ABSTRACT

When most people think of a trademark, they think of logos for products, like the distinctive “3d” look of Superman’s name1 (Superman® comic books,2 Superman® brand candy3) or services (Superman Ride of Steel®4). This is fairly accurate, since trademarks and service marks are used: (1) to identify and distinguish a trademark owner’s goods and services from those sold by others; and (2) to identify for consumers the source of those goods and services.
