Qualcomm has told a federal court in San Diego that Apple is $7 billion behind in its royalty patents to the firm for technology which uses Qualcomm licenses.
Apple, which has been locked in a battle with Qualcomm for close to two years, has disputed the amount that it owes. It also claims that Qualcomm is trying to force it to pay for certain patents twice over: once for the use of Qualcomm’s chips in iPhones and once for patent royalties.
