At the crux of the court's decision was "whether the statutory phrases 'actual knowledge that the material or an activity using the material on the system or network is infringing,' and 'facts or circumstances from which infringing activity is apparent'" in 17 U.S.C. ยง 512(c)(1)(A)(i) and (ii) mean "a general awareness that there are infringements" as argued by Viacom, or instead mean "actual or constructive knowledge of specific and identifiable infringements of individual items," as argued by YouTube. The court agreed with YouTube's interpretation, ruling it was supported by both the DMCA's legislative history and recent case law.
Both sides have submitted their appellate briefs, and the Second Circuit has received 28 briefs filed by amici curiae. Oral argument will likely be scheduled between late August and late September.
