BlackBerry is accusing Facebook of infringing on its messaging technology, and the device maker is suing.
The lawsuit filed in Los Angeles accuses Facebook, WhatsApp, and Instagram of using BlackBerry's early ability to send text messages without incurring standard rates (known as BlackBerry Messenger or "BBM"), along with certain interface features like the ability to tag friends and family in photos.
In a statement from Facebook’s Deputy General Counsel Paul Grewal, Facebook dismissed BlackBerry’s claims and promised to fight.
“BlackBerry’s suit sadly reflects the current state of its messaging business,” the statement reads. “Having abandoned its efforts to innovate, BlackBerry is now looking to tax the innovation of others. We intend to fight.”
