Apple Sues Qualcomm, Seeks $1 Billion in Rebate Payments

Apple Inc. is suing Qualcomm Inc., alleging the smartphone-chip supplier demanded onerous terms for its technology and that it sought to punish Apple for cooperating in a Korean regulatory probe into Qualcomm’s licensing practices. The suit, which Apple said it filed in federal district court in the Southern District of California, claims that Qualcomm leveraged its position as a manufacturer of a critical chip used in cellphones to seek “onerous, unreasonable and costly” terms for patents and blocked Apple’s ability to choose another supplier for chipsets.
