component which is a bisphenol, biphenol, thiodiphenol and the
like (column 5, line 66 – column 9, line 41). However, the
claimed two-component system does not exclude this component, as
it reasonably appears that it functions within the context of the
claimed two-component system (it has at least two reactive OH
groups, although not a polyol).
A two component system can have different types of
ingredients in it, yet still fulfill the principal definition of a
two component system having one component (which can be a mixture
of ingredients) with two OH groups, and another component (which
may be a mixture of ingredients) containing the reactive
isocyanate groups. The appellants have provided no evidence
otherwise that the reaction is materially affected, nor have they
restricted their claim to exclude this ingredient. We therefore
find that the inclusion of the third phenolic ingredient of
Furness is within the claim scope and conclude that it is not
fatal to the case of obviousness.
We find that Furness further suggests suitable solvents for
the phenolic and resinous components, which include a wide variety
listed from lines 41-61 of column 9. The resinous component is
mixed to homogeneity (column 9, lines 61-63).
We find that Furness also discloses organic polyisocyanates
and suitable solvents, at column 10, lines 35-41. These solvents
