Apple filed a motion specifying five patents that are allegedly infringed on by the S4 and two patents that are allegedly infringed on by the Google Now app.
Here's the patents that Apple references:
● Two "Siri" patents on unified search: U.S. Patent No. 8,086,604 and U.S. Patent No. 6,847,959 on a "universal interface for retrieval of information in a computer system"
● U.S. Patent No. 5,666,502 on a "graphical user interface using historical lists with field classes"
● U.S. Patent No. 5,946,647 on a "system and method for performing an action on a structure in computer-generated data" (which I dubbed the "data tapping" patent, a term many reporters have since adopted)
● U.S. Patent No. 7,761,414 on "asynchronous data synchronization amongst devices"
Originally Apple asserted patents '604 and '959 against the Android Quick Search Box but it is now updating its infringement contentions to apply to the newly released Google Now.
