pixel location for an enable signal to latch and retain data
which is destined for it.”
While we recognize the differences between the instant
disclosed invention and that disclosed by Green, we agree with
the examiner that independent claims 4 and 21 are of such
breadth that the claimed subject matter is anticipated (claim
4) and made obvious (claim 21) by Green.
While appellants argue that there is no addressable logic
circuitry at each pixel element in Green which can identify
its unique address in a data stream appended to gray scale
data for that pixel circuit element, claims 4 and 21 do not
require such a “unique” address.
With regard to the logic circuitry, claim 4 requires only
that there is “addressable logic circuitry at each pixel
circuit element for receiving gray scale data....” Clearly,
the counters, 2, of Green may be said to receive gray scale
data [see column 2, lines 22-24]. Also, these counters are
“addressable,” as broadly claimed, in the sense that something
is addressing them in order to load the required data. In
Green’s case, each pixel circuit instructs, or “addresses,” an
adjacent circuit that it is next to be loaded. Thus, as
