Lucas Chang

Lucas S. Chang serves as Vice President, Deputy General Manager, and General Counsel at United Microelectronics Corporation (UMC), a leading global semiconductor foundry, a position he has held since 2018. His practice focuses on intellectual property, deeply rooted in the semiconductor and electronics industries, as well as chemical and pharmaceutical sectors. UMC's patent portfolio encompasses advanced integrated circuit production, logic and memory chips (including DDR4, SSD, DRAM, MRAM, and RRAM), ultra-low power platforms for IoT applications, and automotive ICs. Prior to his in-house role, Dr. Chang was a senior partner at Morgan, Lewis & Bockius LLP, where his practice included intellectual property, general corporate, cross-border investment, and M&A transactions. He also held roles as an associate and partner at Coudert Brothers LLP, Wilson Sonsini Goodrich & Rosati PC, and Heller Ehrman White & McAuliffe LLP, and served as a patent agent and staff attorney at IBM Intellectual Property and Licensing Services.

As in-house counsel, Dr. Chang's role involves safeguarding UMC's extensive intellectual property, necessitating engagement on both the plaintiff and defendant sides of patent disputes. While the provided case data lists a single defendant-side appearance in an "Untitled case" for UMC, his broader responsibilities encompass managing a substantial global patent portfolio and defending against infringement claims, as well as initiating actions to protect UMC's proprietary technologies. UMC has been both a plaintiff and defendant in significant patent and trade secret litigation, highlighting a comprehensive approach to IP protection.

Notably, Dr. Chang was involved in the high-profile patent and trade secret disputes between UMC and Micron Technology. UMC filed a patent infringement lawsuit against Micron in China in 2018, which later resulted in a global settlement in 2021, with UMC making a one-time payment to Micron. This was intertwined with a U.S. Department of Justice investigation into trade secret theft, where UMC pleaded guilty in 2020 and was fined $60 million, agreeing to cooperate in the prosecution of its co-defendant. He has also overseen UMC's strategic IP management, which led to the company achieving AA-level certification for its Taiwan Intellectual Property Management System (TIPS). While his specific appearances in PTAB or IPR proceedings are not publicly detailed, his role as General Counsel for a major semiconductor company suggests oversight of such proceedings as part of a comprehensive IP strategy.

Dr. Chang holds a Ph.D. from the University of Washington (1983) and a J.D. from Santa Clara University School of Law (1994). He is admitted to practice in California and is proficient in Chinese.
