The Recording Industry Association of America (RIAA) has prevailed in its copyright infringement lawsuit against LimeWire, one of the largest remaining commercial peer-to-peer services. The Court ruled that LimeWire was liable for copyright infringement because its users commit a “substantial amount of copyright infringement” and the company behind the software “has not taken meaningful steps to mitigate infringement.”

RIAA has alleged that at least 93 percent of LimeWire’s file sharing traffic was unauthorized copyrighted material. The RIAA is seeking up to $150,000 per violation, although the final damages have not yet been determined.

This was the first case against a file sharing software maker after the 2005 Grokster decision, in which the U.S. Supreme Court upheld lawsuits against companies that induced or encouraged file sharing.
