In macroscopic , we should ensure that the doctrine of equivalents applys not only in the infringement stage , but also in the whole stage of the patent , including the patent examination , lasting and infringement stage 在宏观适用层面,应该明确等同原则不是仅仅适用于专利侵权的判断阶段,而是应该适用于包括专利审查即专利产生、专利存续与专利侵权的整个阶段。
The application of the doctrine of equivalents can benefit the patentee completely and firmly . however , the misuse of the doctrine of equivalents can also lead to the extended scope of the protection of the patent , which counteracts the technical improvement and the public interest 等同原则与专利权利要求有着密切的联系,在专利司法过程中可以根据等同原则对专利权利要求进行解释,将专利保护范围扩展到专利技术特征的等同范围。
Besides , since the article 17 of the provisions only contains some fundamental principles while the application of these principles are closely related to the detailed technical schemes involved in the cases , it still requires the judge to convict whether the patent infringement is present according to the special situations of the cases 等同原则体现了专利制度中平衡专利权人的利益与社会公众利益的宗旨,在实践中又体现着衡平的特性。针对目前国内对于等同原则的规定过于原则的现状,本文对于等同原则的具体适用提出了一些建议。
Starting from studying the origin of the common law and the modern precedent , the dissertation makes an analysis of the doe from the respect of jurisprudence by making use of the definition of " abstract objects " , then it analyses some problems which maybe exist during applying the doe and puts forward a program to solve these problems 文章从研究等同原则的普通法渊源和现代先例入手，运用知识产权哲学中抽象物的概念对等同原则进行了法哲学分析，接着分析该原则在适用过程中可能存在的问题并提出解决问题的方案。然后阐述了等同原则的具体应用。
Further studies on the doe does good to set the problem of that kind by offering realistic theories for our legislative and judicial circle , and is of great importance to establish the idea of balancing of interests , widen the realm of intellectual property rights , and promote the development of the patent law , even , in a sense , the whole intellectual property jurisprudence 然而，各种各样的专利侵权行为却阻碍着专利法目的的实现，特别是等同侵权行为。深入研究等同原则，可以为我国立法界、司法界处理该类问题提供理论指导，对于拓宽知识产权研究领域、促进专利法乃至整个知识产权法学学科建设也具有重要的意义。
This dissertation makes it clear the application premise of the doe , and based on which expounds the limitations to the whole doctrine of equivalents and all elements rule , then suggests the organic combination of them . meanwhile , the dissertation holds that the subjective standard for evaluating equivalency should be " the average technician pertaining to this field " , the objective standard be " insubstantial difference " , and the time be at the time of infringement . in addition , the dissertation stands for the abolition of the unnecessary appointing rule in consideration of some problems existing in this rule 在阐明等同原则适用前提的基础上分析了整体等同理论和全部技术特征原则的局限性，并建议将两者有机结合起来；同时，主张判定等同的主体标准应是“所属技术领域的普通技术人员” ，客观标准应是“非实质性不同” ，判定等同的时间应以侵权日为准；另外，鉴于多余指定原则存在诸多问题，主张废除该原则。
Although it is not explicitly introduced in the patent law of prc , the doctrine of equivalents is regulated in the form of legal interpretation for the first time as a judicial principle for the determination of patent infringement by the 17th article of several provisions of the supreme people ’ s court on issues concerning applicable laws to the trial of patent controversies ( hereinafter " the provisions " ) published in june 2001 which also set down both the subjective and objective standard of the doctrine of equivalents 等同原则是各国专利侵权判定的一个重要原则。本文从美国、日本、德国以及国际知识产权组织的立法现状和司法判例入手,采用比较分析和案例分析的方法,从等同原则的适用条件、适用方式和对等同原则的限制三个方面对该原则进行了阐述。
