Munich officials have made an EU trademark application for Oktoberfest. Media have made out that they were seeking copyright protection but it is an actual trade mark application (I will do a post on the differences).
They claim that they have not made any money from the billion euro a year generating festivals. If the trademark is granted then the city will grant licenses for the use of the name throughout the EU they hope. It wont necessarily be that simple as there are already similar registered trademarks in the EU. An application in Germany prior to or at the same time as the EU application may have assisted the authorities.
