Appeal No. 2006-0587
Application No. 10/017,483
26 coupled for activation via the first threshold detector, and a
first dump load 22 “wherein the first transistor is responsive to
the stack terminal voltage across the first set of fuel cells to
selectively couple the first dump load in parallel with the first
set of fuel cells when the stacked terminal voltage across the
first set of solid polymer electrochemical fuel cells exceeds a
threshold voltage and to uncouple the first dump load when the
stack terminal voltage across the first set of solid polymer
electrochemical fuel cells is below the threshold voltage” (claim
1). This appealed subject matter is adequately represented by
claim 1, the sole independent claim on appeal, a copy of which is
set forth in Appendix A of the appellants’ brief.
The references set forth below are relied upon by the
examiner as evidence of obviousness:
Keller et al. (Keller) 3,850,695 Nov. 26, 1974
Meltser et al. (Meltser) EP 0 982 788 A2 Mar. 1, 2000
(Published European Patent Office Patent Application)
All of the appealed claims are rejected under 35 U.S.C.
§ 103(a) as being unpatentable over Keller in view of Meltser.
