION
We have carefully considered all of the arguments
advanced by appellants and the examiner and agree with
appellants that the aforementioned rejection is not well
founded. Accordingly, we do not sustain this rejection.
We need only to address appellants’ broadest claim, which
is claim 1.
The portion of Brunsvold relied upon by the examiner is
example 2A (col. 6, lines 16-48), in which poly(styrene-co-N-
(4-t-butyloxycarbonyloxyphenyl)-maleimide is prepared from a
reaction mixture of poly(styrene-co-N-(4-hydroxy-phenyl)-
maleimide, 4-dimethylaminopyridine, di-t-butylpyrocarbonate,
and triethylamine. The amounts of 4-dimethylaminopyridine and
triethylamine used in this example are not disclosed.
