Ginsburg, J., concurring
2002), id., at 396–403 (testifying that he has no knowledge of any person downloading a Prelinger film using Morpheus, Grokster, or KaZaA). Compare also Decl. of Richard Prelinger ¶ 17, id., at 147 (“[W]e welcome further redistribution of the Prelinger films … by individuals using peer-to-peer software products like Morpheus, KaZaA and Grokster.”), with Deposition of Richard Prelinger (Oct. 1, 2002), id., at 410–411 (“Q. What is your understanding of Grokster? A. I have no understanding of Grokster.… Q. Do you know whether any user of the Grokster software has made available to share any Prelinger film? A. No.”). See also Deposition of Aram Sinnreich (Sept. 25, 2002), id., at 390 (testimony about the band Wilco based on “[t]he press and industry news groups and scuttlebutt.”). These declarations do not support summary judgment in the face of evidence, proffered by MGM, of overwhelming use of Grokster’s and StreamCast’s software for infringement.[1]
- ↑ Justice Breyer finds support for summary judgment in this motley collection of declarations and in a survey conducted by an expert retained by MGM. Post, at 952–955. That survey identified 75% of the files available through Grokster as copyrighted works owned or controlled by the plaintiffs, and 15% of the files as works likely copyrighted. App. 439. As to the remaining 10% of the files, “there was not enough information to form reasonable conclusions either as to what those files even consisted of, and/or whether they were infringing or non-infringing.” Id., at 479. Even assuming, as Justice Breyer does, that the Sony Court would have absolved Sony of contributory liability solely on the basis of the use of the Betamax for authorized time-shifting, post, at 950–951, summary judgment is not inevitably appropriate here. Sony stressed that the plaintiffs there owned “well below 10%” of copyrighted television programming, 464 U.S., at 443, and found, based on trial testimony from representatives of the four major sports leagues and other individuals authorized to consent to home-recording of their copyrighted broadcasts, that a similar percentage of program copying was authorized, id., at 424. Here, the plaintiffs allegedly control copyrights for 70% or 75% of the material exchanged through the Grokster and StreamCast software, 380 F.3d 1154, 1158 (CA9 2004); App. 439, and the District Court does not appear to have relied on comparable testimony about authorized copying from copyright holders.
