Nokia wants the US International Trade Commission (ITC) to ban the import of Qualcomm chipsets that allegedly infringe on five patents held by the Finnish handset maker.
"We're alleging that Qualcomm has engaged in unfair trade practices through infringement of certain Nokia patents," said Rick Simonson, Nokia's chief financial officer, in a podcast released to explain details of a complaint filed with the ITC.
The patents that Nokia claims have been infringed by Qualcomm are related to chipsets used in mobile phones, including 3G (third-generation) handsets
"We've requested the ITC, first that they initiate an investigation and ultimately what we're looking for is for them to issue an exclusion order to bar the importation of the relevant infringing Qualcomm chipsets and the products that contain them from coming to the United States," Simonson said, alleging that Qualcomm copied Nokia's technology.
Nokia's action steps up an ongoing legal dispute with Qualcomm. For nearly two years now, the two companies have squared off against each other over patent licensing, resulting in several lawsuits.
Last year, Qualcomm filed a complaint against Nokia with the ITC over GSM (Global System for Mobile Communication) patents, and a hearing on that case is scheduled to be held next month, Simonson said.
More recently, the two companies squabbled over the renewal of a patent licensing agreement that expired in April.
