Apple owes Qualcomm $7 billion in royalty payments says chip designer
40

Apple and Qualcomm are entangled in a number of lawsuits over patent royalties and other matters. As a result of the animosity between the two companies, Apple stopped using Qualcomm's modem chips on the iPhone, turning to Intel's chips instead. That led to another recently filed lawsuit when Qualcomm accused Apple of turning over the latter's modem chipset "secrets" to Intel.
Qualcomm revealed the $7 billion figure in federal court in San Diego. Apple's Cupertino headquarters is over 700 miles from the city, which gives Qualcomm a major "home court advantage." The chip designer is based in San Diego.
