Nokia has filed new lawsuits against Apple in the US and Germany that levy accusations of patent infringement in Apple devices.
This is the latest in a series of legal scuffles over patents between the two companies.
Finland-based Nokia previously sued California-based Apple in 2009, alleging that the iPhone infringed patents for touch screen technology in smartphones owned by Nokia. That case was settled in 2011.
Nokia alluded to the settlement in a statement Wednesday, saying that in 2011 Apple had agreed to "a license covering some patents from the Nokia Technologies portfolio."
But, "Apple has declined subsequent offers made by Nokia to license other of its patented inventions which are used by many of Apple's products," Nokia said in the statement.
Nokia said the lawsuits involve 32 patents that cover display, user interface, chipset, antenna and other technologies.
Apple did not immediately respond to a request for comment Wednesday.
Meanwhile, Apple has accused Nokia of working with Acacia Research Corporation, a "patent assertion entity", to "extract and extort exorbitant revenues unfairly and anti-competitively from Apple and other innovative suppliers of cell phones," according to a lawsuit filed by Apple on Wednesday.
