Shannon Yi focuses on patent litigation and pre-litigation strategies as well as patent preparation and prosecution related to electrical and electronic technologies. She has experience in global patent portfolio management, international and domestic patent prosecution, and client counseling. Shannon’s practice further extends to providing legal opinions, including patentability, freedom-to-operate (FTO), as well as invalidity and infringement analysis.

Shannon’s litigation experience spans multiple phases of patent disputes, from pre-suit investigations through trial. She prepares invalidity and noninfringement contentions; develops claim construction strategies; drafts motions and legal briefs; prepares depositions for fact and expert witnesses; primes technical experts for trial; and handles pre- and post-trial submissions. She also drafts petitions for inter partes review (IPR).

In addition to drafting and prosecuting hundreds of patent applications, Shannon has overseen the process and provided guidance. Various technology areas she has worked with include semiconductor devices; semiconductor manufacturing and fabrication; semiconductor inspection technologies; power electronics; artificial intelligence (AI); machine learning (ML); integrated circuit (IC) design; distributed data storage systems; memory devices; mobile devices; medical devices; consumer electronics; aerial vehicles; unmanned aerial vehicles; business methods; 3D printing; financial services; e-commerce; shipping and logistics; video game hardware; and audio systems and devices. Shannon worked for several years at the U.S. Patent and Trademark Office (USPTO), examining patent applications involving semiconductor technology, including semiconductor devices and semiconductor processes.

Prior to her legal career, Shannon worked for Xerox as a chemical engineer. She worked in the laboratories, the pilot plant, and the manufacturing plants to develop, analyze, and optimize designs and manufacturing processes for Xerographic Emulsion Aggregation chemical toners. Her research on chemical toners included the study of colloidal stability, surface ionization, triboelectric charge distribution, additive formulation, and optimization of particle size and circularity.

Shannon devotes time to pro bono matters. She represents clients seeking asylum through the firm’s partnership with Human Rights First. Shannon has been recognized on the Capital Pro Bono High Honor Roll.

Experience

In the Matter of Certain Semiconductor Devices and Products Containing the Same

Achieved a comprehensive victory for respondent Innoscience, a global leader in gallium nitride (GaN) power devices, in a high-profile patent dispute before the U.S. International Trade Commission (ITC). The ITC’s Final Determination confirms that Innoscience avoided all patent claims asserted by Infineon.
