US chips maker Qualcomm (NASDAQ:QCOM.NASDAQ) has countersued Apple (NASDAQ:APPL.NASDAQ) claiming the company that has made its fortune on the back of Qualcomm technology now "refuses to acknowledge the well established and continuing value of those technologies".
Apple sued the supplier of the processors it uses in its iPhones in for $1 billion in January, alleging that Qualcomm had been charging royalties for "technologies they have nothing to do with."
In a suit filed in the US District Court for the Southern District of California yesterday Qualcomm said it had addressed Apple's claims and was seeking unspecified damages and to "enjoin Apple from further interference with Qualcomm's agreements with the companies that manufacture iPhones and iPads for Apple."
Qualcomm said in a statement that Apple had broken and misrepresented agreements and negotiations, encouraged regulatory attacks against Qualcomm around the world, opted "not to utilize the full performance of Qualcomm's modem chips in its iPhone7".
"Apple could not have built the incredible iPhone franchise that has made it the most profitable company in the world, capturing over 90 percent of smartphone profits, without relying upon Qualcomm's fundamental cellular technologies," Qualcomm said.
"Now, after a decade of historic growth, Apple refuses to acknowledge the well established and continuing value of those technologies."
