【摘要】 等同原则是美国法院在专利侵权审判实践中提出来的一项重要的司法原则，其在美国已有近二百年的历史，并且已形成了一套较为成熟、完善的理论体系。在美国的影响下，等同原则已在全球范围内被广泛接受。我国最高人民法院也于2001年对该原则作出了原则性的规定。等同原则的适用虽然有效地维护了专利权人的利益，但如适用不当则又可能会破坏权利要求界定发明和告示公众的双重功能，使专利侵权判定的结果带有不确定性并最终侵害以被告为代表的公众利益。因此，为了使等同原则的适用更加客观、确定、公正、合理，能够有效地平衡专利权人与公众之间的利益，在适用等同原则时，除了从内部的等同判定标准、判定方法等方面进行规范外，还应从外部通过禁止反悔原则和公知技术抗辩原则进行严格的限制。更多还原

【Abstract】 The doctrine of equivalents is an important judicial principle which was put forward by American Court in the practice of Patent Infringement. It has a history of nearly 200 years and it has grown into a rather perfect theory system. The doctrine of equivalents has being accepted word-widely under the influence of America. The Supreme Court of China set some principled regulations over it in 2001, too. Though its application can protect the patentee’s interest effectively, its improper application can spoil the double functions, defining invention and informing public, of patent claim. Thus, there will be something uncertain with the result of Patent Infringement judge and finally infringe upon the public interest represented by defendant. Therefore, in order to apply the doctrine of equivalents objectively, definitely, fairly and reasonably and to make a perfect balance between the patentee’s interest and the public’s interest, when applying it, we should not only limit strictly from the inner aspect, such as its standard, method, etc, but from its outer aspect such as Estoppel, Prior Art Defense.更多还原
