Yao Wang, Ph.D.

Yao Wang, Ph.D., is a principal in the Washington, D.C. office of Fish & Richardson.  Dr. Wang possesses a unique combination of technical expertise in electrical engineering, computer science, biomedical engineering, and physics.  His practice emphasizes post-grant proceedings, patent prosecution, client counseling, and portfolio development.  He manages the portfolios of several mid-sized companies.  He has significant experience in post-grant proceedings, ex-parte reexamination proceedings, reissue applications, and appeals, including conducting one oral argument before the PTAB.  He has participated in various district court and ITC proceedings as well.

Prior to Dr. Wang’s law career, he was a Senior Member of the research staff at Philips Research North America and a Senior Scientist at Pfizer Global R&D. He conducted in-depth research in areas of medical imaging systems, data-intensive image processing, advanced instrumentation, drug discovery and safety, as well as molecular imaging and medicine.

During his doctor’s study, Dr. Wang designed and implemented a 64-element forward-viewing ring-annular array for a commercial intravascular ultrasound imaging system.  The array is capable of both forward and sideward viewing in synthetic aperture mode for real-time imaging of human coronary artery during vascular interventions.  He was the speaker at several IEEE symposia on this topic in Munich, Germany and Honolulu, Hawaii.


While conducting his doctoral research, Dr. Wang also served as a student system administrator at the University of Michigan.  He is very familiar with various operating systems, telecommunication/network technologies, web applications, and programming languages.

During his master’s study, Dr. Wang invented a magnetic resonance imaging (MRI) technique to non-invasively map spatial temperature distribution with a sensitivity of 5 mºC.  He was the recipient of a travel stipend to orally present the results for ISMRM in Sydney, Australia.
