Appeal 2007-1764
Application 10/391,320
Onda discloses the positively charged polymer may be
poly(diallyldimethylammonium) and that organic polymer ions such as those
derived from polythiophene can also be used in the present invention (col. 4,
ll. 48-51). Onda discloses the suitability of using mixtures of polymer ions
(complexes) for formation of the coating solution (Onda, col. 5, l. 58- col. 6,
l. 25). The Examiner recognized that Onda did not specify the use of
poly(3,4-ethylene dioxythiophene) in the negatively charged
layer. The Examiner determined that Ho teaches polythiophene conductive
polymer complex, specifically poly(3,4-ethylene
dioxythiophene)-poly(styrene sulfonate), may be used as a conductive
anionic material in a layer-by-layer process to form multilayer films
(Answer 4). Appellants did not dispute that Onda teaches a dielectric
support material that is coated with multilayer thin films Onda and Ho
teaches polythiophene conductive polymer complex.
Appellants’ principal argument is “Onda’s listing at col. 4, lines 48-51
of ‘polymer ions such as those derived from polythiophene’ in the last-
quoted passage stands alone and is not, as the Examiner argues, a statement
or suggestion that both anionic and cationic forms of ‘polythiophene’ exist
or can be used.” (Br. 15). Appellants also argue there is no suggestion or
motivation to combine the teachings of Onda and Ho (Br. 16-20).
We do not find Appellants’ arguments persuasive. Onda teaches a
dielectric support material that is coated with multilayer thin films. Onda
teaches organic polymer ions such as those derived from polythiophene are
suitable for use in the invention. A person of ordinary skill in the art would
