Toby2, that UNDT PR was simply not true...kinda; The headline said that UNDT received the Patent, later on it says Caltech got it which was true; http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20090043117_2009044006.pdf By the time that PR came out Caltech was pretty much done with UNDT. Please read these especially the last 10-Q and 10-K; http://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0000763950&owner=exclude&count=40 Good luck.
