Interference No. 103,169
FINAL DECISION
This interference concerns a process for preparing a biaxially oriented film of a rigid
rod heterocyclic liquid crystalline polymer. The subject matter at issue is defined by a
single count which is identical to claim 1 of the Chenevey et al. patent.
The count reads as follows:
Count 1
A process for preparing a biaxially oriented film of a rigid rod heterocyclic liquid
crystalline polymer, comprising:
(i) providing a dope from a polymerization mixture of a rigid rod
heterocyclic liquid crystalline polymer and a solvent;
(ii) extruding the dope to form a film;
(iii) imparting biaxial orientation to the film to increase the transverse
strength thereof;
(iv) solidifying the biaxially oriented film; and
(v) washing the solidified film to remove the solvent.
Chenevey et al. patent claims 1-26 and Baars et al. claims 23-45 correspond to the count.
Upon declaration of the interference, Baars et al. was accorded benefit of their two
earlier filed U.S. applications, by virtue of which, Baars et al. was declared senior party in
this proceeding.
During the preliminary motion stage of this proceeding, Baars et al. filed a motion
