Apparently, BlackBerry has lifted a technology, which improves how a mobile device delivers graphics, video and audio, and another one, which centralises tracking and analysis of GPS data. “Facebook is seeking unspecified damages for infringement of six patents.” For the uninitiated, this filing by Facebook is part of a long-standing back and forth between the company and BlackBerry. In March this year, **BlackBerry had sued Facebook** saying that the company is infringing on its mobile messaging patents. “BlackBerry claimed Facebook made unauthorized use of its technology in its own instant messenger service, Facebook Messenger, and in WhatsApp Messenger and Instagram.” A final decision on this back and forth sue-slapping hasn’t been declared yet.
Facebook has accused BlackBerry for infringement of a total of six protected technologies.
