Biography

As co-chair of the firm’s antitrust and competition practice, Ian Simmons has been lead counsel in more than 30 multi-district litigation (MDL) antitrust proceedings and has achieved precedent-setting results, including winning summary judgment in December 2017 on behalf of Samsung Electronics in the long-running In re Optical Disk Drive litigation in which class plaintiffs were seeking $3 billion in trebled damages. In addition to his extensive experience with cartel cases, Ian litigates matters involving intellectual property issues, including the competitive implications of standard essential patents and FRAND obligations, and has a track record of representing major multinational clients including Marriott International, Asiana Airlines and Kumho Petrochemicals in high-stakes cartel cases. He pays particular attention to global economic pressures that may affect his clients and has taken more than 30 depositions of economists.

An alumnus of the US Department of Justice antitrust division, Ian has argued before the US Court of Appeals in five circuits and tried seven cases to verdict, which earned him recognition by Law360 as MVP of the Year in 2011. Ian is lead counsel to Bitcoin.com in the first antitrust case filed in the crypto currency industry; he also is lead counsel to Samsung Bioepis in the Humira litigation, the first reverse payment case in the bio-similar industry. 

Chambers USA regularly ranks Ian for his work in antitrust litigation and notes his “fine reputation for his multi-jurisdictional cartel defence work.” According to the guide, clients describe him as “outstanding and incredibly skilled,” commend his “detail-oriented work” and praise his “encyclopaedic knowledge.” Ian is consistently recognised for his work in antitrust by The Legal 500, which labels O’Melveny’s team “top-drawer,” and by Global Competition Review, which recently lauded him for his Samsung victory against Qualcomm in 2017 and shortlisted him for Litigator of the Year at the 2015 Global Competition Review Awards. Ian was also named a 2017 National Law Journal “Antitrust Trailblazer.” According to Who’s Who Legal: Competition, Ian “impresses peers and clients alike who consider him a ‘super smart litigator with great instincts.’ One client speaks highly of ‘his superb attention to detail, excellence in written and oral advocacy, and subtle judgement on strategy.”

In a significant recent pro bono effort, Ian represented the Giffords Center for Gun Control in the US Court of Appeals for the DC Circuit, in a winning effort to ban bump stocks which convert weapons into automatic firearms.
