Application 08/379,722
securing the semi-conductive base covering around the
substrate support surface and in electrical contact with the
rotatable member." Furthermore, we note that the only other
independent claim, claim 11, recites "supporting the freshly
printed side of the substrate on a semi-conductive base
covering disposed on the support cylinder; conducting
electrostatic charges from the freshly printed substrate to
the semi-conductive base covering; and, conducting
electrostatic charges from the semi-conductive base covering
to the support cylinder." Therefore, we find that Appellants'
scope of the claims before us require that the underlying low
friction, conductive transfer member makes direct electrical
contact with the underlying conductive sheet support surface
of the transfer cylinder.
In col. 1, lines 14 through 37, Köbler teaches that
it is necessary or desirable to cover the surface of the
rubber blanket cylinder with a protective coating since the
cylinder is in contact with aggressive chemicals. Köbler
discloses that typical coatings are nickel, chromium, and
