The University of Utah has been named to the National Academy of Inventors’ (NAI) 2025 Top 100 Worldwide Universities Granted U.S. Utility Patents, ranking 81st globally with 46 U.S. utility patents awarded in 2025, recognizing the university’s continued leadership in translating research into real-world impact.
Released annually since 2013, the Top 100 Worldwide ranking highlights universities that play a critical role in the global innovation ecosystem by protecting and commercializing intellectual property. Institutions on the 2025 list collectively hold more than 9,300 U.S. utility patents.
“This recognition reflects the University of Utah’s commitment to discovery and to the responsible stewardship of research with real-world potential,” said Erin Rothwell, Vice President for Research at the University of Utah. “Patents help protect innovations so they can be developed thoughtfully and shared in ways that ultimately serve people, improve lives, and advance the public good.”
Notable University of Utah Patents from 2025
The University of Utah secured several U.S. utility patents in 2025 spanning multiple disciplines, including health, engineering, and advanced research tools. Selected examples include:
U-7334 Cannulated Continuous Compression Screw
Inventors: Wade Fallin, Charles Saltzman, Colin Gregersen, Chase Hagman
Department: Orthopedics
A specialized bone screw designed for insertion into bone during orthopedic procedures. The screw includes a distal member with bone-engaging threads and a proximal member that slidably engages the distal member. A tension member extends between them so that when the distal and proximal parts move relative to each other, the tension member elongates and urges the distal part back toward the proximal part, thereby applying z across a bone interface (helping stabilization and healing). The design also allows a guidewire to pass through a cannula and may include mechanisms to limit screw length and transmit bending loads.
U-7333 ISOLATION, STORAGE, AND DELIVERY OF EXTRACELLULAR VESICLES USING ASYMMETRIC DEPTH FILTERS
Inventors: Misha Skliar, Vasily Chernyshev
Department: Chemical Engineering
A system and method for isolating, storing, and delivering extracellular vesicles (EVs) using asymmetric depth filters. The invention focuses on passing a fluid containing EVs (or other particles) through a specially designed depth-filter medium with graduated pore sizes that can capture these tiny particles. Once captured, the EVs can be stored under conditions that preserve them (e.g., hydrated, dried, frozen) and later released in a controlled way. Depending on the design of the depth filter, delivery of EVs can occur passively (through diffusion) or actively (using applied forces such as pressure or fields), and the technology can be adapted for various particle sizes beyond EVs.
U-7368 SEMI-ACTIVE ANKLE AND FOOT PROSTHESIS POWERED BY A LOCKABLE SERIES-ELASTIC ACTUATOR
Inventors: Tommaso Lenzi, Samuel Westgard, Minh Tran, Lukas Gabert, Connely Buchanan
Department: Mechanical Engineering
A semi-active foot and ankle prosthesis that uses a lockable series-elastic actuator and a selectively engageable locking mechanism to improve prosthetic function and adaptability. The invention includes a drive motor coupled to a linear actuator that moves the prosthetic foot relative to the ankle frame, as well as a locking mechanism that can engage the motor’s drive shaft to resist back-driving forces. This design enables the prosthesis to switch between an active mode (with powered motion for lower-torque activities) and a passive mode (with the locking mechanism engaged to resist higher-torque loads), while maintaining a compact structure suitable for integration within the foot shell.
