WILMINGTON, Del. - A Delaware federal judge on Sept. 27 held that a provider of virtual currency for social network games had sufficiently pleaded its claims of monopolization, tying and tortious interference against Facebook Inc., denying the social network's motion to dismiss (Kickflip Inc. v. Facebook Inc., No. 1:12-cv-01369, D. Del.; 2013 U.S. Dist. LEXIS 138733).
