Appeal No. 95-4203
Application 07/793,889
1. A photosensitive cationically polymerizable epoxy based imaging system
comprising:
an epoxy based resin system having solids comprising between about 10%
and about 90% by weight of a polyol resin having a molecular weight between 60,000 to
about 130,000;
between about 10% and about 90% by weight of a brominated epoxy resin
of a low molecular weight;
from about 0.1 to about 15 parts by weight of a cationic photoinitiator
capable of initiating polymerization in said epoxidized resin system upon exposure to
actinic radiation;
said resin system being further characterized by having an absorbance of
light in the 330 to 700 nm region of less than 0.1 for a 2 mil thick film.

I.
Claims 1-24 stand rejected under 35 U.S.C. § 112, first paragraph, for lack
of description of the claimed molecular weight range of 60,000 - 130,000.
The specification discloses molecular weight ranges of 40,000 -130,000 and 60,000-
90,000. The examiner concedes that the claimed range is within the disclosed ranges in
the instant specification, however he contents that the range of 60,000-130,000 is not.
We reverse this rejection. 35 U.S.C. § 112 does not require that the
invention claimed be described in ipsis verbis in order to satisfy the description
