Microsoft Corp. (MSFT) and Google Inc. (GOOG) were accused of violating a Louisiana company’s patent covering mapping technology that helps computer users see locations in three dimensions.



From Bloomberg:
The companies’ misuse of the mapping technology “has injured Transcenic and Transcenic is entitled to recover damages adequate to compensate for such infringement,” the closely held Lake Charles, Louisiana-based company said today in a suit filed in federal court in Wilmington, Delaware.

Patents covering computer-mapping software have sparked litigation against Google, Microsoft and other companies in federal courts around the U.S. GeoTag Inc. has filed patent- infringement suits against 300 entities, many of which use mapping technology made by Redmond, Washington-based Microsoft or Mountain View, California-based Google to show store locations.
