Apple, Qualcomm battle over possible ban on some U.S. iPhone imports

The San Diego chipmaker filed a complaint against Apple nearly a year ago, asking the commission to ban the import of iPhones containing rival chipmaker Intel Corp’s (INTC.O) so-called modem chips, which help mobile phones connect to wireless data networks. At a trial in Washington that started on Friday, the ITC staff said Apple violated one of Qualcomm’s patents around battery-saving technology.
