The telescopes NASA runs at educational institutions are presumably legit. The one patent they demonstrated in the link is related to image stabilization technology in telescopes to study solar flares.
They are only releasing 40 patents to the public. Surely the world's leading space agency, creator of many propulsion technologies, communication technologies, life support technologies, robotics technologies, with space ships which have sent men to the moon and robots to mars would have more than 40 patents.
