Purdue researchers received 172 patents in 2025, ranking 12th among universities worldwide.
An innovation to detect heart rate, respiration and oxygen saturation. An adenoviral vector system for gene delivery. A protein-based adhesive.
These are among the 172 innovations created by Purdue University researchers for which the Purdue Research Foundation (PRF) received patents in the 2025 calendar year from the U.S. Patent and Trademark Office, reflecting Purdue’s status as a global leader in protecting and promoting intellectual property.
Purdue placed seventh nationally and 12th internationally for patents received. The information was published Thursday (February 12) in a report from the National Academy of Inventors. The issued patent, “Adenoviral Vector System for Gene Delivery,” is for the work of Dr. Suresh Mittal, Distinguished Professor of Virology and University Faculty Scholar in the College of Veterinary Medicine’s Department of Comparative Pathobiology, with the Suresh Mittal Lab team.
“Purdue and its robust innovation ecosystem continue to pursue excellence at the highest scale, reflected in our ranking as a top 10 university for U.S. patents received for six years in a row,” Purdue President Mung Chiang said. “Purdue Innovates accelerates support for Boilermaker inventors as they translate breakthrough research into real‑world impact, with outstanding support from the Office of Technology Commercialization.”
The Purdue Innovates Office of Technology Commercialization (OTC) offers services that support the economic development initiatives of Purdue University and benefit the university’s academic activities through commercializing, licensing and protecting Purdue intellectual property.
“Through Purdue Innovates, PRF is committed to ensuring that the university’s innovators, whether faculty, staff or students, have the support they need to bring their ideas from the lab to the marketplace,” said Chad Pittman, president and CEO of PRF. “By helping transform breakthrough research into innovative products and startups, we advance Purdue’s mission while strengthening economic growth and improving quality of life in Indiana and beyond.”
Another Purdue faculty member with ties to the College of Veterinary Medicine on the patent list is Dr. Sherry Harbin, Professor of Biomedical Engineering in the College of Engineering, and a former professor (now professor by courtesy appointment) in the Department of Basic Medical Sciences, for the patent, “3-Dimensional Tissue-Engineered Muscle for Tissue Restoration.”
Brooke Beier, senior vice president of Purdue Innovates, said, “Purdue’s continued leadership in issued U.S. patents is a testament to the strength of our innovation ecosystem. Through Purdue Innovates, we provide end-to-end support — protecting intellectual property, forging industry partnerships and identifying the right commercialization pathways to bring Purdue technologies to market.”
Ken Waite, chief patent counsel and director of intellectual property, said, “Our team takes very seriously its role to protect Purdue intellectual property. This work impacts OTC’s central mission, which is sharing innovations so Purdue inventions can impact the world.”
