formulating a printing ink from a single dye or a mixture of
at least two dyes so that the formulation results in the
greatest degree of metamerism between the formulated printing
ink and a reference ink on the basis of two defined types of
illumination (Id. at page 3). Independent claim 5 is
illustrative of the subject matter on appeal and is reproduced
below:
5. A method of producing a colored printed article which
is clearly visually different from color copies produced
therefrom, which method comprises the steps of
a) formulating a printing ink from a single dye or a
mixture of at least two dyes so that the formulation results
in the greatest possible degree of metamerism between the
formulated printing ink and a reference ink on the basis of
two defined types of illumination, which reference ink is of a
type typically used in color copiers; and
b) printing at least one characteristic area of said
article with said formulated printing ink.
Claims 2 through 9 stand rejected under 35 U.S.C. § 112,
second paragraph, “as being indefinite and incomplete.”
