For one of the foremost examples of entrepreneurship and tech transfer in the Denver area, look to the University of Colorado School of Medicine’s Department of Ophthalmology. The department has filed for more than 20 patents and spawned six startup companies in five years, with one of those companies expected to send a dry-eye aid to market within 10 months. Department staff has grown from 10 to 50 people in seven years, and a June 28 groundbreaking paves the way for space to grow from 48,000 square feet to 135,000 by fall 2014.
