Karrie E. Washenfe Wheatley — Patent Litigation Profile

Karrie E. Washenfe Wheatley (practicing as Karrie Wheatley, Ph.D.) is a patent litigator and Principal in the Houston office of Fish & Richardson P.C., where she has spent her entire legal career since joining after her 2015 graduation; she was elevated to Principal in January 2023. Her practice spans district-court patent litigation, Section 337 proceedings at the U.S. International Trade Commission, and inter partes and post-grant review at the PTAB, with a particular focus on Hatch-Waxman defense for branded pharmaceutical companies and representation of a major academic research institution. Her technology docket is broad — semiconductors (including FinFET design), graphics processing units, consumer electronics, oil-and-gas and hydraulic-fracturing technology, medical devices (CPAP masks, ophthalmic formulations), and personalized cancer medicine — a range her firm attributes in part to her Ph.D. in nutritional sciences and prior breast-cancer research at MD Anderson Cancer Center.

Her work is overwhelmingly defendant-side, representing operating companies against patent-owner plaintiffs. Her single tracked appearance is counsel for Taiwan Semiconductor Manufacturing Company (TSMC) in Advanced Integrated Circuit Process LLC v. Taiwan Semiconductor Manufacturing Co., Ltd., No. 2:24-cv-00623-JRG (E.D. Tex., filed Aug. 2024), a semiconductor-process patent case consolidated with a parallel action against UMC (No. 2:24-cv-00730) and related to a later case, No. 2:25-cv-00324-JRG. The matter is ongoing and paired with a coordinated TSMC IPR campaign (e.g., IPR2025-00830; IPR2025-01302) against the NPE plaintiff's patents; a July 2025 stipulation signed by Wheatley reflects TSMC's strategy of narrowing or staying the district-court litigation pending PTAB institution decisions. No verdict or final resolution in the tracked matter was verifiable in public sources, and I found no reported trial outcomes attributable to her individually.

PTAB/IPR experience: Wheatley regularly appears in IPR and PGR proceedings, per her firm bio, and is actively engaged in the parallel TSMC IPRs described above. Bar / education: Licensed in Texas (2015); J.D., University of Houston Law Center (2015); Ph.D. (nutritional sciences, 2010) and B.A. (humanities, 1999), University of Texas at Austin. She is recognized in Best Lawyers "Ones to Watch" and Super Lawyers "Rising Stars."
