Facebook and two subsidiaries, WhatsApp and Instagram, sued by the BlackBerry for allegedly infringing copyright.
Based on claims posted by the BlackBerry, Facebook and both subsidiaries are accused of stealing features and technologies contained in the BlackBerry Messenger service (BBM). There are about 7 patents software that according to BlackBerry traced Facebook and his company.
According to a BlackBerry spokesperson, Sarah McKinney, the lawsuit was followed after a deadlock in dialogue between the two sides for several years.

"Facebook and its companies are developing apps that compete inappropriately by using copyright used on BlackBerry messaging," says McKinney
