Sony settled a patent infringement lawsuit with Immersion in March 2007 following a lengthy legal battle. The settlement cleared the way for incorporating the missing "rumble" feature that the Sixaxis lacked.[13] Both the vibration function and motion-sensing capabilities of the DualShock 3 can be used simultaneously without one interfering with the other. Like the Sixaxis, it also has a USB mini-B port for charging and can also be used on a PSP Go via Bluetooth, though the controller and the PSP Go must be registered using a PS3 console.
