Brand infringement occurs when a company uses a name, logo, or other identifiers that are similar to those of another brand, leading to confusion among consumers. This can happen intentionally or unintentionally, and it often violates trademark laws designed to protect brand identity and reputation. When brand infringement occurs, the original brand owner may take legal action to stop the infringing party. This can include sending cease-and-desist letters or filing lawsuits. Protecting a brand is crucial for maintaining customer trust and ensuring that consumers can easily identify genuine products associated with the brand, such as Nike or Coca-Cola.
