Nokia is suing Apple again for allegedly infringing on 40 of its patents.
The manufacturer is claiming that Apple refused to license inventions already patented by Nokia even after the previous settlement. Nokia has filed 14 complaints in 11 countries to fight Apple.
Nokia claims to have tens of thousands of patents that cover a range of devices including smartphones and PCs. Its patents cover display technology, antennas, video coding, and more.
"Through our sustained investment in research and development, Nokia has created or contributed to many of the fundamental technologies used in today's mobile devices, including Apple products," said Ilkka Rahnasto, head of Patent Business at Nokia.
"After several years of negotiations trying to reach agreement to cover Apple's use of these patents, we are now taking action to defend our rights."
Most recently, phone manufacturer HMD Global acquired the rights to the Nokia franchise. It plans on bringing the brand to Android phones in 2017.
