The law should regulate procedure issues but not substantial issues of academic misconducts because people engaging in academic careers and in intellectual production and communication,should have freedom and autonomy in academic fields.If not so, outside factors intervene in the academic freedom. Academic misconduct is not always affiliated with intellectual infringement. This shows that intellectual property law can regulate some kinds of academic misconducts, but intellectual property law is limited in this field. By analyzing the sameness and difference between intellectual integrity and intellectual property, the origin of the limits of law while regulating academic misconducts is given.
