Patented inventions are everywhere, from the post-it notes on your desk to the windshield wipers on your car. This year, Denver businesswoman Sirena Rolfe snagged one of the more than 10 million patents issued in the United States. Her invention is a hood to protect your hairdo when it's raining. Rolfe is proof that even in this high-tech world, a person with a good idea can still get a patent. But it’s not always easy. We talk to Rolfe about her journey and with University of Denver law school professor Bernard Chao about the challenges of getting a patent. It’s part of our series, Disruptors, which explores entrepreneurship in Colorado.
