Cox Communications, Inc. v. Sony Music Entertainment · ¶36

These two forms of contributory infringement track patent law. See Grokster, 545 U. S., at 942 (Ginsburg, J., concurring). Under 35 U. S. C. § 271(b), “[w]hoever actively induces infringement of a patent shall be liable as an infringer.” Such liability requires that the party express “an affrmative intent that the product be used to infringe.” Grokster, 545 U. S., at 936. Under § 271(c), a party is liable when it sells a product used for infringement “knowing the same to be especially made or especially adapted for use in an infringement of such patent.”
