A more thorough explanation:

Definition: A famous trademark is a well-known brand or logo that is widely recognized by the public and has gained a high level of reputation and goodwill. It is protected under trademark law and is often associated with quality, reliability, and trustworthiness.

Example: Coca-Cola is a famous trademark that is recognized all over the world. The distinctive red and white logo and the unique taste of the soda have made it a household name. Another example is Nike, which is known for its "swoosh" logo and high-quality athletic shoes and apparel.

These examples illustrate how a famous trademark can become a valuable asset for a company. By building a strong brand identity and reputation, companies can differentiate themselves from their competitors and create a loyal customer base.
