How many people can apply for a patent at most?

Legal analysis: there is no limit to the number of applicants. If there are multiple applicants, it means that the patent application right belongs to all applicants, and all applicants enjoy equal rights. After the patent is granted, all applicants will become patentees. When the patent application right or patent right is disposed of, all obligees need to make the same decision, and no obligee is indispensable.

Legal basis: Article 26 of the Patent Law of People's Republic of China (PRC), when applying for a patent for invention or utility model, a request, specification, abstract, patent right and other documents shall be submitted. The request shall specify the name of the invention or utility model, the name of the inventor, the name and address of the applicant and other matters.
