I wanted to have our inventions to get to the point where they could really help people, and it’s very difficult, because it takes a lot of money to do that. So I began writing patents on our work, and today we’ve licensed or sublicensed these patents to actually 250 different companies. Actually, with my students, we even started about 25 companies. I should add that when I first started doing this as a professor in the early ’80s, most academic scientists looked down upon it. They said professors shouldn’t do things like that. But today these companies have made all kinds of products that treat patients — and I’ll mention some of this — with cancer, heart disease, and many other sicknesses, they’ve created tens of thousands of jobs.
