In the past, Apple used Qualcomm’s modem chips in its flagship iPhone models to help them connect to wireless data networks. But early last year, Apple sued Qualcomm in federal court in San Diego, alleging that the chip company’s practice of taking a cut of the selling price of phones as a patent license fee was illegal.
Qualcomm denied the claims and has alleged that Apple owes it $7 billion in unpaid royalties.
The case is to go to trial early next year and has spawned related legal actions in other courts around the world. Qualcomm CEO Steve Mollenkopf has said the company expects an out-of-court settlement.
