Michael Jackson did initially patent but did NOT invent anti-gravity shoes.  This idea was used in the Fred Astaire/Betty Hutton 1950 Paramount movie, "Let's Dance."  At the opening of the movie, Betty's character belts out the song, 'Can't Stop Talking,' for a USO show in London, 1944.  Miss Hutton is seen in anti-gravity pumps right before the tears loose dancing with Fred Astaire.
