Appeal 2007-0217
Application 10/711,278
The Examiner relies upon the following references in the rejection of
the appealed claims:
Herman US 3,884,871 May 20, 1975
Uytterhoeven US 4,663,265 May 5, 1987
Sakai US 5,750,258 May 12, 1998
Devonport US 6,103,380 A Aug. 15, 2000
Matyjasjewski US 6,121,371 A Sep. 19, 2000
Katoh US 6,514,328 B1 Feb. 4, 2003
Appellants’ claimed invention is directed to a process for producing a
polymer-coated pigment particle and dispersing the particle into a
suspending fluid to form an electrophoretic medium. Appealed claim 35 is
limited to a titanium particle but does not include the step of dispersing the
polymer-coated pigment particle into the suspending fluid. The particle is
reacted with a reagent which has a functional group that reactively bonds to
the particle as well as a polymerizable or polymerization-initiating group.
The particle/reagent product is reacted with a monomer or oligomer which
results in the formation of a polymer bonded to the particle.
The appealed claims stand rejected under 35 U.S.C. § 103(a) as
follows:
(a) claims 1, 8-11, 14 and 15 over Devonport or Sakai in view of
Uytterhoeven,
(b) claims 1, 8, 11-13, 19 and 20 over Devonport over Uytterhoeven,
(c) claims 13 and 15-18 over Devonport in view of Uytterhoeven and
Matyjasjewski, and
(d) claims 35-42 over Katoh in view of Sakai.
Also, claims 35, 36, 39, and 40 stand rejected under 35 U.S.C. § 102(b) as
being anticipated by Herman.
