I worked in very technical engineering software company and they were super paranoid about their special sauce IP of a product that did analysis of a certain type of data, without being able to see that all the pieces of that special sauce were actually just functions from SciPy strung together and which you could look up in a textbook. Don't get me wrong, you need the right background to understand it and that's not trivial, but if you got someone from the right area you could replicate it pretty easily.
