Dr. Yury Kalish is a patent attorney who applies his legal and industry experience to strategically and efficiently support clients in a wide range of technologies. His practice focuses on intellectual property law including patent litigation, patent prosecution, and IP counseling. Yury works on patent infringement actions in federal district courts and the ITC, inter partes reviews (IPR) at the USPTO, prosecution of U.S. and foreign patent applications, and IP portfolio due diligence.

Yury has worked on matters for Cree, Hologic, Qualcomm, SAP, and others in the broad range of technologies including semiconductors, telecommunication, automotive, LEDs, medical devices, and software. He helped draft one of the first successful venue transfer motions after In re Heartland, which moved the case into the client's home district. Yury is a regular contributor to the Firm's ITC Blog.

Prior to joining Jones Day, Yury worked in the automotive industry in Detroit, Michigan and in the federal government. He was a technology development manager at the U.S. Department of Energy and an engineering group manager at Daimler Trucks North America. Yury's Ph.D. dissertation focused on design and development of high-voltage multilayer ceramic piezoelectric actuators. He is a named inventor on three U.S. patents and an author or coauthor of several technical papers on diesel engines, advanced materials, and electronic controls. This background allows Yury to understand clients' business goals, engineering development processes, and product portfolios in support of patent litigation and prosecution matters.
