Appeal No. 1997-3243
Application 08/290,093
consider the claim to require that the pressure sensitive
adhesive is applied to the paper prior to the paper being
wound into a roll.
Parrotta discloses an adhesive product which includes a
substrate, an intermediate layer of a normally tacky pressure
sensitive adhesive, and a top layer of microspheres (col. 2,
lines 25-34). The microspheres cover the adhesive layer such
that the surface has substantially no tack when the
microsphere layer remains intact, but is tacky when sufficient
pressure is applied to the product to cause the microspheres
to be displaced into the adhesive layer, thereby exposing the
adhesive layer (col. 2, lines 34-37; col. 4, lines 3-16).
The examiner argues that Parrotta discloses at column 1,
lines 7-11, column 2, lines 17-21, column 5, lines 4-33, and
figure 2, a product like appellant’s claimed product except
for the predetermined web tension and the specific genus of
adhesives (answer, page 3). We do not find in the portions of
the reference relied upon by the examiner any indication that
the adhesive is applied to the substrate prior to the
substrate being wound into a roll as required by appellant’s
