"Defendant’s publication and sale of [TWDG would] infringe the plaintiff’s copyright interests as protected under the copyright laws.” Id. Houghton Mifflin appealed. At oral argument, we issued an order vacating the injunction on the grounds that it was an unconstitutional prior restraint. SunTrust Bank v. Houghton Mifflin Co., 252 F. 3d 1165 (11th Cir. 2001). We now vacate that order and issue this more comprehensive opinion. B. Standard of Review “We review the district court’s grant of a preliminary injunction for abuse of discretion.” Warren Pub., Inc. v. Microdos Data Corp., 115 F.3d 1509, 1516 (11th Cir. 1997) (en banc). We review decisions of law de novo and findings of fact for clear error. Mitek Holdings, Inc. v. Arce Eng’g Co., Inc., 89 F.3d 1548, 1554 (11th Cir. 1996). II. DISCUSSION Our primary focus at this stage of the case is on the appropriateness of the injunctive relief granted by the district court. In our analysis, we must evaluate the merits of SunTrust’s copyright infringement claim, including Houghton Mifflin’s affirmative defense of fair use. As we assess the fair-use defense, we examine to what extent a critic may use a work to communicate her criticism of the work without infringing the copyright in that work."
