I registered my domain name in Feb 2011. I have been using my domain name as my business name. I just checked trademarks, and there is a company that registered the name in March of 2011. It's not the same exact name, it is ONE letter of difference. Like "Apple" and "Apples".
Does the fact that I was using the name before them count for anything? I would think that since they registered it, I am going to have to change my name. Any help?
