Bugging your profs will only show that you couldn't be bothered reading up on your university's by-laws and regulations. It could result in a down-mark.

It is really good to be confident, but in reality your undergrad work might be a lot less brilliant than you believe it to be. Some universities will actually co-venture with you if your work is patentable, etc and although you end up sharing revenue, they might foot the up-front legal costs (which can be rather substantial) - again, research what applies in your particular case.

Good Luck with your project and subsequent ventures.
