Appeal No. 95-4216
Application 08/035,076
suspension recited in appellants’ claims and the
oxychlorination catalyst component in those claims are
separate and distinct components of the composition. In
addition, because appellants’ solution and suspension are used
alternatively, the teaching that powdered copper, a powdered
copper compound or fresh catalyst containing copper can be
added in addition to the solution indicates that appellants’
recited suspension, like the solution, is separate and
distinct from these powders or catalyst particles.
Thus, appellants’ claims, when given their broadest
reasonable interpretation consistent with the specification,
do not include compositions in which the catalytically active
or reactive copper compound is suspended in a gas but, rather,
are limited to compositions in which the catalytically active
or reactive copper compound is suspended in a liquid.
The Cowfer reference
Cowfer discloses a process for inhibiting the stickiness,
in fluidized beds, of an oxychlorination catalyst for ethylene
composed of cupric chloride on fluidizable alumina support
particles (col. 2, lines 61-65). This inhibition of
stickiness is accomplished by adding bare support particles to
-5-5
