Tyler and Cameron Winklevoss, the twin brothers accused Mark Zuckerberg, 26, of stealing their idea for a social networking site.
The 29-year-old identical twins, who were cruelly labelled the “Winklevii” in this year’s partly fictional account of Facebook’s founding, The Social Network, allege they were misled over the true value of the site when they launched legal proceedings in 2006.
Facebook responded to the suit with legal papers of its own and accused the brothers of “suffering a bout of settler’s remorse”. In documents filed at the United States District Court for the Northern District of California, Facebook said that the brothers had calculated the value of the company using a press release issued by Facebook several months before the settlement – and that it was under no obligation to submit alternative figures.
The bitter dispute began in 2003 while the twins and Zuckerberg were students at Harvard University. The twins allege they, along with fellow student Divya Narendra, had a verbal agreement with Mr Zuckerberg to build the programming for their Harvard Connections site. Months later, Mr Zuckerberg created the rival site that eventually became Facebook, which now boasts over 500 million users. Mr Narendra, who also took a settlement payout in 2008, is not a co-claimant in the Winklevoss twins’ most recent claim.
