Appeal No. 95-2233
Application 07/978,014
INTRODUCTION
Initially, we observe that the prosecution history of this
application and the briefings before the Board are not a model of
clarity. For this reason, we contemplated remanding to the
examiner. On reflection, however, we decided that we can resolve
the issues presented on appeal and, in the interest of judicial
economy, we shall do so.
REPRESENTATIVE CLAIM
Claim 2, which is illustrative of the subject matter on
appeal, reads as follows:
2. A free-flowing, non-dusting water dispersible granule of
an active agricultural chemical having low friability and
effective crush strength for delivery to a desired site as a
stable suspension in water, without deleterious foaming,
comprising an active agricultural chemical and about 1-6% by
weight thereof of a binder which will dissipate its binding
action when the granule is immersed in water which is a copolymer
of (a) polyvinylpyrrolidone and (b) a comonomer selected from
butene and vinyl acetate, and mixtures thereof, and optional
agents selected from the group consisting of defoamers, wetting
agents and dispersing agents.
