Brazdil ‘588 discloses a process for manufacturing a catalyst containing vanadium,
antimony and other metal compounds. The process includes forming a catalyst precursor
having the formula VSb A O , adding a metal compound D to the surface of the catalyst
m a x
precursor and calcining the surface modified precursor to produce the catalyst. (Col. 2, ll.
26 to 48). Brazdil ‘588 also states “the catalyst precursor can be prepared by any method
known in the art for synthesis of mixed metal oxides.” (Col. 2, ll. 49 to 50). Brazdil ‘588
discloses the metal compound D is added to the catalyst precursor any time after the
precursor has been formed. (Col. 2, ll. 58 to 60).
Brazdil ‘016 discloses a process for manufacturing a catalyst containing vanadium,
antimony and other metal compounds. The process includes forming “an aqueous slurry of
a mixture of source batch materials comprising compounds of said elements to be included
in the final catalyst.” (Col. 2, ll. 38 to 41). The mixture of batch materials is calcined to
form an activated catalyst. (Col. 2, ll. 41 to 50).
The Examiner asserts Brazdil ‘588 discloses an unsupported or supported mixed
metal oxide catalyst, wherein the catalyst can be prepared by any method known in the art
for synthesis of mixed metal oxides. (Answer, p. 3, ll. 14 to 16). The Examiner also
asserts
