Appeal No. 2001-0319
Application 09/005,841
support material, it would be impossible to have different
material oxides on each side, e.g., a molybdenum oxide one side
and a tantalum oxide on the other when the support material is
tantalum. Thus, Ahmad does not expressly or impliedly disclose
different oxide coatings on the cathode and anode, much less the
specific choice of oxide coatings. In addition, we agree with
appellants that the fact that none of the examples describe an
asymmetrical structure with different oxide coatings on the
cathode and anode demonstrates that one of ordinary skill in the
art would consider Ahmad to describe conventional and symmetrical
electrochemical capacitors, not an asymmetrical capacitor.
For the reasons stated above, we find the anticipation
rejection to be in error. The rejection of claims 23, 24, 27,
and 34 is reversed.
Claim 25
Hähn is applied to show a porous sintered tantalum anode.
Hähn does not cure the deficiency of Ahmad with respect to the
limitations of claim 23. Accordingly, the rejection of claim 25
is reversed.
