My company is an S-Corporation in New York and has been in commerce for 2 years now. Someone I know that wanted to sell a domain name to me in September 2013 that is related to my business name because I did not price him higher as he wanted to sell the domain to me, went behind in September 2013 and applied to trademark my corporations name with the USPTO. He got his first office action of his applied mark being denied because of his mark not used in commerce. I have applied this January 2014 to trade mark my business name. What do I do to stop his application because its going to harm by business which already has reputation and customer base. His application will create confusion and conflicts because he is applying to the same line of business as mine just to cause confusion.
