It's up to the trademark owner to enforce their exclusive right to the use of their trademark. If you have the trademark 'Orange Designer' registered in, say, Malaysia, then the only thing stopping someone registering it in, say, the USA is you, the trademark owner.
I'm not sure of the correct procedures to follow but it can end up being expensive, even if you win.
A recent example was on this forum was a user was selling a cheap knock off of a Saleae USB logic analyser, labelled as a Saleae branded item. Saleae say that this has happened a few times and while they are flattered, they send a cease and desist letter to the offender hoping this is enough. As I said, it's expensive to enforce a trademark/brandname.
