Appeal No. 95-1167
Application 07/928,027
Claims 1, 2, 4, 5, 7 to 10 and 13 to 19 stand rejected under
35 U.S.C. § 103 as being unpatentable over Godo in view of
Kosugi.
Claims 6, 8, 9, 11 and 12 stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Godo in view of Kosugi further
in view of Rose or O'Brien.
Claims 1, 2, 4, 5, 7 to 10 and 13 to 19 stand rejected under
35 U.S.C. § 103 as being unpatentable over page 1, lines 26 to 29
of appellants' specification in view of Kosugi.
We cannot sustain these rejections.
Missing from the references is any teaching or suggestion
that chitosan can be chemically linked to a cellulosic casing
material. According to appellants' specification, page 4, lines
13 to 24, the chemical linking results from using monoaldehydes
and dialdehydes such as formaldehyde, glyoxal or glutardi-
aldehyde. For this reason, we are compelled to reverse the
examiner's rejections.
REVERSED
