the greeting card being removed from contact with the lower writeable
surface (Specification 6:7-19). Appellants’ UV LED illuminates the indicia
on the greeting card visible only under UV light (Specification 3-4). As
illustrated in Figs. 1 and 5B, this might encompass the entire width of the
card or substrate, indicating Appellants’ characterization of UV LEDs as
capable of relatively broad angle illumination.
FF3. Solomon discloses a writing system, applicable to all forms of writing
and drawing, and to diaries, journals, stationery, and games in particular,
with the intention of guarding the handwritten or drawn content using a
combination of special ink visible to the human eye only upon excitation by
ultraviolet light (ultraviolet ink), paper, and ultraviolet light (Solomon,

[0021]).
FF5. Solomon discloses an ultraviolet light bulb 11, which bulb is
