First, the information of patent inventor, patent applicant and patentee is changed, including name, title, nationality and address. ;
Secondly, the information of the entrustment relationship between the patent agency and the agent should be changed, including the name, name and address. Under normal circumstances, as long as the actual changes have taken place in the patent specification, the change procedures should be handled in accordance with legal procedures. For some important descriptive matters, such as the change of the address of the patent applicant, it should be handled in time. Otherwise, if the legal time limit is delayed due to the change of address, the patent application may be regarded as withdrawn or the patent right terminated, which may lead to serious legal consequences, and the loss outweighs the gain. Enterprises should pay special attention.
