Ginsburg, J., concurring
Justice Ginsburg, with whom The Chief Justice and Justice Kennedy join, concurring.
I concur in the Court’s decision, which vacates in full the judgment of the Court of Appeals for the Ninth Circuit, ante, at 941, and write separately to clarify why I conclude that the Court of Appeals misperceived, and hence misapplied, our holding in Sony Corp. of America v. Universal City Studios, Inc., 464 U.S. 417 (1984). There is here at least a “genuine issue as to [a] material fact,” Fed. Rule Civ. Proc. 56(c), on the liability of Grokster or StreamCast, not only for actively inducing copyright infringement, but also or alternatively, based on the distribution of their software products, for contributory copyright infringement. On neither score was summary judgment for Grokster and StreamCast warranted.
At bottom, however labeled, the question in this case is whether Grokster and StreamCast are liable for the direct infringing acts of others. Liability under our jurisprudence may be predicated on actively encouraging (or inducing) infringement through specific acts (as the Court’s opinion develops) or on distributing a product distributees use to infringe copyrights, if the product is not capable of “substantial” or “commercially significant” noninfringing uses. Sony, 464 U.S., at 442; see also 3 M. Nimmer & D. Nimmer, Nimmer on Copyright §12.04[A][2] (2005). While the two categories overlap, they capture different culpable behavior. Long coexisting, both are now codified in patent law. Compare 35 U.S.C. §271(b) (active inducement liability), with §271(c) (contributory liability for distribution of a product not “suitable for substantial noninfringing use”).
In Sony, 464 U.S. 417, the Court considered Sony’s liability for selling the Betamax video cassette recorder. It did so enlightened by a full trial record. Drawing an analogy to the staple article of commerce doctrine from patent law,
