How many patent inventors can there be?

Without restrictions, Article 8 of the Patent Law stipulates: Unless otherwise agreed, the right to apply for a patent belongs to the invention-creation jointly completed by two or more units or individuals, or the invention-creation entrusted by other units or individuals; After the application is approved, the applicant unit or individual shall be the patentee. Therefore, there is no limit to the number of patentees and inventors. All patentees have equal rights. Of course, if there is an agreement between the obligees, they can also follow it.
