I've just awarded a barnstarhttp://en.wikipedia.org/wiki/User_talk:EJSawyer#Precedent_Barnstarto an editor who contributed a key word to an article quoted by the Trademark Trial and Appeal Board in the case *In re Trek 2000*.
As it turns out, the TTAB allows references to Wikipedia, which I find to be insane. An IP attorney blogging about the decision gamely noted that "Wikipedia is available for posting a favorable entry regarding [trademarks]"!http://thettablog.blogspot.com/2010/12/precedential-no-43-ttab-reverses.html
