A federal judge has rejected the “novel argument” Kirkland & Ellis made in an attempt to dismiss patent infringement claims that SharkNinja, a major industry competitor, brought against its client, Dyson.

Counsel with Wilmer Cutler Pickering Hale and Dorr and Gibson, Dunn & Crutcher filed the lawsuit on behalf of the global appliance company in U.S. District Court for the District of Massachusetts. While SharkNinja sought a declaratory judgment that its FlexStyle haircare product does not infringe on Dyson’s competing AirWrap product, the plaintiff filed a second amended complaint accusing Dyson of issuing up to nine product lines that all infringed on eight vacuum patents belonging to SharkNinja’s exclusive partner, Omachron Alpha.
