Maybe I’m being too idealistic about this?[/quote:8b82128f50]
What you think you signed isn’t the issue. Whose resources you used or how fair you think this is isn’t the issue. The only issue is if you signed an assignment or not. IP rights can only be given away via a written assignment of rights (there is no such thing as a verbal contract for IP assignment).
You need to know what you signed – or to be precise what the school can prove you signed ;). The only way to know that is to go to the school and ask for a copy of everything you signed. Tell them your flatmate eat beans off your paperwork because they couldn’t be bothered to wash up and you need a new copy. Once you actually know one way or the other then start to worry about it or not as the case may be.
