Communications giant Nokia is suing Apple for alleged infringement of 32 technology patents. The lawsuit is being brought against the iPhone maker in Germany and the US.

In 2011, Nokia and Apple agreed a license covering some of Nokia’s patents. The Finnish multinational says that Apple has ‘declined subsequent offers made by Nokia to license other of its patented inventions which are used by many of Apple’s products’.

“Through our sustained investment in research and development, Nokia has created or contributed to many of the fundamental technologies used in todays 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 Apples use of these patents, we are now taking action to defend our rights.”

The 32 patents cover technologies including display, user interface, software, antenna, chipsets and video coding. The case has been filed with the Regional Courts in Dusseldorf, Manmheim and Munich in Germany and the US District Court for the Eastern District of Texas. Nokia says it is in the process of filing further actions in other jurisdictions.
