Existing registrants of 3rd level names have been using the names which may be familiar to their customers or foreign associates. To avoid possible confusion that can arise from others registering the same names at the 2nd level and to minimize the potential dispute cases between the parties registering the same name at the 2 levels, there is a need to let existing 3rd level name registrant decide first if they would also like to register the same name at the 2nd level.
