Trademarks
A trademark is used to identify a product. It identifies the source of the good and that helps a customer identify the product so the customer can have an expectation of the quality or other characteristics of the product or service. Trademarks protect. Likewise, the trademark helps build reputation for the entity that sells the goods by allowing the customer to associate the trademark with the goods. Service marks work the same way, but for services instead of goods.
A trademark or service mark can be any words, images, or combination of words and images that you want to identify your product or service. Trademarks and service marks can be black and white, in color, or in grayscale. The more you add to your trademark or service mark, the harder it is to stop someone from using a similar trademark. Less is more in this instance.
