Like I said it was joint only in the sense it was signed by someone from Coopervision just in case something were to happen, that way COO could benefit from so called "licencing" agreement which would be null and void if the patent was granted anyway because they would own part, some, a bit of it going foreward. It will not because it was only a novelty to begin with. The contest COO was running was for anyone with an idea, if that idea could make it in the lab, then yes something may have come from it but as it was nothing did. EPGL did not even get an honorable mention from COO for their so called development. If this company was even close this tech would be help up by the military for years. It is too early for this kinda stuff to get to the public.
