I have written a food blog since March 2010 and I own the web domain with the blog's name. About a month ago, a man contacted me with some questions about my blog and I politely answered them. The next day, he filed for a trademark with my blog name. (He also tried to buy my domain but I rejected his offer.) His trademark hasn't been approved yet. If I apply for a trademark with the same name now, will I be able to beat him? I know for sure that I have been using the name longer. Will that give me some sort of precedence? Does it make any difference that at the bottom of my blog it says "©2010 [My name]. All Rights Reserved"?
