When can a character be protected by copyright? Over the years, it has been an interesting question for courts to address. In early cases involving Superman, the court found the character was sufficiently different from stock Hercules-type characters to warrant copyright protection. A more recent example was addressed in Gaiman v. McFarlane (briefly discussed here); the Seventh Circuit looked closely at the Cogliostro character to determine if the character was more than a stock wizened, wise wino.
In 2015, the Ninth Circuit Court of Appeals revisited the question of what characters can be protected by copyright in DC Comics v. Towle. At issue was whether the Batmobile could be considered a character entitled to copyright protection.
Mark Towle made and sold replicas of the Batmobiles from the Adam West TV show and the Michael Keaton movie. They were near-exact replicas, and he also advertised the cars as the Batmobile and used bat motifs throughout the vehicles. In 2011, DC brought a lawsuit against him alleging copyright infringement, trademark infringement, and other causes of action. The district court found Towle’s actions in reproducing the Batmobile constituted copyright infringement.
On appeal, the Ninth Circuit upheld the lower court’s decision. The central part of the Court’s decision revolved around how “‘sufficiently distinctive’” a character must be in order to receive copyright protection and whether the Batmobile met the requirement. In analyzing the Batmobile, the court found (1) “it has ‘physical as well as conceptual qualities,’ and is thus not a mere literary character[,]” (2) it is “recognizable as the same character whenever it appears” because it is almost always high-tech, has bat-like features, and has consistent features, and character traits, and (3) it’s “‘especially distinctive’ and contains unique elements of expression” because of its sidekick-status, character traits, physical characteristics, and recognizable name. Because the Batmobile satisfied the court’s three-part test, it ruled the Batmobile to be an “‘especially distinctive’ character entitled to copyright protection.” Because the Batmobile is entitled to copyright protection, Towle’s faithful reproductions of the Batmobile constituted copyright infringement.
The court’s decision further paves the way for copyright protection to extend to non-traditional “characters” in comic books so long as they meet the criteria set forth by the court. It’s good to keep this case in mind as you create your work and realize that copyright protection can apply to inanimate, side “characters” in addition to your main creations.
