BlackBerry on Tuesday filed a patent infringement lawsuit against Facebook and its WhatsApp and Instagram applications, arguing that they copied technology and features from BlackBerry Messenger.
Patent infringement litigation is part of BlackBerry Chief Executive John Chen's strategy for making money for a company that has lost market share in the smartphone that once dominated.
"Defendants have created mobile messaging applications that create BlackBerry innovations, use a range of innovative security features, user interfaces, and functionality-enhancing features," said a BlackBerry agency based in Canada, filed with the Los Angeles Federal Court.
"Protecting shareholders' assets and intellectual property is the responsibility of every CEO," said BlackBerry spokeswoman Sarah McKinney in an email. However, she noted that litigation was "not central to the BlackBerry strategy."
The lawsuit followed years of negotiation and BlackBerry has a duty of shareholders to enforce appropriate legal remedies, she added.
The deputy general adviser Paul Grewal said in his statement that the company intends to fight the lawsuit.
"Blackberry's suit unfortunately reflects the current status of his messaging," Grewal said. "Blackberry, who has abandoned his efforts to innovate, is now looking for taxation of others."
BlackBerry seeks to convince other companies to pay royalties for using more than 40,000 global technology patents including operating systems, network infrastructure, acoustics, messaging, automotive subsystems, cyber security, and wireless communications.
BlackBerry also sells cyber security software for self-propelled cars.
In February 2017, BlackBerry sued Nokia Corp for patent infringement for 3G and 4G wireless communications. In the case of Delaware, this case is still pending in the federal court.
Last year, Qualcomm Inc. agreed to pay BlackBerry $ 940 million (about $ 6,100,000) to deal with royalty payments.
In October 2017, BlackBerry announced confidentiality with Blu Products, a manufacturer of low-cost mobile devices in Florida.
