Dr. Sri Balasubramanian, Biomed Students, and 'The Story of No. 11099089' About Their Patented Portable Dynamometer Are Featured in Drexel Magazine

July 12, 2022

It can take inventors years to receive an official U.S. patent, usually represented by a seven-digit number. But the full story behind most patents is much longer. When a professor found that he was lacking a key tool in his field, he and his colleagues set out to build an alternative that was even better. Their patent was approved in 2021, and this is the story of how it came to be.
