Appeal No. 1998-1823 Page 4
Application No. 08/414,259
Unlike the examiner, however, our review of the applied
references including the referred to portions of Kavalir does
not reveal any teaching or suggestion of dipping a form
already covered with a layer of elastomeric material (casing)
in a solution including polyvinyl alcohol and a thickener as
required by the appealed claims. While Kavalir does disclose
dipping a form covered with a latex material in a slip finish
of pre-cured resin-rubber latex (column 3, line 30 through
column 5, line 8), we find no teaching of using polyvinyl
alcohol and a thickener containing solution for coating a
casing in Kavalir.
We are mindful that Kavalir discloses dipping the form in
a coagulant solution containing alcohol and a mold release
powder (column 4, lines 46-49), but that step occurs prior to
coating the form with an elastomeric material to form a
casing. Hence, even if the applied reference teachings are
combined, the herein claimed process would not be the result.
Consequently, for the reasons outlined above and as developed
in appellants' brief (pages 4-7), we will not sustain the
stated rejection.
