摘要： 在侵犯著作权案件中，如果被控侵权行为人虽未经著作权人的同意，使用甚至抄袭了受著作权保护的作品或作品的片段，但若情节轻微，未对该作品的正常使用产生任何实质不利的影响，亦未对权利人的权利造成实质性的损害，则应适用“不计琐细原则”，免除行为人的责任，以寻求在权利人利益与著作权法所体现的社会公共利益之间的平衡。

Abstract: Summary In copyright infringement cases，if the alleged infringer uses or even plagiarizes the copyrighted works or parts thereof，which causes no substantially adverse effect on the normal exploitation of the work，nor does it inflict any substantial damages to the right owner，the de minis doctrine should be applied to exempt the liabilities of the defendant and seek the balance of interests between the right owner and the general public embodied by the copyright law．
