Application No. 10/346,099
‘polyisocyanate’ includes both monomeric isocyanates and polymeric isocyanates that
contain more than one isocyanate functional group.” Page 7. Thus, we interpret a
“polyisocyanate” to have two or more isocyanate groups.
2. Anticipation
The examiner has rejected claims 9-11, 13-18, 21-26, 28, and 31-38 under
35 U.S.C. § 102(b) as anticipated by Holubka.1 Holubka describes oligomers
comprising the reaction product of a polyol with a half-blocked diisocyanate. Col. 3,
lines 35-37.
With regard to claim 21, the examiner argues that Holubka discloses “a process
of making a thermoset comprising the steps of: (a) providing a glycidyl ether and an
alcohol (column 3, lines 64 through column 4, line 20); wherein the glycidyl ether
contains more than one epoxide groups (column 4, lines 21-62); (b) reacting the glycidyl
ether with the alcohol to make a polyol monomer (column 5, lines 43-60); and
(c) reacting the polyol monomer with polyisocyanate (column 6, line 61 through
column 7, line 27).” Examiner’s Answer, page 4. With regard to claim 31, the examiner
argues that Holubka discloses “a process of making a thermoset comprising the steps
of: (a) providing a polyol monomer comprising [the formula of claim 31] (column 4,
line 19 through column 5, line 60) . . .; and (b) reacting the polyol monomer with a
polyisocyanate (column 6, line 61 through column 7, line 27).” Examiner’s Answer,
page 5. The examiner argues that “[a] half-blocked diisocyanate is still considered a
diisocyanate.” Examiner’s Answer, page 12.
