Appeal No. 1999-1770
Application 08/750,625
insecticide spraying system to such a henhouse, since it is
disclosed as generally applicable to caged chicken houses
(col. 1, line 10).
Claim 15 recites that the pest-control agent "is
simultaneously applied to said feces floor and said feces
board." In the Cunningham system, it is disclosed that the
insecticide, which is atomized into the atmosphere, "condenses
on surfaces of the premises" (col. 2, line 66) and gives the
beneficial result of "larvae free surfaces in the premises"
(col. 3, line 5). As stated in the preceding paragraph, it
would have been obvious to utilize the Cunningham system in
henhouses generally, and according to the APA, known henhouses
have feces boards therein (page 1, lines 18 to 23).
Therefore, in using the Cunningham system, the method recited
in claim 15 would be performed because the atomized
insecticide would condense on the surface of the feces boards
as well as on the feces floor.
Conclusion
11
