Motorola Wants U.S. to Ban Sale of BlackBerry Devices

Motorola has asked U.S. regulators to bar Research In Motion from the U.S. sale of its products, accusing the BlackBerry maker of infringing on five Motorola technology patents. Motorola, which has been losing market share to Canada's RIM for years, said most of RIM's products infringe on at least one of the patents, which cover technology for Wi-Fi, application management, user interface and power management.
