BlackBerry has filed a lawsuit against Nokia alleging Nokia to infringe on its 11 patents. The suit filed with a federal court in Wilmington, Delaware alleges Nokia of Infringing on patents, across various mobile networking products that use an industrywide technology standard. The infringing products include Flexi Multiradio base stations, radio network controllers, and Liquid Radio software.

These mobile network products and services are provided to companies including two major US carriers T-Mobile and AT&T for their 4G LTE networks. Some of these patents were previously owned by Nortel Networks Corps which went bankrupt in 2011. Blackberry along with Apple and Microsoft was part of the consortium which bought Nortel’s patents.

According to BlackBerry, the patents cover necessary elements of a mobile telecommunications standard known as 3GPP. BlackBerry vows to license those patents on fair reasonable terms and is not seeking to block the use of the patents.

BlackBerry said in the complaint. “Nokia has persisted in encouraging the use of the standard- compliant products without a license from BlackBerry.BlackBerry seeks to obtain recompense for Nokia’s unauthorized use of BlackBerry’s patented technology,” BlackBerry didn’t specify how much it’s seeking.
