Final answer:
A trademark offers legal protection for an identifier of a company's goods or services. In the United States, trademarks are protected for 10 years following registration and can be renewed indefinitely every 10 years as long as the mark is actively used.
Step-by-step explanation:
A trademark is a symbol, word, or words legally registered or established by use as representing a company or product. It serves as a unique identifier for goods or services provided by a person or company. Trademark registration gives the owner exclusive rights to use the mark and protects it against unauthorized use by others.
In the United States, when a trademark is registered it initially provides protection for 10 years. After the initial period, the trademark can be renewed indefinitely for successive 10-year periods, provided the mark remains in active use. This system is designed to encourage continued use of the trademark, ensuring that brands maintain their distinctiveness over time.
Trademark rights come into force upon registration and can prevent others from using a similar mark on related goods or services that might cause confusion. This protection is crucial as it safeguards the reputation and goodwill associated with the trademark.
