Sean Gloth

I'll research this attorney's background and practice.

Let me search for more details on his prior firm history and the IPValue case.

Let me search for the IPValue case details and his prior firm affiliation.

Practice summary — Sean Gloth (Associate, Latham & Watkins)

Sean Gloth is an intellectual property litigation associate in Latham & Watkins' Washington, D.C. office (moved from the firm's New York office in 2025), and a member of Latham's IP Litigation practice group including its ITC trial group. Drawing on a BSE in computer engineering, he concentrates on patent and trade-secret disputes in electronics-heavy technologies — semiconductors, memory/storage, consumer electronics, digital signal processing, telecommunications, artificial intelligence, and cryptocurrency — rather than pharma or mechanical work. His firm bio also highlights substantial Section 337 experience at the International Trade Commission, plus appearances before the Federal Circuit, the PTAB, and district courts nationwide.

Side orientation. His practice is predominantly defensive: his one tracked appearance is as defendant-side associate for Western Digital in IPValue Management, Inc. v. Western Digital Corp. (C.D. Cal., 8:25-cv-00119), an NPE suit over former Cypress Semiconductor patents covering 3D NAND flash memory in SSDs, embedded flash, and memory cards (filed January 2025; later extended to Sandisk). Most verifiable engagements — for MediaTek, Hanwha Solutions, KeyMe, Mercedes-Benz, and the Uniswap Foundation — were also defenses of operating companies, though his ITC work for Mimir and a vaporizer-cartridge exclusion-order matter show some plaintiff-side capacity. Matters marked "prior to joining Latham" indicate earlier firm experience, but that firm is not publicly confirmed.

Notable matters and results. Verified highlights include: a complete defensive victory for KeyMe against The Hillman Group in the Eastern District of Texas; invalidation of all challenged claims of seven Carucel Investments patents at the PTAB in Mercedes-Benz USA, LLC v. Carucel Investments, forcing dismissal of the parallel district court suit; post-trial resolution for MediaTek against NXP in an ITC investigation; a defensive ITC win for Hanwha Solutions; and a defense win for the Uniswap Foundation in a closely watched DeFi patent case (S.D.N.Y.) that earned Litigator of the Week runners-up recognition in February 2026. He was named a Super Lawyers Rising Star (2024–2026).

PTAB/IPR experience. Gloth has active PTAB experience — most prominently the seven-patent Carucel invalidation — but his practice centers on district court and ITC litigation rather than high-volume IPR work.

Bar and education. Barred in New York (2016) and the District of Columbia; JD, Brooklyn Law School (2015); BSE in Computer Engineering, Loyola University.
