Just the other day I was out mowing, when lo and behold I see another LCO sporting my business name on his truck word-for-word. So I approach this fellow and point it out to him that I have never seen him before, have been in business since 2002, and have my business name registered with the Secretary of State's office per GA law. He and I were both civil in our discussion and he stated that he honestly did not know that another company (me) already had the name listed, but has no intention of changing the name of his business. Up until now, I have used the common SM (used to use TM) after my logo. I now feel that to prevent the occurrence of my business name being heisted by some newbie that I need to register it with the Feds and thus use the "R" designation. Is this the only action I can take to prevent my trade name from being used elsewhere?
