Appeal No. 99-0643 Page 5
Application No. 08/828,225
In rejecting the claims, the examiner relies on Nagy as
the primary reference. Nagy discloses "a security lock for a
door or other closure" (column 1, lines 7 and 8) comprising a
conventional lock cylinder (12) including a barrel (16) having
a slot (18) formed therein for receiving a key and a rigid
tube (20) attached to the lock cylinder (12), the tube (20)
further including a pair of diametrically opposed openings
(32) which receive the hasp (34) of a padlock (36). The hasp
extends across the interior of the tube (20) to prevent a key
from being inserted into the slot (18) and to prevent access
to the slot by picking instruments (column 2, lines 47 through
60). A special key (24) having a blade or shank (26) provided
with an extension (28) of substantially the length of the tube
(20) is required to enable a person to operate the lock by
inserting the shank (26) into the slot and then rotating the
key and barrel (column 2, lines 36 through 46). The examiner
concedes that Nagy does not disclose combination of the
security lock with an ignition switch keyway and the security
lock having a pair of separate, planar flanges being parallel
to the length of the keyway (answer, page 3).
