BlackBerry Ltd has filed a patent infringement lawsuit against Facebook Inc and its WhatsApp and Instagram units.
BlackBerry is arguing that Facebook, WhatsApp and Instagram copied technology and features from BlackBerry Messenger.
Litigation on alleged patent infringement is thought to be part of BlackBerry CEO John Chen’s strategy for making money.
BlackBerry wants other companies to pay licensing royalties to use its portfolio of more than 40,000 patents.
BlackBerry spokeswoman Sarah McKinney told Reuters in a statement: “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.”
BlackBerry alleged in a filing with a Los Angeles federal court: “Defendants created mobile messaging applications that co-opt BlackBerry’s innovations, using a number of the innovative security, user interface, and functionality enhancing features.”
Facebook deputy general counsel Paul Grewal said in a statement the company intends to fight the lawsuit.
“Blackberry’s suit sadly reflects the current state of its messaging business,” Grewal said.
“Having abandoned its efforts to innovate, Blackberry is now looking to tax the innovation of others.”
