Is there a difference between the right to apply for a patent and the right to apply for a patent?

I think patent application right is a concept corresponding to patent right, namely: "patent application right" and "patent right". Since it has not been authorized yet, it can only be called patent application right, not patent right. ;Here "patent application" should be a noun.

The right to apply for a patent refers to the right to file a patent application for an invention-creation after it is made. The right to apply for a patent refers to the right that the applicant has over the "patent application" after filing an application with the Patent Office, that is, the ownership of the patent application.
