Appeal No. 2000-0558 Page 10
Application No. 08/912,585
Accordingly, the issue before us is whether coating of
the admitted prior art data cartridge by the method of
Hakanson would result in an electrically conductive film
coated on each surface of the base plate and connected to an
electrical ground integral with the feeding mechanism thereby
reducing electrostatic charge buildup.
As disclosed by Hakanson, the purpose of coating the
components of the cassette is for reducing the electrostatic
charge buildup which, to one of ordinary skill in the art,
would mean that the coating is electrically connected to, or
integral with, ground. Hakanson also discloses that the
coating is applied to all surfaces, and specifically that
"both interior and exterior surfaces of the cassette, reels,
spools, structural supports, and other parts of the cassette
should be coated" (column 2, lines 50-53). Thus, both sides
of the base plate as well as the feeding mechanism would be
coated and the coating would be connected to, or integral
with, ground.
