Apple and Nokia eventually reached an agreement on the use of patents that supposedly runs until the end of this year.
Nokia says that since agreeing to a license covering "some" of its patents 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" - and that's the reason for these new lawsuits.
