Appeal No. 1996-2357
Application 08/124,617
containing any of these species. We therefore reverse on the
merits the rejection of claims 4, 7 and 8 over Bögemann, alone
or with Fujii.
Rejections over Boustany or Kleiman,
each alone or in view of Fujii
We need only to address claim 3, which is the only
independent claim.
Boustany discloses certain alkyl- and cycloalkyl-nitro-
benzothiazolyl disulfides as vulcanization accelerators (col.
1, line 43 - col. 2, line 2). The benzothiazolyl radical in
these compounds, unlike that in appellants’ compounds, is
substituted in the 5 or 6 position with a nitro radical.
Also, the “R” group in Boustany’s structural formula (col. 1,
lines 48-56) is alkyl or cycloalkyl and, therefore, differs
from the polar group to the right of the disulfide linkage in
the formula in appellants’ claim 3.
Kleiman discloses a method for making unsymmetrical
organic disulfides (col. 1, lines 8-16). The examiner does
not point to any particular compounds in Kleiman as being
similar to appellants’ claimed composition.
