Appeal No. 96-2665 Application 07/975,811 Appellant's claimed invention is directed to compositions that provide stable microemulsions in aqueous medium that are used to coat a film on a substrate. The resultant film exhibits water fastness even though the film-forming composition is aqueous based. According to appellant, the claimed compositions are particularly useful for coating agriculturally active ingredients, such as herbicides. The compositions of the present invention comprise a long chain alkylpyrrolidone of the recited formula, an anionic surfactant, and a film-forming water insoluble graft polymer of N-vinylpyrrolidone and an "-olefin. Appealed claims 10, 15, 17, 18, 20-26, 28-40 and 45-51 stand rejected under 35 U.S.C. � 112, second paragraph. In addition, claims 10, 15, 17, 18, 20-26, 28-40 and 45-51 stand rejected under 35 U.S.C. � 112, first paragraph, as being based upon a specification that fails to provide an adequate written description of the invention. We have carefully reviewed the respective positions advanced by appellant and the examiner. In so doing, we find that the examiner's rejections are not sustainable. We consider first the examiner's rejection of the appealed claims under 35 U.S.C. � 112, second paragraph. According to the -2-Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
