Supreme Court Docket

Metro-Goldwyn-Mayer Studios Inc., et al.
Grokster, Ltd., et al.
545 U.S. 913 (2005)
Question Presented:

Whether the Ninth Circuit erred in concluding, contrary to long-established principles of secondary liability in copyright law (and in acknowledged conflict with the Seventh Circuit), that the Internet-based "file sharing" services Grokster and StreamCast should be immunized from copyright liability for the millions of daily acts of copyright infringement that occur on their services and that constitute at least 90% of the total use of the services.


Were companies that distributed file-sharing software, and encouraged and profited from direct copyright infringement using such software, liable for the infringement?
