pledge of rights refers to the form of pledge of specific rights as collateral. However, not all rights can be the subject of rights pledge, but only the property rights with exchange value other than property ownership, such as creditor's rights, equity, trademark rights, patent rights, copyright and other intangible property rights; Rights that have no exchange value cannot be pledged, such as personality rights, identity rights, custody rights and inheritance rights. Because of this, the pledge of rights is stipulated by law. China's "Guarantee Law" stipulates that it includes creditor's rights, equity rights, intellectual property rights, real estate income rights and other rights that can be pledged. The right pledge is set in the same way as the chattel pledge. First, the parties enter into a pledge contract, and then the pledger delivers the right certificate to the pledgee within the time limit stipulated in the pledge contract. There are many similarities between right pledge and chattel pledge, such as the contract of pledge, the scope of pledge guarantee, the rights and obligations of the pledgee, and the way to realize the pledge right.
