Yuanfeng Gao, Ph.D., is a patent agent in Sterne Kessler’s Electronics Practice Group. Yuanfeng is experienced in drafting and prosecuting patent applications utilizing a wide range of electrical technologies. He also assists in litigation matters at the Patent Trial and Appeal Board. Yuanfeng has particular expertise in semiconductor devices, photolithography systems, thin film growth/characterization, microfabrication techniques, superconducting material and devices, and cryogenic systems.

Yuanfeng received his M.S. and Ph.D. in physics from the University of Wisconsin – Madison. His doctoral research focused on low-loss superconducting quantum bits. He was directly involved with designing and fabricating Josephson phase qubits incorporating crystalline silicon nanomembrane, superconducting through-silicon vias, and microwave resonators with low-loss dielectric material. He also has seven years of microfabrication experience, including hands-on experience with material deposition/etching and photolithography processes. He is a member of the American Physical Society and IEEE.

Yuanfeng earned his J.D. from the Antonin Scalia Law School, George Mason University, and his B.S. in microelectronics from Nankai University in Tianjin, China.
