Appeal No. 2006-1903
Application No. 10/204,306
According to appellants, the invention is directed to a
titanium silicalite shaped article which exhibits a MFI, MEL or DEA
structure, where the article is formed by the process as claimed2
with only one calcination step (Brief, pages 1-3). Illustrative
independent claim 16 is reproduced below:
16. A titanium silicalite shaped article
produced by a process comprising:
a) preparing a synthesis gel containing a SiO 2
source, a TiO source, a template compound and water,2
b) crystallizing the synthesis gel under
hydrothermal conditions to obtain titanium silicalite,
c) drying the titanium silicalite from step
b)at a temperature below the decomposition
temperature of the template compound,
d) preparing a formable mass containing the product
from step c), a binder and a paste-forming agent,
e) forming a process comprising the mass from step
d)into a green shaped article,
f) optionally drying, and
g) calcining the green shaped article, wherein the
template compound is chosen in a way that the titanium
silicalite obtained by step b) exhibits MFI, MEL or DEA
structure and the calcining takes place after the
formation of the green shaped article.
The examiner has relied on Grosch et al. (Grosch), U.S. Patent
No. 6,008,389, issued Dec. 28, 1999, as the sole evidence of
unpatentability (Answer, page 3). Accordingly, claims 16 and 17
stand rejected under 35 U.S.C. § 102(a) as anticipated by Grosch
2The examiner notes that the claimed “DEA” structure should
be “BEA” (Answer, page 2, ¶(5) and ¶(7)).
