Trademarks are basically those symbols, designs, words, colors, or other indicia which tells people the origin of a product or service. For this reason, many people refer to Trademarks as "source identifiers" because they identify the source of those goods or services. Another way to think of Trademark Law is a way to enforce and protect your business goodwill.

There are many types of Trademarks. The most commonly
understood and recognized trademark is the word mark or name mark. Examples include Coca-Cola®, Apple® Computers, and the Los Angeles Dodgers®. You should also note that other trademark rights also extend to those products and services. Coca-Cola® has rights in the colors and stripes which are emblazoned on their products. The Los Angeles Dodgers® have rights in the type of font and design used to compose their mark LA Dodgers®. And Apple® also has rights in the symbol of an apple with a bite in it.
Other lesser known types of trademarks include trade dress, sounds, smells, and colors. When employed appropriately and consistently, these qualities can also act as source identifiers, and accordingly, asTrademarks.
