Appeal No. 97-0593
Application 08/365,906
substantially linear side edges that are aligned orthogonally
with respect to the cutting edges (16) of the cutting insert
therein merely because Warren shows a cutting insert having
recesses (18) with linear side edges that are so oriented, we
find such a position to be untenable.2
Like appellant, we find the disclosure of the Stashko
patent to be inconsistent and generally ambiguous with regard to
the width dimension of recesses or depressions (36) therein
relative to the width dimension of the groove defined by surfaces
(20, 24) of the cutting insert. All of the top plan views of the
inserts in Stashko (i.e., Figures 1A, 6 and 7) show the width
dimension of recesses or depressions (36) to be smaller than the
width dimension of the groove adjacent the cutting edges of the
inserts. However, sectional views seen in Figures 2 and 5 of
the patent inexplicably appear to show the width dimension of a
recess or depression (36) as being larger than the width
dimension of the groove. In light of these inconsistencies, it
2Like the examiner, we note that while the specification
in Stashko uses reference characters to refer to the various
elements of the cutting inserts described therein, the drawings
of Stashko have no reference numerals associated therewith.
