Bloomberg reports that Facebook (NASDAQ:FB) is suing BlackBerry (NYSE:BB) for patent infringement pursuant to its voice messaging technology:

In a 118-page complaint filed Tuesday in San Francisco federal court, Facebook accused BlackBerry of stealing its voice messaging technology, among other patented processes. Facebook is seeking unspecified damages for infringement of six patents.

The lawsuit also cites infringement of technology that improves how mobile devices deliver graphics, audio and video and centralizes tracking of GPS data. In March, BlackBerry sued Facebook for infringing upon its technology for displaying mobile messages. With its lawsuit, Facebook may have flipped the script on BlackBerry and put the company on the defensive.
