Lawyer for Facebook Accuser Files Defamation Complaint

The small-town lawyer who sued Facebook Inc. over his client’s claim to own the social network has filed his own defamation suit against the company and co-founder Mark Zuckerberg. Attorney Paul Argentieri sued in San Francisco claiming Facebook falsely accused him of fraud in a public statement about his representation of Paul Ceglia, the western New York man who fled to avoid criminal charges he faked the 2003 contract and e-mails on which he based his claim.
