Claims 1, 3-8 , 10-16, 30-31 and 33-42 stand rejected under 35 U.S.C.§ 103 as
unpatentable over Kampf in view of either the Textbook of Polymer Science or Polymer
Processes.
After careful consideration of the arguments of appellants and the examiner and of
the record before us, we find that we cannot sustain the examiner’s rejection. Accordingly,
we reverse. Our reasons follow.
The instant claims are directed to a coating composition that comprises , at a
minimum, four (4) ingredients, to wit, (1) an intrinsically electrically conductive polymer in an
amount effective to provide antistatic properties when coated onto the plastic film (5-90%
by weight to dry weight of coating composition), (2) a binder other than a conductive
polymer and additive in an amount effective to improve the adhesion of the coating to the
plastic film (1-90% by weight to dry weight of coating composition), (3) a solvent, and (4)
an additive having low adhesion to a metal layer in an amount effective
2Claims 3 and 4 refer to concentrations as based on the dry weight of the coating
“agent”. The term agent does not have any antecedent support. It would appear that
appellants are referring to the coating or coating composition. These claims should be
corrected.
