elongated in a first direction (the y direction) and
foreshortened in a second direction (the x direction). Column 2,
lines 5-23; Figure 1. The dimension of the resulting pixel in
the slow scan (y) direction is the same as the y dimension of the
writing dot. Column 5, lines 9-40. The dimension of the
resulting pixel in the fast scan (x) direction is determined by
the length of time that the writing dot is turned on. Column 6,
lines 8-31. Although the resulting pixels therefore will be
generally rectangular (e.g., square) with rounded corners, they
are shown as circular in Figure 6. As shown on scan line 50 in
Figure 6, visible scan dot overlap in the second (x) direction is
limited, i.e., avoided. Thus, Saito satisfies the elongating and
foreshortening step of claim 13.
Appellants argue that Saito does not teach or suggest a
method for limiting visible dot overlap. Appeal Brief at 20.
Saito does teach a method that inherently limits visible dot
overlap as explained above, whether or not Saito expresses the
same reasons as Appellants.
Appellants also argue that Saito’s pixels are not produced
directly on the recording media by the laser as recited in claims
12 and 13 because in Saito a drum is charged by a laser to pick
up ink for transfer onto a receiver substrate. Appeal Brief at
