Yes they can, all the patent is is for a process, you don't need the inventor to use the patent, all the info is in the patent details. Zimmerman is not needed and if he was he would not be involved with SSOF.
He is involved with SSOF because he is trying to get his own approval again and doesn't have any money. If he was involved with Stelis he would have no need to raise capital as Stelis would have all the capital he would need and he would be working with them.
