What is the takeaway ‘product’ of a course?  Knowledge? In all its forms?

If I furiously scribble notes in a lecture hall, and capture it perfectly, who owns the rights to those notes?  Are they somehow ‘protected’, or is sharing one’s knowledge with students a ‘gift to the world’.

If the instructor delivers this knowledge in ‘digital’ format, does the ‘content’ remain the intellectual property of the instructor?  Or, does it become part of what the student bought when he paid for the course?

Is it any different than if they had  scribbled their own notes?

I have recent experience with this very dilemma from both sides of the desk: instructor colleagues say ‘It’s my property’;  students say ‘But the whole reason I took this course was to acquire, and then benefit from, this very knowledge. How can I benefit if I cannot reuse it?’

When we PAY for learning, does a transfer of ownership take place?

Or, is this simply an ‘analog’ versus ‘digital’ conundrum, unrelated to intellectual property rights?

What say ye?
