Qualcomm claimed Nokia is violating two of its patents in a suit it filed in the Western District of Wisconsin on April 2, 2007. Nokia said Qualcomm has filed 11 patent cases in all against it.
In the same court, Nokia just filed charges that Qualcomm is infringing six Nokia implementation patents used in Qualcomm GSM/WCDMA and CDMA2000 chipsets. Nokia said that since Qualcomm is seeking injunctions against it, it is requesting the same in its suit.
Qualcomm is also embroiled in a bitter patents fight with Broadcom.
