从表面上看,强制许可似乎与知识产权制度对其所有人自由交易的保护原则存在一定的冲突,但是,从深的层面来看,这却与知识产权制度追求社会公共利益的根本目的一致。本文介绍了强制许可的基本概念及其发生机理,并分别从国际法和各国国内法两个角度对之进行了比较性的研究。 On the face of it, compulsory licensing seems to conflict with the principle that the system of intellectual property protects the free trade of its owners. However, on the deeper level, this is in line with the fundamental purpose of the system of intellectual property in pursuing social and public interests. This paper introduces the basic concept and mechanism of compulsory license, and makes a comparative study of it both from international law and domestic law.
