In 2006, Autodesk applied for registration of US trademarks on "DWG", "DWG EXTREME", "DWG TRUECONVERT", "REALDWG", "DWGX", "DWG TRUEVIEW". As early as 1996, Autodesk has disclaimed exclusive use of the DWG mark in US trademark filings. Out of these applications, only TRUSTEDDWG has been registered as a trademark by the USPTO.

In June, 2011 the USPTO issued a final refusal to register DWG as a trademark owned by Autodesk.
