No. That is something no one can/should promise you. I will be honest with you during the consultation and at every step of the way about what I think your odds are and whether I think it’s a good idea to apply for your trademark. But even that is not exact prediction. It’s just my educated opinion based on my knowledge of trademark law. No one can guarantee that your trademark will get to the Principal Register. There are too many variables for any mortal to account for. If I don’t think your mark is worth spending the time applying for, I will tell you. I have no interest in wasting your time and money when I know your mark is doomed. It frustrates me when I can’t get your mark registered, so I’m going to be as straight up with you as I can be at every point so that we’re on the same page about your chances.
