"they stole idea's from NASA's X-29"

1) The IDEA of making forward swept wing fighters dated a long way back before the X-29, the X-29 was just the first successful one as it could break the sound barrier without having its wings torn off.

2) The X-29 was made by Grumman, NASA just recorder the flight data. So it would be "Grumman's X-29".

3) "The SU-47 was to slow,was terrible in aerodynamic's and it's airframe was very hard to build because of it's wing design" <- The same argument could be made about the X-29.

4) "The SU-47 and SU-37 are ONLY technology demonstraitor's that no longer fly" <- As is/was the X-29.

Your point is so invalid it's carcinogenic.
