WASHINGTON, Nov. 9 (UPI) -- The U.S. patent office has reportedly granted a patent for an anti-gravity device -- breaking its rule to reject inventions that defy the laws of physics.

The journal Nature said patent 6,960,975 was granted Nov. 1 to Boris Volfson of Huntington, Ind., for a space vehicle propelled by a superconducting shield that alters the curvature of space-time outside the craft in a way that counteracts gravity.
One of the main theoretical arguments against anti-gravity is that it implies the availability of unlimited energy.
"If you design an anti-gravity machine, you've got a perpetual-motion machine," Robert Park of the American Physical Society told Nature.
Park said the action shows patent examiners are being duped by false science.
