I agree its a sticky slope.

The UH of Hawaii sued 1 student over a 11 million dollar patent dispute.

My understanding was the student did not use school materials or on school time , however he did use his professor as a (question and answer man) - plus his course of study was directly related to his invention. They settled on a 50 , 50 split.

The UH does have pant loads of student patents in the schools name.
