This presentation introduces trademarks and their importance. A trademark is any sign that identifies goods from one enterprise and distinguishes them from competitors. Trademarks provide legal protection against fake products, allow customers to easily identify brands, and create goodwill. Essential features of trademarks include being distinctive, easy to pronounce, not descriptive, and satisfying registration requirements. There are different types of trademarks including word marks featuring words or letters, device marks representing logos or designs, service marks identifying services, and collective marks used by groups.
