If that case is indeed the right one, the complainants have had a trademark on their mark since 1953, and yet they let the domain be first registered in 2005, and then bought by the current owner in 2011.
So, they could either have created the domain before 2005 or buy it between 2005 and 2011, but they chose to go against the current owner in June of this year only.
There should be laws against such carelessness.
