Trademarks () are used to identify goods offered by a business, and the service mark (SM) is used to identify services provided by the business. However, a trademark is generally used to identify both goods and services of a business.
A business can register for both marks. Neither the trademark nor the service mark holds any legal significance unless registered with the USPTO. When a mark is registered, the symbol  is granted to the business, giving it exclusive rights to use the trademark or service mark in the market.
