My patent certificate has not been issued yet. Someone wants to add a name to it, and the patent right belongs to me. Will it affect me?

Be careful about this! According to the provisions of China's patent law and its detailed rules for implementation, unlike other economic contracts, the agreement on patent transfer and implementation license must be filed with the state patent administration department before it can take effect. Whoever adds his name to the patent certificate is one of the patentees. The agreement you signed privately to give up the patent right is only valid after being filed by the state patent administration department.
