Can I copy a digital game from a PS3 onto a flashdrive to download it to another PS3?

I know you can transfer Saved Data from one PS3 to another using a Flashdrive(I've done it so when i switch back and forth, i will always have my saves on hand), but can I do the same thing with a digital PS3 game like Minecraft? Help is greatly appreciated, if somone knows how it also greatly appreciated.
P.S. I didn't but the game on my account, an Uncle of mine bought it on his PSN account and was allowed(Due to PSN policy)to add it to one other PS3 for free.
