Appeal No. 93-4332
Application 07/707,717
DECISION ON APPEAL
This is an appeal from the rejection of claims 1 through
15. Claims 16 through 22 stand withdrawn from consideration.2
See Paper No. 4.
Appellant’s claimed invention relates to a process for
improving the solubility of a curable bisimide/triene mixture in
an organic solvent. According to the claimed invention, a
mixture of a bisimide of an unsaturated dicarboxylic acid and a
triene is provided. The mixture is subjected to a non-gelling
elevated temperature for a time sufficient to increase the
viscosity of the mixture and to enhance the solubility of the
mixture in an organic solvent. According to the specification, a
curable bisimide solution is provided which comprises a
partially-cured bisimide and a reactive triene which is capable
of unhindered Diels-Alder reaction with the bisimide and an
isolated double bond (specification, page 2, lines 14-17).
Still, according to the specification, triene as a modifier of
2We note Appellant’s statement (brief, page 1) that the
appeal is from the final rejection of October 28, 1992 (Paper No.
8). As Applicant seems to appreciate, the final rejection was
withdrawn in favor of a non-final rejection mailed January 25,
1993 (Paper No. 10). From the record, it is clear that this
appeal is from the non-final rejection and not the withdrawn
final rejection. Of course, the appeal from a non-final
rejection is proper since the claims have been twice rejected, 37
CFR § 1.191(a).
