Joseph B. Warden

Joseph B. Warden is a Principal at Fish & Richardson in Delaware, where his practice focuses on high-stakes patent and commercial litigation. He is a first-chair trial lawyer with significant experience in the life sciences sector, handling complex cases involving pharmaceuticals and medical devices. In addition to life sciences, Warden has litigated matters related to semiconductors and other complex technologies. He has developed a notable track record in disputes centered on patent damages, including those involving standard-essential patents.

According to his firm biography, Warden represents both plaintiffs and defendants. The provided case list shows him representing the defendant in Greenthread Ltd v. Monolithic Power Systems Inc, a case concerning semiconductor technology. His notable public results include successfully defending a major pharmaceutical company in a damages-only trial, resulting in a jury award of less than 10% of the billions sought, and securing a verdict of less than 2% of damages sought in a separate medical device case. He has also led cases for patent holders that resulted in eight-figure jury verdicts and nine-figure settlements.

Warden has been with Fish & Richardson for his entire patent litigation career, having been elevated to Principal in 2017. The Greenthread case he handled for Monolithic Power Systems was stayed pending the outcome of inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), which were initiated by his client. This indicates experience coordinating district court litigation strategy with PTAB challenges.

He earned his J.D. from the University of Virginia School of Law in 2009, where he was a member of the Order of the Coif, and a B.A. from Brigham Young University in 2005. He was admitted to practice in 2009.
