Appeal No. 1997-0863
Application 08/456,001
Claims 30 and 31, the only other claims pending in this
application, were not rejected by the examiner in the final
rejection, however, appellants’ brief (Page 2, Paper No. 29,
filed September 9, 1996) indicates an assumption that these
claims are rejected. The examiner’s answer (Paper No. 30,
page 4) includes claims 30 and 31 in the rejection under 35
U.S.C. § 102(b). Thus, it is our view, and apparently that
of appellants and the examiner, that claims 1 through 14 and
22 through 31 are before us on appeal.
Appellants’ invention relates to a static mixer for
thoroughly and efficiently mixing two or more fluids of
varying viscosities. Claims 1, 9, 14, 25, 26 and 29 are
representative of the subject matter on appeal and a copy of
those claims is appended to this decision.
The prior art references of record relied upon by the
examiner in rejecting the claims on appeal are:
