Appeal No. 2006-2677 Page 2
Application No. 10/346,099
where R1 is aliphatic or aromatic and R2 is aliphatic, aromatic, ester, ether, or acrylic.
In addition, R1 contains a hydroxyl group and/or R2 contains -O-CH2-CH(OH)-. Page 2.
The specification states that the R1-O- group can be described as a residue of an
alcohol. Page 5.
In addition, the specification describes a process of making a thermoset by
reacting an epoxy with an alcohol to make a polyol monomer, wherein the epoxy
contains more than one epoxide group and/or the alcohol is a polyol, and reacting the
polyol monomer with a polyisocyanate. Page 2. The specification states that the epoxy
may be a glycidyl ether. Page 5.
Discussion
1. Claim construction
Claims 9-11 and 13-41 are pending and on appeal. We will focus on claims 9,
21, and 31, which read as follows:
9. A thermoset formed by reacting a polyisocyanate with a polyol
monomer;
wherein the polyol monomer comprises the formula:
wherein R1-O- is a residue of an alcohol selected from the group
consisting of methanol, ethanol, propanol, butanol, 1,2-ethane-diol,
isopropanol, 1,2-propane-diol, 1,3-propane-diol, 1,3-cyclohexane-diol, a
glycol, and a C15 alcohol;
wherein R2 is selected from the group consisting of aliphatic, aromatic,
ester, ether, and acrylic group; and
