Oracle has filed a lawsuit against Google charging that its Android phone software [reportedly] "infringes Oracle patents and copyrights related to Java." According to a company representative: "You can't just take a Java application from a Sun environment, where it's licensed, and run it on Android. You have to recompile it to Dalvik."
Oracle alleges that Google was aware of its patents and "willfully and deliberately" infringed them. It also says Google hired some of Sun's Java engineers.[via ComputerWorld]
