The question
I began using a word and logo with that word in early 2019. I did not register it yet because I was building momentum with it. I put it in my website, documents, and used it other places. I have witnesses and the documents to show I've been using it since 2019. About 18 months later someone registered the word with the trademark office when I began preparing to register it. They registered it in my area/section. They have done nothing with it the six months they have had it. I have sent them a letter, registered mail, telling them I've had a common law trademark since early 2019 and ask for their cooperation. My question is do I have a case for this trademark with my common law trademark? Can I force them to assign the federal trademark over to me? I'm even willing to reimburse the trademark fees. I'm in Las Vegas but this person is in Stamford CT
