First, regarding independent claim 1, the claim sets
forth certain requirements for the claimed cover, including
that the front and rear panel portions have “small apertures”
and that air is allowed to flow “therethrough while shielding
electromagnetic waves emitted from at least said control
circuit board.” It is appellants’ position that Sarraf fails
to disclose such apertures in the front portion and that, even
applying Dodson, there is no teaching or suggestion in either
of the references for providing the claimed cover with
apertures which act to allow air cooling and to shield
electromagnetic waves.
It is our view that Dodson clearly teaches the
desirability of providing apertures in the front and rear
portions of the cover of an analogous device for cooling
purposes. See Figures 1 and 2 of Dodson where slots 32 are on
the front of the housing while the arrows near reference
