Apple Filed a $1 Billion Lawsuit Against Qualcomm

Jan 20, 2017

Apple filed a $1 billion lawsuit against supplier Qualcomm on Friday, following a U.S. government lawsuit which accused the chip maker of using anti-competitive tactics to maintain its monopoly of a key semiconductor used in mobile phones.

In the lawsuit, Apple (aapl) accused Qualcomm (qcomm) of overcharging for its chips and for refusing to pay some $1 billion in promised rebates for chip purchases. Apple said in its complaint that Qualcomm withheld the rebates because of Apple's discussions with South Korea's antitrust regulator.
