Appeal No. 95-2734
Application 07/952,060
DECISION ON APPEAL
2
This is a decision on an appeal from the final rejection of claims 1 through 20
which are all of the claims in the application.
The subject matter on appeal relates to a catalyst for promoting oxidization-
reduction reactions with the exhaust gas of an internal combustion engine, to a
corresponding process for so treating such exhaust gas and to a process for making
the aforementioned catalyst. This subject matter is adequately illustrated by
independent claims 1, 6, and 18, which read as follows:
1. A catalyst for promoting oxidation-reduction reactions with the exhaust gases
produced by an internal combustion engine comprising:
tungsten oxide;
a basic metal oxide having a Ph [sic, pH ] greater than that of tungsten oxide;pzc pzc
and
a noble metal wherein at least 51 weight percent of the total weight of the basic
metal oxide is present as a separate layer in juxtaposed relation to the tungsten oxide.
6. A catalyst for promoting oxidation-reduction reactions with the exhaust gases
produced by an internal combustion engine comprising:
a composite oxide comprised of:
a refractory inorganic oxide;
2In claim 1, the capitalization of pH is in error and should be corrected in any
further prosecution that may occur.
