Nokia’s has made a comeback to Smartphone business. It seems to be going well but company’s mobile equipment business has now come under spotlight as BlackBerry is said to have filed a patent-infringement case against the Finnish company. BlackBerry claims that Nokia’s mobile network products use technology that is covered by as many as 11 of its patents.

BlackBerry Ltd. filed a patent-infringement lawsuit against Nokia Oyj, demanding royalties on the Finnish company’s mobile network products that use an industry wide technology standard.


  • BlackBerry says it is not seeking the block of technology use
  • The company says Nokia was aware of the inventions
  • Nokia allegedly tried to buy the patents earlier

BlackBerry enlisted in this complain and  said 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 in federal court in Wilmington, Delaware, USA.

The mobile products by Nokia that are the subject of complaint are provided to carriers including T-Mobile US and AT&T for their LTE networks, BlackBerry also said that  as per the report. “Nokia has persisted in encouraging the use” of the products that are compliant to these industry standards but without a license from BlackBerry, the company was quoted as saying in Bloomberg report.

BlackBerry is now looking to get “recompense” for what the company says is “unauthorized” use of its patented technology by Nokia. The Waterloo, Canada-based Company said in the complaint that BlackBerry didn’t specify how much it’s seeking.

John Chen, the Chief executive officer is working to find new ways to pull revenue out of BlackBerry’s technology as Smartphone sales head to zero. 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 has further mention that Nokia is well aware of the inventions as the company has cited some of the patents in its own patent applications.
