Application No. 08/677,062
According to appellants, the invention is directed to
multiphase catalyst compositions consisting essentially of
chromium fluoride and a crystalline fluoride of one or more
specific metals where the atom percent of chromium is at least
equal to the atom percent of the crystalline metal fluoride
and the phases of the crystalline fluorides are homogeneously
dispersed with phases of chromium fluoride (Brief, page 2). A
copy of illustrative claim 3 is attached as an Appendix to
this decision.
The examiner has relied upon the following reference in
support of the rejections:
Fiske et al. (Fiske) 4,147,733 Apr. 3, 1979
Appellants rely upon the following reference in rebuttal
of the examiner’s rejections:
Schwarz et al. (Schwarz), “Methods for Preparation of
Catalytic Materials,” 95 Chem. Rev., no. 3, 477-510 (American
Chemical Society, 1995).
Claims 2-3 and 10-11 stand rejected under 35 U.S.C. §
102(e) as anticipated by or, in the alternative, under 35
U.S.C. § 103(a) as unpatentable over Fiske (Answer, page 3). 1
