Hello, I have a serious doubts in two above references that are actually explaining intellectually protected a general word numeral noun, IMO that could not play the purpose of business name protection without some other public rights infringement, except if the NAME is considered with the all technical specification(classes) as capitalized typing and use that is making sort of extraordinary form(of general use words) and applicable as intellectual excellence/exception and protected.
As I've suggested in my previous post, regulations are improving over time globally, mostly in better formal determinations, and there could be that example case provided above would not stand on some arbitrages in present time.

So domain names as commercial service/product with such huge commercial importance should not be subject of confiscation/taking over possession, as those protection conduct are more up the license holders(pro-active business actions) and regulatory - the registrars, prior entrepreneurship "advantage" arise at the new end users.
