Does the patent pledge need to be reported to the State Information Bureau?

According to Article 227 of the Property Law, a written contract shall be concluded for the pledge of patent rights. The patent pledge is established when the competent department handles the pledge registration. Based on the provisions of this property law, if the parties do not register the patent pledge, the pledgee's priority right of compensation based on the security interest will not be guaranteed by law, so once the patent pledge relationship based on the main debt contract relationship is established, the pledgee must register the pledge with the pledger.
