Appeal No. 2001-2396
Application 09/286,150
OPINION
We reverse the aforementioned rejection. We need to address
only the independent claims, i.e., claims 1, 11 and 16.
Claims 1 and 16
Kellner discloses a method for the catalytic hydrogenolysis
of at least one 3-4 carbon acyclic saturated halofluorocarbon or
hydrohalofluorocarbon, wherein all non-fluorine halogen
substituents are on end carbons, at a temperature of about 300ºC
or less, using a catalyst comprising, on a low-ash carbon
support, palladium and optionally additional group VIII metals
such as Pt, Ru, Rh or Ni (col. 1, line 58 - col. 2, line 15).1
Kellner states that his method provides high selectivity to
products having the same number and relative position of fluorine
substituents as the starting material (col. 2, line 66 - col. 3,
line 2). Kellner’s method differs from those in the appellants’
claims 1 and 16 in that Kellner’s non-fluorine halogens are on
end carbons whereas the appellants’ chlorine atoms are on the
middle carbon, and Kellner’s desired product has the same number
