Appeal No. 2006-2693 Page 2
Application No. 09/000/330
The binder resin includes a polyolefin resin having a cyclic structure, for example,
“a copolymer of an alpha olefin, such as ethylene, propylene or butylene, with an
alicyclic compound having a double bond, such as cyclohexene or norbornene.”
Page 4. A diene may be copolymerized with the polyolefin resin. Page 7.
Discussion
1. Claim construction
Claims 16, 21, 24-30, and 35 are pending and on appeal. With regard to the
obviousness rejection, the claims have been argued in four groups. See the Appeal
Brief, pages 8-16. We will focus on one claim from each group -- claims 16, 28, 29, and
30, each of which is representative of its group. Claims 21, 24, and 35 stand or fall with
claim 16. Claims 26 and 27 stand or fall with claim 29. Claims 16, 28, 29, and 30 read
as follows:
16. A toner for developing an electrostatically charged copier or printer image, the
toner consisting essentially of:
a) a binder resin;
b) a colorant which is carbon black, diazo yellow, phthalocyanine blue,
quinacridone, carmine 6B, monoazo red or perylene; and
c) a charge control agent,
wherein the binder resin includes a polyolefin resin having a cyclic structure,
wherein the polyolefin resin is a copolymer derived from an alpha-olefin, an alicyclic
compound having one double bond and, optionally, a diene monomer, and wherein the
electrostatically charged copier or printer image is fixed by the action of a heated roller.
