Appeal No. 1997-3563 Page 4
Application No. 08/321,460
(Fed. Cir. 1984). Accordingly, we will not sustain the
examiner's rejection.
As explained by appellants (brief, page 7), the
examiner’s position appears to be "that it would have been
obvious to employ the catalyst system disclosed in the
Dammann et al. reference in the Chung adhesive composition . .
. ." See Paper No. 16, pages 5-10 for the examiner’s complete
statement of the rejection as referred to at page 3 of the
answer. However, as correctly pointed out by appellants
(brief, page 10), Dammann is directed to a catalyst used for a
coating composition and Dammann discloses using a separate
liquid or vapor phase of an amine catalyst for curing a
mixture of an isocyanate component with a hydroxyl functional
component that contains a complexed metal catalyst. See
Dammann at column 2, lines 37-40, column 3, lines 55-61,
column 4, lines 41-62 and column 10, line 50 through column
11, line 29. Consequently, Dammann together with Chung would
not suggest applying an admixture of an isocyanate component
with a catalyzed component including a hydroxyl functional
component and both an amine and complexed metal catalyst to a
bondline intermediate adherents as required by appellants’
