J. Mark Gidley

J. Mark Gidley is a distinguished legal professional, primarily recognized for his extensive practice in antitrust and competition law. He currently serves as the Chair of the Global Antitrust/Competition practice at White & Case LLP, a position he has held since 1995. His career is marked by significant involvement in high-stakes civil and criminal antitrust cases, including merger clearance, cartel investigations, and monopolization claims, often with a transnational focus. He notably served as Acting Assistant Attorney General for the US Department of Justice Antitrust Division from 1992-1993, overseeing all civil, criminal, and merger matters.

While his primary focus is antitrust, Mr. Gidley has experience with patent-related issues within an antitrust context, such as defending against allegations of "sham" patent litigation where antitrust counterclaims were dismissed. According to authoritative data, he also appeared as an attorney for the plaintiff in one tracked patent litigation, Skyworks Solutions, Inc. et al. v. Grand Chip Labs Inc. et al., affiliated with Arnold & Porter Kaye Scholer. Skyworks Solutions, Inc. is a leader in semiconductors for mobile communications, suggesting experience with technology in this sector. However, public professional profiles consistently list his tenure at White & Case since 1995, without mention of Arnold & Porter, indicating this may have been a specialized or earlier engagement not broadly representative of his career focus. His sole tracked patent litigation appearance was on the plaintiff side.

Specific information regarding Mr. Gidley's regular involvement in Patent Trial and Appeal Board (PTAB) or inter partes review (IPR) proceedings is not readily available in public professional summaries.

Mr. Gidley earned his J.D. from Columbia University School of Law in 1986, where he was a Harlan Fiske Stone Scholar and Notes & Comments Editor for the Columbia Law Review. He is licensed to practice in Texas and is a member of the New York Bar.
