SharkNinja

The company has its origins through Euro-Pro Operating LLC in 1994, when Mark Rosenzweig of Montreal, whose family had run the business for generations prior to its incorporation, developed steam cleaners and upright vacuums. In 2003, Rosenzweig moved the headquarters from Montreal to Needham, Massachusetts.[5][6] The company changed its name in 2015 to capitalize on its brand names' prominence and popularity.[7] In 2013 the company registered an entity in the United Kingdom and began selling products under the Shark brand.[8]

In 2017, the company was acquired by CDH Private Equity from Weston Presidio and American Capital.[3] It was then structured as a subsidiary of JS Global, a Chinese maker of appliances. SharkNinja accounted for almost half of JS Global's revenue in 2018.[9] As of 2020, it has offices in ten countries[10] and holds over 550 patents, used in over 150 products.[11]

In 2014, Dyson sued SharkNinja for infringement of three vacuum technology patents, but after four years courts ruled the patents had not been infringed.[12]

In 2019, SharkNinja sued the manufacturer of the Emeril Lagasse Pressure AirFryer for patent infringement, but the case was dismissed.[12]

In January 2021, iRobot sued SharkNinja for false advertising and patent infringement related to robotic vacuum cleaners. As of March 2023, the case is still pending before the United States International Trade Commission.[12]
