registration of "InterNIC" related names

[lyndonmaxewell]

Hi, just to inquire, i see that many of internic related names, for example internic DOT ccTLD are registered. Is it worth-it/valued for money to register one of this kind of name if the ccTLD is available? for example internic.us, internic.ca are registered.

I see that many of this registered names are used for providing domain registration services. Is "InterNIC" trademarked?
