The National Law Journal has the full story, but you'll need a subscription. According to The Los Angeles Times, the software developer claims in his
suit that he formed the Winklevoss Chang Group partnership with the Winklevoss twins to specifically own and operate jointly the social networking site ConnectU and the peer-to-peer file-sharing site
and application i2hub.
His 50% stake in the Winklevoss Chang Group therefore entitles the developer to half of the twins' 2008 settlement with Facebook, he believes. Meanwhile, as The LA Times notes, the twins have been trying to get out of their Facebook settlement in suits of their own against the social network.
