专利侵权判定中等同原则的适用及体系完善

Application and Perfection of Doctrine of Equivalents in Patent Infringement

等同原则是判断是否存在专利侵权的一项重要准则,在社会实践中专利侵权越来越多地表现为等同侵权。等同原则最终目的是实现公平。我国的立法中一直没有对等同原则作出明确规定。国外专利法中等同原则的适用对我国启示颇多,应借鉴、移植外国研究成果。我国等同原则适用中的判断主体、判定侵权的时间标准以及"等同特征"的判断标准等是在专利侵权判定中适用等同原则应注意的重要问题。等同原则适用体系应在立法上及适用限制等方面进行完善。

Doctrine of equivalents is an important norm to determine patent infringement. In practice, more and more patent infringements appear to be equivalent infringement. The ultimate goal of doctrine of equivalents is to be equal, which has not been regulated in our legislation. We should gain enlightenment from foreign research achievement about the application of the doctrine in foreign patent law. In the application of doctrine of equivalents to determining patent infringement, the subject, time criterion and standard on characteristic of equivalent should be given special attention. The application of equivalents doctrine system should be perfected in legislation and restrictions on it.
