Appeal No. 1997-0090
Application No. 08/083,183
The references of record relied upon by the examiner are:
Whiting et al. (Whiting) 4,938,842 July 3,
1990
Prough 4,946,556 Aug. 7, 1990
Peter et al. (Peter) 5,145,557 Sept. 8, 1992
Lundgren et al. (Lundgren) 0,402,335 Dec. 12, 1990
(European Patent Application)
The appealed claims stand rejected under 35 U.S.C. § 103
as unpatentable over Lundgren and Peter “with or without”1
Prough or Whiting. The appealed claims also stand rejected
under the same section of the statute over “ADMITTED PRIOR ART
(Brief, page 8, lines 9-17)” in view of Whiting “with or
without Prough”. See the answer at page 4.
The subject matter on appeal is directed to a process for
bleaching a chemical paper pulp by a sequence of treatment
steps to obtain levels of brightness of at least 89E ISO in
the treated pulp which is alleged to be “not heretofore
obtained by prior art processes”. See the brief at page 4.
1In his answer at page 5, the examiner indicates that
Lundgren is the “primary reference”.
