I see the other guys here has given you tech and legal hints,
so I'll limit myself to legal hints and politics.

..if you give, sell, loan etc him that prototype, and he is not part 
of your business or household etc, you will want check up on the 
distribution language in the GPL and the other relevant licenses.

..the primary idea behind the patent legislation, is help you 
learn from the patented ideas, how they works etc, etc, so you 
can find even better ways to do what the patents claims, and 
patent your own improvements, if they are good enough, they 
"improve the arts."

..about the only thing you can not do with something that's 
patented, is sell etc distribute the patented items, the other 
"secondary" point with patents is reward the innovator with a 
20 year sales monopoly so he can recover his R&D costs and earn 
an honest decent profit.
