Just visited the US Patent office website and looked at there NSA patents -- thanks to Anonymous for pointing them out. You can use the URL
http://164.195.100.11/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2Fsearch-bool.html&r=0&f=S&l=50&TERM1=%22national+security+agency%22&FIELD1=&co1=AND&TERM2=&FIELD2=&d=pall
As you can see there are some new ones dated June 27:
| 6,081,634 | June 27, 2000 | All-fiber optically-controlled optical switch |
| 6,081,323 | June 27, 2000 | Measurement of Raman gain spectrum in optical fiber |
| 6,080,996 | June 27, 2000 | Unipolar three-terminal resonant-tunneling transistor |
And I've been going crazy trying to figure out why "5,224,756 Integrated child seat for vehicle" is an NSA patent. Can anyone help?
