Ah good catch! The reason I thought the patent was assigned to the Smart company was because they list it in their Wefunder page[0] (under the heading "Key Accomplishments"). But actually all that's stated on that page is that "multiple patents protect this innovation", they don't actually claim that they have the patents.
I'm still curious how the licensing from NASA works. Do they typically grant a monopoly to certain companies or can multiple competing companies license this technology?
