Anyone can sue anyone for anything. In the IP field once something gets widely used it "In the Public Domain" it has lost the ability to receive IP protections. Wide use without appropriate permissions can cause loss of IP protections.It's something that you'd have to keep an eye on, at least if you grow. If you use another systems curriculum, and in the future they set up IP protections, they could potentially sue you afterwards. .
