Appeal No. 97-0268
Application No. 07/991,872
The subject matter on appeal relates to a dehydrogenation
catalyst which comprises an intermediate pore size zeolite
having a silica to alumina mole ratio of a least 30 and less
than 500. Further details of this appealed subject matter are
set forth in representative independent claim 32 which reads
as follows:
32. A dehydrogenation catalyst which comprises:
(a) platinum or palladium;
(b) an intermediate pore size zeolite having a silica to
alumina mole ratio of at least 30 and less than 500 and
crystallite size less than 10 microns; and
(c) an alkali content wherein the alkali to
aluminum ratio in the zeolite is between about 1 and
about 5 on a molar basis.
The reference relied upon by the examiner as
evidence of obviousness is:
Miller et al. (Miller) 5,169,813 Dec. 8, 1992
All the claims on appeal are rejected under 35
U.S.C.
§ 103 as being unpatentable over Miller.2
2The appealed, claims will stand or fall together: see
page 3 of the brief and 37 CFR 1.192(c)(7)(1995).
Accordingly, we will focus upon claim 32, the sole independent
claim before us, in assessing the merits of the examiner's
rejection.
