Samsung sues to block iPhone 4S in Australia

Samsung is suing Apple to stop sales of the iPhone 4S in Australia, just days after the device went on sale around the world. Both companies are now shelling out millions in legal fees to fight more than 20 patent infringement cases in 10 countries. Samsung recently vowed to shift its strategy from "passive" to being "more aggressive" in targeting Apple for "free riding" on its patents.
