I think he was planning on eventually sharing the arc reactor tech, since he mentioned it to Obie as an alternative. But he got all side tracked with THE MISSION and the flying robot suit. I think once things calmed down he'd get back to it.

He seems to have got pretty paranoid right off the bat about sharing his tech - from day one of his return he's not keeping anything on the company servers - and it's HIS company, and he has no reason to suspect Obie yet.
