Capitol Records, LLC v. ReDigi Inc.
934 F. Supp. 2d 640 (S.D.N.Y. 2013)
After losing this case, ReDigi's CEO pledged to attempt to build "ReDigi 2.0". As of 2015, however, the new service has not been made available to the public.
In 2012, the European Court of Justice ruled that the first sale doctrine applies to digital goods, and that consumers have a right to resell. However, in 2014 a German court ruled that this ECJ ruling does not apply to games on Valve's Steam gaming platform, and so the impact of the ruling appears to be quite limited.
