Application No. 07/871,401
omitted or eliminated. The examiner has only alleged that the
brightness of the pulp would be affected (Answer, page 5).
Furthermore, the examiner has not presented any reasoning or
evidence as to why one of ordinary skill in this art would
have been motivated to eliminate the H stage. It should be
noted that 10 of the 11 bleaching sequences taught by Granum
on page J 27 include the H stage.
For the foregoing reasons, we determine that the examiner
has failed to establish a prima facie case of obviousness.
Therefore the rejection of claim 7 under § 103 as unpatentable
over Granum is reversed.
D. The Rejection of Claim 8
The cellulosic kraft pulp of claim 8 is set forth in
product-by-process terminology, with the requirement that the
pulp is “essentially free” of 2,3,7,8 tetrachlorodibenzodioxin
or 2,3,7,8 tetrachlorodibenzofuran, has a total organic
chloride content (TOCL) of less than about 200 ppm, based on
pulp, and a total adsorbed organic halogen content (AOX) of
less than about 2 kg/ton, based on pulp.
