Application No. 10/345,711
polyisocyanate are sprayed, scattered, spread-coated or rolled
onto the particulates.
Claim 28
Claim 28 further limits claim 20 by reciting that “the mold
is a pressure tight mold” (intervening claim 22), “the forming
and reacting are carried out at a temperature of from 10ºC to
30ºC” (intervening claim 25), and “the pressure is from 50 Kg/cm2
to 100 Kg/cm2” (claim 28).
As noted above, Markusch teaches that the processing
temperature is preferably between 5ºC and 150ºC and that the
materials may be molded under pressure at temperatures from room
temperature up to about 200ºC. (Column 14, lines 53-64.) Given
these teachings, it is our judgment that one of ordinary skill
in the art would have found the requisite motivation,
suggestion, or teaching to arrive at optimum or workable ranges
of pressures and temperatures. In re Peterson, 315 F.3d 1325,

of scientists or artisans to improve upon what is generally
