Cameron and Tyler Winklevoss were classmates of Mark Zuckerberg at Harvard University. They and one other individual argued that Zuckerberg used many of
their ideas to create Facebook in 2003. They filed suit against Zuckerberg but settled. As a part of the settlement in 2008 they received $65 million in
cash and some stock in Facebook.
Subsequently however they filed suit once again alleging that Zuckerberg had deceived them about the nature of Facebook and they should have received
more. In July 2011 this suit was dismissed by a federal court judge.
