Nokia announced on December 21st that it had sued Apple for patent infringement in the U.S. and Germany.
Since agreeing a license covering some patents from the Nokia Technologies portfolio in 2011, Apple has declined subsequent offers made by Nokia to license other of its patented inventions which are used by many of Apple's products.
Ilkka Rahnasto, head of Patent Business at Nokia, said: "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. 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."
In retaliation Apple removed Withings products from its online store. Withings was acquired by Nokia early this year for $192 million.
Additionally, Apple has also sued Nokia. FossPatents says that Apple is telling the courts: Nokia, after failing as a mobile device maker, changed its positions on FRAND licensing of standard-essential patents and conspired with various PAEs in order to bring numerous royalty demands and infringement lawsuits against Apple and other industry players and with the objective of circumventing its original FRAND licensing commitments.
Nokia has since expanded its lawsuit against Apple to eleven countries.
