Doesn't Hyperion has lawyers that belong or work closely with them ? If so that should be no problem.
I find it unbelievable that the "shell game" has even one more round to it! Didn't knew that one...
Taking this into account the argument from Hyperion that they didn't knew Itec was going to give the IP back to KMOS seems a valid one, still I find it unbelievable that they signed a contract with them, hope that doesn't invalidate the 1st one...
