Appeal No. 1999-0984 7
Application No. 08/696,248
polyurethane, based upon a teaching of a rubber elastomer. In particular the suggestion of
Beucker to calendar and stretch the elastomer material in one direction in sheet form,
column 1, lines 52-57, does not provide the requisite motivation to utilize the disclosed
Beucker’s stretching technique, for a two component urethane resin. Moreover, on the
record before us, we find no suggestion of introducing the fibers into the polyurethane as
the urethane leaves the dispenser head, as required by the method claims.
Finally, WO ‘16820 is directed to a method of making a shoe press belt by applying
a polymer coating to the base cloth wherein the polymer coating is impregnated with an
aramid, Kevlar, thixotrope. See Abstract, pages 1 and 2. However, WO ‘16820
specifically discloses that the fibers present are aligned in the direction of the applied shear,
page 2, as opposed to a transverse direction. Accordingly, the disclosure of WO ‘16820
fails to overcome the deficiencies of the other references.
DECISION
The rejection of claims 1 through 6 under 35 U.S.C. §103(a) as being
unpatentable over Adams in view of McCarten, and/or Beucker and/or WO’16820 is
reversed.
