Hello, I recently looked up the German Patent and Trade Mark Office's database for "Wikipedia". It resulted in two hits. One is about the trademark "Wikipedia" in the area of tents, clothes, shoes and sportsware and dates back to mid 2004. The other one is about the trademark "Wikipedia" in three classes containing a lot of IT related stuff including database service, data collecting, telecommunication in general, online informations services. Owner is a company called "Firestorm Forces Ltd." and searching on it together with Wikipedia I learned they're involved some bad anti-Wikipedia agitation. Seems they're also acting as "Infochannel Group" and as those clashed with german Wikipedians because of their entry ([[Infochannel Group]]) in de.wikipedia. They also run a site called Encyclopedia Wikimania (http://www.wikimania.co.uk), a quite strange one with no real content. I can't say if the classes they registered are relevant and interfere with what "our" Wikipedia does. But it might be and then it could become troublesome for us. The trademark was filed in November last year and puplicated on January 27th 2006. That means the opposition period end on April 27th. Maybe someone is interested in doing some more research and foundating might think about filing an opposition. Regards, Jürgen
