As explained in my Perspectives paper, the Second Circuit went off course in Sagan by improperly applying the "volitional conduct" requirement for direct infringement liability. The lower court wrote that "direct liability attaches only to 'the person who actually presses the button.'" But that is at odds with a copyright owner's "exclusive rights to do and to authorize" under Section 106 of the Copyright Act. As the Supreme Court observed, in Sony Corp. of America v. Universal City Studios, Inc. (1984), "an infringer is not merely one who uses a work without authorization by the copyright owner, but also one who authorizes the use of a copyrighted work without actual authority from the copyright owner."
By refusing to hear the case, the court lets stand the Sixth Circuit's decision that unduly narrows the traditional understanding direct infringement and that conflicts with decisions in at least other circuits. For instance, in Society of the Holy Transfiguration Monastery, Inc. v. Gregory (2012), the First Circuit emphasized that an infringer includes "one who authorizes the use of the copyright work without actual authority from the copyright owner" – quoting Sony. And in Lewis Galoob Toys, Inc. v. Nintendo of America, Inc. (1992), the Ninth Circuit recognized that "infringement by authorization is a form of direct infringement."
For now, it is to be hoped that other lower courts will decline to follow the Sixth Circuit's misapplication of the volitional conduct requirement and unduly narrow definition of direct infringement that undermines the ability of copyright owners to enforce their exclusive rights.
