The guy filed a trademark as a response to Blizzard trademarking the name he had been using for over a year.Hooopy said:Finland use day/month/year as far as I can see, so according to the above info it would be after the blizz one.Is the "04.10.2013" respresenting April 10th 2013, or October 4th 2013?
Not saying he didn't have it first, he just didn't file until after blizz had so he's going to have an uphill battle if he wants to fight it.
[edit for terrible mobile phone post]
Anyway, according to European Trademark law the trademark goes to the first that used the name and was officialy making a product using it. And as Blizzard started the whole renaming business in 2013 and this guy used the name already in 2012 it goes to him. This will be an even battle as money does not hold power over law as incredibly much that they do in the U.S.
