How many patent inventors can there be?

There is no limit on the number of applicants and inventors for a patent application. Patent inventor refers to a person who has made creative contributions to the substantive characteristics of invention and creation. Inventors can only be natural persons. The inventor or designer mentioned in the patent system only represents the person who has made substantial contributions to this patent. In the process of completing the invention-creation, it is only responsible for organizing the work, providing convenience for the use of material and technical conditions or engaging in other auxiliary work, and does not belong to the inventor or designer. The position of the first inventor is the most important, and the second and third inventors can also enjoy certain preferential policies.
