Appeal No. 2001-0771
Application No. 09/103,528
pursuant to the provisions of 37 CFR § 1.142(b), as being drawn
to a nonelected invention and, thus, are not before us.
The claims before us are directed to an EU-1 zeolite
(hereinafter referred to as EU-1), defined in “product-by-
process” terms, as well as a process for modifying EU-1 by
removing at least some of element “T,” e.g., aluminum, from a
starting zeolite.
Appellants request separate consideration of claims 3-6.
Therefore, all the other claims on appeal stand or fall with
claim 1, the sole independent claim. Accordingly, we focus our
attention primarily upon claim 1 which reads as follows:
1. A modified EU-1 zeolite comprising silicon and an
element T which is Al, Fe, Ga, or B, produced by a process
in which at least a portion of elements T are removed from a
starting zeolite, whereby the modified zeolite has a global
atomic ratio Si/T higher than that of the starting zeolite,
by at least 10% of the Si/T ratio of the starting zeolite.

appeal are:
