is pertinent to the particular problem with which appellant is
involved.
Turning now to an analysis of the rejection made by the
examiner under 35 U.S.C. § 103(a). Claim 1 recites in part:
a ratchet wrench assembly . . . comprising, in
combination:
a ratchet wrench including a first end extent with a
cylindrical configuration . . . and a second end extent
having a disk-shaped head with a top circular face [and]
a bottom circular face . . .;
a ratchet wrench extender including a first end
extent with a cylindrical configuration having a first
diameter . . . an intermediate extent . . . with a
cylindrical configuration having a second diameter less
than the first diameter . . . [and] a second end extent
with a cylindrical configuration having the first
diameter . . .;
at least one cylindrical socket . . .;
whereby every outer surface of the ratchet wrench
including the first end extent and intermediate extent
and second end extent, ratchet wrench extender, and at
least one socket having a plurality of intersecting,
continuous and linear grooves of an essentially common
configuration formed therein along an entirety thereof .
. . the grooves configured to define a multiplicity of
uniform identical parallelograms for precluding slippage
(emphasis added).
