Infringement of intellectual property rights has basically the same legal nature as general civil tort, and of course it should also have basically similar legal consequences. However, because the nature of intellectual property and the basic characteristics of intellectual property infringement are different from general civil rights and infringements, the manifestations of intellectual property infringement are also different from general civil infringements. The intangible nature of the object of intellectual property rights is the essential feature that distinguishes it from property ownership. Its object is a kind of intangible spiritual wealth, which has no material form, no space, and its possession is not real and concrete. Moreover, compared with other property rights (especially ownership), the existence of intellectual property rights has its unique characteristics of exclusivity, regional effectiveness and time limit. Because of these properties and characteristics of intellectual property rights, the infringement of intellectual property rights is basically twofold, that is, it infringes on the property rights of the intellectual property owner and the creditor's rights of the intellectual property owner; There are both violations of independent property rights (personal rights of works) and single creditor's rights (trade secret rights); There are both intentional infringement and unintentional infringement (neighboring rights); The occurrence of an act is infringement, and the result of the act is also infringement. This duality of intellectual property infringement determines the duality of tort liability principle.
