ITEM 8.01  OTHER EVENTS.
- ------------------------

     On February 18, 2004, CNS, Inc. (the "Company"), together with Creative
Integration & Design, Inc., sued Silver Eagle Labs, Inc. ("Silver Eagle") in the
United States District Court for the District of Minnesota for infringement of
two nasal dilator patents owned by Creative Integration & Design, Inc. and
exclusively licensed to the Company. The two patents at issue are U.S. Patent
No. 6,318,362 (the " '362 Patent") and U.S. Patent No. 3,533,503 (the " '503
Patent"). The suit seeks injunctive relief, damages, enhanced damages for
willful infringement, attorneys' fees and costs. Silver Eagle has counterclaimed
for a declaration that the '362 Patent and '503 Patent are invalid and not
infringed and asks for its attorneys' fees and costs.

     On November 24, 2004, the Company announced that the U.S. Patent and
Trademark Office will reexamine the '362 Patent and the '503 Patent. In response
to this action by the U.S. Patent and Trademark Office, on November 29, 2004,
the Court issued an order staying the Company's suit against Silver Eagle
pending the reexamination. The Company believes that when the '362 and '503
Patents emerge from reexamination, the Company will maintain significant patent
protection under those patents and will recommence enforcement of those patents
in the litigation described above. The Company maintains patent protection for
its nasal dilator products under other United States and foreign patents and
will continue to vigorously enforce all of its intellectual property.
