Appeal No. 2006-2084
Reexamination Control No. 90/006,360
Kyocera teaches a 2.5 mm diameter 60° countersunk screw for mounting a
profiling insert with a 0.250" IC diameter. The screw head has a maximum width
of 0.14" (= 3.56 mm), which is 56% of the IC diameter. The maximum fastener
aperture would be approximately equal to the head diameter so that the head fully
bears against the countersink. Although Kyocera is a profiling tool, one of
ordinary skill in the machine tool art had sufficient skill to apply teachings of
profiling tools to vertical tools and vice versa, especially since the mounting of
profiling inserts, as in Kyocera, and vertical inserts, as in Max Bar and ETCO, are
so similar. It is noted that the preferred embodiment of the '400 patent uses a
2.5 mm screw (col. 5, lines 39-42). The fastener aperture and fastener in Kyocera
meet the limitations of a fastener aperture having a "diameter less than
approximately 70% of the diameter of the inscribed circle," as recited in claims 1,
2, and 16-18; a threaded fastener head "having a maximum diameter less than
approximately 70% of the diameter of the inscribed circle," as recited in claims 1
and 2; and a fastener aperture with a "maximum diameter within the range of
approximately 3 mm through 4.5 mm," and a countersunk head "having a
maximum diameter within the range of approximately 3 mm through 4.5 mm," as
