BlackBerry sues Facebook, WhatsApp, Instagram over patent infringement
BlackBerry is trying to persuade other companies to pay licensing royalties to use its trove of more than 40,000 global patents on technology including operating systems, networking infrastructure, acoustics, messaging, automotive subsystems, cybersecurity and wireless communications.BlackBerry is also selling cybersecurity software for self driving cars. BlackBerry sued Nokia Corp in February 2017, alleging infringement of patents relating to 3G and 4G wireless communications technology. That case is still pending in federal court in Delaware. Last year Qualcomm Inc agreed to pay BlackBerry $940 million to resolve arbitration over royalty payments. In October 2017 BlackBerry announced a confidential settlement with Blu Products Inc, a Florida-based maker of low-cost mobile devices it had also sued for patent infringement.
