Application 10/457,769
the polyolefin resin,” and introducing additional amounts of molecular
hydrogen and first olefin, wherein additional polymerization occurs during
this introducing step, that is, step c of claim 28. Claim 28 also requires that
the resulting polyolefin resin has a particular density, melt index, and long
chain branching index. We interpret claim 28 to require that additional
molecular hydrogen and first olefin be added after the polymerization is
begun.
2. REFERENCES
The Examiner relies on the following references:
Chien US 5,089,460 Feb. 18, 1992
Winslow US 5,534,472 Jul. 9, 1996
3. INDEFINITENESS
Claim 24 stands rejected under 35 U.S.C. § 112, second paragraph, for
being indefinite. Appellants do not traverse this rejection (Br. 4).
Therefore, we summarily affirm the rejection.
4. ANTICIPATION/OBVIOUSNESS
Claims 28-39, 41, and 42 stand rejected under 35 U.S.C. § 102(b) as
anticipated by, or under 35 U.S.C. § 103 as obvious over, Winslow. The
Examiner relies on Winslow, specifically Winslow’s Examples 3 and 4, for
demonstrating “a method for copolymerization of ethylene and n-hexene in
the presence of . . . supported vanadium containing catalysts which are
identical to those of the instant claims” (Answer 3-4). The Examiner argues
that, “[i]n Examples 3 and 4, hydrogen, ethylene and n-hexene are
continuously fed into a 88-gallon reactor” and that this “continuous process
meets the limitation of [claim 28] of introducing additional amounts of
