An anonymous reader writes "On March 16th, the United States Patent and Trademark Office issued a very broad patent on motion control in computing devices, one that seems to cover any smartphone that uses a built-in accelerometer. It was filed in July 2006 and preceded by a nearly identical patent granted in 2004 after a 2001 application. So it predates many of today's popular smartphones — the iPhone, the DROID, the Nexus One, etc. What will happen if the company that owns the patent asserts it?"
