【摘要】 近年来，随着我国加入WTO后知识产权法制观念日渐深入人心，专利侵权纠纷案件在数量上呈现出一种逐渐增多的趋势，并且具有涉外因素的专利侵权纠纷案件也呈上升态势。在专利侵权判定的理论研究和司法实践中，等同原则的适用问题已经成为倍受关注的一大热点和难点问题。作者通过对传统理论中有关专利侵权判定的几个原则的回顾，在考察等同原则在其发源地美国的演进历史，以及日本在其早期和现在的专利侵权判定实务中对等同原则的态度前后变化后，作者发现：即便是在专利制度相对比较完善的国家，在专利侵权判定中对等同原则的适用也并非毫无限制，相反，从目前情况来看，对其加以更多的限制似乎已经是一种较为趋同的适用理念。为此，作者结合等同原则在我国的理论发展和实践应用的具体情况，并在简单分析禁止反悔原则和自由公知技术抗辩原则对于等同原则的规制作用的基础上，着重分析了方法发明专利与产品发明专利和实用新型专利，其中尤其是产品发明专利的不同特征，并结合自己代理的一起方法发明专利侵权纠纷案件，讨论了在方法发明专利侵权判定中对等同原则的适用规制问题。作者认为，由于方法发明专利有着不同于产品发明专利的特征，因此在方法发明专利侵权判定中必须对等同原则的适用予以适度规制，尤其当被控侵权方法与专利方法存在实质性差异时，不应适用等同原则。更多还原

【Abstract】 In recent years, after China joined WTO the legal system idea of intellectual property right sink deep into the public day after day, the cases of the patent infringement presents a kind of trend which increases gradually on the amount,and the cases of the patent infringement which have foreign factors show that trend too. In the fundamental research and the judicial practice of the determination of the patent right infringement cases, the question of how to make the doctrine of equivalent suitable have already became a hot and difficult subject which was paid more attention. The Author through to review several principles of patent right infringement determination in traditional theory, after investigated the evolution history of doctrine of equivalent in US where its cradle is, as well as in early and recently times ,the changes of the present patent right infringement determination practice in Japan. The author discovered: Even if in the patent system quite perfect country which compares to the others ,the limit of the suitability of doctrine of equivalent in patent right infringement determination is existent,on the contrary, from the present situation, performed more limits to it as if was one kind of similar suitability idea. Therefore, the author unifies the doctrine of equivalent in our country’s theory development and the special details of practice application,and on the foundation of doing simply analysis to what is function while the estoppel principle and the debating principle for free public patented technology effect the doctrine of equivalent will be,the auther analyzed emphatically the differences characteristic between the method patent for an invention and the product patent for an invention and the utility model especially the second one’s, and integrated the opinion of author’s own in order to discusse the question that is the method invention patent right infringement the doctrine of equivalent suitable rules and regulations in the patent tort determination. The author believed, because the method patent for an invention has differences with the product patent for an invention characteristic, there must has the doctrine of equivalent be suitable the moderate rules and regulations in the method invention patent right infringement determination, especially when there are differences between the method of tort and the patent method have been accused, should not be suitable the doctrine of equivalent.更多还原
