What is the difference between a Trade Name, Trademark, and a Service Mark?
Each of these terms does mean something different and while there are gray areas, it is easiest to see trade names as relating to businesses or entities and trademarks and service marks as relating to the products of businesses or entities. If your product is goods, you would be applying for a trademark. If your product is a service, you would be applying for a service mark. For example, DCCA, Inc., a corporation, or DCCA Co., a partnership, has registered a trade name “DCCA Manufacturing Co.” The corporation or partnership might also apply for registrations for its “DCCA Widgets” (trademark) and for its “DCCA Widget Maintenance” (probably a service mark).
