The term "trademark" is typically used to refer to any type of mark, name, design, logo, or slogan that can adequately identify a product or service and that can be registered with the USPTO. The two primary types of marks that can be registered with the USPTO are:
Trademarks - used by their owners to identify goods, that is, physical commodities, which may be natural, manufactured, or produced, and which are sold or otherwise transported or distributed via interstate or international commerce.
Service marks - used by their owners to identify services, that is, intangible activities, which are performed by one person for the benefit of a person or persons other than himself, either for pay or otherwise and offered in interstate or international commerce.
