David Cooperberg is an associate in the firm's litigation department. His practice focuses on patent litigation in federal district courts, as well as post-grant proceedings in the U.S. Patent and Trademark Office. His experience encompasses a broad spectrum of technologies, including semiconductor design and manufacturing, solid-state memories, wireless, cable and fiber-based networking, LEDs, and automotive entertainment systems.

Dr. Cooperberg has a technical engineering background. He served as a staff process and modeling engineer at Lam Research Corporation for 10 years, where he designed, implemented, and maintained a semi-empirical profile simulator for modeling feature evolution during plasma processing of integrated circuits. He also provided electromagnetics, fluid dynamics, and plasma discharge modeling support for product development using commercial, university and internally developed codes, and he developed algorithms for an interferometric endpoint system.

While earning his doctorate in physics, Dr. Cooperberg served as a research assistant in the Electronics Research Laboratory of the University of California at Berkeley, where he conducted computer simulations of surface wave sustained plasma discharges. He was also a research assistant in the Lawrence Berkeley Laboratory where he researched quantum effects in low temperature superconducting circuits.

Dr. Cooperberg is the co-author and named inventor on six U.S. patents involving innovations in the field of plasma process development and plasma processor design. He has also authored or co-authored several publications on various topics relating to plasma processing of semiconductors including plasma reactor modeling and feature scale profile simulation.
