Microsoft successfully banned Motorola Smartphones from the market, now Motorola is fighting back. Motorola is claiming infringement of their patents; some of their technology used in the XBOX 360 utilizes what they've made (wireless controller; the wireless IR chip). If this falls through on Motorola's side, Microsoft will be forced to remove their products from store shelves. I'm assuming they'll have to advise on a new wireless technology in the controllers.
