Andrew Kopsidas, a Principal in the Washington, D.C. office, leads and tries intellectual property cases and offers strategic counseling to clients.

A lead trial lawyer recognized for producing positive results for his clients, Andrew serves his clients by getting to know their business, developing creative and effective solutions, and conducting litigations with uncompromising efficiency. His clients are among the most prominent U.S., Korean, and European companies. He is described by one client as “a unique strategic mind with real courtroom chops.”

Andrew has handled patent and intellectual property matters in the U.S. Court of Appeals for the Federal Circuit, the International Trade Commission, the U.S. Patent & Trademark Office, federal district courts in dozens of states, and arbitrations in a variety of forums. With a background in aerospace and electrical engineering, Andrew has litigated cases involving microprocessors, acoustic devices, DRAM and flash memory devices, mobile phones, telecommunications networks and standards, digital signal processing, internet applications, GPS devices, and various software, mechanical and chemical inventions. He regularly speaks, writes, and advises clients on trade secrets and litigation before the International Trade Commission (“ITC”).

Andrew is at the forefront of Fish’s ITC and Trade Secret practices. He has first-chaired ITC trials, litigated dozens of cases in that venue, and is a regular speaker on ITC practice and procedure, including the strategic use of ITC litigation in parallel with district court litigation. He has been recognized as a “Leading ITC Lawyer” by The Legal 500.

When he’s not helping clients achieve their business goals, Andrew takes pride in training junior lawyers and donating his time to pro bono causes. Andrew is an instructor for the National Institute for Trial Advocacy (“NITA”) courses on trial and deposition skills. He also dedicates a significant portion of his time to matters for the Veterans Consortium, Washington Lawyers’ Committee for Civil Rights and Urban Affairs, and The Human Trafficking Legal Center. In 2019, The Human Trafficking Legal Center honored Fish with its “Litigation Firm of the Year” award for Andrew’s successful trial securing a victim of human trafficking a $1.5 million judgment—one of the largest awards ever achieved in this type of case.

Before going to law school, Andrew worked at NASA for approximately five years. During that time, he worked on several Space Shuttle missions as a Flight Controller and Systems Engineer.  He also worked as an Aerospace Design Engineer at the U.S. Naval Research Laboratory in Washington, DC, where he worked on the design of a small, chine-body drone aircraft that would have the radar cross-section of a full-sized aircraft to enemy radar.
