Application No. 09/981,975
Remand to the Examiner
This case is remanded to the examiner for consideration of the
following matter. Claim 1, as interpreted, calls for a tool
comprising an opening having planar surfaces, connection surfaces
connecting the planar surfaces at their ends, each connection
surface having convex surfaces and a concave surface, with the
convex and concave surfaces having the same radius.
The Figures 5-7 embodiment of Colvin comprises a tool
comprising an opening having planar surfaces 32’ and connection
surfaces connecting the planar surfaces at their ends. Each
connection surface comprises a pair of convexly curved engagement
surfaces 36’ of radius R2 connected to an associated planar surface
32’, a concave connecting surface 42’ of radius R3, and a pair of
flat surfaces 34’ connecting the convexly curved engagement
surfaces to the concave connecting surface 42’.
Colvin’s description of the Figures 5-7 embodiment at column
7, lines 5-33, includes the disclosure at lines 8-18 that the
radius R2 decreases in length from the open axial end 46’ toward
the closed axial end 44’. This is illustrated in Figures 6 and 7,
where a comparison of R2 in each drawing figure reveals that R2 as
shown in Figure 6 is substantially greater than R2 as shown in
Figure 7. It is also noted that connecting surface 42’ has
