Overview

His experience spans patent, copyright, trademark, trade secret, and related commercial litigation involving intangible assets such as code, content, data, know-how, reputation, and market position. He has worked on matters across a wide range of technologies, products, and creative assets, including semiconductor architecture, memory systems, autonomous vehicle technology, wireless communications, camera design, footwear, motorcycles, copyrighted works, and fashion brands.

Sean represents clients through every stage of litigation, from early case strategy and resolution through trial and appeal.

Drawing on his litigation experience, Sean also advises clients on how to avoid disputes before they become lawsuits, manage litigation risk when conflict is unavoidable, and address critical aspects of high-stakes transactions. He helps clients assess potential exposure, preserve strategic options, and make business decisions with an informed view of how those decisions may be scrutinized in litigation.
