What are the elements of a motion seeking a preliminary injunction?

The party seeking an injunction bears the burden of proving these elements. Klein v. City of San Clemente , 584 F.3d 1196, 1201 (9th Cir. 2009) ; see also Caribbean Marine Servs. Co. v. Baldrige , 844 F.2d 668, 674 (9th Cir. 1988) (citation omitted) ("A plaintiff must do more than merely allege imminent harm sufficient to establish standing; a plaintiff must demonstrate immediate threatened injury as a prerequisite to preliminary injunctive relief."). Finally, an injunction is "an extraordinary remedy that may only be awarded upon a clear showing that the plaintiff is entitled to such relief." Winter , 555 U.S. at 22, 129 S.Ct. 365.
