Appeal No. 1997-4428
Application 08/259,634
ordinary skill in the art at the time the invention was made
to provide the base covering 62 of DeMoore
with an electrically conductive layer connected to the
cylinder body as taught by Kobler so as to alleviate the
electrostatic charge build up problem on the cylinder surface.
Appellants argue on page 12 of the brief, that there is
no suggestion or motivation to substitute Kobler's aluminum
conductive layer 6 in the place of DeMoore's non-conductive
base covering 62. Appellants argue that Appellants' claims
require a conductive layer in direct contact with the covering
net or jacket. Appellants point out on pages 10 and 11 of the
brief that Kobler discloses a blanket cylinder with a rubber
blanket 5, a felt underlay packing 4, a non-conductive Teflon
coating 3 and an aluminum conductive layer 6.
Appellants argue that Kobler teaches that the aluminum
conductive layer 6 prevents the build up of the electrostatic
charge on the rubber blanket 5. The conductive aluminum layer
is insulated from the blanket cylinder by the non-conductive
5
