Appeal No. 1998-0883
Application 08/498,570
The problem is that the Examiner finds that Usami does
not specifically state that signals are separated by 1/8
period and states (FR4; EA7):
It would have been obvious to one of ordinary skill in
the art to separate signals by 1/8th phase simple [sic]
as a matter of design choice. Furthermore, one of
skill in the art would have known to reprogram the
delay pattern in the phase change quantity pattern
generator 204 in order to get the 1/8 phase delay as
desired.
Although Appellant admits that Usami discloses the 1/8
period phases, Appellant submits that the Examiner's
reasoning is conclusory and improper (Br5-6).
Since we find the 1/8 period phase limitation taught by
Usami, it is unnecessary to address the Examiner's
reasoning.
Differences among initial phases
The real issue is whether Usami discloses "means for
selecting one of the generated clock signals for each color
on a scanning line basis so as to produce the respective
assigned screen angles and to cause differences among
initial phases for the respective colors" (emphasis added).
The underlined language refers to the fact that the eight
phase signals T0-T7 in Appellant's Figure 2 are selected so
