BlackBerry drags Nokia to court for alleged patent infringment


Nokia is gearing up for its return to the smartphone market, but BlackBerry going after the Finnish company through patent infringement lawsuit.

According to BlackBerry, Nokia’s mobile network products use technology that is covered by as many as 11 of its patents. BlackBerry has pointed out in the complaint that Nokia’s products including Flexi Multiradio base stations, Liquid Radio software, and radio network controllers are using the technology that is covered by BlackBerry patents. The complaint by BlackBerry has been filed earlier this week in federal court in Wilmington, Delaware, USA.

BlackBerry also noted in the complaint that Nokia products that infringe on its patents are provided to carriers including T-Mobile US and AT&T for their LTE networks. BlackBerry claims that Nokia continues to encourage people to use its products that infringe on BlackBerry patents without having a license.

BlackBerry is going after Nokia to get “recompense” for what it believes is “unauthorised” use of its patented technology by Nokia. BlackBerry claims that Nokia is already aware of the patents that BlackBerry has on its name as the Finnish company has cited some of the patents in its own patent applications.

Notably, some of the patents involved in the case earlier belonged to Nortel Networks Corp and Nokia tried to buy them with a bid that eventually failed in 2009, as per BlackBerry. However, BlackBerry, as part of a consortium called Rockstar (which also included Microsoft and Apple) managed to buy these patents from Nortel.

Since the patents cover essential elements of 3GPP mobile telecommunication standard, BlackBerry says it is not seeking to block the use of technology entirely but looking to license them on fair and reasonable terms, as per the report.
