Appeal No. 2006-0441
Application No. 09/809,604
adhesive does not soak the porous substrate but remains on its
surface. As a result, it cannot be gainsaid that Markush fails
to describe impregnating a textile substrate with the adhesive
for purposes of Section 102, and we find no teaching or
suggestion in the reference which would have motivated one of
ordinary skill in the art to modify the viscosity of the
polyurethane composition such that it can impregnate a textile
substrate. The examiner has cited no reference which provides
the requisite evidence that one of ordinary skill in the art
would have found it obvious to modify the adhesive composition of
Markusch for impregnating textile substrates.
