Appeal No. 2002-1914
Application 09/247,889
lines 21-24) also teaches machining a desired bevel (38)
longitudinally of the rails (6) at a peripheral part of the
slider ABS (note Fig. 12). Thus, both the APA and Ellenberger
teach lapping or other machining to form a chamfer at the
peripheral part of a magnetic head and we see nothing in the
prior art which would have led a person of ordinary skill in the
art to any other technique for forming such chamfered surfaces on
the peripheral portion of a magnetic head.
Since we have determined that the teachings and suggestions
which would have been fairly derived from the APA, Ellenberger
and Sawada would not have made the subject matter as a whole of
claims 1 through 3 on appeal obvious to one of ordinary skill in
the art at the time of appellant’s invention, we must refuse to
sustain the examiner’s rejection of those claims under 35 U.S.C.
