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

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
