It doesn't seem to have been examined yet.
Only a single inventor is listed, Salvatore Pais[0]. He's also listed as inventor for a "Laser augmented turbojet propulsion system", "Craft using an inertial mass reduction device", "high frequency gravitational wave generator" (which was granted) and "piezoelectricity-induced room temperature superconductor".
All of which would be massive technological breakthroughs. Meaning he's either the 21st century's most brilliant physicist or a crank.
