Facebook files suit against BlackBerry over voice messaging tech patent infringement

Looks like there’s no love lost between Facebook and BlackBerry. Months after BlackBerry filed a lawsuit against the social network claiming it stole key technology related to mobile messaging that have “made BlackBerry’s products such a critical and commercial success in the first place,” Facebook seems to be returning the favour. Facebook claims BlackBerry has infringed on six of its patents related to a voice messaging feature in BBM Enterprise. It claims BlackBerry violated its patents in the way mobile devices deliver images and audio as well as with patents related to GPS data management and security. The social network filed the suit in San Francisco federal court and is seeking unspecified damages.
