Blackberry has filed a lawsuit in the US blaming Facebook of copying features from Blackberry Messenger in an infringement of its patent rights.
Blackberry, which was at one time a pioneer in the smartphone business, says Facebook utilized the technology and features in its Instagram and WhatsApp applications.
The cases come after Blackberry has expanded endeavors to profit from its in excess of 40,000 patents.
Facebook has said it would fight the lawsuit.
Paul Grewal, deputy general counsel of Facebook, said Blackberry’s claim “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,” he said.
