论专利权与留置权之冲突

Study of conflict between patent right and lien

在加工承揽合同中,承揽人在含有专利权的产品上行使留置权时,当事人往往会主张留置权与留置物上存在之专利权产生权利冲突,阻碍留置权的行使。这一冲突的提出似乎使知识产权权利冲突的协调机制更为复杂,文章从专利权性质及权利人商业利益的角度,利用实证的方法,对优先权与专利技术默示许可的理论进行分析与论证,否定了此种情形下专利权与留置权权利冲突之存在。

The parties may claim that there is conflict between lien and patent right against lienor's exercising lien on the products containing patent right.It seems that this makes the coordinated system of intellectual property(IP) rights conflict more complex.This paper analyzes the priority rule and implying license theory,negates the existence of the conflict between liens and patent right.
