Earlier this week BlackBerry sued Facebook and its two apps, Whatsapp and Instagram over patent infringement. BlackBerry stated in a filing with a Los Angeles federal court: “Defendants created mobile messaging applications that co-opt BlackBerry’s innovations, using a number of the innovative security, user interface, and functionality enhancing features,”.

In fact this isn’t BlackBerry’s first case of patent infringement. In February 2017, the company sued Nokia over infringement of patents relating to 3G and 4G wireless communications technology and the case is still pending in the federal court of Delaware.

Currently, is trying to persuade other companies to pay licensing royalties for using its more than 40,000 global patents on technology including operating systems, networking infrastructure, acoustics, messaging, automotive subsystems, cybersecurity and wireless communications.
