It appears that Autodesk has not given up attempting to register DWG as a trademark in the European Union.
June 3: a letter from the EU's trade marks department:
The Office informs you that the above indicated application DWG has been refused on 07/05/2008 (the applicant has a right to appeal against this decision from that date).
I find it fascinating that the decision was made on May 7, and then it took nearly a month to write the letter letting the applicant know.
Another point of interest: the letter is addressed to Autodesk in San Rafael, California, Estados Unidos (De America). Some conspirists might see this as creeping Spanish bi-bilingualism, but the reason for the Spanish spelling is that the office of European trademark department is located in Spain.
July 2: Autodesk's attorney turns down his right to appeal:
The Applicants are no longer interested in the further prosecution of the above-numbered  application and in the circumstances, it is respectfully requested that the same be treated as withdrawn.
July 8: Opposition closed, and the CTM [community trade mark] is withdrawn. Autodesk's attempt to register DWG in Europe had been challenged by:
- Knowledge Base Software -- on grounds of (1) earlier sign, and (2) right to prohibit use of later TM under national law.
- SolidWorks-- on the grounds of (1) identity of marks, goods & services, and (2) likelihood of confusion.
This EU Web page provides a summary of the status of all DWG-related trademarks being applied for in Europe:
- REALDWG by Autodesk -- unopposed.
- TRUSTEDDWG by Autodesk -- opposed by Safelayer Secure Communications of Spain on grounds of likelihood of confusion, but I found no use of TrustedDWG by Safelayer.
Not that Autodesk is the only trademark victim. SolidWorks is attempting to register:
- DWGGATEWAY -- opposed by Autodesk for likelihood-of-confusion.
- DWGDITOR -- opposed by Autodesk for reasons of (1) earlier non-registered trademark and (2) right to prohibit use of later trademark under national law.
July 3: The day after the first lawyer abandoned the appeal, Autodesk hires new lawyers. Field Fisher Waterhouse sends the EU trademark office the Notice of Appeal.
July 10: EU trademark office says it doesn't care if Autodesk has new lawyers, and is doubtful the appeal can be re-opened:
Therefore, the appeal is likely deemed to be inadmissable.
Nevertheless, the trademark office invites Autodesk to send comments within the next two months.
