Gracie : I am not educated as a lawyer however I have had quite a bit of experience with issues related to logos , trade- styles / trademarks , and the like .
It has been my experience that if a legal entity does not " defend " / "enforce" it`s rights to sole use of it`s various trade-marks , slogans et al after a while it will lose legal claim to exclusivness .
I believe that these rights and requirements to enforce the sole rights to unique trade-styles come under the heading of what is known as " The Uniform Commercial Code ".
But then again what do I know ? There are no doubt many more experts on this site than me .
