Facebook Inc. has sued BlackBerry Ltd. for allegedly infringing its patent of a technology that it claims it uses in voice messaging. The social media giant filed a 118-page complaint in a District Court in San Francisco, California accusing BlackBerry of “stealing its voice messaging technology, among other patented processes.” According to Bloomberg, Facebook is seeking unspecified damages for infringement of six patents.
“In addition to the voice-messaging patent, Facebook cites infringement of patented technology that improves how a mobile device delivers graphics, video and audio and another that centralises tracking and analysis of GPS data,” Bloomberg said in its report. The development comes five months after Blackberry Limited, the software company and not TCL, the BlackBerry smartphone manufacturer, filed a case against Facebook and its subsidiaries WhatsApp and Instagram alleging that the social media giant infringes upon BlackBerry’s messaging app patents.
In the case filed in March in Los angeles, California, BlackBerry sued Facebook in a federal court claiming that the latter made unauthorised use of its technology in its own instant messenger service, Facebook Messenger and in WhatsApp Messenger and Instagram. As per the lawsuit, Facebook “created mobile messaging applications that co-opt BlackBerry's innovations, using a number of the innovative security, user interface, and functionality enhancing features that made BlackBerry's products such a critical and commercial success in the first place.”
