Ubisoft has filed a lawsuit against Optical Experts Manufacturing, the North Carolina-based company it had used to makes copies of Assassin's Creed on PC. OEM failed to follow its own security measures and allowed an employee to take home a copy of the game, who then uploaded it on the internet six weeks before its official release. Ubisoft claims the leak was downloaded 700,000 times, costing the publisher millions of dollars, and is suing for breach of contract and negligence, asking for $10 million each.
