The Canadian technology company alleged that the world's largest social media and its proprietary apps have copied the technology and features of BlackBerry Messenger.
At one time the smartphone market dominated, but at one point in the market share blackberry, closes the smartphone. Since then, Chief Executive John Chen took the new tactics to finance the organization. Reuters reported that the case of patent infringement was part of this strategy.
In a lawsuit filed in federal court in Los Angeles, BlackBerry said, "The accused have built mobile messaging applications in which BlackBerry inventions have been added, in this case they have used multiple innovative security, user interface and functionality enhancements."
Blackberry spokesman Sarah McKinney said in an e-mail: "The responsibility of every shareholder to protect the shareholders' wealth and intellectual property." But this case is Blackberry's "nothing of the strategy".
After a few years of negotiations, the case has been filed. BlackBerry has a responsibility to shareholders to bring the appropriate legal solution, he said.
Facebook's deputy general counsel Peil Grioyl said in a statement that the company will fight this case. He said, "Blackberry's case shows sadly the current situation in the messaging business. Due to innovation, BlackBerry is looking at income from the inventions of others. "
BlackBerry has more than 40,000 patents worldwide in the technology sector including operating systems, networking infrastructure, messaging, automation subsystems, cyber security and wireless communications. By providing these patent licensing services, BlackBerry is now trying to earn money from other organizations.
