EU regulators are asking Qualcomm’s competitors about its practices

EU antitrust regulators are asking Qualcomm’s rivals how the U.S. chipmaker’s business practices and the way it licenses its products affect them, as part of an investigation begun seven months ago, a document seen by Reuters showed. Qualcomm has been feeling the regulatory heat in Europe, the United States, China, Japan and South Korea in recent years as watchdogs focus on its licensing model and its power over patents. The bulk of its revenue comes from selling baseband chips, which enable phones to communicate with carrier networks, but a large portion of its profit comes from licensing patents for its CDMA cellphone technology. The European Commission told Qualcomm in October last year that it was investigating the way it sells and markets its chips, as well as rebates and financial incentives offered to customers, the company said in a regulatory filing last month. In a questionnaire sent to competitors last week, the EU competition authority asked about the impact of various Qualcomm practices such as pass-through rights where phone makers are allowed to use patents already licensed by Qualcomm.
