Appeal No. 2000-0018
Application No. 08/860,941
in view of Kasturi, Chapple and Svendsen
The appellants’ claim 6, which depends from claim 1,
recites that the amylase enzyme has been modified such that
its oxidative stability is enhanced.
Svendsen discloses a mutant "-amylase which exhibits
improved stability in the presence of oxidizing agents and is
well suited as a detergent additive (abstract; page 1,
lines 15-20). This disclosure would have fairly suggested, to
one of ordinary skill in the art, using this mutant "-amylase
in the detergent composition of Watson or Kasturi to obtain
the benefit of improved oxidative stability. Thus, the
composition recited in the appellants’ claim 6 would have been
prima facie obvious to one of ordinary skill in the art over
the combined teachings of Watson, Kasturi, Chapple and
Svendsen, and also over the combined teachings of Kasturi and
Svendsen.
The appellants merely argue that Svendsen does not remedy
the deficiencies in Watson, Kasturi and Chapple with respect
to the composition recited in claim 1 (brief, page 11). This
argument is not persuasive for the reasons given above
