Appeal No. 95-0073
Application 07/896,154
Claim 1, which is illustrative of the subject matter on
appeal, reads as follows:
1. A process for preparing a second dextrose composition
having a solids content of at least 99% dextrose comprising
nanofiltering a first dextrose composition having a solids
content of about 80 to 97% by weight dextrose and at least 2% of
saccharides selected from the group consisting of di-saccharides,
trisaccharides and mixtures thereof; and
recovering as the permeate said second dextrose containing a
solids content of at least 99% dextrose. [Emphasis added.]
The references relied on by the examiner are:
Zupancic (Zupancic '122) 4,429,122 Jan. 31, 1984
Zupancic et al. (Zupancic '953) 4,747,953 May 31, 1988
The issue presented for review is whether the examiner erred
in rejecting claims 1 through 14 under 35 U.S.C. § 103 as
unpatentable over the combined disclosures of Zupancic et al.
('953) and Zupancic ('122).
