Appeal No. 2001-0857 Page 3
Application No. 09/012,166
states that the claims do not specify how the components are
combined, in what order they are combined, when they are
combined, and how much of each component is used, or whether
or not the components react with each other. The examiner
states that independent claims 13 and 14 only recite that
these components are mixed.
On page 3 of the answer, the examiner’s basic position
is that Liebl discloses coatings comprising polyisocyanates,
polyols, oxazolidine, and toluene sulfonic acid. The
examiner states that Liebl differs from appellants’ claims
by not listing polyiscocyanurates, and by not adding
mercapto propyl trimethoxy silane to the coating
composition.
The examiner relies upon De Santis for teaching to add
mercapto propyl trimethoxy silane to polyurethane primers,
and for including polyisocyanurate in the primer. (answer,
page 3).
The examiner states that it would have been obvious to
one of ordinary skill in the art to have included
mercapto propyl trimethoxy silane in the coating of Liebl in
view of De Santis, and to include polyiscyanurate in view of
De Santis. (answer, pages 3-4, Paper No. 18 pages 2-3).
On page 6 of the brief, appellants point out that Liebl
concerns elastic floor coverings and inner surfaces of molds
and refers to column 1, lines 7 through 11.
On page 7 of the brief, appellants point out that De
Santis relates to the construction of glass wall buildings
and to the mounting of windshields, rear windows, and
taillights. Appellants also state that De Santis relates to
primer/sealant systems useful as sealing, caulking, and
patching compositions, and as adhesives.
