Patent Roll Call, Fall 2015

A good invention can set a new standard in its field, redefine what’s possible and even change lives across the world. But before any of that can happen, most inventions require patenting. Patents protect innovations and help their creators bring them beyond the walls of the laboratory to benefit society at large.

Congratulations to these University of Minnesota researchers who were recently awarded patents for their discoveries. To learn more about reporting an invention, contact the Office for Technology Commercialization at 612-624-0550 or umotc@umn.edu.
