This is not true today and in the past 5-6 years was the same.

There are many Courts in USA and around the world said that an API can't
be patented except under very particular conditions that DC doesn't
meet. So using the same prototypes could be done rewriting the functions
implementation. And also being more conservative you could just need a
little refactoring of function names to change also the API calls.
