OK so Im looking to trademark to protect my self from another company with the same name, but not the proper credentials. They are not in my area but are in the state. I dont intend to do business out of state. I have researched trademarks some, but havent really got the answers I seek. I would like to protect the name and logo. I gather the name is a servicemark and the logo is a trademark. If I stay in state does the federal TM do anything for me. Also what does the state TM do for me that the federal doesnt. Basically I want to protect what we have and possible force the other guy to change. Lets here what everyone has to say.
