Nokia countersues Qualcomm, seeks injunction

It seems that the continuing negotiations between Nokia and Qualcomm still did not result to a "mutually acceptable agreement."

Nokia has filed a countersuit in response to the case filed by the Qualcomm in the Western District of Wisconsin on April 2. The handset maker maintains that its products do not infringe either of the two Qualcomm patents-in-suit and asserts that both patents are invalid.

The Finnish company filed, in the same court, patent counter assertions against Qualcomm for its infringement of six Nokia implementation patents used in Qualcomm GSM/W-CDMA and CDMA2000 chipsets. The six patents are not essential for the practice of standards, however they provide substantial benefits when used. In its previous litigation filings, Qualcomm has sought injunctions against Nokia. This time, Nokia is seeking damages and an injunction against Qualcomm's infringing chipsets.

"Over the past 19 months Qualcomm has filed 11 patent litigation cases against Nokia seeking damages and injunctions," said Rick Simonson, Nokia chief financial officer. "Nokia has now filed its first counter action to address Qualcomm's unauthorized use of Nokia technology. We will continue to defend ourselves and exercise all rights according to our extensive IPR portfolio."

The implementation patents cited in the Nokia counterclaim filing relate primarily to multi-band/multi-mode technologies that allow seamless and transparent roaming for consumers, and direct conversion technologies, which reduce handset and chipset size, cost and power consumption. Nokia claims that, through its Qualcomm unauthorized use of the patents, has copied these innovations and made them available to its chipset customers.
