What legal protection applies to brand names, mottos, and logos?

Trademark protects brand names, mottos, and logos used to identify and distinguish goods or services from competitors. This prevents others from using similar marks that could confuse consumers about the origin of products or services. Privacy refers to an individual's right to control personal information, not intellectual property. Fair use is a defense against copyright infringement, allowing limited use of copyrighted material without permission for purposes like criticism or commentary, but it doesn't protect brand identifiers themselves. Patent protects inventions and discoveries, granting exclusive rights to make, use, and sell them for a period, which is distinct from brand identification.
