Software and OS design tech firm Surf Cast has filed a suit in Maine over Live Tiles, which it says it invented.
The company has just four patents, but one of them, filed in 2000 and granted in 2004, deals with a "system and method for simultaneous display of multiple information sources".
Given the nature of this process, we have set as a target to reach 80% of our European volume by the end of 2017.
Today, already more than half of our consumer facing packing in Europe carries the information.
"A Tile is different from an icon because it can be both selectable and live - containing refreshed content that provides a real-time or near-real-time view of the underlying information," the site says.
