On November 2nd of this year, WWE registered the trademark "WORLD WRESTLING FEDERATION", with the usage explanation being, "Entertainment services, namely, the production and exhibition of professional wrestling events rendered live and through the media of television; providing wrestling news and information via a global computer network." At this point in time, WWE is prohibited from using the WWF name due to the lawsuit that they lost with the World Wildlife Fund a few years ago. Whether they are covering their bases or plan to make an offer to the Fund which will allow them to use the name again isn't known at this time.
