Legal rights to University project?
patio11: When I turned a university project into an internship with them, we made it very explicit to everyone concerned exactly when the project started becoming "something other than class work" and what consequences that had for all parties involved.I tend to think that 999 out of 1,000 legal worries people have are groundless.  Want to sleep better at night?  Draw up a simple letter of understanding between you and the University and ask for your professor to sign it.  After doing so, take it to the university counsel or IP office (major research institutions have one) and ask them to sign off on it.  If they do, congratulations.  If they don't, consider your options.
