(column 6, lines 17-20), with the glyphs being of uniform size
(Figure 3), and with the rotation determining the bit value
(Figure 3 and column 6, lines 41-52). However, further
investigation is required as to whether Bloomberg II can be
considered to disclose "a plurality of predetermined,
discriminable graphical characteristics," with a first being
glyph rotation and a second being grayscale, particularly in
light of column 5, lines 29-34, which states:
Although the following description focuses on
applications in which the scanner 25 is a black-and-
white scanner for converting the pixels of the
scanned-in image into single bit digital values
(i.e., "1" or "0"), it will be understood that it
could be a gray-scale scanner for converting the
pixels into multi-bit values.
The examiner should also note the suggestion in Sugita to
superimpose multiple types of information to record a large
amount of information (page 5 of the translation), and to make
the pieces of information independently readable such as by
using inks of different wavelengths (page 6 of the
translation).
