THE REJECTION
Claim 4 stands rejected under 35 U.S.C. § 103 in view of
Markusch et al. as the subject matter claimed therein would
have been obvious to a person of ordinary skill in the art at
the time appellants' invention was made. We affirm.
Appellants' claim is of considerable scope. As a
"comprising" claim, the claim is not limited to the
ingredients
set forth therein but includes other disclosed but not claimed
ingredients and even other ingredients neither disclosed nor
claimed. Additionally, appellants have chosen to claim their
invention by defining the various ingredients utilized in
their process generically and in terms of the ingredients'
respective molecular weights rather than claiming specific
polyisocyanates and polyols.
