Irvine Firm Goes On Patent Offensive

Irvine-based Uniloc USA, a firm which develops anti-fraud technology based on physical device recognition, said this morning that it has filed a patent infringement suit against Sony America, McAfee, Activision, Quark, Aspyr Media, and Borland Software. According to the firm, it has filed suit in the United States District Court for the Eastern District of Texas, Tyler Division over unauthorized use of its anti-piracy product activation method and system. Uniloc said that it has also been in a legal battle with Microsoft over similar misuse of its patents, and is currently in appeals over an April 2009 win over Microsoft, which awarded $388M in damages to the firm.
