oxygen containing functional group and constitutes a part of
the active carbon.
Nor can we state that active carbon in the form of fiber
which "consists essentially of pitch-based oxidized activated
carbon fiber" as specified in claim 15, includes a fiber which
has been after treated with Fe ion so as to function in a+2
chemically distinct manner. Hence, the disclosure of Oikawa
is not sufficient to teach the oxygen content limitations of
claim 15 also omitted by Matsuo, the primary reference relied
upon by the examiner.
Finally, we agree with appellants' analysis of the
teachings of van Montfoort in appellants' Brief, in the
paragraph bridging pages 12 and 13. The reference is not only
drawn to non-analogous art, it also fails to state the oxygen
content of the activated carbon fiber. Van Montfoort subjects
activated carbon fiber to oxidation, but thereafter deposits
catalytically
active metal on the activated carbon support and utilizes it
in entirely distinct processes. The person having ordinary
skill in the art at the time the invention was made would have
had no reason to look to the teachings of van Montfoort or
