Qualcomm urges U.S. regulators to reverse course and ban some iPhones

Qualcomm Inc is urging U.S. trade regulators to reverse a judge’s ruling and ban the import of some Apple Inc iPhones in a long-running patent fight between the two companies.

Qualcomm is seeking the ban in hopes of dealing Apple a blow before the two begin a major trial in mid-April in San Diego over Qualcomm’s patent licensing practices. Qualcomm has sought to apply pressure to Apple with smaller legal challenges ahead of that trial and has won partial iPhone sales bans in China and Germany against Apple, forcing the iPhone maker to ship only phones with Qualcomm chips to some markets.
