Appeal No. 2003-0234
Application No. 09/446,202
Claims 8 and 9: Murch ‘678 teaches that the composition can
contain typically up to 0.2 wt% of salts of dodecylbenzene
sulfonate, a base stable anionic surfactant (col. 8, lines 48-
52). 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). The aqueous carrier can be water
or water/ethanol (col. 3, lines 18-21). Hence, Murch ‘678 would
have fairly suggested, to one of ordinary skill in the art, the
compositions claimed in the appellants’ claims 8 and 9.
Claims 10 and 11: The composition includes about 0.01 to
about 15 wt% of a C8 to C18 soap (col. 2, line 60; col. 7,
lines 14-41), and the exemplified viscosity is as low as 2 cp
(col. 9, lines 23-25).
Claims 12 and 19: Murch ‘678 discloses a food-treating
composition which can contain about 0.1 to about 4 wt% of a
toxicologically acceptable nonionic surfactant (col. 2, lines 61-
65), and can contain a buffer to provide a pH of no more than
about 12.5 (col. 9, lines 1-37).4 The composition can be a
concentrate (col. 4, lines 10-13), even to the point of being a
non-aqueous liquid or solid (col. 5, lines 10-11), which would
4 The orthophosphate in element (b) need not be present.
