After taking on a legal battle with BLU Products and Avaya, BlackBerry has now filed a patent infringement lawsuit against Nokia. In the filing, BlackBerry Ltd. v. Nokia Corp., 17-155, U.S. District Court for the District of Delaware, BlackBerry claims Nokia's networking gear, including its Flexi Multiradio base stations, radio network controllers, and Liquid Radio software, infringes 11 patents.
The complaint was filed Tuesday in federal court in Wilmington, Delaware. In the complaint, BlackBerry notes that the company 'seeks to obtain recompense for Nokia's unauthorized use of BlackBerry's patented technology', but doesn't mention how much they're seeking, nor are they seeking any court order that would block use of the inventions. Instead BlackBerry is just looking to 'to license them on fair and reasonable terms' because according to BlackBerry 'Nokia has persisted in encouraging the use' without a license from BlackBerry as noted in the complaint.
Nokia encourages and instructs customers, mobile service providers such as T-Mobile and AT&T, to purchase, deploy and use infringing products to develop and operate their LTE networks and UMTS networks
The patents-in-suit are U.S. Patent Numbers 6,996,418; 8,254,246; 8,494,090; 7,529,305; 8,861,433; 9,426,697; 9,253,772; 8,897,192; 9,125,202; 8,243,683; and 8,644,829.
