Here is an interesting item from the U. of Missouri. Mizzou was suing one of its own professors over royalties from a patent invented in University labs. What is not said in the item or the comments is that Universities asserting rights to royalties from patents by their employees is a good way to ensure there won't be any patents coming out of University labs.
