Can we Trademark/Servicemark
My organization will be involved in co-hosting a model rocket launch with another group that is not incorporated nor a partnership, but is really a ''model rocket club''.They are a charted section of a national non-profit association. They claim their club has a TM on the name of the event. Can they common law trademark the event name - or anything for that matter since they do not appear to be a legal entity on their own? May the national assoc. trademark the name? In either case would the use of SM be more appropriate since this event is a recreational service? Could my organization be liable if they claim a trademark?
