Appeal No. 2006-2084
Reexamination Control No. 90/006,360
Between Nikcole and the independent claims
One difference between the subject matter of independent claim 1 and
Nikcole is that Nikcole does not disclose the limitations indicated by underlining in
"two sides of the insert each fully engaging a respective tool-supporting surface of
the shank without any substantial portion of the two sides extending beyond the
respective tool-supporting surfaces," which were added by amendment in the
reexamination to define over Nikcole (Paper filed December 31, 2004). If the tool
shank is given weight in independent claim 16, this is the sole difference between
the subject matter of claim 16 and Nikcole. The long side of the Nikcole insert
does not fully engage the tool-supporting surface and extends beyond the tool-
supporting surface. The other difference between claim 1 and Nikcole is that
Nikcole discloses a 3 mm countersunk head screw, but does not disclose the head
diameter of the screw and, so, does not expressly teach "a head having a maximum
diameter less than approximately 70% of the inscribed circle."
One difference between the subject matter of independent claim 2 and
Nikcole is that Nikcole does not teach "wherein the first and second tool-
supporting surfaces are oriented at an angle of approximately 35° relative to each
