Finland-based Nokia today disclosed that it has filed suit against Apple in the U.S. and Germany, claiming that Apple products infringe on Nokia’s patents.

So far Nokia has filed lawsuits in the U.S. District Court for Texas’ Eastern District and in regional courts in Düsseldorf, Mannheim, and Munich. The relevant patents cover displays, chipsets, and software, among other things.

Nokia stock was halted earlier today on the release of the news.

“As one of the world’s leading innovators, and following the acquisition of full ownership of NSN in 2013 and Alcatel-Lucent in 2016, Nokia now owns three valuable portfolios of intellectual property,” Nokia said in a statement. “Built on more than EUR 115 billion invested in R&D over the past twenty years, our tens of thousands of patents cover many important technologies used in smartphones, tablets, personal computers and similar devices.

“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.”

Apple did not immediately respond to a request for comment.
