Independent claim number 1.  Three parts.

1. A personal propulsion device, comprising:
a body unit having a center of gravity, wherein the body unit includes a thrust assembly having at least two thrust nozzles located above the center of gravity, the thrust nozzles being pivotally coupled to the body unit;

a delivery conduit in fluid communication With the thrust assembly; and

a base unit in fluid communication With the delivery conduit, the base unit capable of delivering pressurized fluid to the delivery conduit, wherein during operation the body unit is independently movable with respect to the base unit and capable of flight.

Independent claim 14, same parts as claim 1 with nozzle steering.

A personal propulsion device, comprising:
a body unit having a center of gravity, Wherein the body unit includes a thrust assembly having a main conduit and at least two thrust nozzles independently pivotable with respect to each other located above the center of gravity, and wherein the main conduit and the at least two thrust nozzles are independently pivotable about a transverse axis located above the center of gravity of the body unit;

a delivery conduit coupled to the main conduit; and

a base unit in fluid communication with the delivery conduit, the base unit capable of delivering pressurized fluid to the delivery conduit, wherein during operation the body unit is independently movable with respect to the base unit.

All of these details exist in the prior art, NPL.  The European Patent Office rejected the claims based on the previous patents alone. The NACA, NASA, ARMY documents further demonstrate the existence of all aspects claimed in patent 7735772.
