wound separator portion. The electrode that includes the wound
separator portion is located rearwardly of the leading edge
portion of the second electrode during the winding as depicted in
drawing Figure 5 of Machida. The spool is removed after the
winding is complete resulting in a tightly wound spiral electrode
assembly, which assembly can be thereafter incorporated in a
cylindrical cell. See column 4, line 58 through column 5, line
51 of Machida.
The examiner recognizes that Machida does not employ a
rectangular mandrel having a pair of opposite and planar faces in
forming an electrode assembly as required by claim 1. Nor does
Machida teach or suggest that the electrode assembly should be
formed into a prismatic shaped electrode assembly having a
rectangular pocket or two substantially flat sections of longer
electrode facing each other. Nor does Machida teach a cell
including such a prismatic electrode assembly, as claimed by
appellant.
In an attempt to remedy the acknowledged deficiency of
Machida (final rejection, page 4), the examiner additionally
relies on the teachings of Takeuchi.
Takeuchi discloses a prismatic cell with the shaping thereof
being done simultaneously with the winding thereof by using a
