Judge orders that the trademarketness of DWG go to jury

In Autodesk's law suit against SolidWorks over the use of DWG in product names and marketing, judge William Alsup rules:

There are genuine issues of material fact as to whether DWG is generic. Both sides will have to try and convince a jury. 

If the jury finds that DWG is generic, then Autodesk cannot register it as a trademark in the USA. The judge found sufficient arguments for both sides that he could not decide.

Even if the jury finds that DWG is non-generic, competitors are free to use the .dwg file extension, Autodesk vows:

Plaintiff  [Autodesk], however, expressly disavows any ownership of "any even arguably functional use of DWG", including the use of DWG as a file extension. Put differently, anyone is the world is free to use .dwg as a file extension as far as Autodesk is concerned. Thus, there is no concern that plaintiff will obtain a monopoly over the .dwg extension and prevent its use in the industry.
