4990" ethylene acrylic acid copolymer solution, described as a
20 percent solids solution, and including 1.74 percent of a
surfactant (OT-S Dioctyl Sodium Sulfosuccinate) (page 30, line
32 through page 31, line 15). Other proprietary products
tested as the binder are described as SYNTHEMUL 40-800 and 40-
850 (page 32, lines 30 through 32). Example 10 is presented
to show that the super absorbent particles adhere better to
the fibers when the binder has "free carboxyl groups." The
example is said to prepare fibers manufactured" as explained
above in connection with example 1." (see page 39, lines 25
through 36 of the specification). The example compares the
strength of adhesion of super absorbent particles with
PRIMACOR and with SYNTHEMUL 40-504 binders. The PRIMACOR
binder is stated to have "20 percent carboxylation" while the
SYNTHEMUL 40-504 is stated to have from "1 to 3 percent
carboxylation." When passed through a hammermill, fewer
particles separated from the fibers treated with the higher
carboxyl group containing binder (page 40, lines 1 through
12). No original claim (claims 1 through 18) includes any
limitation with respect to the amount of "free carboxyl
