Can the patentee be changed in the patent application?

Yes, just change the description of the project. I don't know if you have entrusted an agent. If there is, let them handle it. If there is no delegation, you can submit the corresponding description project request yourself. The specific information includes: the filing project change declaration form, which can be downloaded from the website of SASAC, and the inventor's change statement, which means who agrees to change it for whom, and then the applicant's consent is required.
