As soon as the U.S. sales ban on the Galaxy Tab 10.1 was lifted, Samsung leaped back into the legal offensive, tacking on the iPhone 5 to its own patent claims against Apple.

The patents in question include six utility patents and two UMTS standard essential ones, which are all listed below.
*Method and apparatus for performing non-scheduled transmission in a mobile communication system for supporting an enhanced uplink data channel
*Method and apparatus for signaling control information of uplink packet data service in mobile communication system
