The lawsuit caps a bad week for the small company, which lost the rights to its Aimster.comdomain name to AOL Time Warner in an arbitration panel Monday.
The Recording Industry Association of America, which has previously suedfile-trading companies Napster and Scour on similar issues, sent a warningletter to Aimster several months ago, noting that the company's activitieswere similar enough to Napster's that it was likely in violation of the law. But unlike other file-swappingcompanies that received similar letters, Aimster has declined to filtersongs or monitor its members' activities.
The Motion Picture Association of America was expected to file its own separate suit later.
"Aimster is Napster all over again," Cary Sherman, general counsel for the RIAA, said in a statement. "Beneath the added bells and whistles lies the same service that Napster provides."
In an unrelated action, record companies sued online radio companyLaunch Media, alleging it was violating copyright laws by allowingWebcast listeners too much control over what and when theywanted to hear specific songs or bands.
Like Napster or any of its other rivals, Aimster allows individuals withcomputers connected to the Internet to trade files that are stored on theirhard drives.
The company started with a different twist on the idea of file sharing,allowing people to create "buddy lists" such as those on AOL InstantMessenger and to open their computers just to this select group of people.By creating these small, private networks, Aimster said it was preservingpeople from outside scrutiny.
But for the last month or two, the company has also offered a moresprawling, Napster-like service, in which people can search for music,video or software across a network comprising tens of thousands of people.New Aimster users were automatically added into this network unless theyconfigured their software specifically for the smaller buddy list trading.
Aimster CEO Johnny Deep has been among the most vocal bomb-throwers inthe file-trading community over the last few months. When Napster beganusing filters, Aimster released a software program that turned filenames into Pig Latin, serving as a temporary way around the blockingmechanism. It later took this down at Napster's request.
More recently, the company went to court, asking for a judgment thatits "private virtual networks" were legal. Unlike Napster, the company andthe people who use its software do more than trading music files, andbreaking into these personal private networks to look for copyrighted fileswould itself be a violation of copyright law, company attorneys contended.A judge has yet to rule on that motion.
The record industry lawsuit against Aimster will provide a high-profilevenue for testing this unconventional legal interpretation. The suit wasfiled in New York federal court.
Deep is personally named in the suit as a representative of the Aimster service--as are BuddyUSA and AbovePeer, corporate entities that own the Aimster software and file-swapping service, respectively.
Deep declined to comment specifically on the suit, saying the company hadn't yet seen it. But "we already have a motion that asks a federal court for guidance in deciding how to balance rights to privacy and free speech with protection of copyright," he said.
In an interview with CNET News.com earlier this week, Deep said that he personally was willing to fight a full RIAA lawsuit but that such action was "a question for everybody involved" with the company.
