Appeal No. 1998-3187
Application No. 08/130,517
appellants, Hager discloses an isocyanate index of between 0.90
and 1.20 as opposed to commercial values of 1.0 to 1.15.2
Consequently, it can be seen that Hager provides no guidance for
obtaining a flexible polyurethane foam having the claimed IFD by
using a polymeric MDI having the claimed isocyanate index of
about 0.80. Appealed claims 29, 30 and 31 define polyurethane
foams in accordance with claims 19, 20 and 21, respectively. We
will not reverse the examiner's rejection of claim 32 since it
recites an IFD of about 24 lbs. which is clearly taught by Hager.
In conclusion, based on the foregoing, the examiner's
rejection of claims 25-28 and 32 is affirmed. The examiner's
rejection of claims 19-21 and 29-31 is reversed. Accordingly,
the examiner's decision rejecting the appealed claims is
affirmed-in-part.
2 The examiner has not challenged appellants' statement that
the claimed 0.80 corresponds to 80 in Hager's terminology.
