BlackBerry's tired of waiting for Facebook's friend request. So it sued.
The Canadian phone maker sued the world's largest social network in Los Angeles court, according to a report from Reuters.
The suit, which is not yet available online, targets Facebook and its Instagram photo sharing app and WhatsApp messaging service, BlackBerry said in a statement. It came after what BlackBerry said was "several years of dialogue" with the social network.
"As a cybersecurity and embedded software leader, BlackBerry's view is that Facebook, Instagram, and WhatsApp could make great partners in our drive toward a securely connected future, and we continue to hold this door open to them," BlackBerry said.
Facebook did not immediately respond to a request for comment.
BlackBerry, which nearly a decade ago was one of the world's largest smartphone makers, has in the last several years retreated into supplying business software and services. Likewise, its software also powers many in-car systems, and the company is placing a bet on smart cars with partner and mobile chip giant Qualcomm.
BlackBerry phones remain, but only because Chinese consumer electronics maker TCL, best known for budget televisions, pays BlackBerry for the rights to use its name.
One of the core services found on its older phones is BlackBerry Messenger (BBM), a secure way to exchange text and images and early competitor to the likes of WhatsApp. BBM was an attractive form of global communication, particularly in countries where text message rates were high.
But in the years since, Facebook and its subsidiaries have become go-to services replacing many of BBM's functions. Facebook alone is the world's largest social network, with more than 2 billion people logging in each month. WhatsApp, meanwhile, has become a de facto text message replacement, garnering 1.5 billion active users, according to data compiled by Statista.
