Qualcomm (NSDQ: QCOM) has violated a court order to stop using chipsets that infringe on Broadcom patents, a federal judge ruled on Thursday. There is “clear and convincing evidence,” that showed Qualcomm is in contempt of his late 2007 ruling, U.S. District Judge James Selna said, the San Diego Union-Tribune reports. Selna followed up by ordering Qualcomm to stop providing support services for some 3G cellphones and to pay Broadcom all profits earned from its QChat walkie-talkie service, which is offered by Sprint (NYSE: S). A court document dug up by Reuters indicates Qualcomm received more than $93 million in QChat payments from Sprint since the injunction ruling. Thursday’s ruling gave Qualcomm 30 days to calculate profits from its QChat software and to make a payment. Alex Rogers, Qualcomm’s SVP and legal counsel, told the San Diego Union-Tribune that Qualcomm is already using a new version of its QChat software and mobile phones that were designed around the Broadcom patents.
