TASER International Wins Patent Infringement Summary Judgment Against Stinger
Systems, Inc.

SCOTTSDALE, Ariz., April 2, 2010 (GLOBE NEWSWIRE) — TASER International, Inc.
(Nasdaq:TASR) today announced that on March 31, 2010, the United States District
Court for the District of Arizona entered an order for TASER International in
the patent infringement lawsuit filed against Stinger Systems entitled TASER
International, Inc. v. Stinger Systems, Inc. granting TASER’s motion for summary
judgment against Stinger for literal patent infringement of TASER’s U.S. Patent
6,999,295 (“295 Patent”).

The patent infringement claim against Stinger’s S-200 is based on TASER’s patent
on the dual mode “shaped pulse” technology found in the TASER(R) X26(TM),
X3(TM), Shockwave and C2(TM) products. The Court’s ruling found that the
“Flyback Quantum Technology” found in the Stinger S-200 literally infringes
TASER’s ’295 Patent. The Court stated that, “A party is liable for inducing
infringement on a method claim ‘if it sells infringing devices to customers who
use them in a way that directly infringes this method claim.’” The Court
concluded, “Accordingly, TASER has demonstrated that the [Stinger] S-200
embodies every element of claims 2 and 40 and summary judgment concerning
infringement of ’295 patent is warranted.” In a related ruling, the Court
granted Stinger summary judgment on its motion that claim 3 of TASER’s U.S.
Patent 7,102,870 is invalid as obvious.

TASER also filed a complaint in February 2009 in the United States District
Court for the District of Nevada against James F. McNulty, Jr., Robert Gruder,
and Stinger Systems, Inc. alleging securities fraud under 15 U.S.C. §
78j(b), trade libel/defamation, unfair competition in violation of the Lanham
Act, 15 U.S.C. § 1125(a), abuse of process, and deceptive trade practices.
Defendants brought a motion to dismiss this complaint and on March 25, 2010 the
Court denied this motion on all claims except the securities fraud claim.

“We believe the Court’s ruling in this patent infringement lawsuit against
Stinger is a vindication of the important patent rights of TASER International
and a rebuke to competitors who try to copy our protected intellectual
property,” said Doug Klint, President and General Counsel of TASER
International.

In addition, the company announced that four (4) product liability lawsuits
filed against TASER were dismissed in First Quarter 2010.
