Appeal No. 1997-2188
Application 08/137,440
appellants in their specification at page 8, line 24 through
page 10, line 18. The compositions do not exclude any other
materials, including materials disclosed but not claimed and
materials neither disclosed nor even contemplated.
Appellants' method claims are directed to two separate
embodiments: one where memory dysfunction characterized by
decreased cholinergic function is treated by administering the
compounds of claim 1 to a mammal in an amount effective to
inhibit AChE; and, a second where memory dysfunction
characterized by decreased cholinergic function is treated
with 6-O-demethylgalanthamine, a known AChE inhibiting
compound, by administering to a mammal in an amount sufficient
to inhibit AChE the compound of Claim 4. Thus, both methods
are limited to treating memory dysfunction characterized by
decreased cholinergic function.
The first method requires administering to a mammal with
memory dysfunction characterized by decreased cholinergic
function an amount of the compound of claim 1 sufficient to
inhibit the formation in the mammal of the enzyme AchE. As a
"comprising" claim the first method does not exclude any other
step or ingredient, including steps or ingredients disclosed
but not claimed and even steps or ingredients neither
