What is a trademark?

A trademark is specifically defined as a distinctive sign, symbol, logo, word, or phrase that identifies and distinguishes the source of a product or service from others in the marketplace. When registered with the U.S. government, a trademark provides the owner with exclusive rights to its use in connection with the goods or services specified, thereby helping to prevent consumer confusion and protect the brand's reputation.

This registration process also offers legal protections for the trademark, giving the owner the ability to enforce rights against unauthorized use by third parties. Having a registered trademark can significantly enhance the value of a business by securing a brand identity and potentially becoming an important asset for marketing and business strategy.

The other options do not accurately define what a trademark is; they refer to different concepts related to business and finance. A type of financial asset relates to investments and resources; a process for product development refers to the methodologies involved in creating products; and a method of calculating depreciation pertains to accounting practices. Each of these has its own specific context that is distinct from intellectual property rights associated with trademarks.
