If this guy's claims are legitimate, does he own 85% of all of Facebook, or 85% of Zuckerberg's share of Facebook? Presumably he would have been diluted in subsequent funding rounds, etc?

What portion of Facebook does Zuckerberg still own?

IANAL, but perhaps it could be argued that MZs continued work after the "online yearbook" site launched in 02/2004 constituted sweat-equity and thus diluted Ceglia's shares?

Anyway, if Ceglia and his lawyers have half a mind, they're after a tiny (compared to 84%) settlement.

Wikipedia says 24%.
