How does trademark differ from copyright?
Copyright protects original works of expression, such as novels, fine and graphic arts, music, phonorecords, photography, software, video, cinema and choreography by preventing people from copying or commercially exploiting them without the copyright owner's permission. But the copyright laws specifically do not protect names, titles or short phrases. That's where trademark law comes in. Trademark protects distinctive words, phrases, logos, symbols, slogans and any other devices used to identify and distinguish products or services in the marketplace.
There are, however, areas where both trademark and copyright law may be used to protect different aspects of the same product. For example, copyright laws may protect the artistic aspects of a graphic or logo used by a business to identify its goods or services, while trademark may protect the graphic or logo from use by others in a confusing manner in the marketplace. Similarly, trademark laws are often used in conjunction with copyright laws to protect advertising copy. The trademark laws protect the product or service name and any slogans used in the advertising, while the copyright laws protect the additional creative written expression contained in the ad.
