When the patentee is a natural person, once the natural person dies, his patent right will be transferred to the person who has the right of inheritance according to the provisions of the inheritance law. If the patentee is a legal person, once it is merged or dissolved, its patent right will be transferred to the legal person who enjoys the right of inheritance according to law.
According to the patent law, the change of patent subject is a necessary legal act. That is, it must be performed through legal procedures and must be completed before it can take effect.
Therefore, once the patentee dies or disappears, the successor or assignee of the patent right shall go to the patent office for patent inheritance or inheritance procedures. That is, when the patentee is a natural person, the death certificate of the patentee must be submitted, as well as the certificates that can prove the legal inheritance relationship between the patentee and the patentee, such as the certificate of parent-child relationship and the certificate of husband-wife relationship. When the patentee is a legal person, it must submit the certificate of dissolution or merger of the legal person, or the certificate of the superior competent department of the enterprise that requests to inherit the patent right, etc. After examination and approval by the Patent Office, the patentee may go through the formalities of changing the description items, inherit or inherit the patent right, and the Patent Office shall register and announce it.
