Facebook has called the lawsuit "frivolous."
In last night's interview, however, Zuckerberg did not say he absolutely did not sign any contract, and steered clear of completely rebutting the claim. "We're quite sure that we did not sign a contract that says they have any right to ownership over Facebook," he said.
Earlier this week, a Facebook lawyer was widely quoted in online reports saying she was "unsure" if Zuckerberg had signed the contract.
However, in an e-mail to Computerworld on Wednesday, Facebook spokesman Andrew Noyes said the attorney, Lisa Simpson, was misquoted and had only been trying to say that they've never seen the original document.
"We have serious questions about the authenticity of the document and, assuming an original exists, we look forward to expressing our opinion about it once we see it," Noyes added.
In the interview with Zuckerberg last night, Sawyer also brought up the upcoming movie about the evolution of Facebook, The Social Network. Due out this October, the film doesn't paint Zuckerberg in the best light, focusing on issues of who actually was involved in creating the Web site.
Zuckerberg said he would not go see the movie.
Zuckerberg said in an excerpt from the interview posted at ABCNew.com, "I mean, we can't be focused when people try to say things that aren't true. I really believe that people get remembered for what they build."
"...Right, people don't care about what someone says about you in a movie -- or even what you say, right? They care about what you build. And if you can make something that makes people's life better, then that's something that's really good," he said.
