This makes sense from a business standpoint, but from the outset it would seem that nobody then would be able to found startup companies unless the concept or implementation they came up with was entirely out of the line of what their prior company was doing. How often does that happen? Say you are working for a proteomics company on their own line but while working there you conceive of a wonderful new proteomics platform that would speed up things and make them more accurate. If you leave the company to start this new platform on your own, what's to prevent them from suing you? Or let's say you're working in the immunology division and are working on HCV vaccines for company XYZ, you obviously have learned a lot about vaccine design there, if you were to found a startup that works on a brilliant new dengue vaccine and succeed with your primate models (not that there's money there, or that that's exactly feasible for an early startup), how would you be able to prove that your dengue vaccine does not derive in any way from the prior company?
