Appeal No. 1996-0672
Application No. 08/164,774
The sole reference relied upon by the examiner is:
Yamazaki et al. (Yamazaki) “Chiral Trifluoromethylated 2-
Butenolides for the Construction of 6-Deoxy-6,6,6-
trifluorosugars”, J. Chem. Soc., Chem. Commun., pp. 55-57,
1992.
The appealed claims stand rejected under 35 U.S.C. §
102(b) as anticipated by, or in the alternative, under 35
U.S.C. § 103 as obvious over Yamazaki.
We cannot sustain the stated rejections.
The subject matter on appeal is directed to certain
optically active fluorinated compounds of the general formula
shown in appealed claim 1. These compounds are described as
useful, inter alia, as “raw materials” for ferroelectric
liquid crystals, i.e., liquid crystalline materials comprising
at least one chiral center and displaying a ferroelectric
(chiral smectic) phase.
Appellants do not dispute the examiner’s factual
determination that compound 13 disclosed at page 56 of
Yamazaki anticipates (35 U.S.C. § 102) or alternatively
renders obvious (35 U.S.C. § 103) the herein claimed
compounds. Appellants’ basic argument against the prior art
