Appeal No. 1997-3906
Application No. 08/233,482
obviousness conclusion. Certainly, Edwards contains no
disclosure which would have suggested replacing his
polypropylene based composition with a composition comprising
a polyethylene component having the melt index and molecular
weight distribution required by the independent claims on
appeal. As previously indicated, the only polyethylene
component disclosed by Edwards is unquestionably different
from the appellants’ claimed polyethylene component. Further,
the examiner points to nothing specific and we find nothing
independently in the Canadian patent or Uno which would have
suggested modifying Edwards’ process so as to result in use of
a composition comprising the polyethylene component under
consideration for extrusion coating at a temperature in the
range of 175E up to 290EC as required by the appealed claims.
Under the foregoing circumstances, we cannot sustain the
examiner’s section 103 rejection of the appealed claims as
being unpatentable over Edwards alone or taken with the
Canadian patent and Uno.
