Appeal No. 2005-1538
Application No. 09/950,654
the cellulose by an amino or any other group, and is not
attached at all. Appellant refers to several disclosures of
Jewell in support thereof. Brief, pages 6-7.
On page 7 of the brief, appellant argues that the
nitroxides in Jewell are not employed as light stabilizers or
yellow inhibitors; they are employed as oxidants. Appellants
conclude that Jewell contains no teachings whatsoever relevant
to lignocellulosic materials and contains no teachings relevant
to the problem of yellowing of lignocellulosic materials or
brightness loss in lignocellulosic materials. Brief, pages 7-
10.
In response, beginning on page 4 of the answer, the
examiner disagrees that Jewell does not teach to treatment of
lignocellulosic material. The examiner states that Jewell
teaches treating “lower cost market pulps” and refers to column
4, lines 12-13 in this regard. The examiner also finds that
Jewell teaches that the invention is directed to fibrous
carboxylated cellulose products including bleached and
unbleached kraft hardwood or softwood pulps and refers to column
4, lines 2-12 in this regard. Answer, page 4.
The examiner states that Jewell only excludes high α-
cellulose pulps, not the lower grades of pulp that contain less
α-cellulose. Answer, page 4.
The examiner states that further evidence that Jewell
includes lignocellulosic material is the statement made in
column 4 at lines 18-26, where Jewell states the following:
To the present inventors’ knowledge the lower
α-cellulose pulps or other cellulose having a high
content of hemicellulose have never before been
treated with TEMPO or other cyclic nitroxide
compounds to produce a stable carboxylated fiber.
