cabinets or support type structures in that the wheels or
casters on the structures tend to dig holes in carpets and,
when it is desired to move the structures, the holes present
steep inclines that the wheels or casters must climb out of
before normal
rolling is achieved (col. 1, lines 8-15). In order to
overcome the problem, Berry teaches a pair of large
retractable wheels (38) which are lowered to raise one end of
the structure above the floor when it is desired to move the
structure from one location to another (col. 2, lines 7-26).
It is the examiner's position that it would have been
obvious in view of the teachings of Covert to modify Rice by
mounting a second wheel set approximately midway between the
front and rear of Rice's base and, in view of the teaching of
Berry, to provide the second wheel set with a larger diameter
than the first wheel set. Since Berry does not overcome the
deficiency of the combined teachings of Rice and Covert noted
above, we will not sustain the rejection of independent claim
