Which marks are specifically protected under the Lanham Act of 1946?

The Lanham Act of 1946 is a key piece of legislation in the United States that governs trademarks and their protection. It specifically protects distinctive marks that identify the source of goods or services. The correct choice encompasses trademarks, service marks, certification marks, collective marks, and trade dress, all of which are covered under the Act.

Trademarks and service marks serve to distinguish the goods and services of one provider from those of others, while certification marks indicate that goods or services meet certain standards. Collective marks help identify members of a collective organization, and trade dress refers to the visual appearance of a product or its packaging that signifies the source of the product to consumers.

The other options include various intellectual property rights that fall outside the specific scope of the Lanham Act. For instance, patents and trade secrets are classified under different laws, and copyrights protect original works of authorship rather than marks identifying goods or services. Trade names and economic rights are also not directly covered by the Lanham Act in the same manner as the types of marks mentioned in the correct choice. Thus, the marks specifically protected under the Lanham Act are exactly as outlined in the chosen option.
