Application No. 08/176,187
macromolecular compounds (column 1, line 60 column 2, line 13).
Although Naarmann discloses that the amount of the macromolecular
compound can be from 10 to 90 weight percent (column 2, line 66
to column 3, line 2), Naarmann does not specifically describe the
ionomeric or ionophoric block copolymer containing an ion binding
segment as in the present invention or Bates. Additionally,
Naarmann teaches solution or suspension polymerization, followed
by precipitation, filtration, and washing (column 3, line 61 to
column 4, line 2; Examples 1-14). Naarmann’s polymerization
technique is quite different from the electro-oxidative
polymerization disclosed in Bates, where polypyrrole film that is
deposited onto an electrode as pyrrole is polymerized. Under
these circumstances, we determine that one of ordinary skill in
the art would have found no motivation, suggestion or teaching
from Naarmann to increase the amount of tri-block copolymer in
Bates. In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d 1614, 1617
(Fed. Cir. 1999); In re Fine, 837 F.2d 1071, 1075, 5 USPQ2d 1596,
1600 (Fed. Cir. 1988).
Cross discloses the use of dopant polymers to influence the
chemical and/or physical properties of the conductive polymer
(page 1, line 62-81; pages 2, lines 9-31; page 2, lines 64-102).
Although Cross teaches the use of relatively high amounts of the
dopant polymer (e.g., 5 grams of the dopant polymer per 0.06 mole
