Would a patent even of been possible? Would he of made more money than his current bitcoin holdings?
If his interest was in the money, he would have spent some of his bitcoins by now.
Patents are a rent seeking mechanism and they hinder further innovation.
Bitcoin's true growth potential wouldn't have been visible if it was patented.
I totally agree,Satoshi might have forseen this event where many crypto currencies will be battle it out on who can give the best features and so he did not patented it,and besides Satoshi is a very generous guy with a liberal mind like the discoverer of linux..
