Generally business' may not trademark domain names that are of a generic term. It's likely a global principle.
Websites like "lawyers.com" ; " hotels.com " ; " business.com " "travel.com " ..... appear to be unable to obtain trademarks , despite big expensive battles with the authorities. See this example : [chicagobusinesslitigationlawyerblog.com ]
And if you get over this hurdle in one country , there's over 200 jurisdictions world wide to apply to get better protection.
But these folks all appear to trade brilliantly. So why bother trademarking at all. Is trademarking for generic named domains a waste of time , and if it is why bother trademarking e-commerce business anyway?
Any thoughts out there ?
