Appeal No. 2000-0820 Page 9
Application No. 08/978,625
First, the examiner relies on White in view of DeVrou to
provide the teaching of a non-slip grooved surface over every
outer surface of the ratchet wrench assembly of White. DeVrou
is directed to a wrench extender with a removable non-slip
grip 50 which is of a “relatively short length . . . [that]
will universally fit extensions of all greater lengths”
(DeVrou, col. 4, lines 13-14). Therefore, an extender longer
than the one shown would result in a portion of the extender
not being covered with the non-slip grip. DeVrou, at best,
could only provide a teaching to apply a removable non-slip
grip to a wrench extender and not to a wrench and socket as
asserted by the examiner. The disclosure in DeVrou of having
an extension with a knurled shank (col. 4, lines 14-18), is
also of little help to the examiner’s position. Furthermore,
DeVrou does not disclose the other
deficiencies noted in White of a wrench having a disk-shaped
head with circular top and bottom faces or an extender having
a second
