Freedom of Speech and Injunctions in Intellectual Property Cases
Preliminary injunctions against libel, obscenity, and other kinds of speechare generally considered unconstitutional prior restraints. Never mind thata libel may inflict truly irreparable harm on you: The most you can hopefor is damages, or perhaps a permanent injunction after final adjudication-- not preliminary relief.And yet in copyright and other intellectual property cases, preliminaryinjunctions are routine. We argue that the prior restraint doctrine hassomething to say about that, too. Though copyright law (like libel andobscenity law), is a constitutionally permissible speech restriction, the"First Amendment Due Process" rule against prior restraints applies even tosuch permissible restrictions.We argue that preliminary injunctions in copyright cases are generallyunconstitutional; the one exception is cases where there's no controversyover substantial similarity of expression or fair use (for instance, wherethe question turns only on whether defendant had the requisite license). Wealso argue the same about right of publicity cases, trademark cases, andtrade secret cases, except possibly cases (such as many trademark cases)that involve commercial advertising. We believe this conclusion is dictatedby the Court's prior restraint doctrine, and also makes good FirstAmendment policy sense.
