Facebook claims BlackBerry stole its voice messaging technology

Facebook is suing BlackBerry for patent infringement, according
to a report from
. The lawsuit comes just months after

BlackBerry sued Facebook
, alleging that the social media
company and its WhatsApp and Instagram subsidiaries infringed
on BlackBerry messaging app patents.

In the complaint, filed in San Francisco federal court,
Facebook accuses BlackBerry of infringing on several patented
processes and technologies surrounding voice messaging, how a
mobile device delivers graphics, and the tracking and analysis
of GPS data. In total, Facebook is asking for unspecified
damages for infringement of six patents.

Back in March, BlackBerry sued Facebook, saying that the
company was “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.” Some of the patents in question cover
interface elements as broad as the displaying of message
timestamps and the ability to tag friends and family in photos.
BlackBerry and its BBM system rose to popularity in the mid to
late-2000s, while
Facebook’s Messenger spun out of the core app in 2013

By spring 2014
, Facebook turned off the ability to send
messages in the original app, forcing users to migrate to the
standalone Messenger.
