Cooley Expands Tech Regulatory and Defense Practice

Washington, DC – November 3, 2025 – Janet Kim and Sean Quinn have joined Cooley as partners in the firm’s global litigation department in Washington, DC. Their practices focus on online safety and artificial intelligence (AI) regulatory defense for global technology companies, especially in the European Union and UK, where this practice is burgeoning.

“Cooley is developing a leading practice for the representation of tech companies in Europe, in regulatory counseling, government enforcement and civil litigation,” said Ian Shapiro, partner and chair of the firm’s global litigation department. “Janet and Sean further enhance Cooley’s capacity to advise the world’s leading tech companies on European content regulation, including compliance with the UK Online Safety Act, the EU Digital Services Act and the EU AI Act, as well as to defend against government enforcement of these statutes.”  

Kim and Quinn also have substantial experience defending online safety and AI investigations by government agencies in the UK, EU and US, and Quinn is recognized as one of Chambers & Partners’ 20 Global Market Leaders for AI.

“The recruitment of Janet and Sean is another important milestone in the build of our rapidly growing European tech practices,” said James Maton, co-partner in charge of Cooley’s London office and head of disputes. “Their recruitment will further integrate our European and US teams and enhance our ability to provide seamless regulatory advice across converging and overlapping areas like content regulation, product compliance, privacy and AI regulation.”

In addition to experience in private practice, earlier in her career, Kim served as associate counsel in the White House Counsel’s Office and chief counsel for investigations for the House Committee on Oversight and Reform. Quinn was formerly an investigative counsel for the US House of Representatives.

“Joining Cooley allows us to provide the market-leading counsel our clients deserve – advice that is pragmatic, forward-thinking and creative at every stage of the compliance and enforcement life cycle,” said Kim. “We will immediately leverage Cooley’s unmatched breadth to guide our clients through the rapidly evolving landscape of AI, content and platform regulation.”

Cooley’s litigation department includes 470+ lawyers in the US and Europe and is the leading litigation practice for the representation of tech, life sciences and other innovative companies. In 2025, Cooley has added elite next-generation lawyers to its litigation department throughout the country, including Elizabeth Prelogar, Raymond Tolentino, Ephraim McDowell and Brian Nelson in DC; Simona Agnolucci, Ben Hur, Jonathan Patchen, Eduardo Santacana, Michael Rome, Joshua Anderson and Tiffany Lin in San Francisco; Lyndsey Kruzer in Boston; and James Kim and Tejal Shah in New York.
