The development of trademark's advertising function is the basis of the trademark dilution theory. Dilution differs from the traditional confusion infringement in that it does not lead to confusion of goods source on the part of consumers, but whittle away the uniqueness of a mark or harm its reputation. Therefore, those trademarks that have acquired considerable reputation deserve to be protected from dilution. However, trademark right is no more than a quasi-property right, overprotection will change its nature and eventually hinder free competition. So the scope of anti-dilution should be limited. |
