I couldn't give you a list of examples off the top of my head, but I do know that people are aware of this problem and one of the more prominent solutions is to attach a start-up accelerator to the university.
The example I know of is the Innovation Deport in Birmingham, AL (my hometown) being attached to the University of Alabama at Birmingham. The university does a lot of medical research and from what I hear, the Innovation Depot is trying to establish itself as the go-to place for professors to take their patents and provide business/engineering/manufacturing expertise.
