Appeal No. 1997-3234
Application 08/040,671
Regarding claims 25 and 28, appellants acknowledge, as
discussed above, that polymeric supports having a pore volume
of 75%, based upon the total volume of the support material, were
known in the art. Also, the acknowledged prior art polymeric
supports have pore diameters in the 0.5-5 µm range and are made
of thermoplastic materials (specification, page 23, lines 28-30).
For the above reasons we conclude, based upon the
preponderance of the evidence, that the inventions recited in
appellants’ claims 1, 25 and 28 would have been obvious to one of
ordinary skill in the art within the meaning of 35 U.S.C. § 103.
DECISION
The rejection of claims 1, 3-5, 8, 13, 14, 16-22, 24-26 and
28 under 35 U.S.C. § 103 over EP ‘312 is affirmed.
