What's the difference between patent application right and patent right?

(1) The right to apply for a patent refers to the right of an inventor to request the patent office to grant him a patent right for his invention and creation. Patent right refers to the exclusive right granted by the patent office to the applicant at his request when the invention meets the conditions stipulated in the patent law. (2) filing a patent application is a necessary procedure and prerequisite for obtaining a patent right. Only when you have the legal right to apply for an invention can you get the corresponding patent right. But having the right to apply for a patent does not necessarily mean obtaining a patent right. Where an invention-creation for which a patent is applied does not meet the conditions for granting a patent, the applicant for a patent cannot be converted into a patentee because the invention-creation has not been granted a patent. There may be many patent applicants, but only one person may become the patentee.
