Nokia Corporation announced that it has requested the ban of certain chipsets from being imported into the U.S. in a complaint just filed with the U.S. International Trade Commission (ITC). Nokia filed the request against chipset manufacturer Qualcomm Inc. based on allegations that certain chipsets infringe upon five Nokia patents in some GSM/WCDMA and CDMA2000 chipsets.

Nokia indicated that the patents relate to technologies that improve the performance of mobile devices, lead to longer battery life, allow for smaller size factor and help lower manufacturing costs. Nokia is the world’s largest mobile phone manufacturer, making more than one in three cell phones sold globally.

Nokia and Qualcomm have been feuding since a cross-licensing agreement covering technology patents expired in April and was not renegotiated. Their dispute has been growing more acidic over time and has industry experts concerned as to the effect the dispute may have across the industry.

While the fight centers around high-speed 3G wireless technology it also potentially impacts Qualcomm’s other chipsets, as Nokia claims these similarly rely on technologies that are patented by Nokia.
