What distinguishes a trademark from a patent?

The distinction highlighted in the correct answer focuses on the fundamental functions and protections each term provides in the realm of intellectual property. A trademark serves to identify and distinguish the source of goods or services, enabling consumers to recognize and trust a brand. For example, logos, brand names, and slogans act as trademarks that help identify a company’s products and establish brand loyalty in the marketplace.

In contrast, a patent grants the inventor exclusive rights to make, use, or sell an invention for a defined period, typically 20 years from the filing date. This protection serves to incentivize innovation by allowing inventors to benefit commercially from their creations without the immediate threat of competition.

This definition underscores the different roles that trademarks and patents play within business and legal frameworks, distinguishing their respective protections regarding branding versus invention. The other choices misrepresent or confuse these core characteristics, further reinforcing the validity of this distinction.
