electrical insulators (Br10-11). It is argued (Br11-12) that
Ahmad does not disclose the claimed doubly asymmetric capacitor
structure which is asymmetrical not only with respect to the
metal oxide coatings, but also by use of a cathode oxide coating
that is an electrical conductor and an anode oxide coating that
is an electrical insulator (i.e., a dielectric).
The examiner admits that Ahmad's list of "conductive oxides"
may include dielectric oxides, "[h]owever, Ahmad defines
'conductive metal oxides' to include oxides (preferable) of
tantalum, niobium, and titanium" (EA7).
While not exactly clear, we assume the examiner's position
is that Ahmad discloses tantalum, niobium, and titanium oxides
whether they are actually dielectric or electrically conductive
oxides. We tend to agree. Unless it is shown by appellants that
tantalum, niobium, and titanium oxides could be made to be either
as a dielectric or electrically conductive oxide, it would seem
that the properties of these oxides are inherent and that the
disclosure of, for example, a titanium oxide coating is
sufficient to anticipate a titanium oxide coating that is a
dielectric even if it is described as being electrically
