Trademark infringement analysis asks whether one party’s use of a mark is likely to confuse consumers about the source of goods or services. This lesson explains the role of consumer confusion, the factors courts consider, and why marks are compared as a whole rather than word by word or feature by feature.
Trademarks help consumers distinguish the source of products and services. They also help businesses protect the quality and reputation associated with their goods. By helping consumers identify a source and avoid mistaken associations, trademarks support trust and orderly competition in the marketplace.
