KEY POINTS
  • BlackBerry is claiming infringement on patents it holds covering message encryption, battery and message notifications, and combining messaging with gaming, according to the lawsuit.
  • Blackberry is seeking injunctive relief and damages accounting for lost profits. No specific dollar figure was given.
  • The company claims Facebook and its wholly owned services — Instagram and WhatsApp, which are also named as defendants in the suit — are "relative latecomers to the mobile messaging world."

BlackBerry is suing Facebook for patent infringement, alleging many of the features of Facebook's messaging services infringe on BlackBerry patents, the company said Tuesday.

"[W]e have a strong claim that Facebook has infringed on our intellectual property, and after several years of dialogue, we also have an obligation to our shareholders to pursue appropriate legal remedies," BlackBerry said in a release.
