Company A has URL of " Books USA . com " Company B has URL of " Chapbook . com " so both URL are completely different . Issue is when you go to Company B website it says Welcome to " Cheap Books USA " - meaning that they are selling cheap books inside of USA Can company A who has copy right of this " Books USA . com " including the dot com at the end ; telling the company B that you are using a part of my copy right name in your website which is " Books USA " Again , the URL of both website are different and website designs are very different . The issue is on word " USA " Isn't the word of " USA " is too common ? Does company A have a claim here ? What you gentlemen think of this case where there is common used word ? especially on the world of INTERNET .
