The Harvard University classmates of Facebook founder Mark Zuckerberg are ending the legal battle made famous by the Hollywood movie "The Social Network."
In a one-paragraph court filing, Cameron and Tyler Winklevoss said they would accept a settlement that was worth $US65 million when agreed upon in 2008.
The twins had sought to undo the settlement of $20 million cash and $45 million in stock.
The 9th US Circuit Court of Appeals ruled against the twins, saying they had been represented by a squadron of Silicon Valley lawyers and their father, a noted business professor.
The twins said they would forgo a trip to the US Supreme Court.
Their stock is now worth more than $100 million.
