Brian Cook is a highly trained patent and technology litigator with a doctorate in nuclear physics from Caltech and nearly a decade of experience in the aerospace industry at NASA’s Jet Propulsion Laboratory. He represents a broad spectrum of clients in various industries including consumer electronics, broadcasting, software, Internet-related technologies, streaming digital media, semiconductors, optical display technologies, and wireless communications. Brian has extensive experience litigating in District Court, before the International Trade Commission, and before the USPTO in inter partes review (IPR) and covered business method (CBM) proceedings. His experience includes patent infringement, trade secret, breach of technology licensing agreement, and standards-essential patent licensing disputes.

Brian worked as an engineer, technical group supervisor, and project element manager at the Jet Propulsion Laboratory in the Mars Program for eight years prior to joining O’Melveny. He led the design team that developed the telecommunications system for the Spirit and Opportunity rovers that landed on Mars in 2003 and subsequently was awarded a NASA Exceptional Achievement Medal. Brian then managed a group of more than forty engineers developing the flight avionics subsystem for the Mars Curiosity rover. Brian is also experienced in telecommunications systems engineering, flight transponder development, flight radar hardware design and development, radio-frequency integrated circuit (RFIC) design, digital signal processing, digital ASIC and FPGA design, and software development.
