Appeal No. 97-2612
Application 08/392,766
the concave/convex bearing arrangement of FR with a flat
bearing surface, like that taught by EPA, so as to allow for
the installation of cutting blades without chip breakers
(e.g.[,] concave surfaces) for cutting applications such as
wood and composite materials" (answer, pages 3 to 4). How-
ever, it is not evident why one of ordinary skill would
want to install blades without chip breakers, and the examiner
does not identify, nor do we find, any teaching or suggestion
in the applied prior art of the desirability of such a fea-
ture. While the clamping of a cutter blade between flat
surfaces is known, as disclosed by EPA, we find no teaching or
suggestion in the prior art which would have
motivated one of ordinary skill to employ such flat surfaces
on
the blade 7 and clamp 8 of FR instead of FR's cylindrical
bearing surface 12 on the clamp and concave face on the cutter
blade. Absent evidence of a suggestion to combine, the rejec-
tion cannot be maintained.
