David W. Su

Practice profile — David W. Su

David W. Su is an in-house patent executive rather than a courtroom litigator. He serves as Corporate Senior Vice President and General Counsel of MediaTek, Inc., the Taiwan-based fabless semiconductor company, where he oversees MediaTek's legal and intellectual-property functions worldwide. His subject-matter context is semiconductor technology — system-on-chip (SoC) design, multi-core processor architecture, and wireless/consumer chip products. His sole tracked appearance reflects that role: Redstone Logics LLC v. MediaTek, Inc. et al. (W.D. Tex., No. 7:24-cv-00029), where he is listed as in-house counsel on the defendant side (defendant appearances: 1; plaintiff: 0).

The tracked matter typifies his practice: defending a large operating company against an NPE/PAE suit. Redstone Logics (represented by Russ August & Kabat) alleged that MediaTek's ARM DynamIQ-based processors, including the Dimensity 9000+ SoC, infringed U.S. Patent No. 8,549,339 covering power and clock management between processor core groups. The parties filed a joint motion to stay all deadlines on April 18, 2025, having reached an agreement in principle to resolve the case — i.e., a settlement — with outside counsel Pillsbury Winthrop Shaw Pittman handling the district-court filings. Parallel proceedings included MediaTek's own IPR2025-00085 petition challenging the same patent, consistent with a coordinated defense strategy run under Su's legal leadership, though no source shows him appearing personally before the PTAB.

Before joining MediaTek, Su was a senior director at Taiwan Semiconductor Manufacturing Co. (TSMC), leading legal divisions including intellectual property and business transactions, and earlier was a partner at Lee & Li, Taiwan's largest law firm, specializing in IP and commercial litigation. He holds an LLB from National Taiwan University, an LLM from Harvard Law School, and an SJD from the University of Wisconsin Law School, and is active in IP licensing organizations (president of LES Chinese Taipei; board member of APIPA and the Cornerstone Intellectual Property Foundation). He is based in Taiwan and is not identified as counsel of record in U.S. district court or PTAB proceedings; no U.S. state bar admission was verifiable from available sources.
