Certainly not one Ryan Thomas Grace who has applied for a patent for the above captioned invention in the USPTO. Here's the abstract:
The purpose of this invention is to provide an improved method of proposing marriage to an individual. The method of proposing to an individual generally comprising the steps of meeting the individual; exchanging names with the individual; dating the individual (not necessary); drafting a government document having a proposal to marry the individual incorporated therein; and showing the government document to the individual. The government document may be a patent application. The patent application may claim the method by which the proposor will make a marriage proposal to the individual. The proposor could then use the method claimed in the patent application to propose to the individual. The patent application could be the actual marriage proposal.Here's the application.
It is not known whether this invention passes the "utility" test. However, the putative inventor is apparently now gainfully employed at the well established firm that filed the application.
Good luck, Ryan!
