he doesn't have a background in programming so i strongly doubt it.
From his Wikipedia:
Keiser invented "Virtual Specialist Technology", a software system used by the Hollywood Stock Exchange.
He also said himself that he holds some software patents on virtual currencies:

I am the only one in the world who has four patents on virtual currencies ...
