surface of the workpiece base and denying saw blade cuts 45
degrees to either side of zero-tilt without turning the workpiece
around. The separate and distinct motor and saw blade shafts of
the desk-top cutting machines defined by appellant’s Claim 1 and
described by Ito lie in separate planes. However, the separate
and distinct motor and saw blade shafts of the desk-top cutting
machines defined by appellant’s Claim 1 lie in parallel planes and
are connected by linear “transmission means” (see Figures 1 and 4
of appellant’s patent). The separate and distinct motor and saw
10 blade shafts of Ito’s desk-top cutting machines do not lie in
parallel planes. Ito solved the problem of the motor housing
abutting the top surface of the workpiece base by positioning the
distinct motor and saw blade shafts at angles acutely oblique to
each other, i.e., in intersecting planes. At the points of
intersection, there Ito’s separate and distinct shafts are
connected by an angular “transmission means” (see Figures 1 and 4
of appellant’s patent).
What would a person having ordinary skill in the art have
learned from the combined teachings of Figures 6 and 7, Johnson,

skill in the art have learned from the combined teachings of Ito,
