Application No. 08/430,083
21 USPQ2d 1941, 1943-44 (Fed. Cir. 1992); In re Fine, 837 F.2d
1071, 1074, 5 USPQ2d 1596, 1598-99 (Fed. Cir. 1988).
Here, the examiner makes reference to Example 1 of
Mosbach (answer, page 3) where Mosbach discloses the use of a
mixture of a uretdione diisocyanate (dimer) and an
icocyanurate polyisocyanate (trimer) as part of a
polyisocyanate mixture having an NCO content of 21.6 percent
which is mixed with dimethoyl propionic acid and N-methyl
morpholine until the NCO content of the mixture is reduced to
15.3 percent. The mixture is subsequently cooled, a solution
thereof is applied to a glass plate and then dried to form a
film thereon. The examiner additionally makes reference to
column 5, line 31 of Mosbach wherein a portion of a sentence
of the patent describes uretdione groups or carboxl groups
present in the polyisocyanates mixtures of the patent as
available reactive centers in forming high molecular weight
polyurethanes. The examiner also notes column 7, line 34 of
Mosbach wherein a hardness value is reported for an oven dried
film of a polyisocyanate mixture made from the starting
components of the polyisocyanate mixture of Example 1 together
