of the housing, in our view there would have been insufficient
motivation for one with ordinary skill in the art to use Haskins'
multiple recessed grooves in either Aoki or Kirchgessner.
In Haskins, the multiple grooves are designed for
alternative line cords. A long line cord for desk mounting would
go into the long groove, and a short line cord for wall mounting
would go into the shorter groove (column 1, lines 15-23). Where
the same cable is used as in the pointing devices of Aoki and
Kirchgessner, one with ordinary skill in the art would not have
been led to use Haskins' multiple grooves.
Even assuming that Haskins' multiple grooves for the line
cord (not the handset cord) would have been reasonably suggested
for use with the cable of Aoki or Kirchgessner, Haskins would not
have reasonably suggested the specific arrangement of the
multiple channels as required by the claimed invention.
According to claim 1, the recessed channels must (1) extend
orthogonally relative to each other, and (2) intersect where the
cable passes through the bottom wall of the housing.
In Haskins' Figure 3 embodiment, the optional groove for
wall mounting is not shown and thus to say that the channels
would meet the requirements of claim 1 amounts to mere
speculation and is improper. In Haskins' Figure 1 illustration
