Qualcomm is suing Nokia over alleged patent infringement in relation to GSM and 2.5G mobile technology used in the Finnish company’s handsets.
The lawsuit comes days after Nokia and several other major mobile players complained to the European Commission that Qualcomm was acting unfairly in the way it was licensing some of its 3G technology to other companies.
The lawsuit from Qualcomm alleges that Nokia and its subsidiaries have broken patents related to delivering GPRS and Edge mobile data services on 2.5G networks, as well as patents covering standard GSM services.
Qualcomm wants damages and an order for Nokia to stop using the technology in question.
Nokia said it was surprised at the action and had yet to receive a copy of the complaint.
The company said it was disappointed “Qualcomm has taken this step given they have yet to engage in any licensing negotiations concerning these matters".
“Companies with essential and valid patents must agree to license those patents on fair, reasonable and non-discriminatory terms. It is quite unusual for a company to institute litigation before discussing such terms.
Qualcomm recently filed a lawsuit against Broadcom for the alleged misuse of patented technology, and Broadcom has countersued.
It also dismissed complaints to the European Commission by some of its rivals, as “legally merit-less”. The Commission is still considering whether to investigate.
Qualcomm recently reported a 40% increase in sales and 37% increase in net profits for the fourth quarter which ended on 25 September.
