Facebook Inc is accusing BlackBerry Ltd for patent infringement, escalating the legal battle between the two companies over protected technology. In a 118-page complaint filed on Tuesday in San Francisco federal court, Facebook accused BlackBerry of stealing its voice messaging technology, when compared with other patented processes. Facebook is searching unspecified damages for infringement of six patents.
BlackBerry didn’t immediately replied to messages sent outside regular business hours seeking comment on the suit. Along with the voice-messaging patent, Facebook cites infringement of patented technology that enhances how a mobile device delivers graphics, video and audio and another that centralizes tracking and analysis of GPS data. In March, BlackBerry sued Facebook in federal court in Los Angeles, suing the social media giant of infringing on its mobile messaging patents.
