Vacated and remanded. Petitioning party received a favorable disposition.
Respondent companies distribute free software that allows computer users to share electronic files through peer-to-peer networks, so called because the computers communicate directly with each other, not through central servers. Although such networks can be used to share any type of digital file, recipients of respondents’ software have mostly used them to share copyrighted music and video files without authorization. Seeking damages and an injunction, a group of movie studios and other copyright holders (hereinafter MGM) sued respondents for their users’ copyright infringements, alleging that respondents knowingly and intentionally distributed their software to enable users to infringe copyrighted works in violation of the Copyright Act.
