Appeal No. 1997-1164
Application No. 08/279,304
U.S.C.
§ 103 as being unpatentable over Nagase in view of Kashima.
Reference is made to the briefs and the answer for the
respective positions of the appellant and the examiner.
OPINION
We have carefully considered the entire record before us,
and we will sustain the 35 U.S.C. § 102(b) rejection of claims
2 and 4 through 6, and we will reverse the 35 U.S.C. § 103
rejection of claims 1 through 3, 7 and 8.
The optical display of Nagase (Figures 1 and 6) uses a
polymer dispersed liquid crystal material 24 (translation,
page 3) that can be placed into a transmissive state by
application of an electric field, and into a reflective state
by reduction of that field (translation, pages 7 and 10). The
optical display in Nagase has red, green and blue color
filters 16R, 16G and 16B, respectively, through which the
reflected light passes. Thus, the 35 U.S.C. § 102(b)
rejection of claim 2 is sustained because all of the
limitations of this claim read on Nagase.
The 35 U.S.C. § 102(b) rejection of claims 4 through 6 is
sustained because appellant has chosen to let these claims
