Abstract: There is a fundamental difference between the “goal orientation” of indirect infringement of intellectual property and the “meaning orientation” of multiple tortfeasors. Since the indirect infringement of intellectual property could not be replaced by multiple tortfeasors， it is necessary to enact the legalization of indirect infringement of intellectual property. Although there are strengths in Chinas legalization of indirect infringement of intellectual property， weaknesses do exist as a whole. The rules of indirect infringement of intellectual property should be set up respectively in the slip laws of intellectual property， the rules of indirect infringement of intellectual property should be categorized and systematized， and the indirect infringement system of intellectual property and multiple tortfeasors should be coordinated so as to perfect the legalization of indirect infringement of intellectual property in China.

Key words: intellectual property, indirect infringement, direct infringement, multiple tortfeasor, joint infringement
