Preliminary injunctions are orders to stop a party from doing something prior to the trial on the merits (i.e., stop selling a trademarked product or patented item). This must only be granted considering all the evidence in the light most favorable to the non-moving party.
The movant must establish: (1) a substantial likelihood of success on the merits of the underlying case; (2) the movant will suffer irreparable harm in the absence of an injunction; (3) the harm suffered by the movant in the absence of an injunction would exceed the harm suffered by the opposing party if the injunction issued; and (4) an injunction would not disserve the public interest.
