examiner considers that such ranges for the flooding angle
would have been an obvious matter of design choice to one of
ordinary skill in the art, since a receptacle whose walls are
inclined at such angles would provide a receptacle which
concentrates the bait at the center of the receptacle through
the forces of gravity acting upon the bait within the
receptacle.
In this instance, we are in agreement with the examiner.
Based on the teachings in Wefler, in the paragraph bridging
columns 4 and 5 thereof, and the showings in Demarest '229, we
consider that it would have been obvious to one of ordinary
skill in the art to provide the insect bait station of Wefler
with a concave receptacle in the form of an inverted conical
shape so as to achieve the end desired by Wefler, i.e., of
having even minimal amounts of liquid bait (156) on the floor
(118) drain toward the porous pad (158) and thereby be
sufficient to contact the porous pad for transport upwardly
toward the upper surface (154) thereof. As for the ranges of
flooding angle set forth in claims 5 through 7 on appeal, we
share the examiner's view that such ranges would have been an
