Nokia owns tens of thousands of patents, inherited in part from its takeovers of NSN in 2013 and Alcatel-Lucent earlier this year. The company has made licensing a key part of its growth strategy.
The court action was filed with the Regional Courts in Dusseldorf, Mannheim and Munich in Germany and the US District Court for the Eastern District of Texas, covering 32 patents in all. These cover technologies such as display, user interface, software, antenna, chipsets and video coding. Nokia said it is in the process of filing further actions in other jurisdictions.
Apple has already counter-sued in the US District Court for Northern California, the Wall Street Journal reports. The company claims that Nokia excluded some patents from their agreement in 2011 and transferred them to third-party companies "to be used for extorting excessive royalties" from Apple. It asked the court to award damages and rule that Nokia breached its contract.
A day after the initial announcement, Nokia said it filed more lawsuits in additional countries. These cover a total 40 suits in 11 countries, including Germany, Finland, the UK, Italy, Sweden, Spain, The Netherlands, France, Hong Kong, Japan and the US, including the International Trade Commission.
