The author in this paper believes the protective scope of intellectual property rights needs to be specially stipulated because of the nonmaterial characteristics of intellectual products. Those stipulations reflect not only the definition but also the limitation of the scope of validity. Infringement of intellectual property rights is an illegal factual conduct, which targets the exclusive right of the owner of intellectual prod}ts and differs from the ordinary torts. Regulating infringement of intellectual property rights, it is necessary to adopt the doctrine of dual liability criterion, i. e. fault liability and presumed fault liability. A multi protective and remedial system including civil, criminal, and administrative law measures should be adopted in the law of intellectual property rights. |
