Application No. 07/871,401
the art, the teachings regarding sulphite pulps would not be
applicable to sulphate pulps. The examiner acknowledges the
Renard Declaration but only cites the above noted teachings of
Granum to rebut this Declaration (Answer, page 8).
Granum also teaches that the best bleaching sequences
differ even between different sulphite processes. The general
process of Granum involved the calcium base acid sulphite
process where the best bleaching sequence was D/C ZEH (page J
1
26, middle column). Granum teaches that the “results from
bleaching of magnesium sulphite pulps are somewhat different”
and the best bleaching sequence for this pulp was D/CEH (page
J 28, left column).
Considering the totality of the record, we determine that
the examiner has failed to show any suggestion for combining
the references as proposed, either in the references
themselves or in the knowledge generally available to the
artisan. Jones, supra. Therefore no prima facie case of
obviousness has been established and the rejection of claims
1-3 and 5-8 under § 103 is reversed.
B. The Rejection of Claim 4
