Appeal No. 2004-1062
Application No. 08/448,019
Appellant’s claimed invention is directed to a coating
composition comprising an imine of the recited formula, a
polyisocyanate, a polyaspartic ester, and an isocyanate
functional urethane. The composition is substantially free of
hydroxyl groups. According to appellant, the coating composition
of the present invention has an extended pot life, excellent
cure, and “provides coatings having impact resistance” (page 3 of
principal brief, first sentence).
Appealed claims 1-4, 7-11 and 14 stand rejected under
35 U.S.C. § 103 as being unpatentable over Aoki and Zwiener in
view of Druetzler.
Appellant submits at page 3 of the principal brief that “all
of the rejected claims should stand or fall together.”
We have thoroughly reviewed each of appellant’s arguments
for patentability. However, we are in complete agreement with
the examiner that the claimed subject matter would have been
obvious to one of ordinary skill in the art within the meaning of
§ 103 in view of the applied prior art. Accordingly, we will
sustain the examiner’s rejections for the reasons set forth in
the answer, which we incorporate herein, and we add the following
primarily for emphasis.
