Sebastian E. Kaplan
Sebastian Kaplan litigates disputes involving construction, commercial transactions and contracts, intellectual property (copyright, trademark, trade secrets), and policyholder-side insurance. He also counsels clients on procurement and competitive bidding compliance.
Sebastian represents clients in federal and state courts and has resolved claims through trial, arbitration, and appeal. He has tried two cases as first-chair and has extensive pre-litigation and pre-trial experience, simultaneously balancing high-stakes litigation with cease and desist disputes, subpoena responses, and numerous commercial disputes. Sebastian has managed document collection in several major litigations that involved complex ESI issues, including identification and forensic collection of documents from mobile devices and collaborative databases.
Sebastian clerked for the Honorable Carlos T. Bea at the U.S. Court of Appeals for the Ninth Circuit from 2009-2010.
