In an odd turn of events, Immersion, the company that sued both Sony and Microsoft for copyright infringement over the rumble function in their controllers, is being sued by Microsoft for violating their settlement, which had Microsoft paying Immersion $26 million for licensing right (settling the rumble dispute) and a stake in the company. A lesser known part of the contract would have Immersion paying an undisclosed amount to Microsoft (“based on certain business and IP licensing arrangements”)- something Immersion never did. So, Microsoft filed a suit against Immersion- backlash, much?
