have fairly suggested, to one of ordinary skill in the art,
dilution by a large amount such that the concentrate is used in
an amount such as about 0.1 to about 5% by weight of the dilute
aqueous treatment composition. The components are all
toxicologically acceptable, food grade components (col. 3,
lines 28-30; col. 6, lines 56-61). Thus, Murch ‘678 would have
fairly suggested, to one of ordinary skill in the art, the
compositions claimed in the appellants’ claims 12 and 19.
Claims 13 and 14: The composition can include about 0.1 wt%
to about 15 wt% of C8 to C18 fatty acid soap (col. 2, line 60;
col. 7, lines 14-41), and a sequestrant which can be sodium
and/or potassium ethylenediaminetetraacetate5 and can be present
in an amount of about 0.2 to about 4 wt% (col. 3, lines 44-49;
col. 8, lines 56-60). The exemplified viscosity is as low
as 2 cp (col. 9, lines 23-25). The buffer can be potassium
carbonate or sodium bicarbonate to provide a pH of preferably not
greater than about 12.5 (col. 9, lines 1-18 and 34-37).
Claims 15-17 and 21: One of ordinary skill in the art would
have desired to use impure water in the Murch ‘678 composition
5 The appellants’ sequestrants include sodium and/or potassium
ethylenediaminetetraacetate (specification, page 8).
