BlackBerry Sues Nokia For Patent Infringement

BlackBerry filed a suit against Nokia on February 14, 2017, at the federal court in Wilmington, Delaware.

According to a lawsuit filed in DE this week, first spotted by Bloomberg, BlackBerry accused Nokia of "egregious infringement" of its patented 3G and 4G technology.


Blackberry and Nokia have already moved away from making smartphones and their own handsets.

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.
According to the filing BlackBerry has demanded royalties for Nokia's mobile network products, and alleged that the Finnish company has infringed on 11 patents. Outside of licensing deals and software, it looks like BlackBerry also wants to try and make some cash from its patents as today BlackBerry filed a lengthy 96-page complaint (via ars technica)against Nokia, accusing the company of infringing on 11 of its patents. The patents span OFDM, a channel estimation method for MIMO-OFDM systems, a method of detecting the number of transmitting antennas in a base station, the combined use of space-time coding and spatial multiplexing as well as the use of orthogonal transformation in space-time coding, a system for multi-carrier network operation, and a multi-beam cellular communication system, among other things.


Nokia has not responded to this lawsuit at the time of writing, nor do we know how much money BlackBerry is seeking out of this legal complaint. He's used acquisitions to add a suite of software products and negotiated licensing agreements to take advantage of the company's thick book of wireless technology patents.

BlackBerry is now looking to get "recompense" for what the company says is "unauthorised" use of its patented technology by Nokia.
