Yunbo Guo, Ph.D., is a patent prosecutor and strategist with over 10 years of prosecution and research experience on optical devices and systems (holography, optical sensors, fiber optics, integrated optics, displays, 3D imaging, AR/VR), laser systems (fiber lasers, optofluidic lasers, laser diodes), semiconductor (memory devices), electronics (microcontrollers, circuits, electric motors), telecommunications, nanotechnology, medical devices, autonomous vehicles, and computer/network technology (blockchain, artificial intelligence and machine learning).

He has drafted and prosecuted hundreds of patent applications and provided strategic counseling, opinion work, due diligence studies, development and management of patent portfolios, and patent litigation support for clients including startups, entrepreneurs, research institutions, and large companies.

Prior to joining Fish & Richardson, Yunbo was a research scientist for Omega Optics Inc., where he conceived and developed a photodetector integrated photonic crystal structure and broadly applied it in acoustic transducer arrays, label-free biosensors, and ultrasound medical imaging systems. He also has previous experience as a research fellow in the department of biomedical engineering at the University of Michigan, where he performed interdisciplinary research in the areas of fiber/capillary systems, optofluidics, Raman spectroscopy, and fluorescence immunoassay.

During his Ph.D. study, Yunbo developed a novel photonic crystal sensor for sensitive biomolecular detection, which a startup company was founded upon. Yunbo has over 30 publications in refereed journals and conferences and holds various U.S. patents.
