Person A filed a patent in his name only, the patent is pending and was recently declined with the option to re-submit with amendments. It was resubmitted and therefore still pending. Person B, who is not names on the patent, was the person who actually created the very first prototype of the patent, on the own time and not at the request of Person A. However, the idea was based on the teaching skills of Person A. Does Person B have any claim or consideration and can he challenge the patent to at least have his name included?
