carbon atoms, an araliphatic hydrocarbon group
containing from 8 to 15 carbon atoms, or an
aromatic hydrocarbon group containing from 6 to
about 15 carbon atoms,
b) an isocyanate reactive component comprising one or
more high molecular weight polyether polyols
having from 2 to 6 hydroxyl groups and a number
average molecular weight of at least 250 to 8,000
and 0 to 10% by weight of a low molecular weight
diol or triol having an equivalent weight of 31 to
99, and
c) an organometallic catalyst,
wherein the isocyanate reactive component b) contains no
more than 0.1% by weight water prior to reaction with the
liquid polyisocyanate a).
The examiner relies upon the following reference in the
rejection of the appealed claims:
Markusch et al. (Markusch) 6,187,892 Feb. 13, 2001

composite comprising the recited polyurethane composition
impregnated in a geotextile.
Appealed claims 2, 5-11 and 21 stand rejected under 35
U.S.C. § 102(e) as being anticipated by Markusch. Claims 12-14,
19-22 and 25-32 stand rejected under 35 U.S.C. § 103(a) as being
