Appeal No. 2003-0786
Application 09/059,712
As noted on page 1 of the specification, appellant’s
invention relates to a wrench and fastener arrangement with
complementary driving surfaces thereon that generate a higher
torque in the loosening direction than in the tightening
direction. More specifically, the invention involves an
asymmetrical fastening and wrenching system comprising a fastener
(e.g., Fig. 6) and a wrench (e.g., Fig. 5), wherein the fastener
has a single fastener periphery and the wrench has a single
wrench periphery designed and configured to engage the single
periphery of the fastener, and wherein each of the fastener
periphery and the wrench periphery includes a plurality of
tightening surfaces and a plurality of loosening surfaces formed
thereon. Independent claims 24 and 42 are representative of the
subject matter on appeal and a copy of those claims can be found
in Exhibit A of appellant’s brief (Paper No. 51).
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
1(...continued)
matter of that application and this one, the examiner should
consider, during any further prosecution of the present
application, the possibility of a provisional obviousness-type
double patenting rejection.
