如何确定网络环境下第三方电子商务交易平台的权利和义务尤为重要,本文通过分析美国、欧盟以及我国在这方面的现有做法,指出《侵权责任法》第36条第3款中知道的内涵包括明知和应知,应知的判断不能适用红旗标准,而应用合理注意义务来判断。但为了在保护商标权人的合法权益的同时建立起网络环境下商标侵权责任的避风港,第三方电子商务交易平台合理注意义务应当具有确定性的,它分三个环节并贯穿于整个平台的运营:事前的正确引导、事中的及时删除以及事后全面评估事前和事中的措施是否得到全面的执行并反思其是否达到必要的标准。 How to determine the rights and obligations of the third-party e-commerce trading platform in the network environment is particularly important. By analyzing the current practices of the United States, the European Union and our country in this regard, this paper points out the connotation of Article 36 (3) of the Tort Liability Act Including the knowledge and should know, should be aware of the judgment can not apply the red flag standards, and the application of reasonable care to judge. However, in order to establish a safe haven of trademark infringement liability under the network environment while protecting the legitimate rights and interests of the trademark owner, the reasonable care obligation of the third party e-commerce trading platform should be deterministic. It operates in three phases and runs through the entire platform : Correct guidance in advance, timely removal of the matter and a thorough assessment afterwards whether the measures in advance and in the matter have been fully implemented and whether they have met the necessary standards.
