Ohio State University falls short of the other Big Ten schools in making money from research. The university in Columbus spent $934 million on research in fiscal 2012 - the fourth-largest amount among the dozen Big Ten universities. But Ohio State again came in last place for licensing income with $2.2 million. That's according to an annual listing by the Association of Technology Managers. For a fifth year, Northwestern University tops the Big Ten and all other colleges with more than $122 million from inventions. Among Ohio schools, Ohio University in Athens earned $9.4 million - more than four times as much as Ohio State. Ohio State officials said they're working hard at turning research into commercial products, but it takes time.
