Hi. Here is the info I used. It includes some NC info but it should be a place to start and get info for everywhere I believe. I hope this helps. If I come across something more I will post it to you too.
I do know you go to the uspto web site for sure and type in your name and see if it says anything about it.

You might wish to then consult a patent and trademark attorney. Here is USPTO directory of Patent Attorneys and Agents registered to practice in the state of North Carolina.
