What is the difference between a trademark and a service mark?

A trademark is a word, phrase, symbol or logo that is used to brand, identify, and distinguish a product. A service mark (or servicemark) is a word, phrase, symbol or logo that is used to brand, identify, and distinguish a service. The TM and SM designations are placed with trademarks and service marks to show that the owner has started the registration process. Both trademarks and service marks serve the purpose of protecting the brand and reputation of the mark holder and help prevent others from using the same or similar marks for similar products or services. The legal requirements and processes for obtaining trademark or service mark protection are similar, However, the registration process may vary slightly for trademarks and service marks.
