Appeal 2007-1018
Application 10/376,782
member, woven mesh, non-woven mesh, wadded fibers and foamed metal,
the substrate defining a plurality of structural features selected from the
group consisting of apertures, pores and channels and dimensioned and
configured to permit the flows of fluid through the substrate, thereby
defining fluid flow paths through the substrate, the catalyzed substrate
having an electric arc sprayed metal anchor layer located on the substrate
surface of the fluid flow paths and a catalytic material located on the anchor
layer, the catalytic material comprising a bulk refractory metal oxide having
dispersed thereon one or more catalytically active metal components and the
anchor layer comprises nickel and aluminum; and
a canister having an inlet opening and an outlet opening and within
which the catalyzed substrate is enclosed, the analyzed substrate being
disposed between the inlet and outlet openings, whereby at least some of a
fluid flowing through the canister between the inlet and outlet openings
thereof is constrained to follow the fluid flow paths and thereby contact the
catalytic material disposed on the anchor layer.
The Examiner relies upon the following references as evidence of
obviousness:
Rondeau US 4,027,367 Jun. 7, 1977
Ishida US 4,455,281 Jun. 19, 1984
Fukui US 5,569,455 Oct. 29, 1996
Appellants' claimed invention is directed to an exhaust treatment
apparatus having a catalyzed substrate. An electric arc sprayed metal layer
is coated on the substrate before the catalytic material is deposited thereon.
The anchor layer comprises nickel and aluminum.
Appealed claims 27-29, 31, 32, 35, and 36 stand rejected under
35 U.S.C. § 103(a) as being unpatentable over Ishida in view of Rondeau.
Claims 33, 34, and 37 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over the stated combination of references further in view of
Fukui.
