Judge sides with Taser in patent lawsuit

Bloomberg Business Week


A federal judge in Arizona has ruled in favor of Taser International Inc. in a patent lawsuit that pit the maker of electric-shock devices against a rival company.

U.S. District Court Judge Mary H. Murguia entered a final judgment Monday against Stinger Systems Inc., concluding the company violated Taser's patent on the dual-mode, "shaped pulse" technology in its electronic control device products.

The court found that Stinger's flyback quantum technology in its Stinger S-200 electronic control device infringes on Taser's patent.

The judge ordered Stinger not to make, sell or import the S-200 in the U.S. until Feb. 11, 2023, when the Taser patent expires.

Stinger has already stopped selling the S-200 ECD. The company is in the process of being liquidated.

Taser shares added a penny to $3.65 in afternoon trading, and Stinger fell by the same amount, to 5 cents.
