the time applicants’ invention was made, to use a copolymer of
vinylpyrrolidone and vinyl acetate or a polyvinylpyrrolidone
grafted with butene as the binder in WDG systems. For example,
the publication “Agrimer™ AL Polymers For Agricultural
Formulations” discloses that the Agrimer™ AL Polymers described
therein are excellent adhesives. Likewise, the publication
“Agrimer™ VA Polymers For Agricultural Formulations” discloses
that the Agrimer™ VA Polymers described therein are good
adhesives and also function as binders in wet granulation
processes and binders for seed coatings.
CONCLUSION
In conclusion, the examiner’s rejections under 35 USC § 112,
second paragraph, and 35 USC § 103, are reversed. We enter a new
ground of rejection of claims 2, 4 through 6, 8, and 9 under 35
USC § 112, second paragraph. We also recommend that the examiner
