The principle of confusion in intellectual property law, also known as the principle of analogy or the principle of induced infringement, refers to a legal principle in trademark law, which refers to "the use of similar or similar goods or services with Marks that are identical or similar to a registered trademark and are likely to cause confusion among consumers shall not be registered and used.”

It refers to situations where similar or identical trademarks appear on similar or similar goods, which can easily cause confusion among consumers, leading to misidentification of goods. The principle of confusion comprehensively considers aspects such as vision, accent, and meaning, and conducts an overall evaluation and judgment on trademarks to protect the rights and interests of trademarks, avoid consumer confusion, and maintain market order and fair competition.
