I guess the point GP was making about Aerodynamics is that you can't exactly patent the bernoulli's theorem. If you wish to build an Airplane some things are going to look quite similar to how others build it. The same goes with rockets too. May be F1 cars etc. Things like that. At some point your design will look as physics wants it.
