U.S. judge rules Qualcomm owes Apple nearly $1 billion rebate payment

A U.S. federal judge has issued a preliminary ruling that Qualcomm Inc owes Apple Inc nearly $1 billion in patent royalty rebate payments, though the decision is unlikely to result in Qualcomm writing a check to Apple because of other developments in the dispute.

Judge Gonzalo Curiel of the U.S. District Court for the Southern District of California on Thursday ruled that Qualcomm, the world’s biggest supplier of mobile phone chips, was obligated to pay nearly $1 billion in rebate payments to Apple, which for years used Qualcomm’s modem chips to connect iPhones to wireless data networks.
