Appeal No. 1998-1247
Application No. 08/445,165
The Examiner’s position is the stabilization of the known combination of
fluoroglycofen-ethyl and isoproturon would have been obvious. The Examiner’s position
is reproduced below:
EP 388,867 [sic, Schlicht] teaches that isoproturon may be
formulated into water dispersible granules.
The Ag. Handbook teaches fluoroglycofen-ethyl and isoproturon are
known to exist in combination.
It would appear to have been obvious to one of ordinary skill in the
herbicidal art to stabilize the known water dispersible isoproturn granule
with an additional active ingredient which is known to be formulated with
isoproturon wherein a herbicidally effective granule would ensue.
(Answer, pp. 4-5).
The subject matter of claim 17 is directed to water-dispersible granules of
suspoemulsions. The suspoemulsion of claim 17 is an emulsified composition including
an aqueous dispersion of a pesticidally active substance having a melting point more than
o
65 C, a solution of a second active pesticidally active substance having a melting point
o o
below 65 C and a solvent which has a boiling point above 170 C. Isoproturon is an
example of a high melting point substance. Fluoroglycofen ethyl is an example of a low
melting point substance. (Specification, p. 3).
The Examiner cites The Agrochemicals Handbook as evidence that the
combination of fluoroglycofen-ethyl and isoproturon is known to those skilled in the art.
The Examiner has not indicated that a suspoemulsion of fluoroglycofen-ethyl and
isoproturon is known. The Examiner has not indicated that the granulation of
