What a Trademark Is and Why It Matters

This lesson introduces the core purpose of trademark law: helping customers identify the source of goods or services and helping businesses protect the names, logos, slogans, and other brand signals that customers rely on.

Learners will distinguish trademarks from general business names, domain names, copyrights, and patents; understand why trademark rights are tied to specific goods or services; and see why early trademark thinking can prevent costly rebranding, marketplace confusion, and weak brand protection.
