A trademark is a type of intellectual property that consists of a word, phrase, symbol, design, or combination thereof that identifies a product or service from a particular source and distinguishes it from others. Trademarks also extend to non-traditional marks like drawings, symbols, 3D shapes like product designs or packaging, sounds, scents, or specific colors used to create a unique identity. For example, Pepsi is a registered trademark associated with soft drinks, and the distinctive shape of the Coca-Cola bottle is a registered trademark protecting Coca-Cola's packaging design.
