FYi...
The F35'S vertical takeoff and landing (VTOL) fundamental design is nearly three decades old. It is based on the Yak-141 design.
Down to the tail.nozzle that would tilt downwards, to the single engine design, to the twin tail, etc. The obvious similarities in configuration are all there. Except of course the stealth requirement of the JSF competition made neccesary a substantial redesign in the airframe, use of composite material, the gazillion lines of codes, etc.
What Lockheed gained is the knowledge of how the Yak-141's VTOL/STOL system worked. Then they basically improved upon a design which the Soviets couldn't make succesful, reworked what needed reworking, added what the JSF competition requirements made neccesary, and viola!
