Appeal No. 1998-0870
Application No. 08/325,015
alkoxysilane is provided on it to provide a supplemental layer
(Brief, page 4). First, with respect to the use of harmful
organic solvents, Kinoshita teaches that the organic solvent
is optional. In this regard, Kinoshita states as follows:
“The coating material for use in the formation
of the first layer of film described above is
obtained by the mixing and dispersion of
antimony doped tin oxide fine powder and black
colored conductive fine powder and a dispersant
and/or a solvent possessing a high boiling point
and a high surface tension, by means of a method
in which mixing and dispersion is conducted in
water or in an organic solvent using an
ultrasonic homogenizer or a sand mill or the
like.” (Emphases added; page 6, lines 28-32.)
Second, with respect to the centrifuging step described in
either Armes or De Boer, claim 1 on appeal does not exclude a
product that is obtained by a method including a centrifuging
step. Nor does the claim recite any amount limitation for the
steric stabilizer that would distinguish the claimed subject
matter over the applied prior art references. Third, with
respect to the coating not being subjected to being washed
away when a layer of alcoholic solution of alkoxysilane is
applied over it, we note that Kinoshita successfully applies a
second layer film of an alcoholic solution of an alkoxysilane
without any difficulty (see, e.g., Preferred Embodiment 17).
