商标淡化是针对驰名商标的特殊保护而言的，所谓“商标淡化”，就是指对商标显著性的削弱，对商标标记功能的侵害。在普通法系国家，如美国，淡化（Ｄｉｌｕｔｉｏｎ）是商标侵权的一种形式，与一般的在同类或相似商品或服务上使用相同或相似商标、及不正当竞争等，同属商标权 Trademark desalination is aiming at the special protection of well-known trademarks. The so-called “trademark dilution” refers to the weakening of the distinctiveness of trademarks and the infringement of the functions of trademark labeling. In common law countries, such as the United States, Dilution is a form of trademark infringement that is the same as a trademark in the same way that similar or similar trademarks are used for similar or similar goods or services, and unfair competition.
