skill in the art to use their polymers in the processes of
Anderson, Howell, Jr. and Bozzi. In addition, the teachings
pointed out by the examiner (answer, pages 6-8) by Anderson
(col. 2, lines 14-17) that any resinous polyepoxide is useful
in his process if it can be dissolved in an organic solvent of
limited water solubility such that it is emulsifiable into an
aqueous medium by means of a surfactant, and by Erickson (col.
12, lines 12-13) and Udipi (col. 3, lines 44-66) that their
epoxidized polydiene block polymers can be used in both
organic solvent systems and water dispersions, would have
provided one of ordinary skill in the art with a reasonable
expectation of success in using the Erickson and Udipi
polymers in the processes of Anderson, Howell, Jr. and
Bozzi wherein the epoxy resin is dissolved in an organic
solvent and then is dispersed in water. Accordingly, we hold
that the invention recited in appellants’ claim 11 would have
been prima facie obvious to one of ordinary skill in the art
over the applied references. See In re Vaeck, 947 F.2d 488,
