Chaoxuan "Charles" Liu — Patent Litigation Summary

Liu is an electrical-engineering-trained patent litigator (PhD, EE) whose practice centers on high-technology disputes involving semiconductors, integrated circuits, telecommunications, software, and AI-driven technologies. His work spans federal district courts, the ITC, and the PTAB, with a reputation for integrated multi-forum strategy. In his only tracked appearance, Advanced Cluster Systems, Inc. v. Advanced Micro Devices, Inc. (W.D. Tex., 7:24-cv-00244), he appeared pro hac vice for defendant AMD in an NPE-style infringement suit — consistent with a practice that primarily defends operating companies against patent assertion entities.

Liu is currently a Member in the Intellectual Property Litigation practice at Mintz (Washington, DC office), per his firm profile. At the time of the tracked case he was of counsel at Winston & Strawn's Dallas office; he earlier practiced in the Dallas offices of two other large firms — including Baker McKenzie, per his Texas bar registration — in both litigation and prosecution roles, and worked as a patent agent before law school. He is admitted in Texas only (USPTO Reg. No. 76,616).

His most notable verified work came as part of the Winston & Strawn team that won a complete ITC victory for AMD against Realtek Semiconductor (Jan. 2024, featured in Am Law Litigation Daily's "Litigator of the Week"): the ALJ found two patents invalid, the third not infringed, and — a rare outcome — no economic prong of the domestic-industry requirement. He regularly serves as PTAB back-up counsel for AMD and Intel in IPRs, including IPR2023-00789 (AMD v. Realtek) and IPR2025-00913/00915 (Intel & AMD v. Advanced Cluster Systems). His Mintz bio also cites an eight-figure district court verdict and ITC trial victories (self-reported, not independently verified).

Bar / education: Texas bar (2018); J.D., magna cum laude, SMU Dedman School of Law (2018); Ph.D. and M.S. in electrical engineering, Louisiana State University; B.E. in automation, Huazhong University of Science & Technology.
