David B. Conrad, Fish & Richardson P.C.

David B. Conrad is a principal in the Dallas office of Fish & Richardson with a practice focused on intellectual property litigation. Drawing on his background as a software and embedded systems engineer, he handles patent disputes across a wide range of technologies, including computer software, semiconductors, e-commerce, artificial intelligence, and telecommunications. His work often involves complex software and hardware integration, such as in the tracked case Greenthread Ltd v. Monolithic Power Systems Inc, which concerns semiconductor devices.

The authoritative case data and public record show Mr. Conrad works exclusively on the defense side. His firm biography notes that he represents companies accused of infringement and has a reputation for defending clients against patent assertion entities (PAEs). Rankings from Managing Intellectual Property and DocketNavigator have previously listed him among the top attorneys for representing defendants in patent cases. This defense-side focus is consistent with his role as lead counsel for the defendant in the Greenthread matter.

Mr. Conrad has secured numerous favorable outcomes for defendants in district courts and on appeal. Notable results include obtaining a jury verdict of non-infringement for Ticketmaster, and winning summary judgment of invalidity under 35 U.S.C. § 101 for Bed Bath & Beyond, a ruling affirmed by the Federal Circuit along with an award of attorneys' fees. He also has significant experience before the Patent Trial and Appeal Board (PTAB), where he has argued in inter partes review (IPR) proceedings. The Greenthread district court case was stayed pending IPRs filed by Monolithic Power Systems.

Mr. Conrad has spent his legal career at Fish & Richardson. He earned his J.D. with honors from the University of Texas at Austin School of Law and a B.S. in Electrical Engineering from the University of Texas at Austin. He was admitted to the Texas bar in 2007.
