As an incoming Ph.D. student I was asked to sign an intellectual property assignment agreement in addition to an employment contract as a condition for receiving a tuition reduction and a stipend. The wording was rather vague, and contained 'legalese'. I have no experience with this. So, I do not know anything about it, and I do not know if the "agreement" I signed contains anything abnormal, because of the way it was written.
Is this normal practice?
If so, what is contained in a standard intellectual property agreement?
