It's funny how these things work. They don't even specify the wavelength of the LEDs used, instead preferring to patent any wavelength imaginable. But obviously not all of them will work. Why was this allowed in a patent? How is this a valid description of what they built? |

If you built it with wavelengths that worked, it'd be covered by the patent. If you built it with wavelengths that didn't work, it'd probably be useless.
