Nokia, massive if alien-to-North America, sued Apple for WiFi/GSM/HSPA patent violation, at which point Apple spun around and counter-sued for iPhone patent violation, and now Nokia has yelled the legal equivalent of "fire everything!"
According to PC World:
Nokia fired the latest salvo in its ongoing patent dispute with Apple, saying Tuesday that it has filed a complaint with the U.S. International Trade Commission charging that Apple infringes its patents "in virtually all of its mobile phones, portable music players and computers."
The complaint involves seven patents that Nokia says Apple is using to "create key features" in products related to the user interface and camera, antenna and power management technologies. Nokia wants the ITC to investigate its claims.
So, if we can piece the story together as we've heard it rumored, Nokia is supposed to license it's pooled patents to Apple under the same equitable and reasonable terms as everyone else, but decided they wanted Apple to counter-license their iPhone patents to Nokia. Apple declined, Nokia sued, Apple counter-sued, and now Nokia is seeing them and raising the stakes -- to the very roof.
Nokia is huge, Apple has billions, this could drag on for years and years. We're guessing the execs don't care and neither do the lawyers.
