Does Paul Ceglia Own 83 Percent of Facebook?

(CANVAS STAFF REPORTS) - Almost everyone has heard of Facebook founder and CEO, Mark Zuckerberg. And he'll be even more famous after the new Hollywood movie "The Social Network," starring Justin Timberlake, hits movie theaters on October 1.

But a New York man is coming out of the woodwork, trying to stake a claim to a large chunk of the social media site worth billions.

Bloomberg.com reported that Paul Ceglia is suing Zuckerberg for 84 percent of Facebook Inc.

According to his attorney, Ceglia has a copy of a $3,000 cashier's check in his possession that could potentially change his life forever. Even though the lawsuit was officially launched on June 30, this week the check was made public, appearing on The Wellsville Daily Reporter website.

The case is set to go to federal court in Buffalo, N.Y, with Ceglia claiming that Zuckerberg offered a 50 percent stake in a new company he was launching in 2003, called "The Face Book," if Ceglia invested $1,000.

Ceglia said Zuckerberg and he had a work-for-hire contract in which the computer genius was set to do computer coding for him, and the alleged investor was offered an additional 34 percent if there were delays in the work being complete.

Based on estimates of the company's value, the stake would be worth about $21 billion, according to Business Week .

Ceglia said he only realized he could become a billionaire after he was arrested by state troopers for fraud last year, according to Business Week .

After searching through his old papers in his house in western New York to find assets to pay back his clients to whom he failed to make wood pellet deliveries, he said he found the contract signed in 2003 by Zuckerberg.

Meanwhile, BusinessInsider.com raised questions about Ceglia's check claim that if answered could show that the case is legitimate: Where is the original contract? Why wait seven years to file the suit? And where's the money trail?
