On December 1, 2004, a patent was filed in the United States naming Apple as asignee (owner). Its title is "Universal interface for retrieval of information in a computer system." This patent, which you can find here, has become Apple's most effective weapon in its fight to see Android dubbed an iOS "ripoff" by courts and consumers.
