Changing lives through inventions: Purdue jumps to the top 5 of global leaders in US patents received

Purdue University researchers tallied 192 US patents on their inventions in 2022

WEST LAFAYETTE, Ind. – Exciting and dynamic inventions discovered and developed by Purdue University researchers are improving people’s lives around the world.

A system that processes agricultural field images for remote phenotype measurements. A 3D printer that continuously prints structures as small as 100 nanometers. A process that produces butylene, propylene and ethylene from natural gas liquids in shale gas. These are just a few influential Purdue innovations that were patented in 2022, further cementing Purdue’s place as a global leader among its peers in protecting intellectual property.

In 2022, Purdue Research Foundation received an impressive 192 patents from the U.S. Patent and Trademark Office (USPTO), placing it fifth internationally. The top-five breakthrough comes on the heels of Purdue’s No. 6 ranking in both 2020 and 2021, when it received 175 and 169 patents, respectively. The newest ranking was released Wednesday (April 26).

The reporting includes multiple campuses in the same system as one (e.g., the University of California system, with 10 campuses, and the University of Texas system, with eight campuses), and international universities (e.g., King Fahd University of Petroleum and Minerals in Dhahran, Saudi Arabia). In terms of single American university campuses, the top 5 are Massachusetts Institute of Technology, Purdue University, Stanford University, Harvard University, and California Institute of Technology.

The information was published in a report from the National Academy of Inventors.

“In achieving our highest annual ranking of U.S. patents so far, Purdue, along with MIT, stand out as single American campuses without medical schools that count among the most active in inventions,” said Purdue President Mung Chiang. “Boilermaker inventors are colleagues and students who translate their knowledge creation through a foundation for direct impact to society. Half of the equation in the recently launched Purdue Innovates is to provide the best support for them to disclose inventions, apply for and receive patents, and license and deploy these patented inventions.” 

The Purdue Research Foundation Office of Technology Commercialization manages the technology transfer process to vet, protect and license innovations developed by university researchers, including filing patent applications. Its technology portfolio covers innovations in subject areas including agriculture, biotechnology, chemistry and chemical analysis, computer technology, engineering, food and nutrition, green technology, micro- and nanotechnologies, and more.

Brian Edelman, president of Purdue Research Foundation said, “Purdue Research Foundation provides resources to support faculty, staff and student researchers across all academic disciplines and campuses who want to commercialize their inventions. These commercialization resources bring this leading-edge and most modern work to the public, where it can strengthen quality of life and economic and workforce development.”

Brooke Beier, senior vice president of Purdue Innovates said, “We wanted to create an ecosystem that embraced all Boilermakers by supporting both Purdue-owned intellectual property and startups that have their own intellectual property but have some other connection to Purdue, such as an alum. Solidifying the university core while engaging and leveraging the Boilermaker network is key to enhancing Purdue’s ability to become the preeminent university in commercialization and startup success.”
