From 1982 to 2009, Autodesk created versions of AutoCAD which wrote no fewer than 18 major variants of the DWG file format, none of which is publicly documented.The DWG format is probably the most widely used format for CAD drawings. Dwg filename extension) was the native file format for the Interact CAD package, developed by Mike Riddle in the late 1970s, and subsequently licensed by Autodesk in 1982 as the basis for AutoCAD.

The most successful is Open Design Alliance, a non-profit consortium created in 1998 by a number of software developers (including competitors to Autodesk), released a read/write/view library called the OpenDWG Toolkit, which was based on the MarComp AUTODIRECT libraries. Several companies have attempted to reverse engineer Autodesk's DWG format, and offer software libraries to read and write Autodesk DWG files. Autodesk sells a read/write library, called RealDWG, under selective licensing terms for use in non-competitive applications. As the biggest and most influential creator of DWG files it is Autodesk who designs, defines, and iterates the DWG format as the native format for their CAD applications. There are several claims to control of the DWG format.

This file is a Trusted DWG last saved by an Autodesk application or Autodesk licensed application.' This helped Autodesk software users ensure that the files they were opening were created by an Autodesk, or RealDWG application, reducing risk of incompatibilities. In 2006 Autodesk modified AutoCAD 2007, to include 'TrustedDWG technology', a function which would embed a text string within DWG files written by the program: 'Autodesk DWG. This function was supported by an encrypted checksum and product code (called a 'watermark' by Autodesk), written into DWG files created by the program.

Nine days later, Autodesk's attorneys won a broad and deep temporary restraining order against the Open Design Alliance. Autodesk trademark On November 13, 2006, Autodesk sued the Open Design Alliance alleging that its DWGdirect libraries infringed Autodesk's trademark for the word 'Autodesk', by writing the TrustedDWG watermark (including the word 'AutoCAD') into DWG files it created. It can read DWG files from version R13 up to 2021, and write R2000 DWG files.Also in 2008 Autodesk and Bentley Systems agreed on exchange of software libraries, including Autodesk RealDWG, to improve the ability to read and write the companies' respective DWG and DGN formats in mixed environments with greater fidelity.In addition, the two companies will facilitate work process interoperability between their AEC applications through supporting the reciprocal use of available Application Programming Interfaces (APIs). Created in late 2009, GNU LibreDWG is a free software library released under the terms of the GNU GPLv3 license. Therefore, the FSF placed the goal 'Replacement for OpenDWG libraries' in 10th place on their High Priority Free Software Projects list.

Out of these applications, only TRUSTEDDWG has been registered as a trademark by the USPTO. As early as 1996, Autodesk has disclaimed exclusive use of the DWG mark in US trademark filings. In 2006, Autodesk applied for registration of US trademarks on 'DWG', 'DWG EXTREME', 'DWG TRUECONVERT', 'REALDWG', 'DWGX', 'DWG TRUEVIEW'. Others point out that the failure of '100% compatibility' means only that loading such a drawing triggers an essentially irrelevant warning message when the file is opened in AutoCAD. The effect of the temporary restraining order and subsequent consent decree was to render the Open Design Alliance's DWGdirect libraries, from one point of view, incapable of creating DWG files that are 100% compatible with AutoCAD Unsubstantiated claim.

The USPTO office actions notifying Autodesk of this noted that Autodesk was not the exclusive source of files with the format name DWG, and Autodesk does not control the use of DWG by others, either as a trademark or as a file format name, among other points.In 2006, Autodesk filed an opposition with the USPTO to the trademark registration of DWGGATEWAY by SolidWorks. As of June 22, 2008, all of Autodesk's DWG-related trademark registration proceedings were suspended by the USPTO, pending disposition of trademark opposition and cancellation petitions Autodesk had filed against the Open Design Alliance and Dassault SystГЁmes SolidWorks Corporation. In September 2007, Autodesk responded, claiming that DWG has gained a 'secondary meaning,' separate from its use as a generic file format name. The DWG EXTREME, DWG TRUECONVERT, and DWG TRUEVIEW trademark registration applications all received substantial resistance, with the USPTO examining attorney requiring Autodesk to disclaim exclusive use of DWG as a condition for their registration.In a non-final action in May 2007, the USPTO examining attorney refused to register the two DWG marks, as they are 'merely descriptive' of the use of DWG as a file format name.

This cancellation action was suspended pending disposition of Autodesk's US District Court suit against SolidWorks. In early 2007, Autodesk petitioned the USPTO to cancel the Open Design Alliance's 'OpenDWG' trademarks, claiming that they had been abandoned. In both cases, Autodesk's basis was that they had 'been using the DWG name with its CAD software products since at least as early as 1983.' The opposition and cancellation actions were consolidated, and suspended pending disposition of Autodesk's US District Court suit against SolidWorks.

In June 2011 the USPTO issued a final refusal to register DWG as a trademark owned by Autodesk. In March 2010, the Office of the Deputy Commissioner for Trademark Examination Policy at the USPTO determined that evidence submitted by the Open Design Alliance two years earlier was relevant and supported a reasonable ground for refusal to register DWG as a trademark. Because there was no adjudication in either case, the agreements between the parties are not binding upon the USPTO. In April 2010, Autodesk and the Open Design Alliance settled their suit, with the Open Design Alliance agreeing to cancel its DWG-based trademark registrations and cease use of DWG and DWG-based trademarks in its product marketing and branding. In January 2010, on the morning that trial was scheduled to begin, Autodesk and SolidWorks settled the suit, with SolidWorks acknowledging Autodesk's trademark rights for DWG, surrendering its trademark registrations for its DWG related projects, and withdrawing its opposition to Autodesk's DWG-related trademark registrations.

Despite this, Autodesk websites still claimed DWG as a trademark after the decision. The USPTO affirmed in 2013 their refusal to recognise DWG as a trademark. Dwg is a file format used for computer-aided design (CAD) drawings made both with applicant's CAD software and others' CAD software.Autodesk appealed the decision.
