and, more particularly, a suggestion for the claimed moisture
permeability
of from about 25 perms to about 50 perms. Therefore, the
rejections based upon Bodrogi must be reversed.
The Silverstein patent addresses decorative composite
materials or laminates for use in wall coverings.
Specifically, the patentee relies upon a polymeric plasticized
polyvinyl chloride film applied to, for example, a nonwoven
substrate. The object of Silverstein is to effect a wall
covering with greater stain resistance, washability and
wearability. As was the case with the Bodrogi reference,
supra, we do not discern from the overall Silverstein teaching
any suggestion for the claimed moisture permeability of from
about 25 perms to about 50 perms or for a nonwoven substrate
having an array of hydroentangled fibers. It follows,
therefore, that the rejections based upon this reference must
be reversed.
Like the examiner, we fully appreciate the relevance of
the Rusincovitch patent to the claimed subject matter. The
patentee teaches a porous, breathable wall covering to
