In a shocking move, BlackBerry has filed a lawsuit in California against Facebook, along with its subsidiaries WhatsApp and Instagram, for infringing on its messaging patents.
BlackBerry claims in the lawsuit that the social media companies developed messaging applications that "co-opt BlackBerry's innovations" by using patented features touching on security, the user interface, and battery life.

"We have a strong claim that Facebook has infringed on our intellectual property, and after several years of dialogue, we also have an obligation to our shareholders to pursue appropriate legal remedies," a spokesperson for BlackBerry said.
Facebook brushed off the suit as little more than a desperate move from a fading company. "Blackberry's suit sadly reflects the current state of its messaging business. Having abandoned its efforts to innovate, BlackBerry is now looking to tax the innovation of others. We intend to fight" Paul Grewal, Facebook's deputy general counsel, said in a statement.
