Appeal 2007-0655
Application 10/314,157
a fuel controller connecting said fuel tank to a reservoir of
diluted fuel;
wherein the fuel controller delivers both concentrated fuel and
water into the reservoir of diluted fuel, and wherein said fuel
controller delivers the concentrated fuel to the reservoir of diluted fuel
when the fuel concentration of the diluted fuel falls below a
predetermined level.
The Examiner relies upon the following references in the rejection of
the appealed claims:
Okamoto 5,723,228 Mar. 3, 1998
Shimotori 6,572,994 B1 Jun. 3, 2003
Acker 6,821,658 B2 Nov. 23, 2004
Appellants’ claimed invention is directed to a fuel delivery system for
a liquid-type fuel cell comprising a fuel tank containing a concentrated fuel,
and a fuel controller which connects the tank to a reservoir of diluted fuel.
The fuel controller delivers concentrated fuel and water into the reservoir,
and delivers concentrated fuel to the reservoir of diluted fuel when the
concentration falls below a predetermined level.
Appealed claims 1 and 4-6 stand rejected under 35 U.S.C. § 102(e) as
being anticipated by Shimotori. Claims 1 and 7-12 stand rejected under 35
U.S.C. § 102(e) as being anticipated by Acker. Also, claim 2 stands rejected
under 35 U.S.C. § 103(a) as being unpatentable over Acker in view of
Okamoto.
We have thoroughly reviewed each Appellants’ arguments for
patentability. However, we find that the Examiner’s rejections are well-
founded and supported by the prior art evidence relied upon. Accordingly,
