SharkNinja Sues Tristar, Emeril Claiming Foodi Patent Infringement

SharkNinja Operating LLC (SharkNinja) said it has filed a complaint against Tristar Products, Inc. and Emeril Lagasse for what SharkNinja claims is infringement of three U.S. patents related to its Ninja Foodi pressure cooker kitchen appliance that debuted September 2018.

The lawsuit was filed on Friday, October 4, in the United States District Court for the Southern District of Florida.

SharkNinja’s complaint alleges that Tristar’s Emeril Lagasse Pressure AirFryer, which came to the market after Foodi, infringes three of its United States patents: U.S. Patent No. 10,390,656; U.S. Patent No. 10,413,121; and U.S. Patent No. 10,413,122.

In the lawsuit, SharkNinja is seeking damages resulting from Tristar’s patent infringement and a court order barring the sale of the Emeril Lagasse Pressure AirFryer.

A spokesperson for Tristar said Tristar and Lagasse will “vigorously defend themselves against SharkNinja’s faulty claims.”
