A trademark application for "dotsport" has been made by Patrick Vande Walle to the Office for Harmonization in the Internal Market. While there is not much information available, could this be the prelude to an application for a .sport gTLD application?
The trademark application is available from oami.europa.eu/CTMOnline/RequestManager/en_SearchBasic_NoReg by searching for the trademark number "005906953".
