characteristics.
As evidence of obviousness of the herein claimed subject
matter, the examiner relies on the Hayashi patent. Although
each of the appealed claims requires a negative electrode
formed from materials other than lithium metal, Hayashi's
invention is directed to a secondary cell using a negative
electrode formed from lithium. Referring to Figure 1 of
Hayashi, it can be seen that the negative electrode of the
Hayashi cell specifically includes lithium metal 7 along with
carbonaceous material 6. Indeed, the entire object of Hayashi
is the improvement of a lithium-containing cell. Thus,
nothing in the Hayashi reference suggests any reason to use
the prior art carbonaceous materials without lithium metal.
Referring to the
disclosure of Hayashi at column 1, lines 12 through 15, which
indicates that a secondary cell formed from a conjugated
pyrolysis residue of a high polymer has been used as either
the anode or a cathode as proposed in Japanese Patent
Publication No. 58-93176 published June 2, 1983, the examiner
contends that the elimination of lithium from the Hayashi
patented secondary cell represents nothing more than the
